Description

NERVE STIMULATION FOR PAIN CONTROL
CROSS-REFERENCE
{0001] This application claims the benefit of U.S. Provisional Application No. 63/375,834 filed September 15, 2022, which is incorporated by reference in its entirety.
BACKGROUND
(0002] Pelvic pain, or pain in the pelvic area, has many causes but commonly involves contraction of pelvic floor muscles and activity of nerves that innervate these muscles. Chronic pelvic pain (CPP) is non-malignant pain perceived in the pelvic area in either men or women that lasts for 6 months or longer. CPP is a complex, multifactorial condition that is very disabling for patients. CPP may come and go or be constant with episodes of exacerbating pain.
SUMMARY
{0003] Chronic pelvic pain (CPP) can impact quality of life, often causing episodes of severe discomfort and exacerbating pain. Common symptoms of CPP include but are not limited to neuropathic symptoms like paresthesia, numbness, burning, lancinating pain, in the pelvic, anus and/or genitals. Episodes of pain associated with CPP may frequently occur with sitting, urinating, defecating, attempts at urinating, attempts at defecating, or sexual intercourse and may be exacerbated with these activities. Approaches to treat CPP by electrically stimulating a large section of the affected area (e.g, pelvic area) or transcutaneously may have limited success at alleviating the symptoms of pain. As such, targeting specific nerves for electrical stimulation that is adapted to the individual’s pain response may provide a highly efficacious treatment for CPP and other pain symptoms.
{0004] Aspects of the disclosure herein provide methods for reducing pain of an individual, the method comprising: (a) implanting a sensor and a stimulator electrode within a pelvic area of the individual; (b) sensing with the implanted sensor a parameter associated with an episode of pain of the individual; and (b) providing an adapted electrical stimulation with the implanted stimulator electrode that reduces pain of the individual, wherein at least one of an intensity, a frequency, or a duration of the adapted electrical stimulation varies according to the parameter detected in step (b). In some embodiments, the stimulator electrode comprises a first stimulator and wherein the first stimulator is implanted at or adjacent to a first anatomical site. In some embodiments, the stimulator electrode further comprises a second stimulator and wherein the second stimulator is implanted at or adjacent to a second anatomical site. In some embodiments, the method further comprises providing a base electrical stimulation with the implanted stimulator electrode before the adapted electrical stimulation is provided. In some embodiments, the adapted electrical stimulation is different from the base electrical stimulation. In some embodiments, at least one of the intensity or the frequency of the adapted electrical stimulation is different from that of the base electrical stimulation. In some embodiments, the adapted electrical stimulation boosts the base electrical stimulation. In some embodiments, the adapted electrical stimulation, alone or together with the base electrical stimulation, reduces the pain of the episode. In some embodiments, the adapted electrical stimulation comprises a first stimulation pattern and a second stimulation pattern, wherein the first stimulation pattern is provided by the first stimulator and the second stimulation pattern is provided by the second stimulator. In some embodiments, the first and second stimulation patterns comprise excitation values for intensity, frequency, phase, pulse width, or any combination thereof. In some embodiments, the first and second stimulation patterns are the same. In some embodiments, the first and second stimulation patterns differ in intensity, frequency, phase, pulse width, or any combination thereof. In some embodiments, the method further comprises using software to generate the first and second stimulation patterns based on at least the parameter. In some embodiments, the generated first and second stimulation patterns are configured to reduce pain of the episode based on at least the parameter.

DETAILED DESCRIPTION
[0023] Chronic pelvic pain (CPP) is a complex condition and involves non-malignant pain perceived in the pelvic area for at least 6 months. CPP can impact quality of life, often causing episodes of severe discomfort and exacerbating pain. Common symptoms of CPP include but are not limited to neuropathic symptoms like paresthesia, numbness, burning, lancinating pain, in the pelvic, anus and/or genitals. CPP comprises episodes of a recurring pain, exacerbating pain, or any combination thereof. [0024] CPP may be associated with various conditions. These conditions include but are not limited to interstitial cystitis, painful bladder syndrome, chronic prostatitis, urethral pain syndrome, vagina pain, vulvodynia, vestibulodynia, radiation vaginitis, penile pain syndrome, proctalgia fugax, anorectal pain (e.g., unspecified functional anorectal pain syndrome), phantom rectum syndrome, levator ani syndrome, pelvic floor muscle pain syndrome, pelvic floor muscle pain dysfunction, pelvic floor myalgia, urethral pain syndrome, coccygodynia, pudendal neuralgia, voiding dysfunction, and constipation. In some cases, these conditions involve the pudendal nerve. In some cases, CPP comprises pain associated with one or more of clinical or sub-clinical inflammation, compression of a nerve ending (e.g., during a striated muscle spasm or an anatomical compression event), neuropathic pain, nerve damage or injury, dysregulated visceral smooth muscle activity. Pain associated with CPP can occur when the individual sits, changes posture, urinates, defecates, attempts to urinate, attempts to defecate, and/or has sexual intercourse. Pain may have diurnal variation in the individual over the course of the day. In some cases, the pain may be exacerbated by activities.
[0025] CPP often relates to neurological issues, making neuromodulation of the central or peripheral nervous system an attractive approach to reduce pain of the affected individuals. Treatments for pain may target the entire body, pelvic area, and/or nervous system rather than specific peripheral nerves within the pelvic area. Such treatments may include providing nerve blockers and/or physical therapy to an individual to help alleviate pain in the pelvic area. Treatments involving electrical stimulation may include transcutaneous electrical nerve stimulation (TENS) therapy, which provides electrical impulses to the pelvic region through electrodes placed on the surface of the skin of the individual, with the goal of alleviating pain in the pelvic area. In some cases, spinal cord stimulation (SOS) has had a limited success in the treatment of back and/or leg pain. SOS may be somewhat limited due to the inability to consistently obtain coverage to most painful areas.
[0026] In some cases, pain usually may persist even if the organ-specific insult is over, so focused organ therapies may be inadequate. As such, neuromodulation of the peripheral nervous system may be a more attractive approach. Especially in cases where the pain areas may be well defined and can be linked to the target site of the peripheral nerve, peripheral nerve stimulation may have high efficacy in treating CPP and pain conditions. In some cases, individuals with CPP who are refractive to conservative care may responds to sacral nerve (SNM), but the success of SNM may vary, especially in patients with pudendal neuralgia. In some cases, pain associated conditions have pudendal nerve involvement. Thus, electrical stimulation of the pudendal nerve, whether alone or in combination with other nerve targets, has the potential to be an efficacious approach to reducing pain.
