Description

Sports rehabilitation monitoring system

Technical Field

The application relates to the field of exercise rehabilitation equipment, in particular to an exercise rehabilitation monitoring system.

Background

The rehabilitation training can help people recover muscle functions and improve the activity of daily life. In exercise rehabilitation therapy, the higher the state recognition degree of the limb is, the clearer the rehabilitation condition of the limb is, and a plurality of rehabilitation techniques are currently applied to actual rehabilitation therapy. Among them, exercise rehabilitation is a comprehensive exercise-based rehabilitation therapy aimed at helping patients recover their physiological functions, physical exertion capacity and activity autonomy. It helps patients to recover and improve joint range of motion, strength, balance and coordination, locomotor efficiency and posture by designing specific sports and using a series of sports and training skills, thereby improving their quality of life and independence. However, the traditional exercise rehabilitation therapy needs to be performed under the guidance of doctors or therapists, and the rehabilitation therapy mode is not flexible enough and is difficult to adapt to individual rehabilitation requirements.

Various techniques are currently used in exercise rehabilitation therapy, including, for example, motion tracking techniques, motion capturing techniques, electrophysiology techniques, and electromyography techniques. Among them, the motion tracking technology and the motion capturing technology are mainly used for monitoring and identifying the position and the motion of the user, and the electrophysiology technology and the electromyography technology are mainly used for monitoring and identifying the muscle activity state of the user. In particular, electrophysiological techniques such as electrolyte sensing are techniques that utilize the conductivity of an electrolyte to detect the conductivity of a living organism. The technique can acquire the muscle activity state of the user, namely, identify the contraction condition of the muscle in the exercise rehabilitation therapy. Electrophysiological techniques require implanted sensors and thus have comfort and privacy concerns. Electromyography (EMG) is a common method of monitoring muscle activity, but can only measure action potentials of muscle movement due to neural activity, and is only suitable for small-scale muscle monitoring; and the captured signal is in the same order of magnitude as the mechanical noise, it is difficult to separate the effective signal. Therefore, the electrophysiological technique and the electromyography technique, although both of which can be applied to exercise rehabilitation therapy for identifying the exercise state of the muscle, have certain limitations.

Aiming at the problem that the current muscle movement state monitoring mode in the exercise rehabilitation therapy has larger use limitation, no effective solution is proposed at present.

Referring to fig. 1, in the present application there is provided a sports rehabilitation monitoring system comprising: a wearable electrical impedance tomography device 100 and a status feedback device 200, the wearable electrical impedance tomography device 100 comprising a data processing unit 120 and at least two electrode arrays 110; at least two electrode arrays 110 are electrically connected to the data processing unit 120; at least two electrode arrays 110, configured to be disposed at two ends of a target portion of a subject, respectively, so as to acquire physical sign data of the target portion of the subject in real time; the data processing unit 120 sends the sign data to the state feedback device 200 in real time; the state feedback device 200 feeds back muscle information of the target site of the subject in real time based on the sign data.

In some of these embodiments, the exercise rehabilitation monitoring system is comprised of a wearable electrical impedance tomography device 100 and a state feedback device 200. The wearable electrical impedance tomography device 100 refers to an electrical impedance tomography device that can be worn by a subject, comprising at least two electrode arrays 110. In use, at least two electrode arrays 110 are disposed at two ends of the target portion of the subject, respectively, which means that at least one electrode array 110 is disposed at each end of the target portion of the subject. And when the target site is wide, the electrode array 110 may be additionally disposed in the middle of the target site. For example, when monitoring the thigh of a subject is desired, two electrode arrays 110 may be uniformly applied to the upper and lower portions of the thigh, respectively.

Wherein each electrode array 110 is made up of a plurality of electrodes, for example, the electrode array 110 may be made up of 16 standard ECG (electrocardiogram) medical electrodes. When the electrode array 110 works, one pair of electrodes applies weak current excitation, and then corresponding voltage values on the other electrode pairs are measured; and switching a pair of electrodes to excite, and measuring the corresponding voltage values on the rest electrode pairs. The electrical impedance tomography device can calculate the electrical impedance distribution of the measured part based on the measured voltage value, and can image based on the electrical impedance distribution. The above is the basic principle of electrical impedance imaging (EIT). The sign data in this embodiment therefore includes electrical impedance distribution data.

After the data processing unit 120 generates electrical impedance distribution data based on the voltage and current data, the electrical impedance distribution data is transmitted to the state feedback device 200. The electrical impedance distribution data may determine a muscle state of the target site, such as determining a muscle force state of the target site, which is more relaxed or more stressed. Therefore, the state feedback device 200 can feedback the muscle information of the target part of the subject based on the electrical impedance distribution data, so that the subject can conveniently acquire the muscle state of the target part in real time, and whether the subject performs the rehabilitation action more normally or not can be judged.

