Description

Technical Field

[0001] This application relates to the field of sports rehabilitation equipment, and in particular to a sports rehabilitation monitoring system. Background Technology

[0002] Rehabilitation training helps people restore muscle function and improve their daily living activities. In sports rehabilitation, higher accuracy in recognizing limb status leads to a clearer understanding of the limb's recovery progress. Currently, numerous rehabilitation techniques are applied in practical rehabilitation treatment. Sports rehabilitation is a comprehensive, movement-based approach designed to help patients restore their physiological functions, physical activity, and autonomy. It involves designing specific exercise programs and utilizing a series of movements and training techniques to help patients restore and improve joint range of motion, strength, balance and coordination, movement efficiency, and posture, thereby improving their quality of life and independence. However, traditional sports rehabilitation requires guidance from a doctor or therapist, making it inflexible and difficult to adapt to individualized rehabilitation needs.

[0003] Currently, various technologies are applied in sports rehabilitation therapy, including motion tracking, motion capture, electrophysiology, and electromyography (EMG). Motion tracking and motion capture are primarily used to monitor and identify a user's position and movements, while electrophysiology and EMG are mainly used to monitor and identify the user's muscle activity. Specifically, electrophysiology, such as electrolyte sensing, utilizes the conductivity of electrolytes to detect the electrical conductivity of a biological organism. This technology can acquire the user's muscle activity status, i.e., identify muscle contraction, during sports rehabilitation therapy. However, electrophysiology requires implanted sensors, thus raising comfort and privacy concerns. Electromyography (EMG) is a commonly used method for monitoring muscle activity, but it can only measure the action potentials of muscle movement caused by neural activity, making it suitable only for monitoring small areas of muscle; moreover, the captured signal is on the same order of magnitude as mechanical noise, making it difficult to separate the effective signal. Therefore, while both electrophysiology and EMG technologies can be applied in sports rehabilitation therapy to identify muscle movement status, they all have certain limitations.

[0004] There is currently no effective solution to the problem that the existing methods for monitoring muscle movement status in sports rehabilitation therapy have significant limitations. Summary of the Invention

[0005] This invention provides a sports rehabilitation monitoring system to address the significant limitations of current methods for monitoring muscle movement status in sports rehabilitation therapy.

[0019] In some of these embodiments, after determining a target motion event in response to a user's selection, the visualization device uses color brightness to represent the degree of muscle involvement in the target motion event.

[0020] In some embodiments, the monitoring system further includes: a pose monitoring device;

[0021] The posture monitoring device is used to acquire the subject's posture data in real time and send the posture data to the status feedback device in real time.

[0022] The state feedback device also provides real-time feedback on the subject's posture information based on the posture data.

[0023] In some embodiments, the pose information includes a pose image, which includes a human model simulating the pose of the subject;

[0024] The muscle image is located at the target area of ​​the human model, and the target area of ​​the human model corresponds to the target area of ​​the subject.

[0025] In some embodiments, the pose monitoring device includes an optical motion capture device or a wearable motion sensor.

[0026] In some of these embodiments, the visualization device includes a third display area and an inertial sensor;

[0027] The third display area displays several interactive options corresponding to different motion events, and the inertial sensor is used to capture the subject's head movements;

[0028] The visualization device identifies the user's selection of several interaction options based on the subject's head movements.

[0029] Compared to current methods of monitoring muscle movement status in sports rehabilitation, the sports rehabilitation monitoring system provided in this invention does not require the implantation of sensors in the human body, can achieve monitoring of a wider range of muscles, and features low signal noise from EIT technology. Therefore, this invention provides a muscle movement status monitoring method and sports rehabilitation monitoring system with fewer limitations, overcoming the significant limitations of current muscle movement status monitoring methods in sports rehabilitation.

[0039] Reference Figure 1This invention provides a sports rehabilitation monitoring system, which includes a wearable electrical impedance tomography (EIT) device 100 and a status feedback device 200. The wearable EIT device 100 includes a data processing unit 120 and at least two electrode arrays 110. The at least two electrode arrays 110 are electrically connected to the data processing unit 120. The at least two electrode arrays 110 are respectively positioned at both ends of a target area of ​​the subject to acquire vital sign data of the target area in real time. The data processing unit 120 sends the vital sign data to the status feedback device 200 in real time. The status feedback device 200 provides real-time feedback on muscle information of the target area of ​​the subject based on the vital sign data.