[0027] Many electrical nerve stimulation approaches currently used deliver a preset stimulation protocol (i.e., open-loop configuration) and usually are not able to adapt to the changing parameters of pain experienced by the individual. In some cases, the inability to adapt the stimulation can result in overstimulating or under stimulating the target area and lead to inefficient or inadequate pain management. Moreover, because treatments usually do not adapt to the changing parameters of pain, existing pain management often requires patient-actuation during bouts of exacerbating pain to provide pain relief. Therefore, it would be highly beneficial to provide electrical stimulation to peripheral nerve targets that adapt to innate feedback from the subject as conditions change (i.e., a closed-loop configuration). 0928] Provided herein are devices, systems, and methods for preventing and/or reducing pain associated with an episode of pain in an individual in need thereof. The systems, methods, and devices, described herein are directed to treating episodes of pain associated with chronic pelvic pain (CPP) or other conditions resulting in pelvic pain using peripheral nerve stimulation. In some embodiments, the systems, methods, and devices, comprise a closed-loop configuration. In some embodiments, adapted stimulation to the target nerves are provided by an implanted stimulator with an underlying physiological rationale comprising: (a) stimulating motor fibers to alter end organ muscle activity where peripheral pain is driven by spasm and/or hypertonicity (e.g., pelvic floor myalgia, some cases of bladder pain syndrome, and urethral pain associated with motor modulation); (b) stimulating larger diameter afferent fibers to modulate spinal gating of nociceptive signaling from peripheral foci of pain generation (e.g., interstitial cystitis, coccygodynia, and pelvic myalgia); (c) blocking nerve conduction (e.g., anodal block) to (i) directly block disease-related peripherally driven pain, and (ii) block noxious effects associated with providing the adapted stimulation, which facilitates higher charge delivery for therapeutic benefit; and any combination thereof.
[0029] In some cases, the individual comprises a female subject, at least 18 years of age with chronic pelvic pain, pressure, or discomfort with moderate to severe pain criteria of greater than or equal to 4 points on the numeric pain rating scale (NPRS). In some cases, the pelvic pain, pressure or discomfort is related to the urinary bladder indicated by: a questionnaire where an individual indicates greater than or equal to one urinary symptom e.g., persistent urge to void or frequency of voiding experienced by the individual for at least 3 months. In some cases, the individual comprises an individual who has experienced a duration of chronic pelvic pain systems less than or equal to 3 months. In some instances, the individual comprises a bladder with normal bladder compliance and no Hunner’s lesion(s) as defined by the American Urological Association (AUA) or the European Association of Urology (EAU). In some cases, individual comprises an individual who has failed or is not a candidate for conversative treatment e.g., pelvic floor muscle therapy, biofeedback, and/or behavioral modification.
[0038] Described herein are targeting one or more peripheral nerves based on the etiology of the pain condition with adapted electrical stimulation to reduce pain experienced by an individual. In some embodiments, the stimulator electrodes target different nerves (e.g., a first stimulator targeting a sacral nerve and a second stimulator targeting a pudendal nerve). In some embodiments, stimulating multiple nerves within the pelvic area may broaden the field of treatment in pain syndromes having diffuse areas of pain. In some embodiments, the electrical stimulation provide may be adapted to provide blocking and stimulation of electrical nerve signals on the same nerve. In some embodiments, stimulator electrodes target one or more locations along a single nerve. In some embodiments, targeting multiple points along a single nerve allows for improved control in the closed-loop modulation (e.g., a first stimulator implanted at or adjacent to a first anatomical site of a pudendal nerve and a second stimulator implanted at or adjacent to a second anatomical site of the pudendal nerve). In some embodiments, targeting a single nerve at multiple sites permits both blocking and stimulation on the same nerve. (0031 ] In some embodiments, the stimulation provided by the electrodes to different anatomical sites may be the same or differ in at least one of intensity, frequency, phase, or pulse width. The stimulation provided by each stimulator may start and/or end at different times relative to the stimulations provided by another stimulator, depending on the pain detected in the individual. In some embodiments, a first stimulator provides a first stimulation pattern and a second stimulator provides a second stimulation pattern, depending on the pain detected in the individual.
(0032] In some embodiments, the electrode provides a basal stimulation to the target nerve before an adapted stimulation (e.g., an electrical stimulation having an adapted stimulation pattern) is provided. In some embodiments, the adapted electrical stimulation is provided by the same electrode that provided the basal stimulation. In some embodiments, the adapted electrical stimulation is provided by a different electrode than the one providing the basal stimulation. In some embodiments, the adapted stimulation provide at least one of: (i) a “boost” of the basal stimulation parameters (e.g., increase the amplitude of the basal stimulation); (ii) a switch to a different stimulation program (e.g., a switch from sacral to pudendal nerve stimulation or a switch from stimulating to blocking frequencies); or (iii) a change from single to dual nerve stimulation (e.g., pudendal stimulation to simultaneous pudendal, sacral and/or pelvic plexus stimulation).
[0033] Provided herein are devices and systems comprising one or more sensors, one or more stimulator electrodes, a processor, a power source, or any combination thereof. In some embodiments, the one or more stimulator electrodes, one or more sensors, a processor, a power source, or any combination thereof may be implanted into the body of the individual. In some embodiments, the device may be placed superficially on the body of the individual. In some embodiments, the device may be implanted into the body of the individual. In some embodiments, the device comprises a wireless transmission module capable of transmitting and receiving wireless data wireless with a remote device (e.g., a mobile phone, a tablet, a computer, etc.). In some embodiments, the device comprises a hermetically sealed connector placed on the individual’s skin superficially that may electrically couple to a remote device by a cable. In some embodiments, the individual or a healthcare professional may modify the settings of the sensor and/or the stimulator electrode (e.g., a threshold parameter and/or signal intensity threshold). In some embodiments, the setting may be modified using a graphical user interface on the remote device. In some embodiments, the device automatically modifies the setting of the sensor and/or the stimulator electrode. In some embodiments, the device may automatically modify the setting of the sensor and/or the stimulator electrode based on a parameter detected by the sensor. In some embodiments, the setting may comprise one or more of sensitivity of the sensor or stimulator, activity of the sensor or stimulator, a length signal acquisition period, a stimulation pattern provided by a stimulator to the surrounding tissue.
[0034] The devices, systems, and methods described herein may prevent and/or reduce pain in an individual by detecting a parameter associated pain in an individual and adjusting an electrical stimulation by one or more stimulator electrodes based on the parameter’s characteristics. In some embodiments, the sensor monitors parameters of the internal environment of the individual for activities associated with episodes of pain (e.g., detecting muscle function by pelvic floor EMG or afferent nerve conduction). In some embodiments, the sensor measures one or more of EMG, ENG, pressure, temperature, blood flow, acceleration, movement, orientation, 3-D spatial location, and physical deformation/stretch at or near the target tissue. In some embodiments, the sensor monitors whether anodal block associated with a basal or an adapted stimulation provided by the device has adequately reduced the pain. In some embodiments, patient actuation is used to indicate an episode of pain. In some embodiments, patient actuation is used to indicate an episode of pain associated with episodic exacerbations (e.g., pelvic floor myalgia) and/or intermittent pain (e.g., proctalgia fugax). In some embodiments, patient actuation is used to indicate an episode of postural pain associated with a CPP condition (e.g., patients with myalgia upon sitting). After the episode of pain is indicated, the electrical stimulation may be provided to reduce pain of the episode. In some embodiments, a boost to a basal stimulation pattern is provided by the adapted stimulation. In some embodiments, the sensor may detect a change in posture of the individual and/or received a patient actuated signal. In some embodiments, circadian functions are used to indicate pain having diurnal variation. In some embodiments, the diurnal variation comprises night-time pain. In some cases, pain is worse at night and/or with movement. In some embodiments, a different stimulation pattern may be provided when the individual wakes compared to when the individual sleeps.