It should be noted that the present application is a new application to EIT technology. In conventional EIT technology, an electrode array 110 is usually attached to a target site, that is, a circle of electrodes is attached to the target site, so as to obtain voltage and current data of a narrower target site corresponding to a plane where the circle of electrodes are located, thereby only obtaining electrical impedance distribution of a certain fault accurately and obtaining a muscle state of the fault site. In the case of sports rehabilitation monitoring, however, it is often necessary to monitor the entire length of muscle in a wide target site. In the present application, therefore, at least two electrode arrays 110 are respectively disposed at both ends of the target site, so that at least muscle states at both ends of the target site can be obtained, and thus the entire muscle state in the target site can be obtained based on the analysis of the muscle states at both ends. The state of the whole muscle can be determined, for example, by means of a data fitting.

Thus, by employing at least two electrode arrays 110 in the present application, the overall muscle status in the target site can be monitored more accurately. Unlike conventional applications of EIT techniques, an electrode array 110 is used to monitor the muscle state at a fault location.

Meanwhile, compared with the muscle movement state monitoring mode in the current movement rehabilitation therapy, the movement rehabilitation monitoring system provided by the application does not need to implant a sensor in a human body, can realize large-range muscle monitoring, and has low signal noise of the EIT technology. Therefore, the application provides a muscle movement state monitoring mode and a movement rehabilitation monitoring system with lower use limitation, and solves the problem that the current muscle movement state monitoring mode in movement rehabilitation treatment has larger use limitation.

As described above, when the exercise rehabilitation status of the subject is monitored in real time by the wearable electrical impedance tomography apparatus 100, the exercise rehabilitation status is also fed back to the subject in real time by the status feedback apparatus 200. Alternatively, the state feedback device 200 may employ voice and/or image feedback. Wherein the image feedback is more intuitive than the voice feedback.

Thus, referring to fig. 2, in some embodiments thereof, the state feedback device 200 comprises: a visualization device 210; the data processing unit 120 transmits the sign data to the visualization device 210 in real time; the visualization device 210 displays muscle information of the target site of the subject in real time based on the sign data. In the present embodiment, the visualization apparatus 210 feeds back muscle information of a target site of a subject in the form of an image based on the EIT technique. The muscle information comprises information such as muscle morphology, muscle stress state and the like, so that a subject can intuitively know the muscle state of the target part of the subject through images, and whether the exercise rehabilitation action is executed in place can be better judged. Among them, image forms for feeding back muscle information are various. For example, a muscle image of a target site of a subject may be directly displayed, and the muscle image may truly restore the muscle state of the target site of the subject. The subject can intuitively observe the muscle morphology change of the target site. In addition to directly displaying the muscle image, other graphics may also characterize the corresponding muscle, with the change in the morphology of the muscle being characterized by the change in the graphics, but in a manner that is less intuitive than the muscle image.

Thus, in some preferred embodiments, the muscle information includes a muscle image, i.e., the visualization device 210 reveals changes in the muscle morphology of the target site of the subject by displaying the muscle image. Further, a plurality of different types of muscles may be included in the target site to be detected, and different colors may be used in the muscle image to distinguish between the different types of muscles in order to facilitate the subject in distinguishing between the different types of muscles.

In a preferred embodiment, when the muscle image includes at least two muscles, the visualization device 210 displays the adjacent two muscles in different hues. For example, for adjacent first and second muscles, the first muscle may appear red and the second muscle may appear yellow. So that the subject can distinguish between different types of muscles by color, so that the subject can more intuitively understand the morphological changes of the different types of muscles.

It should be further noted that, by the morphological change of the muscles, the subject can directly determine the stress state of the corresponding muscles, but this requires a certain experience of the subject.

Further, in a preferred embodiment, the visualization device 210, upon determining the target athletic event in response to a user selection operation, uses the color brightness to represent the engagement of the muscle in the target athletic event. In this embodiment, the visualization device 210 uses different color brightness to represent different muscle engagement. For example, assuming that a certain muscle is displayed in yellow, when a subject performs a certain rehabilitation activity, if the participation of the muscle in the rehabilitation activity is low, it may be understood that the muscle is less stressed and less contributed to performing the rehabilitation activity, the muscle may be displayed in light yellow, and if the participation of the muscle in the rehabilitation activity is high, the muscle may be displayed in dark yellow. Through the difference of the color brightness, the subject can intuitively know the participation degree of a certain muscle in the current rehabilitation action, namely the information such as the strength of the muscle, the contribution degree of the muscle to the current rehabilitation action, and the like, so that the subject can conveniently adjust the strength of the muscle to make a more standard rehabilitation action.