[0040] In some embodiments, the exercise rehabilitation monitoring system comprises a wearable electrical impedance tomography (EIT) device 100 and a status feedback device 200. The wearable EIT device 100 is an EIT device that can be worn by the subject and includes at least two electrode arrays 110. During use, the at least two electrode arrays 110 are respectively positioned at both ends of the subject's target area, meaning that at least one electrode array 110 is positioned at each end of the target area. When the target area is wide, an additional electrode array 110 can be positioned in the middle of the target area. For example, when monitoring the subject's thigh, two electrode arrays 110 can be evenly applied to the upper and lower parts of the thigh, respectively.

[0041] Each electrode array 110 consists of multiple electrodes; for example, it can be composed of 16 standard ECG (electrocardiogram) medical electrodes. When the electrode array 110 is in operation, a weak current excitation is applied to one pair of electrodes, and the corresponding voltage value on the remaining electrode pairs is measured. Then, a pair of electrodes is switched for excitation, and the corresponding voltage value on the remaining electrode pairs is measured again. The electrical impedance tomography (EIT) device can calculate the electrical impedance distribution of the measured area based on the measured voltage values ​​and can perform imaging based on the electrical impedance distribution. This is the basic principle of electrical impedance tomography (EIT). Therefore, the vital sign data in this embodiment includes electrical impedance distribution data.

[0042] After the data processing unit 120 generates impedance distribution data based on the voltage and current data, it sends the impedance distribution data to the state feedback device 200. The impedance distribution data can determine the muscle state of the target area, such as the muscle exertion state of the target area, whether it is relatively relaxed or relatively tense. Therefore, the state feedback device 200 can provide feedback on the muscle information of the target area of ​​the subject based on the impedance distribution data, so that the subject can obtain the muscle state of the target area in real time and thus judge whether he or she is performing the rehabilitation movements in a relatively standard manner.

[0043] It should be noted that this invention is a novel application of EIT technology. In traditional EIT applications, an electrode array 110 is typically attached to the target area, i.e., a ring of electrodes is placed around the target area to acquire voltage and current data for a narrow target region corresponding to the plane of that ring of electrodes. This only provides a relatively precise understanding of the impedance distribution of a specific segment, thus revealing the muscle state at that segment. However, in sports rehabilitation monitoring scenarios, it is usually necessary to monitor the entire muscle segment within a wider target area. Therefore, in this invention, at least two electrode arrays 110 are respectively placed at both ends of the target area, allowing the acquisition of muscle states at at least both ends of the target area. This enables analysis based on the muscle states at both ends to determine the overall muscle state within the target area. For example, the overall muscle state can be determined through data fitting.

[0044] Therefore, by employing at least two electrode arrays 110, the present invention can more accurately monitor the entire muscle state in the target area. This differs from traditional EIT technology applications, which use a single electrode array 110 to monitor the muscle state at a specific fracture site.

[0045] Meanwhile, compared to current methods of monitoring muscle movement status in sports rehabilitation, the sports rehabilitation monitoring system provided in this invention does not require the implantation of sensors in the human body, can achieve monitoring of a wider range of muscles, and features low signal noise from EIT technology. Therefore, this invention provides a muscle movement status monitoring method and sports rehabilitation monitoring system with fewer limitations in application, overcoming the significant limitations of current muscle movement status monitoring methods in sports rehabilitation.

[0046] As described above, while the wearable electrical impedance tomography (EIT) device 100 monitors the subject's motor rehabilitation status in real time, the status feedback device 200 also provides real-time feedback on the subject's motor rehabilitation status. Optionally, the status feedback device 200 can use voice and / or image feedback. Image feedback is more intuitive than voice feedback.

[0047] Therefore, refer to Figure 2In some embodiments, the status feedback device 200 includes: a visualization device 210; a data processing unit 120 sends vital sign data to the visualization device 210 in real time; and the visualization device 210 displays muscle information of the target area of ​​the subject in real time based on the vital sign data. In this embodiment, the visualization device 210 uses EIT technology to provide feedback on the muscle information of the target area of ​​the subject in the form of images. The muscle information includes information such as muscle morphology and muscle exertion state, so that the subject can intuitively understand the muscle state of their target area through images and better judge whether the exercise rehabilitation movements have been performed correctly. The image formats used to provide feedback on muscle information are diverse. For example, an image of the muscle of the target area of ​​the subject can be directly displayed, which can realistically reproduce the muscle state of the target area. The subject can intuitively observe changes in muscle morphology of the target area. In addition to directly displaying muscle images, other graphics can be used to represent the corresponding muscles, and changes in muscle morphology can be represented by graphic changes, but this method is not as intuitive as a muscle image.

