Definitions

  • the present invention relates to a device and a method for training pelvic floor muscles of a user.
  • the device comprises a sensor for sensing an activity of the pelvic floor muscles.
  • an app on a remote electronic device supports the training according to the method.
  • Further aspects of the invention comprise a system and a kit for training the pelvic floor muscles.
  • the pelvic floor is composed of muscle fibres, such as the levator ani, the coccygeus muscle, and associated connective tissue, which span the area underneath the pelvis.
  • the pelvic floor is important in providing support for pelvic organs, e.g. the bladder, intestines, and the uterus (in women), as well as for the maintenance of continence. However, it can be damaged in pregnancy and childbirth or through pelvic surgery.
  • the pelvic floor muscles may be trained by specific exercises, also known as Kegel exercises.
  • various devices exist, of which some are only applicable by women.
  • compliance with a pelvic floor training is often poor, unless the user gets direct feedback, and/or is supervised by a third party, such as a medical doctor.
  • some training devices comprise sensors for sensing an activity of the pelvic floor muscles, a disadvantage being that the sensed quantity does often not only indicate an activity of the pelvic floor muscles, but additionally depends on an activity of other muscle groups, such as gluteal and/or abdominal muscles.
  • WO 2011/077868 relates to a swing-type exercising device comprising a seat on which the user can be seated, a motion mechanism for allowing the seat to perform a swing motion, a pelvic floor muscle measuring device for measuring a muscle activity of the user's pelvic floor muscle, and an informing device for informing the user of measurement information obtained by the pelvic floor muscle measuring device.
  • US 2015/0141881 relates to a seating apparatus for diagnosis and treatment of diagnosing and curing urinary incontinence, erectile dysfunction and defecation disorders by measuring contraction pressure and contraction duration of pelvic floor muscles, muscles of perineum and anal sphincters of a user, who puts on cloth while seated, simultaneously with curing symptoms of urinary incontinence, erectile dysfunction and defecation disorders throughout biofeedback exercise and training.
  • the problem to be solved by the present invention is to provide a portable device and a method for training pelvic floor muscles of a user, which overcome the disadvantages and limitations of the existing methods and devices, or which represent an alternative to the existing methods and devices.
  • the problem is solved by a portable device for training pelvic floor muscles according to claim 1.
  • the portable device comprising a rigid housing for a user to sit on comprising a ridge with an opening facing the pelvic floor muscles of the user sitting on it, a beam arranged in the housing, being flush with or protruding from or facing the opening in the ridge, adapted to couple to an activity of the pelvic floor muscles of the user, and a sensor for sensing a movement of and/or a force exerted on the beam.
  • the device is a portable device, preferably of dimensions to be carried by person without effort, e.g. in a toilet bag. Accordingly, it may be used at home or during travel. In this context, it can be regarded as portable or mobile health care device. Generally, the device can be used by men, women, or children.
  • the housing may have a triangular cross-section, or the ridge may protrude, a shape of the housing making it convenient for the user to sit on it.
  • the opening in the ridge allows to sense an activity of the pelvic floor muscles which is transferred to the sensor via a beam.
  • the housing is rigid, e.g. preferably made from one or more of metal, such as aluminium, or hard plastic, such that it does not significantly deform when a user sits on it.
  • a bottom plate of the housing which may include cross beams or other stiffening means, as well as supports for other elements arranged in the housing, can be made from aluminium, while other portions of the housing, such as the ridge or the entire casing arranged on the bottom plate preferably is made from hard plastic.
  • the beam is also rigid, e.g. made of metal, such as aluminium, or from hard plastic, in order to transfer a movement and/or a force to the sensor in an optimum way.
  • the device comprises communication means adapted to transmit a signal of the sensor to a remote electronic device, in particular wherein the communication means is a Bluetooth transmitter for connecting to a mobile device, and a power supply, in particular a battery, for supplying the sensor and the communication means with power.
  • the remote electronic device may e.g. be a mobile phone or a computer, configured to process and output the signal.