The degree of exertion or engagement of the muscles required for different rehabilitation activities is different. If the subject wants to accurately judge whether the subject performs the current rehabilitation motion in a standard way, the subject needs to know not only the muscle state of the target part of the subject, but also the standard muscle state required to be reached by the current rehabilitation motion. For a partially experienced subject, it may be empirically determined whether the subject is performing the current rehabilitation activity on his own; but it is difficult to accurately judge for a subject with partial inexperience.

Based thereon, the visualization device 210 also provides a standard reference function. In some of these embodiments, several types of target muscle information corresponding to different motion events are preconfigured in the visualization device 210; the visualization device 210 includes a first display area and a second display area; after determining the target exercise event in response to the user's selection operation, the visualization device 210 displays the target muscle information corresponding to the target exercise event in the first display area and displays the current muscle information of the target site of the subject in the second display area. Specifically, the target muscle information for a certain exercise event includes the muscle state that the subject should achieve to perform the exercise event in a standardized manner. The visualization device 210 comprises at least two areas for displaying the target muscle information and the actual muscle information of the target site of the subject, respectively. The target muscle information is used as a reference, so that the subject can intuitively judge whether the subject performs rehabilitation actions in a standard manner.

Illustratively, it has been described above in some embodiments that muscle information may be fed back using muscle images and different types of muscles may be represented using different hues and degrees of engagement of the muscles in a target movement event may be represented using color brightness. Then after the subject determines a rehabilitation maneuver to be performed, the visualization device 210 displays the standard muscle image in the first display area and the actual muscle image of the target site of the subject in real time in the second display area. By virtue of the correspondence in hue, the subject can rapidly correspond the same muscle in both images for comparison. Assuming that a certain muscle is represented in red and has a higher participation in the current rehabilitation activity, the muscle is displayed in dark red in the standard muscle image, if the muscle is only displayed in light red in the actual muscle image of the subject, which indicates that the participation of the muscle is insufficient, the subject should increase the muscle strength when performing the current rehabilitation activity.

Therefore, the visualization device 210 facilitates the subject to more simply and intuitively determine whether the subject has performed the rehabilitation motion in a standard manner by feeding back the standard muscle information, thereby adjusting the performance of the subject to improve the exercise rehabilitation effect.

There is typically interaction between the visualization device 210 and the user or subject. For an ordinary user, a handheld controller or a touch display can be directly adopted. Both of the above interactions may be inconvenient in view of subject specificity.

Thus, in some of these embodiments, the visualization device 210 includes a third display area and an inertial sensor; displaying in a third display area a number of interaction options corresponding to different motion events, an inertial sensor for capturing head motion of the subject; the visualization device 210 identifies a user's selection operation for several interactive options based on the subject's head movements. In particular, the inertial sensor may be worn on the head of the subject for capturing head movements of the subject. The visualization device 210 may interact with the subject based on the subject's head movements. For example, a cursor may be positioned in the third display region, and the subject may control cursor movement via head movement, and be determined or cancelled via some specific action representation.

As described above, the exercise rehabilitation monitoring system mainly includes the wearable electrical impedance tomography apparatus 100 and the state feedback apparatus 200, and the wearable electrical impedance tomography apparatus 100 is mainly used to monitor the muscle state of the target portion of the subject, and perform feedback through the state feedback apparatus 200. The subject can conveniently judge whether the subject performs rehabilitation actions in a standard way from the muscle state angle. Meanwhile, the subject can judge whether the subject performs rehabilitation actions in a standard manner or not according to the overall pose.

Thus, referring to fig. 3, in some embodiments thereof, the monitoring system further comprises: a pose monitoring device 300; the pose monitoring device 300 is configured to obtain pose data of a subject in real time, and send the pose data to the state feedback device 200 in real time; the state feedback device 200 also feeds back the pose information of the subject in real time based on the pose data. Specifically, the pose monitoring device 300 is configured to obtain the position data and the pose data of the subject in real time, and the state feedback apparatus 200 may also feedback the position information and the pose information of the subject. The position information includes the current position of the subject, and the posture information includes the current posture of the subject, that is, the current action posture. The state feedback device 200 feeds back muscle information and pose information at the same time, and the subject can determine whether the muscle of the target part is exerting a correct force or not, and can determine whether the corresponding action pose is executed in place or not. For example, when rehabilitation is used as leg lifting, the subject can judge whether the leg lifting height or angle is in place or not through pose information. Among other things, the pose monitoring device 300 includes an optical motion capture device or a wearable motion sensor. Both can accurately acquire pose data of the subject.

The pose information is mainly to feed back the position and pose of the subject, so that the feedback via the visualization device 210 is more suitable. In some embodiments, the pose information comprises a pose image comprising a character model that simulates the pose of the subject; the muscle image is at a target site of the character model that corresponds to the target site of the subject, i.e., the visualization device 210 displays the muscle image of the target site of the subject at the corresponding site in the character model. Specifically, the visualization device 210 is configured with a character model, and the character model can simulate the pose of the subject through the pose data acquired by the pose monitoring device 300, so that the subject can intuitively observe the position and the action of the subject. Accordingly, the muscle image of the target site of the subject may be displayed directly at the corresponding site in the character model.