(0035] In some embodiments, a sensor is configured to sense one or more parameters associated with an episode of pain or an attempt by the individual to reduce pain. In some embodiments, the parameter comprises an electromyography (EMG) signal associated with an episode of pain. In some embodiments, the EMG signals are associated with electrical activity of muscles, specifically from action potentials in muscle fibers. In some embodiments, the parameter comprises an electroneurogram (ENG). In some embodiments, an electroneurogram comprises electrical activity from one or more neurons and typically refers to recordings made from bundles of axons in peripheral nerves. In some embodiments, the parameter comprises a change of electric impedance caused by physical deformation of the sensor material. In some embodiments, the physical deformation comprises stretching, compression, or any combination thereof. In some embodiments, the parameter associated with an episode of pain comprises a change in the amplitude, frequency, phase, or any combination thereof one or more of EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signals, or any combination thereof. By providing adaptive electrical stimulation in combination to the basal stimulation and/or individual’s response, the devices, systems, and methods described herein may reduce pain in the individual.
(0038] In some embodiments, the parameter comprises a change in pressure, velocity, acceleration, or 3-D spatial direction. In some embodiments, 3-D spatial direction is determined by GPS signal. The GPS signal, in some embodiments, may indicate and recognize when the individual is in proximity to locations including at least one of the individual’s home, bedroom, living room, dining room, bathroom, or office. In some embodiments, the GPS signal may be configured to modulate the adapted stimulation pattern, described elsewhere herein, based on the GPS coordinates and/or GPS location of the subject. In some embodiments, the GPS signal of a location and/or GPS coordinates may indicate locations to help to predict or indicate certain activities that are commonly associated with an episode of pain. In some embodiments, the change in one or more of pressure, velocity, acceleration, or 3-D spatial direction may indicate a posture or a change in postures of the individual. In some embodiments, changes in pressure may be measured by a pressure sensor. In some embodiments, the pressure sensor comprises a differential pressure sensor, absolute pressure sensor, or any combination thereof. In some embodiments, changes in velocity, acceleration, or changes in 3-D spatial direction may be measured by an accelerometer, gyroscope, magnetometer, or any combination thereof. In some embodiments, the device provides an electrical stimulation using one or more implanted stimulator electrodes that, alone or together with a basal electrical stimulation, reduces pain of an episode. In some embodiments, modulating the adapted stimulation pattern comprises adjusting a detection parameter (e.g., signal intensity threshold) of the classifier, described elsewhere herein.
(0037] In some embodiments, the trigger to start the adapted electrical stimulation is a parameter detected by the sensor. In some embodiments, the trigger to start the adapted electrical stimulation is associated with patient actuation (e.g., sending a signal by the patient to the sensor prior to changing posture, during episodes of pain exacerbation). In some embodiments, the trigger to start the adapted electrical stimulation is a parameter associated with pelvic muscle contraction (e.g., EMG signal and/or ENG signal). In some embodiments, at least one of the basal or adapted electrical stimulation stops being provided when the sensor receives a change in the detected parameter (e.g., a patient actuated signal after the patient finishes urinating or change posture). In some embodiments, the basal and/or adapted stimulation patterns have a finite duration. In some embodiments, the duration of the basal and/or adapted stimulation patterns are determined by the detected parameter. In some embodiments, the basal and/or adapted stimulation patterns last until a change in the detected parameter above or below a threshold.
(0038] In some embodiments, the device may be implanted in the individual in proximity to the pudendal nerve, a sacral nerve, a nerve of the pelvic plexus, or branches thereof. The pelvic plexus may comprise one or more nerves that that innervate tissue involved with urination and/or defecation in a pelvis of an individual. In some instances, one or more nerves of the pelvic plexus may comprise the splanchnic nerve, hypogastric nerve, autonomic plexus nerve, or any combination thereof nerves. The pelvic plexus may comprise one or more parasympathetic and/or sympathetic nerves. In some embodiments, the one or more stimulator electrodes may be placed at or near the pudendal nerve, the sacral nerve, and/or a nerve of the pelvic plexus. In some embodiments, the one or more stimulator electrodes or one or more sensors may be implanted in proximity to a pudendal, sacral, and/or pelvic plexus nerve unilaterally or bilaterally. In some embodiments, the one or more stimulator electrodes or one or more sensors may be implanted unilaterally or bilaterally based at least on the pain or pain episode the individual has experienced or may experience. For example, an individual experiencing unilateral pain may be treated with one or more electrodes implanted at or adjacent to a single nerve, whereas an individual experiencing bilateral diffuse pain may be treated with one or more electrodes implanted at or adjacent to one or more different nerves. In some cases, the one or more stimulator electrodes and/or one or more sensors may be implanted unilaterally at or adjacent a first region of a nerve. In some embodiments, the one or more stimulator electrodes and/or one or more sensors may be implanted bilaterally at or adjacent to a first region nerve and a second region of a nerve where the first and second region are spatially independent regions of the nerve. In some cases, unilateral pain may be treated by implanting one or more electrode leads (e.g., stimulator electrode and sensor electrode) at or adjacent to a trunk and distal pudendal nerve, pudendal and sacral nerve, pudendal and pelvic autonomic nerve, or any combination thereof. In some instances, bilateral pain may be treated by implanting one or more electrode leads (e.g., stimulator electrode and sensor electrode) at or adjacent the pudendal nerve bilaterally, the sacral nerve bilaterally, pelvic autonomic nerve bilaterally. In some embodiments, the one or more stimulator electrodes may be implanted to stimulate motor nerve fibers (e.g., to the pelvic floor). In some embodiments, the one or more stimulator electrodes may be implanted within, proximate, or adjacent to the muscle (e.g., pelvic floor). The implanted sensor may sense a signal that indicates that an individual may exhibit an episode of pain. The device may analyze the signal and classify the signal as a real-time or prospective episode of pain. The device may generate an electrical stimulation that is modulated based on the classified episode of pain and may deliver the adapted electrical stimulation using one or more stimulator electrodes to the target nerve. In some embodiments, the modulation of the electrical stimulation comprises changing the frequency, amplitude, and/or pulse width of electric stimulation. In some embodiments, the modulation of the electrical stimulation comprises a modulation in simulator configuration. In some embodiments, the one or more electrodes comprises one or more stimulation electrodes and one or more sensing electrodes. The one or more stimulation electrodes and one or more sensing electrodes may be configured to switch between stimulating and sensing operations on demand, programmatically, user controlled, medical personal control, or any combination thereof. The electrical stimulation may be modulated to improve the muscle and/or nerve response to prevent or reduce the episode of pain. The modulated electrical stimulation may result in improved muscle response, as measured by response time, muscle function, or other markers of prevention or reduction of pain, to prevent the potential episode of pain. The electrical stimulation may be modulated to reduce a severity and/or duration of an episode of pain. In some embodiments, the electrical stimulation may reduce the intensity or duration of pain.
[0039] In some embodiments, the electrical stimulation reduces the duration and/or severity of the episode of pain as compared without the electrical stimulation. In some embodiments, the electrical stimulation reduces or inhibits a muscle contraction, spasm, twitch, or any combination thereof. In some embodiments, the muscle contraction, spasm, or twitch occurs before or during the episode of pain. In some embodiments, the electrical stimulation comprises the basal and adapted electrical stimulation. In some embodiments, the electrical stimulation comprises the basal stimulation. In some embodiments, the electrical stimulation comprises the adapted electrical stimulation.