  • the device is mobile and light-weight.
  • the power supply and/or the communication means may be connected to the remote electronic device through a cable.
  • the device comprises guiding means, in particular at least one guiding pin, to restrict movements of the beam to a direction perpendicular to the opening in the ridge, and an elastic element, in particular a pressure spring, between the housing and the beam, providing a restoring force for movements of the beam.
  • the guiding means may comprise rails or a suspension for the beam
  • the elastic element may comprise a piece of rubber.
  • the guiding means and the arrangement of the beam allow to sense a certain muscular activity, i.e. a contraction and/or relaxation of the pelvic floor muscles, while suppressing the influence of other muscular activities in the sensed signal.
  • the elastic element ensures that the beam is coupled to and follows the movements of the pelvic floor muscles, not only during contraction, but also during relaxation.
  • the exact position of the elastic element between the housing and the beam is irrelevant for this purpose; in an embodiment, the elastic element may be positioned between a bottom plate of the housing and the beam; in a different embodiment, it may be positioned between the ridge and the beam.
  • the elastic element may be a spring, such as a leaf spring, for executing a spring force on the beam in the vertical direction, i.e. the direction perpendicular to the opening in the ridge.
  • the spring may be shaped such that at the same time it prevents a lateral deflection of the beam.
  • the spring may at the same time serve as a guiding means for the beam, which spring preferably is mounted to the bottom plate, and preferably is embodied as at least a three-point construction: While the spring is mounted to the bottom plate or other components of the housing in two points, the third point is coupled to the beam.
  • the beam comprises one or more shoulders at its bottom end facing the sensor. The spring in turn preferably acts on the shoulder/s and thereby presses the beam towards the sensor.
  • a mechanical protection element e.g. comprising one or more fins
  • the one or more fins are mounted to the bottom plate.
  • the beam preferably is arranged between the two of those fins.
  • the fins preferably are made from the same rigid material as the bottom plate and may be fixed to the bottom plate.
  • the protection element protects the beam from a lateral displacement in response to a lateral impact onto the ridge or the housing. Such lateral impact may in one example be evoked by a user sitting on the device.
  • the sensor sensing a force exerted on the beam comprises at least one load cell, where load cell denotes any kind of force sensor such as a strain gauge load cell, a piezoelectric load cell, a hydraulic load cell or a pneumatic load cell, in particular at least one strain gauge, in particular the sensor comprises two or more strain gauges arranged in a Wheatstone bridge configuration.
  • the sensor may also comprise a pressure sensor.
  • the load cell, in particular the at least one strain gauge allows to precisely determine the force exerted on the beam. For that purpose, in particular the change in resistance of the at least one strain gauge is measured, e.g. in a Wheatstone bridge configuration, which yields precise resistance measurements.
  • the sensor is initially calibrated with a known force after assembly of the device. In an embodiment, the beam acts on two load cells, and the signal of both load cells is added up.
  • the device comprises a cap covering the opening in the ridge, which cap is preferably made from silicone.
  • the cap makes sitting on the device for the user more convenient than an opening with a bare beam. Also, the cap protects the device from the ingress of dust and water. Thus, usability and cleanability of the device are improved.
  • the cap comprises or is made from an elastic material, e.g. a thermoplastic polymer, and preferably from a material softer than the material of the housing.
  • the cap comprises or is made from silicone.
  • the cap may completely seal the opening.
  • the cap is made integral with the ridge, or even with a casing of the housing, or, in a different embodiment is made integral with a coating of the ridge or the housing.
  • the cap and the ridge or the coating preferably represent one piece, i.e. form an integral element, however, possibly of different materials.
  • the cap serves or co-serves as guiding means for restricting movements of the beam to one dimension only, i.e. preferably to the dimension orthogonal to the opening in the ridge.
  • the cap preferably is one piece together with at least the ridge of the housing.
  • the cap and the beam are mechanically coupled.
  • a top end of the beam may include a notch into which a bar of the cap may reach, or vice versa.