[0048] Therefore, in some preferred embodiments, muscle information includes muscle images, meaning that the visualization device 210 displays muscle morphological changes in the target area of ​​the subject by showing muscle images. Furthermore, the target area being detected may contain multiple different types of muscles. To facilitate the subject's differentiation between different types of muscles, different colors can be used in the muscle images to distinguish between them.

[0049] In a preferred embodiment, when the muscle image includes at least two muscles, the visualization device 210 displays the two adjacent muscles using different color hues. For example, for an adjacent first muscle and a second muscle, the first muscle may be displayed in red, and the second muscle in yellow. This allows the subject to distinguish different types of muscles by color, enabling them to more intuitively understand the morphological changes of different muscle types.

[0050] It should be further explained that subjects can directly judge the force exertion state of the corresponding muscles by observing changes in muscle morphology, but this requires subjects to have a certain amount of experience.

[0051] Furthermore, in a preferred embodiment, after determining the target movement event in response to the user's selection operation, the visualization device 210 uses color brightness to represent the degree of muscle involvement in the target movement event. In this embodiment, the visualization device 210 uses different color brightness to represent different muscle involvement levels. For example, assuming a certain muscle is displayed in yellow, when the subject performs a certain rehabilitation movement, if the muscle's involvement in the rehabilitation movement is low, it can be understood that the muscle exerts less force and contributes less to the performance of the rehabilitation movement, then the muscle can be displayed in light yellow; if the muscle's involvement in the rehabilitation movement is high, then the muscle can be displayed in dark yellow. Through the difference in color brightness, the subject can intuitively understand the involvement of a certain muscle in the current rehabilitation movement, that is, the degree of muscle exertion, its contribution to the performance of the current rehabilitation movement, etc., so that the subject can adjust muscle exertion and perform more standard rehabilitation movements.

[0052] Different rehabilitation exercises require varying degrees of muscle exertion or involvement. For a subject to accurately determine whether they have performed the exercise correctly, they need to understand not only the muscle state of the target area but also the standard muscle state required for the exercise. Experienced subjects can judge their performance based on experience; however, less experienced subjects may find it difficult to make an accurate assessment.

[0053] Based on this, the visualization device 210 also provides a standard reference function. In some embodiments, the visualization device 210 is pre-configured with several types of target muscle information corresponding to different movement events; the visualization device 210 includes a first display area and a second display area; after the visualization device 210 determines the target movement event in response to the user's selection operation, the first display area displays the target muscle information corresponding to the target movement event, and the second display area displays the current muscle information of the target part of the subject. Specifically, the target muscle information of a certain movement event includes the muscle state that the subject should achieve when performing the movement event correctly. The visualization device 210 includes at least two areas, respectively used to display the target muscle information and the actual muscle information of the target part of the subject. The target muscle information serves as a reference so that the subject can intuitively judge whether they have performed the rehabilitation movement correctly.

[0054] For example, as described above in some embodiments, muscle images can be used to provide feedback on muscle information, different hues can be used to represent different types of muscles, and color brightness can be used to represent the degree of muscle involvement in the target movement event. After the subject determines the rehabilitation movement to be performed, the visualization device 210 displays a standard muscle image in the first display area and a real-time image of the subject's actual muscle at the target site in the second display area. Through the correspondence in color hue, the subject can quickly match the same muscles in the two images for comparison. Assuming a muscle is represented in red and has a high degree of involvement in the current rehabilitation movement, the muscle will be displayed in dark red in the standard muscle image. If the muscle is only displayed in light red in the subject's actual muscle image, it indicates insufficient muscle involvement, and the subject should increase the exertion of that muscle when performing the current rehabilitation movement.

[0055] Therefore, by providing feedback on standard muscle information, the visualization device 210 makes it easier and more intuitive for subjects to judge whether they have performed the rehabilitation movements correctly, thereby adjusting their movement execution to improve the effect of exercise rehabilitation.

[0056] Typically, the visualization device 210 interacts with the user or subject. For ordinary users, a handheld controller or a touchscreen display can be used. However, considering the specific needs of the subject, both of these interaction methods may be inconvenient.

[0057] Therefore, in some embodiments, the visualization device 210 includes a third display area and an inertial sensor; the third display area displays several interactive options corresponding to different motion events, and the inertial sensor is used to capture the subject's head movements; the visualization device 210 identifies the user's selection of the several interactive options based on the subject's head movements. Specifically, the inertial sensor can be worn on the subject's head to capture the subject's head movements. The visualization device 210 can interact with the subject based on the subject's head movements. For example, a cursor can be set in the third display area, and the subject can control the cursor movement through head movements, and indicate confirmation or cancellation through specific actions.