[9040] In some embodiments, the stimulator electrode provides a basal electrical stimulation, an adapted electrical stimulation, or any combination thereof. In some embodiments, the electrical stimulation comprises an electrical stimulation provided over a period of time. In some embodiments, the period of time comprises the period of time a subject has a muscle contraction, spasm, twitch, or any combination thereof. In some embodiments, the muscle contraction, spasm, or twitch triggers EMG threshold detection. In some embodiments, the period of time for the electrical stimulation comprises about 1 second to about 30 seconds. In some embodiments, the period of time for the electrical stimulation comprises about 1 second to about 5 seconds, about 1 second to about 10 seconds, about 1 second to about 15 seconds, about 1 second to about 20 seconds, about 1 second to about 25 seconds, about 1 second to about 30 seconds, about 5 seconds to about 10 seconds, about 5 seconds to about 15 seconds, about 5 seconds to about 20 seconds, about 5 seconds to about 25 seconds, about 5 seconds to about 30 seconds, about 10 seconds to about 15 seconds, about 10 seconds to about 20 seconds, about 10 seconds to about 25 seconds, about 10 seconds to about 30 seconds, about 15 seconds to about 20 seconds, about 15 seconds to about 25 seconds, about 15 seconds to about 30 seconds, about 20 seconds to about 25 seconds, about 20 seconds to about 30 seconds, or about 25 seconds to about 30 seconds.

In some embodiments the device configured in a closed-loop configuration may measure inertial signals such as rapid acceleration, shock, posture-orientation, or any combination thereof via the one or more sensors 120 to detect one or more parameters associated with an episode of pain. In some embodiments, the one or more parameters associated with the episode of pain comprise signals from actions including coughing, sneezing, laughing, or exercise. Once detected, the implantable pulse generator 118 may provide an adapted electrical stimulation pattern 124 to reduce pain of the individual based on the one or more parameters. In some embodiments, the threshold level for detecting parameters may be modified and adjusted by the individual 126 via graphical user interface on an external input device 114 either via wireless communication 113 or a wired connection 115.
[0048] In some embodiments, a closed-loop configuration of the systems and methods described herein, comprises a fully synchronized system, as shown in FIG. 9. In some embodiments, an electrode 902, comprising a sensor and/or stimulator electrode may detect an EMG, ENG, and/or pressure signal through circuitry 904 (e.g., analog to digital circuitry) and then may pass the detected signal to a classifier algorithm 906. Once the classifier algorithm 906 has classified the detected EMG, ENG, and/or pressure signal as an episode of pain, the classifier may enable an electric stimulation 908 to be delivered to the patient. As shown in FIG. 9, the electrical stimulation may be provided by the same electrode 902 that sensed the EMG and/or ENG signal initially.
[0049] In some embodiments, a closed-loop configuration of the device described herein may be configured to detect an episode of pain in an individual. In some embodiments, the methods and systems described here may supplement the patient’s effort to reduce pain with an electrical stimulation pattern via one or more stimulator electrodes 122 sufficient to reduce or prevent an episode of pain. In some embodiments, an individual’s effort may be measured with an EMG, ENG, pressure, acceleration, gyroscope, magnetometer, 3-D spatial, or any combination thereof signal at a threshold. In some embodiments, the threshold myoelectric signal may be detected by one or more sensors 120. In some embodiments, the adapted stimulation, comprises an electrical signal provided by the stimulator electrodes, described elsewhere herein, with parameters e.g., frequency, pulse width, and/or amplitude such that, alone or in combination with the detected individual’s effort and/or basal stimulation, may reduce prevent an episode of pain. In some embodiments the one or more parameters of the adapted stimulation may be determined on an individual subject basis and/or on a large-scale population of subjects with similar presentation. For example, for a given subject’s adapted stimulation, one or more parameters may be tuned and/or determined by whether such adapted stimulation reduces an episode of pain in real-time or after the episode of pain through the sensor or a user interface of the device, described elsewhere herein. In some embodiments, for a given subject’s adapted stimulation, one or more parameters may be tuned to values and/or parameters found to reduce or prevent pain in subjects with similar clinical presentation (e.g., age, type of pain, frequency of pain episode, other subject clinical meta data, etc.).
[9050] In some embodiments, the system and methods described herein comprises system and methods configured to provide an electrical stimulation to prevent an episode of pain based on a subject and/or patient’s purposeful muscle contraction and/or movement, as seen in FIG. 8. In some embodiments, the subject and/or patient 814 may, upon realizing that they may exhibit an episode of pain, induce movement and/or contraction of one or more muscles or muscle groups to trigger an EMG, ENG, pressure, acceleration, gyroscope, magnetometer, 3-D spatial, or any combination thereof signal 818. In some embodiments, the induced movement and/or contraction of one or more muscle groups may be amplified 808, classified (by a classifier) 806, passed through a control logic algorithm 804, and used as a trigger 820 to enable the flow of therapy and respective basal 802 and/or active 801, described elsewhere herein, stimulation pattern parameters through the stimulator 810 and neural interface 812 to prevent an episode of pain. In some embodiments, the classifier comprises a machine learning classifier. In some embodiments, the classifier comprises an intensity threshold classifier, described elsewhere herein. In some embodiments, the patient and/or subject 814 may manually 816 enable the delivery of electrical stimulation via a button on the patient controller module 156, described elsewhere herein.
[0051] In some embodiments, the detection threshold of the implantable pulse generator 118 (i.e., stimulator) may be modified and tuned via a graphical user interface on an external input device 114. The external input device 114 may be able to modify and tune the threshold of the implantable pulse generator 118 via a wireless communication 113 or a wired connection 115. In some embodiments, the implantable pulse generator threshold may be tuned via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via a wired communication 116 to the implantable pulse generator 118. In some embodiments, the implantable pulse generator threshold may be tuned via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via wireless communication 113 to the implantable pulse generator 118. In some embodiments, the implantable pulse generator threshold may be tuned via the individual on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via a wired communication 116 to the implantable pulse generator 118. In some embodiments, the implantable pulse generator threshold may be tuned via the individual on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via wireless communication 113 to the implantable pulse generator 118.
[6052] In some embodiments, the electrical stimulation pattern 124 provided via one or more stimulator electrodes 122 may be tuned and adjusted by the detected threshold level to supplement an individual’s effort to prevent an episode of pain. In some embodiments, the adjusted electrical stimulation pattern 124 may be determined by mapping a detectable physiological signal representing effort and a provided electrical stimulation pattern 124 by, piecewise linear mapping, linear mapping, sigmoidal mapping, or any variations thereof. The electric stimulation pattern 124 may be tuned by modifying or changing the electrical stimulation pattern parameters comprising frequency, pulse-width, and amplitude. In some embodiments, the electrical stimulation pattern parameters of the implantable pulse generator 118 may be modified and tuned via a graphical user interface on an external input device 114. The external input device 114 may be able to modify and tune the electrical stimulation pattern parameters of implantable pulse generator 118 via a wireless communication 113 or a wired connection 115. In some embodiments, the electrical stimulation pattern parameters of implantable pulse generator 118 may be tuned via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via a wired communication 116 to the implantable pulse generator 118. In some embodiments, the electrical stimulation pattern parameters of implantable pulse generator 118 may be tuned via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, a tablet, a computer, etc.) and transmitted via wireless communication 113 to the implantable pulse generator 118. In some embodiments, the electrical stimulation pattern parameters of implantable pulse generator 118 may be tuned by a machine learning model executed by the processor of the implantable pulse generator 118 based on input from the individual 126. In some embodiments, the machine learning model may be configured to determine a whether or not a subject is at risk of unwanted micturition and/or fecal defecation based on muscle EMG signals detected by the one or more sensors. In some embodiments, the machine learning model may be trained to determine the presence or lack thereof an individual’s effort, described elsewhere herein. For example, the machine learning model may be trained with one or more EMG signals characteristic of a subject’s muscle contractions in particular EMG signals that lead to pain.