  • the cap and the beam, and specifically the bar of the cap and the notch of the beam are arranged in a press fit.
  • the housing of the device has an extension 1 in longitudinal direction which represents its largest dimension, a width w and a height h including the ridge, in particular wherein 1 ⁇ 20 cm, and/or in particular wherein w ⁇ 8 cm, and/or in particular wherein h ⁇ 4 cm.
  • the choice of 1, w and h, as well as the shape of the housing contribute to the convenience of the user sitting on the device. For this reason, the device may neither be too high, nor too wide, i.e. the width w should not be larger than the distance between the user's seating bones. Considerations of sitting convenience do not pose limits onto the extension 1; however, 1 may not be too large for reasons of easy portability.
  • the longitudinal extension 1, the width w and the height h may also be larger than the limits given above. This may e.g. be the case when the housing has a width w greater than the distance between the user's seating bones, so that an entire weight of the user is put on the housing.
  • the height h and the width w of the housing vary along the longitudinal direction for convenience of the user sitting on it, and letting the user choose a seating position with suitable pressure on the pelvic floor by varying the seating position in longitudinal direction.
  • the variation in height h along the longitudinal direction may be such that it triggers an upright sitting posture of the user. Tangible numbers for the dimensions of an embodiment of the device are given further below.
  • the opening of the device with the above-mentioned dimensions is elongated in longitudinal direction and aligned with the ridge.
  • the longitudinal extension of the opening is in the range of 5 cm to 20 cm, preferably 11.7 cm, and its width is in the range of 0.5 cm to 2 cm, preferably 1.1 cm.
  • the dimensions and the location of the opening are chosen such that the beam optimally couples to movements of the pelvic floor muscles without picking up an activity of other muscle groups. For this reason, it is sensible that in a preferred embodiment, the opening is located centrally and follows the ridge.
  • a kit for training pelvic floor muscles comprises a device according to any of the embodiments described above, and a pad for placing the device on.
  • the pad is preferably made from a rigid material, such as metal or hard plastic.
  • the pad ensures a good and even coupling of the device to a base below, at the same time reducing a seat height of the device, and making sitting on the device more convenient for the user.
  • Such kit may be offered to the user as a device and a pad packaged together.
  • the pad includes a recess for receiving the device which recess is not a through hole but has a bottom instead. By this means, the device is arranged slightly lowered in comparison with its arrangement on a recess-less pad.
  • the recess has a height between 0.8 mm and 1 mm, preferably of 0,9 mm.
  • a kit including a device according to one of the preceding embodiments, and a bag for carrying the device.
  • a pad as introduced above may accompany the kit, and the bag may be suited for taking the device and the pad.
  • Another aspect of the invention concerns a method for supporting a training of pelvic floor muscles of a user, comprising receiving data indicative of an activity of the pelvic floor muscles, determining calibration values, in particular in response to a maximum contraction of the pelvic floor muscles and an idle state, processing the received data, and outputting the processed data, in particular in a visual and/or acoustic and/or haptic manner.
  • the received data according to the method is supplied by a device as described above, and more specifically by the sensor of the device.
  • the method is performed in automated fashion, e.g. in an app or a computer program.
  • a method does only reasonably support the training, if it is applied by the user in the first place.
  • the method is preferably designed to motivate the user to train.
  • a training of 5 min per day according to the method leads to an appreciable enhancement of the pelvic floor muscle performance, thereby decreasing pelvic problems, in particular after childbirth or surgery, reducing incontinence, and improving satisfaction in the user's sexual life.
  • An embodiment of the method makes use of the data indicative of an activity of the pelvic floor muscles sensed by the sensor of the device. Determining calibration values is important to account for a user's anatomy and the position of the device relative to the pelvic floor muscles and the buttocks of the user. Preferably the calibration values are taken to be the maximum value x 2 of the sensed signal reached by a wilful contraction of the pelvic floor muscles, and the minimum value x 1 of the sensed signal reached by the user sitting on the device without wilful contraction of the pelvic floor muscles, i.e. the idle state.