Further, if the visualization device 210 displays the muscle image through a conventional display, it may be difficult for the subject to clearly and stably observe the contents in the display since the subject is in a moving state while performing the rehabilitation exercise. Preferably, the visualization device 210 may employ a Virtual Reality (VR) device. The subject wears the head-mounted VR device, so that on one hand, muscle images are clearly and stably observed in the movement process, and on the other hand, the VR device supports three-dimensional imaging, and the three-dimensional muscle images can restore the actual muscle state more. Furthermore, considering the specificity of the rehabilitation population, instead of using a traditional handheld VR controller, eye movement and head movement may be captured by inertial sensors on the VR headset to interact with the rehabilitation user interface.

The technical scheme of the application is described by a specific embodiment as follows.

Referring to fig. 4, in one particular embodiment, the athletic rehabilitation monitoring system includes: a data processing unit 120, at least two electrode arrays 110, a VR device 220, and an optical motion capture device 310. The two electrode arrays 110 are connected to a data processing unit 120 (EIT sensing board), the data processing unit 120 is electrically connected to a VR device 220 for transmitting muscle data of a subject thereto, and an optical motion capture device 310 is electrically connected to the VR device 220 for transmitting pose data of the subject thereto.

The wearable electrical impedance tomography device is based on an electrical impedance imaging technology (EIT), which is an imaging technology for knowing the distribution of internal resistance by measuring external resistance, and has wide monitoring range and low sensitivity to mechanical noise. It derives the internal resistance distribution by applying a voltage to the surface of the object and measuring the current distribution. Through wearable electrical impedance tomography device, VR equipment 220 can carry out the visualization with human muscle, helps the user to know the motion participation condition of own muscle in real time, assists in carrying out rehabilitation training.

To track the motion gestures of a user in real time, techniques are employed by which the optical motion capture device 310 tracks and analyzes motion information. Motion Capture (Motion Capture) refers to a technique for recording data and restoring a posture of a Motion of a human body structure using an external device. The optical motion capture device 310 is typically comprised of two parts, hardware and software. The hardware comprises rigid body marking points, optical acquisition equipment, transmission equipment, data processing equipment and the like; the software comprises functional modules such as system setting, space calibration, motion capture, data processing, a 3D model mapping model and the like. In motion rehabilitation therapy, the optical motion capture device 310 may be used to evaluate a patient's motor skills, motion efficiency, and motor function. The optical motion capture device 310 generates three-dimensional motion data by tracking the movement of the patient's body so that the patient's motion trend and treatment needs can be more accurately identified.

The wearable electrical impedance tomography device can monitor the muscle activity condition in real time through an electrical impedance tomography technology. The optical motion capture device 310 may use hardware such as cameras and sensors to track the user's motion in real time and combine the data with EIT readings via software. Virtual Reality (VR) based rehabilitation platforms use VR device 220 (head-mounted, handheld, earphone, etc. devices) to help users achieve self-rehabilitation training by providing interactive games and training items to the users. In terms of product form and interaction mode, the user interface of the device is simple and easy to use, detailed exercise data and training feedback are provided, and meanwhile, the training strength and content can be automatically adjusted according to the rehabilitation progress and the requirements of a user.

With reference to fig. 5, a description will be given of a large arm as a target portion. Before use, two electrode arrays 110 (which may be an array of 16 standard ECG medical electrodes) are applied uniformly to the upper and lower portions of a user's large arm and the electrodes are connected to a data processing unit 120 (EIT sensing plate). In use, the electrodes are attached to the skin of a subject, and a hand muscle image is constructed and transmitted to VR device 220, and animation display interface 221 of VR device 220 displays the muscle image. To track the user's motion gestures in real time, the motion data acquired by the optical motion capture device 310 may be mapped onto the animation display interface 221 of the VR device 220 to present the user's position and gesture in real time. The three-dimensional real-time dynamic VR technology-based rehabilitation user interface has a floating control panel for selecting a number of different limb training modes. The interface also contains the correct actions and target muscle groups, the movements of the user and the participation of the muscles. Different muscles are distinguished by using different colors (e.g., red for quadriceps femoris, green for sartorius, blue for popliteal, yellow for adductor), darker colors indicating higher participation of the muscle group. Furthermore, considering the specificity of the rehabilitation population, instead of using a traditional handheld VR controller, eye tracking and head movements are captured by inertial sensors on the VR headset to interact with the rehabilitation user interface. Through muscle participation visualization, the accuracy of the user's actions is improved.