(0053] In some embodiments, the electrical stimulation pattern parameters, as described elsewhere herein (e.g., frequency, amplitude, etc.), may be set or determined by a stimulation machine learning model. In some embodiments, the stimulation machine learning model comprises a Bayesian optimization model. In some embodiments, the stimulation machine learning model may be trained with stimulation patterns that users of the devices and systems, described elsewhere herein, indicate as inhibiting episode of pain for types and/or subtypes of pain. In some embodiments, the stimulation machine learning model may be trained with the patient’s type of pain. The stimulation machine learning algorithms may be trained in a cloud computing network and/or server in communication with the implantable and user-devices, described elsewhere herein, and redistributed or downloaded to one or more users and/or patients. In effect users and/or patients may update and/or download new updates to the software of the devices and systems described herein. This aspect of the invention described herein provides an unexpected result of a patient specific and optimized electrical stimulation signal that would otherwise not be achievable with a traditional stimulator.
[0054] One or more machine learning algorithms may be used to construct the machine learning model, such as support vector machines that deploy stepwise backwards parameter selection and/or graphical models, both of which may have advantages of inferring interactions between parameters. For example, machine learning algorithms or other statistical algorithms may be used such as alternating decision trees (ADTree), decision stumps, functional trees (FT), logistic model trees (LMT), logistic regression, random forests (rf), receiver operational characteristic curves (ROC), linear regression, extreme gradient boosting (xgb), classification and regression trees, support vector machines (SVM), generalized additive model using splines (e.g., gamSpline), glmnet, multivariate adaptive regression splint (earth), neural network, k-means clustering, or any machine learning algorithm or statistical algorithm known in the art. One or more algorithms may be used together to generate an ensemble method, wherein the ensemble method may be optimized using a machine learning ensemble meta-algorithm such as boosting (e.g., AdaBoost, LPBoost, TotalBoost, BrownBoost, MadaBoost, LogitBoost, etc.) to reduce bias and/or variance.
[6055] In some embodiments, the machine learning algorithm comprises a constrained machine learning algorithm configured to run on micro-processors. In some embodiments, the machine learning algorithm comprises a machine learning algorithm operating on within a TinyML framework. In some embodiments, the machine learning algorithm, described elsewhere herein may be trained offline. The offline training may be completed on a server, cloud, or other dedicated computing clusters. In some embodiments, the offline trained machine learning algorithm could then be downloaded, deployed, and/or imported into the device to iteratively improve upon the device and system performance in preventing or reducing pain of an individual.
[0056] One of ordinary skill would realize that such an off-line training structure is feasible and realized in related but different implementation. For example, such a machine learning architecture may be utilized in performing “wake up-word” text classification that are commonly seen in smartphone devices (e.g., “hey siri”, “okay google”, etc.). In some embodiments, the machine learning algorithms described herein may operate within a framework similar to the “wake up-words” speech machine learning classifier. In some embodiments, the machine learning algorithms described herein may operate on processing power and memory allocation determined to be sufficient for “wake up” speech machine learning classifiers.
[0057] In some embodiments, the software, described elsewhere herein, may be executed by a processor located on the implanted stimulator. In some embodiments, the software located on the implanted stimulator may utilize a TinyML constrained machine learning model to accommodate the processing and memory parameters of the implanted stimulator. In some embodiments, the software may be executed offline on a cloud-based computing and/or dedicated computing duster(s). In some embodiments, the offline processing workflow may include a high-speed (Bluetooth, Wi-Fi, medical implant communication systems, etc.) data transfer between the implanted stimulator and a local personal computing device (smartphone, tablet, laptop, etc.). The personal processing device may then communicate the implanted stimulator data to a one or more cloud and/or computer clusters that will then send back a resulting output, command, and/or notification to the device. In some embodiments, the command and/or notification comprises a warning, alert, initiation of electrical stimulation, or any combination thereof. In some embodiments, the command comprises the output of a machine learning classifier configured to determine a threshold intensity of EMG and/or ENG signals indicative of an episode of pain.
[0058] The machine learning models may be trained on one or more datasets. In some embodiments, the one or more datasets comprises data generated by a user and/or subject, or data generated by a population or segment thereof. In some embodiments, the data generated by subject and/or the data generated by a population comprises effort signals, excitation signals, that indicated an episode of pain, and prevented an episode of pain, respectively. In some embodiments, the devices, systems, and corresponding methods described herein, may record user data and/or input of the user when interacting with the systems and devices described elsewhere herein. In some embodiments, the data comprises user labeled EMG, ENG, accelerometer, gyroscope, or any combination thereof sensors, as described elsewhere herein, that lead to an episode of pain. In some embodiments, these signals may be obtained from the device 1302, and used in characterizing 1304 and training a machine learning classifier 1306, as seen in FIG. 13. In some embodiments, the trained machine learning classifiers trained on or more datasets may then be downloaded to each patient’s device 1308 to further improve the machine learning classifier’s accuracy. In some embodiments, the machine learning models may be configured to sense subject effort and/or providing sufficient excitation based on e.g., parameters of frequency, amplitude, and/or pulse-width as described elsewhere herein. In some embodiments, the datasets of one or more individuals may be pooled together as a training dataset where the subjects show characteristics of similarity between clinical presentation and parameters of excitatory/sensory input. In some embodiments, clinical presentation comprises clinical pain type, subject clinical meta data, e.g., gender, age, past medical history, current medications taken, past surgical intervention, etc. In some embodiments, a pooled training datasets may be utilized for an individual during the initial period of training a device implanted into a subject. (0059] In some embodiments, the one or more machine learning models, described elsewhere herein, may be trained on raw and/or processed signals measured by the devices, sensors, and systems, described elsewhere herein. In some embodiments, the processed signals comprises original raw signals that have been filtered to optimize the signal-to-noise ratio of the raw signal. In some embodiments, the filter comprises a high-pass, low-pass, band-pass, notch, or any combination thereof filters. In some embodiments, the one or more machine learning models may be trained on user feedback regarding prior excitation signal parameters and whether or not such excitation signal parameters prevented an episode of pain.

(0063) In some embodiments, the amplified signal is passed to a filter 1004. In some embodiments, the filter comprises a low-pass, high-pass, band-pass, notch, or any combination thereof filter.
[0064] In some embodiments, the filter may be configured to filter the frequency band of about 1 Hz to about 70 Hz.

In some embodiments, the filter may be configured to filter the frequency band of about 1 Hz, about 5 Hz, about 10 Hz, about 15 Hz, about 20 Hz, about 25 Hz, about 40 Hz, about 50 Hz, about 60 Hz, or about 70 Hz.