  • Embodiments of the processing of received data are described below. The output of the processed data may be presented in numerous different ways.
  • the appearance of the output strongly affects the motivation of the user for training, which shows the importance of an elaborate output comprising visual and/or acoustic and/or haptic feedback to the user.
  • Embodiments of the method with visual output are detailed below.
  • As an acoustic output it is envisaged to translate the processed data to a tone pitch.
  • a sound is played indicating success when the contraction of the pelvic floor muscles reaches a certain level.
  • the processed data is translated into vibrations, e.g. of the remote electronic device, in yet another embodiment.
  • the step of processing the received data comprises normalising the received data with the calibration values, deriving data indicative of a quantity and/or a dynamics of the contraction of the pelvic floor muscles from the normalised data, and using the derived data in a software representing tasks for the training.
  • Normalising the received data with the calibration values makes the data between different users and different training sessions comparable, and allows for a user adaptation and for a control of the training tasks with the processed data.
  • Data indicative of a quantity of the contraction characterises the static behaviour of the pelvic floor muscles
  • data indicative of a dynamics of the contraction describes the change of contraction/relaxation over time, e.g. the speed.
  • deriving such data may comprise signal processing, such as linearising a response function of the sensor, and/or translating the electrical signal of the sensor into physical quantities, e.g. speed or force, and/or taking time derivatives, and/or taking time values, and/or taking force values, and/or others.
  • the derived data may just be displayed as numbers and/or graphs, in a preferred embodiment, it is used to assign tasks to the user, e.g. exercises how to contract and relax the pelvic floor muscles.
  • the tasks are accompanied by various visual and/or acoustic and/or haptic output.
  • the step of outputting the processed data comprises displaying an avatar that moves in response to the processed data, in particular wherein the avatar moves in at least one dimension.
  • the avatar is preferably a visual representation of the pelvic floor muscles, or it may be a matchstick man or a cartoon animal.
  • the avatar moves arms and legs remaining in one place, while in another embodiment, it moves its whole body in at least one dimension.
  • the avatar moves in a predefined manner, e.g. with a constant speed, in one dimension, while moving in response to the processed data in a second dimension.
  • the app performing the method resembles a game, in which the user controls the movements of the avatar by contraction/relaxation of the pelvic floor muscles. Due to this "gamification” or “exergaming” (exercise plus gaming), the user is motivated for the training.
  • a preferred embodiment of the method comprises offering modes to the user, and in response to a selection of a mode, applying the mode in controlling the software.
  • the software supports the modes of training power and/or endurance and/or coordination of the pelvic floor muscles.
  • Preferably tasks are assigned to the user for every mode corresponding to a training of the different criteria of pelvic floor activity.
  • the method comprises receiving additional data indicative of an activity of abdominal muscles of the user, processing the received additional data, and outputting the processed additional data.
  • the received additional data it is possible to detect a co-contraction of the abdominal muscles.
  • the received data that should be indicative of an activity of the pelvic floor muscles may at least partially be caused by an activity of the abdominal muscles.
  • the received data may be attributed to an activity of the pelvic floor muscles, if and only if the received additional data indicates negligible activity of the abdominal muscles, e.g. exceeding the activity of the abdominal muscles in an idle state by at most 2 times its standard deviation.
  • the received additional data is shown to the user as visual and/or acoustic and/or haptic output as a self-control in order to avoid a faulty execution of the training. While the spurious effect of an activity of the gluteal muscles is kept out of the data by the rigidity and the shape of the housing, for a prevention of spurious effects of the abdominal muscles, preferably an additional sensor is required, see also below.
  • the steps of the method are performed automatically on a remote electronic device such as a smart phone, which preferably is electronically coupled to the device e.g. via Bluetooth.
  • a remote electronic device such as a smart phone
  • the routine for determining the calibration values is started and executed automatically, as is the processing of the received data after the determination of the calibration values.
  • one or more of the processed data and the derived data is stored in the remote electronic device, in order to allow the user to compare his/her performances to performances of the past.