[0065] After passing the signal through the filter, the systems and methods described herein, may rectify 1006 the filtered signal. In the process of rectifying the signal, as understood by one of ordinary skill in the art, the signal will convert the alternating current detected signal to a direct current signal. The rectified signal may be additionally filtered with a low pass filter 1007 that may smooth the rectified signal. The signal may be subjected to a threshold detector 1008, where the threshold detector determines the onset of an episode of pain from a threshold intensity value of the rectified and smooth processed signals 1000 of EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signals, or any combination thereof. If an episode of pain is determined by the threshold detector 1008, the system may enable the delivery of electrical stimulation 1010, as described elsewhere herein.
[0066] In some embodiments, training may be supervised training. In some embodiments, training may be unsupervised training. In some embodiments, the data set may be a retrospective data set. In some embodiments, the data set may be prospectively developed dataset, and the machine learning model may be iteratively improved over time. £00§7] In some embodiments, the disclosure provided herein comprises a method to train a machine learning model with a data set that comprises sensed signal profiles and excitation signals that have and have not prevented episodes of pain. The method comprises the steps of: preprocessing, training, and predicting.
The method may extract training data from a database, or intake new data, described elsewhere herein. The preprocessing step may apply one or more transformations to standardize the training data or new data for the training step or the prediction step. The preprocessed training data may be passed to the training step, which may construct a machine learning model based on training data. The training step may further comprise a validation step, configured to validate the trained machine learning model using any appropriate validation algorithm (e.g., Stratified K-fold cross-validation). In some embodiments, the k- fold cross-validation comprises at least 1-fold, 2, folds, 3 folds, 4 folds, 5 folds, 6 folds, 7 folds, 8 folds, 9 folds, or 10 folds. In some embodiments, the k-fold cross-validation comprises up to 1-fold, 2 folds, 3 folds, 4 folds, 5 folds, 6 folds, 7 folds, 8 folds, 9 folds, or 10 folds.
[0069] The preprocessing step may apply one or more transformations to the training data to clean and normalize the data. The preprocessing step may be configured to discard parameters which contain spurious data or contain very few observations. The preprocessing module can be further configured to standardize the encoding of parameter values. The preprocessing step may recognize the encoding variation for the same value and standardize the dataset to have a uniform encoding for a given parameter value. The processing step may thus reduce irregularities in the input data for the training and prediction steps, thereby improving the robustness of the training and prediction steps.
[0070] The training step may utilize a machine learning algorithm or other algorithm to construct and train a machine learning model to be used in the association of an excitation stimulation, sensed signal profile, and the presence or lack thereof an episode of pain. A machine learning model may be constructed to capture, based on the training data, the statistical relationship, if any, between excitation stimulation parameters, sensed signal profiles, and the presence or lack thereof an episode of pain.
[0071] The machine learning algorithm may have an accuracy greater than about 60%, 70%, 80%, 85%, 90%, 95%, or 99%. The machine learning algorithm may have a positive predictive value greater than about 60%, 70%, 75%, 80%, 85%, 90%, 95%, or 99%. The machine learning algorithm may have a negative predictive value greater than about 60%, 70%, 80%, 90%, 95%, or 99%.
[0072] Machine learning data analysis, machine learning model training, or any combination thereof may be performed using one or more of many programming languages and platforms known in the art, such as R, Weka, Python, and/or MATLAB, for example.
[0073] The use of such closed-loop bioelectronic systems may potentially provide improved electrical stimulation devices to prevent or reduce pain of the individual. In some embodiments, the use of such closed-loop bioelectronic systems may provide a more precise approach to prevent or reduce or treat pain of the individual. In some embodiments, individuals having the implanted device may provide feedback to the parameters provided positive outcomes, negative outcomes, or neutral outcomes. In some embodiments, positive outcomes comprise preventing an episode of pain. In some embodiments, negative outcomes comprise not preventing an episode of pain, producing pain, or any combination thereof. In some embodiments, neutral outcomes comprise not preventing an episode of pain, not producing pain, or any combination thereof . In some embodiments, the positive outcomes, negative outcomes, neutral outcomes, sensor data, or any combination thereof from a plurality of individuals having the implanted device may be used in tuning algorithms to suggest changes to sensor thresholds and electrical stimulation patterns 124.
[0074] In some cases, the feedback and/or pain outcomes of the individual may be provided by a score or outcome of a survey, test, and/or questionnaire. The survey, test, and/or questionnaire may comprise the numeric pain rating scale (NPRS), patient global impression of change (PGIC), Cleveland Clinic Constipation and Incontinence Scores (CCCS and CCIS), International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF-UI), Patient Global Impression of Improvement Scale (PGI-I), Female Sexual Function Index (FSFI), McGill Pain Questionnaire (MPQ), Visual Analogue Scale (VAS), or any combination thereof.

Method of Treating Pain
[0138] FIG. 6A illustrates a workflow of a method 216 of reducing pain of an individual. The method comprises the steps of (a) implanting a sensor and a stimulator electrode within a body (e.g., pelvic area) of the individual 218; (b) sensing with the implanted sensor a parameter associated with an episode of pain of the individual 220; and (c) providing an adapted electrical stimulation with the implanted stimulator electrode that reduces pain of the individual 222. The methods described herein prevent or reduce pain associated with an episode of pain of the individual by providing an adapted electrical stimulation with a stimulator electrode implanted in the individual. In some embodiments, the sensor is implanted in the body of the individual. In some embodiments the sensor is implanted in the pelvic area of the individual.
[0139] In some embodiments, the method comprises a step of providing a base electrical stimulation. In some embodiments, the base electrical stimulation is provided at a lower intensity level than the adapted electrical stimulation. In some embodiments, the base electrical stimulation is provided at a different intensity level than the adapted electrical stimulation. In some embodiments, the base electrical stimulation provided reduces pain associated with constant or near-constant pain associated with chronic pelvic pain. In some embodiments, the intensity or duration of the adapted electrical stimulation provided varies according to the parameter that is sensed. In some embodiments, the parameter indicates that at least one of the amplitude, frequency, or intensity of the basal electrical stimulation must be increased to prevent or reduce pain of the individual. In some embodiments, the adapted electrical stimulation boosts (i.e., increases at least one of the amplitude, frequency, or intensity) of the base electrical stimulation. In some embodiments, the time period between sensing a parameter 224 and providing an electrical stimulation 226 may be described as a response time 228, as shown in FIG. 6B. In some embodiments, the stimulation may be provided for a duration of stimulation 227.

[0142] FIGS. 12A-12B illustrate a workflow of a method 1200 for preventing an episode of pain in an individual. The method comprises the steps of (a) implanting a sensor and stimulator electrode within a body of an individual 1202; (b) sensing a parameter associated with pain from the individual, where the response is individual-induced stimulus 1204; and (c) providing an electric stimulation with the stimulator electrode to reduce or prevent the episode of pain 1206. In some embodiments, the user induced stimulus may be intended to prevent an episode of pain. As shown graphically in FIG. 12B, a detected EMG signal 1208 may be analyzed by a classifier 1210, described elsewhere herein, to determine when the EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signals or any combination thereof signals have crossed a pre-determined threshold, described elsewhere herein. Once the classifier 1210 has determined that the signal 1208 does represent an episode of pain, the processor, described elsewhere herein, may enable stimulation 1212 to prevent the episode of pain from occurring. In some embodiments, stimulation 1212 comprises an extension of stimulation 1211 that may extend beyond the time the classifier 1210 determines there to be an episode of pain. In some embodiments the extension of stimulation 1211 comprises a duration of time equal to the duration the subject continues to purposefully or with intent produce a muscle contraction.
[0143] In some embodiments, the extension of stimulation comprises about 1 s to about 30 s. In some embodiments the extension of stimulation comprises about 1 s to about 3 s, about 1 s to about 5 s, about 1 s to about 8 s, about 1 s to about 10 s, about 1 s to about 12 s, about 1 s to about 15 s, about 1 s to about 18 s, about 1 s to about 20 s, about 1 s to about 22 s, about 1 s to about 24 s, about 1 s to about 30 s, about 3 s to about 5 s, about 3 s to about 8 s, about 3 s to about 10 s, about 3 s to about 12 s, about 3 s to about 15 s, about 3 s to about 18 s, about 3 s to about 20 s, about 3 s to about 22 s, about 3 s to about 24 s, about 3 s to about 30 s, about 5 s to about 8 s, about 5 s to about 10 s, about 5 s to about 12 s, about 5 s to about 15 s, about 5 s to about 18 s, about 5 s to about 20 s, about 5 s to about 22 s, about 5 s to about 24 s, about 5 s to about 30 s, about 8 s to about 10 s, about 8 s to about 12 s, about 8 s to about 15 s, about 8 s to about 18 s, about 8 s to about 20 s, about 8 s to about 22 s, about 8 s to about 24 s, about 8 s to about 30 s, about 10 s to about 12 s, about 10 s to about 15 s, about 10 s to about 18 s, about 10 s to about 20 s, about 10 s to about 22 s, about 10 s to about 24 s, about 10 s to about 30 s, about 12 s to about 15 s, about 12 s to about 18 s, about 12 s to about 20 s, about 12 s to about 22 s, about 12 s to about 24 s, about 12 s to about 30 s, about 15 s to about 18 s, about 15 s to about 20 s, about 15 s to about 22 s, about 15 s to about 24 s, about 15 s to about 30 s, about 18 s to about 20 s, about 18 s to about 22 s, about 18 s to about 24 s, about 18 s to about 30 s, about 20 s to about 22 s, about 20 s to about 24 s, about 20 s to about 30 s, about 22 s to about 24 s, about 22 s to about 30 s, or about 24 s to about 30 s.
In some embodiments the extension of stimulation 1211 comprises about 1 s, about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, about 24 s, or about 30 s. In some embodiments the extension of stimulation 1211 comprises at least about 1 s, about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, or about 24 s. In some embodiments the extension of stimulation 1211 comprises at most about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, about 24 s, or about 30 s.
[0144] In some embodiments, there may be a delay 1209 between the onset of the episode of pain in the raw EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor, or any combination thereof signal data, and the onset of the electrical stimulation. Upon training the classifier 1210 on sufficiently large and varied datasets, such delay may be minimized further improving the device performance in prevent episodes of pain. In some embodiments, sensing comprises determining a global positioning system (GPS) location of the individual that in combination with the parameter associated with the response from the individual is used to prevent the episode of pain.
Ambulatory Assessments After Implantation
[0145] In some embodiments, various ambulatory assessments may be taken to determine the effectiveness of the implantation procedure. In some embodiments, the implanted IPG permits telemetric downloading of data (inputs, outputs, and event classification). In some embodiments, the participant may be in an awake ambulatory setting and a series of resting and provoked electrophysiological data may be recorded. In some embodiments, at treatment initiation (24-48 hours post-implant) sensory and motor responses may be determined from the different sensors on the implanted leads. In some embodiments, based upon the responses, the electrodes with the most adequate response may be selected to initiate treatment.
[0145] In some embodiments, the patients may be subjected to different physiological events to program the IPG. In some embodiments, these events comprise coughing, Valsalva maneuvers, picking up a 5kg weight, or any combination thereof. In some embodiments, pelvic floor EMG may be measured with a transvaginal and/or anal probe. In some embodiments urethral pressures may be measured. In some embodiments, 1 hour continuous ‘resting’ recording of inputs and outputs (downloaded by telemetry) may be taken. In some embodiments, recording during controlled participant provoked events, such as coughing, Valsalva, lifting 5 Kg weight, may be obtained. In some embodiments, recording during pelvic floor surface EMG (from transvaginal probe: women only) to correlate inputs from lead vs. surface EMG may be obtained. In some embodiments, patient tolerances of basal stimulation ramping, and actuation parameters may be obtained.

It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.
EXAMPLES
Example 1 : A system lacking a closed-loop configuration
[0163] FIG. 1 shows an exemplary embodiment of an open-loop bioelectronic system comprising an implantable pulse generator. The system delivers a predefined stimulation protocol and does not receive input from the subject, resulting in inadequate pain management. Example 2: Reducing Pain of Episodes Associated with Inflammation
[0164] The systems, methods, and devices, described herein, reduce the pain of conditions associated with peripheral drive to pain due to clinical or sub-clinical inflammation (e.g. interstitial cystitis, chronic prostatitis, and radiation vaginitis) by stimulating afferents for gating of peripheral nociception (e.g., positive or negative), anodal block, or any combination thereof. In case of interstitial cystitis, pain increases as the bladder increasingly fills, which is often accompanied with an increase in pelvic floor muscle tone. Thus, an episode of pain can be detected using a sensor configured to detect at least one of an EMG, ENG, or pressure signal. An episode of pain can also be detected using a sensor configured to detect a signal associated with a patient actuated response (e.g., the patient taps a button to indicate onset of an episode of pain, transmitting the signal to a processor or a sensor electrically coupled to the processor).
[0165] In some embodiments, a basal stimulation is provided to reduce pain associated with inflammation with adapted stimulations being provided after detecting and/or receiving a parameter associated with an episode of exacerbating pain (e.g., bladder filling beyond a threshold). In some embodiments, receiving a parameter associated with increased pelvic floor muscle tone changes the stimulation provided by the implanted electrode from one anatomical site (e.g., pudendal, sacral, and/or pelvic plexus) to both anatomical sites simultaneously (e.g., pudendal, sacral, and/or pelvic plexus). In some embodiments, the stimulation returns to the initial basal stimulation after bladder emptying ends, which may be initiated by a patient response or by pelvic floor sensing (e.g., EMG, ENG) because emptying the bladder is usually accompanied by relaxation of the pelvic floor muscles.
Example 3: Preventing Pain of Episodes Associated with Nerve Compression
[0166] The systems, methods, and devices, described herein, reduce the pain of conditions associated, at least in part, with compression of nerve endings due to striated muscle spasm (e.g., pelvic floor myalgia, coccygodynia, urethral and penile pain syndromes) and/or anatomical compression (e.g., pudendal neuralgia) by modulating motor nerve activity, anodal block, or any combination thereof. In conditions associated with nerve compression, there may be an impact of bladder filling state and/or body posture (e.g., sitting vs lying) that leads to an episode of exacerbating pain. In some embodiments, a GPS signal is used to indicate or predict an episode of exacerbating pain, like when an individual enters a sleeping room or bathroom (i.e., predict that the individual will soon change posture). In some embodiments, a time and/or time-of-day signal are used to predict or indicate the episode of exacerbating pain. In some embodiments, conditions associated with nerve compression are detected by measuring nerve activity (e.g., by detecting an ENG signal of a sacral or pudendal nerve) and/or measuring activity of the muscle surrounding the compressed nerve (e.g., by detecting an EMG signal of the pelvic floor).
Example 4: Preventing and Reducing Pain of Episodes Associated with Dysrequlated Visceral Smooth Muscle Activity
[9167] The systems, methods, and devices, described herein, reduce the pain of conditions mainly associated with dysregulated visceral smooth muscle activity (e.g. painful bladder syndrome, proctalgia fugax) by modulating motor activity to affect organ smooth muscle activity, afferent gate control, anodal block, or any combination thereof.
Example 6: Preventing and Reducing Pain of Episodes Characterized as Neuropathic Pain
[9168] The systems, methods, and devices, described herein, reduce the pain of conditions associated, at least in part, with conditions mainly characterized as neuropathic pain (e.g. vulvodynia, vestibulodynia, phantom rectum syndrome, proctalgia fugax) by afferent gating of spinal activity.
Example 5: EMG Measurement Reproducibility
[9169] Using the systems, methods, and devices, described herein, patient EMG signals were measured and processed as patients performed muscle contractions, coughing, and Valsalva maneuvers, as can be seen in FIGS. 11A-11E. For each patient, raw EMG data 1102 was recorded and amplified, as described elsewhere herein. Subsequently, the raw EMG data was filtered 1106, rectified, and smoothed 1104. [917(1] From the data shown in FIGS. 11A-11C, where a single patient iteratively performed the same sequence of muscle contractions three times, a distinct group of three signals may be observed in the temporal EMG data. Such a finding supports the reproducibility of the sensors of the devices and systems described herein and the potential ability of a trained classifier to distinguish EMG signals temporally. Similarly, data for a different patient shown in FIGS. 11 D-11 E shows similar results as the patient in FIGS. 11A-11C.
Example 6: Treating Unilateral Pain
[9171] The systems, methods, and/or devices, described elsewhere herein, may be used to treat an individual’s unilateral or predominately unilateral pain (e.g., left sided pelvic pudendal neuralgia). To treat the unilateral or predominantly unilateral pain one or more electrode leads (e.g., one or more stimulation or sensing electrodes), described elsewhere herein, are implanted at or adjacent to the left pudendal nerve. Alternatively, a first electrode of the one or more electrodes is implanted on the left pudendal nerve, and a second electrode of the one or more electrodes is implanted at different left sided nerve target such as the sacral nerve or pelvic autonomic plexus. A pulse generator is implanted in the individual and electrically coupled to the one or more electrode leads. The implanted device is then configured by medical care personnel (e.g., an attending physician, nurse, or operating theater room medical support staff) based at least on the individual’s known unilateral pain.
[0172] After a period of time subsequent to implantation of the one or more electrodes and stimulator, the individual is provided one or more surveys and/or questionaries, e.g., numeric pain rating scale (NPRS), described elsewhere herein, to determine the clinical outcome of the implanted device and improvements to the individual’s unilateral pain. A positive and significant clinical outcome of reducing unilateral pain will be reflected in the individual obtaining a NPRS score and/or a VAS rating after receiving treatment that is less than a NPRS score and/or a VAS rating obtained by the individual prior to receiving the implant and pain treatment.
Example 7: Treating Bilateral Pain
[9173] The systems, methods, and/or devices, described elsewhere herein, may be used to treat an individual’s bilateral or predominantly bilateral pain. To treat the bilateral or predominantly bilateral pain one or more electrode leads (e.g., one or more stimulation or sensing electrodes), described elsewhere herein, are implanted on the left and right pudendal nerves, both sacral nerves, nerves of the pelvic plexus, or any combination thereof. A pulse generator is implanted in the individual and electrically coupled to the one or more electrode leads. The implanted device is then configured by medical care personnel (e.g., an attending physician, nurse, or operating theater room medical support staff) based at least on the individual’s known bilateral pain.
[9174] After a period of time subsequent to implantation of the one or more electrodes and stimulator, the individual is provided one or more surveys and/or questionaries, e.g., numeric pain rating scale (NPRS), described elsewhere herein, to determine the clinical outcome of the implanted device and improvements to the individual’s bilateral pain. A positive and significant clinical outcome of reducing bilateral pain will be reflected in the individual obtaining a NPRS score and/or a VAS rating after receiving treatment that is less than a NPRS score and/or a VAS rating obtained by the individual prior to receiving the implant and pain treatment.
Example 8: Treating Bladder Pain Syndrome
[9175] The systems, methods, and/or devices, described elsewhere herein, may be used to treat an individual’s bladder pain syndrome. To treat bladder pain syndrome for an individual exhibiting primarily urinary incontinence and bladder pain, one or more electrode leads (e.g., one or more stimulation or sensing electrodes), described elsewhere herein, are implanted bilaterally on pudendal nerves to reduce pain and stabilize bladder functions. To treat bladder pain of an individual who has bladder emptying problems, the one or more electrode leads, are implanted at or adjacent a pudendal nerve and a pelvic autonomic nerve to reduce pain and facilitate bladder emptying. A pulse generator is implanted in the individual and electrically coupled to the one or more electrode leads in either case as described above. The implanted device is then configured by medical care personnel (e.g., an attending physician, nurse, or operating theater room medical support staff) based at least on the individual’s bladder pain syndrome.
[0176] After a period of time subsequent to implantation of the one or more electrodes and stimulator, the individual is provided one or more surveys and/or questionaries, e.g., numeric pain rating scale (NPRS), described elsewhere herein, to determine the clinical outcome of the implanted device and improvements to the individual’s bladder pain. A positive and significant clinical outcome of reducing bladder pain will be reflected in the individual obtaining a NPRS score and/or a VAS rating after receiving treatment that is less than a NPRS score and/or a VAS rating obtained by the individual prior to receiving the implant and pain treatment.
Example 9: Treating Chronic Anal and/or Perineal Pain
[0177] The systems, methods, and/or devices, described elsewhere herein, may be used to treat an individual’s chronic anal and/or perineal pain. Such subjects presenting with chronic anal and/or perineal pain may have pain associated with or without defecatory symptoms including symptoms of obstructive defecation and/or fecal incontinence. To an individual’s chronic anal and/or perineal pain, one or more electrode leads (e.g., one or more stimulation or sensing electrodes), described elsewhere herein, are implanted bilaterally on pudendal and/or pelvic autonomic nerves to reduce pain and facilitate rectal emptying. A pulse generator is implanted in the individual and electrically coupled to the one or more electrode leads in either case as described above. The implanted device is then configured by medical care personnel (e.g., an attending physician, nurse, or operating theater room medical support staff) based at least on the individual’s chronic anal and perineal pain.
[0178] After a period of time subsequent to implantation of the one or more electrodes and stimulator, the individual is provided one or more surveys and/or questionaries, e.g., numeric pain rating scale (NPRS), and/or a VAS rating, described elsewhere herein, to determine the clinical outcome of the implanted device and improvements to the individual’s chronic anal and/or perineal pain. A positive and significant clinical outcome of reducing chronic anal and perineal pain will be reflected in the individual obtaining a NPRS score and/or a VAS rating after receiving treatment that is less than a NPRS score and/or a VAS rating obtained by the individual prior to receiving the implant and pain treatment. Other defecatory symptoms may be measured using other questionnaire-based scoring instruments including: Cleveland Clinic Constipation and Incontinence scores, St Marks Incontinence Score; the Patient Assessment of Constipation-Symptoms (PAC-SYM) questionnaire; fecal incontinence severity index (FISI).