[0058] As described above, the exercise rehabilitation monitoring system mainly includes a wearable electrical impedance tomography (EIT) device 100 and a status feedback device 200. The wearable EIT device 100 is mainly used to monitor the muscle status of the target area of ​​the subject and provides feedback through the status feedback device 200. This allows the subject to judge whether they have performed the rehabilitation movements correctly from the perspective of muscle status. At the same time, the subject can also judge whether they have performed the rehabilitation movements correctly from the perspective of overall posture.

[0059] Therefore, refer to Figure 3 In some embodiments, the monitoring system further includes: a pose monitoring device 300; the pose monitoring device 300 is used to acquire the pose data of the subject in real time and send the pose data to the status feedback device 200 in real time; the status feedback device 200 also provides real-time feedback on the pose information of the subject based on the pose data. Specifically, the pose monitoring device 300 is used to acquire the position data and posture data of the subject in real time, while the status feedback device 200 also provides feedback on the position information and posture information of the subject. The position information includes the subject's current position, and the posture information includes the subject's current posture, that is, the current action posture. The status feedback device 200 simultaneously provides feedback on muscle information and pose information, so the subject can not only judge whether the muscles of the target area are exerting force correctly, but also judge whether the corresponding action posture is performed correctly. For example, when the rehabilitation action is a leg raise, the subject can judge whether the leg raise height or angle is correct through pose information. The pose monitoring device 300 includes an optical motion capture device or a wearable motion sensor. Both can accurately acquire the subject's pose data.

[0060] Pose information primarily provides feedback on the subject's position and posture; therefore, visualization device 210 is more suitable for providing this feedback. In some embodiments, pose information includes pose images, which in turn include a person model simulating the subject's pose. Muscle images are located at target areas of the person model, and these target areas correspond to the subject's target areas. Specifically, visualization device 210 displays the muscle images of the subject's target areas at the corresponding locations within the person model. In concretely, visualization device 210 includes a person model that can simulate the subject's pose using pose data acquired by pose monitoring device 300, allowing the subject to intuitively observe their own position and movements. Correspondingly, the muscle images of the subject's target areas can be directly displayed at the corresponding locations within the person model.

[0061] Furthermore, if the visualization device 210 displays muscle images on a conventional monitor, the subject may find it difficult to clearly and stably observe the content on the monitor because they are in motion while performing rehabilitation exercises. More preferably, the visualization device 210 can be a head-mounted VR (Virtual Reality) device. By wearing the head-mounted VR device, the subject can clearly and stably observe muscle images during exercise; moreover, the VR device supports 3D imaging, and the 3D muscle images can more accurately reproduce the actual muscle state. In addition, considering the specific needs of the rehabilitation population, traditional handheld VR controllers can be avoided; instead, inertial sensors on VR headsets can capture eye and head movements, enabling interaction with the rehabilitation user interface.

[0062] The technical solution of the present invention will be further described below through a specific embodiment.

[0063] Reference Figure 4 In one specific embodiment, the exercise 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 the data processing unit 120 (EIT sensor plate), the data processing unit 120 is electrically connected to the VR device 220 for transmitting muscle data of the subject to it, and the optical motion capture device 310 is electrically connected to the VR device 220 for transmitting pose data of the subject to it.

[0064] Wearable electrical impedance tomography (EIT) devices are based on electrical impedance imaging (EIT), an imaging technique used to understand the internal resistance distribution by measuring external resistance. It offers a wide monitoring range and low sensitivity to mechanical noise. It derives the internal resistance distribution by applying a voltage to the surface of an object and measuring the current distribution. Using wearable EIT devices, VR devices 220 can visualize human muscles, helping users understand their muscle movement in real time and assisting in rehabilitation training.

[0065] To track users' movements in real time, an optical motion capture device 310 is used to track and analyze motion information. Motion capture refers to the technology of recording and reconstructing the movements of the human body using external devices. The optical motion capture device 310 typically consists of hardware and software. The hardware includes rigid body markers, optical acquisition devices, transmission devices, and data processing devices; the software includes functional modules such as system settings, spatial calibration, motion capture, data processing, and 3D model mapping. In sports rehabilitation therapy, the optical motion capture device 310 can be used to assess patients' motor skills, movement efficiency, and motor function. By tracking the patient's body movements and generating three-dimensional motion data, the optical motion capture device 310 can more accurately identify the patient's movement trends and treatment needs.

[0066] Wearable electrical impedance tomography (EIT) devices can monitor muscle activity in real time using EIT technology. Optical motion capture devices 310 use hardware such as cameras and sensors to track user movement in real time and combine the data with EIT readings via software. Virtual reality (VR)-based rehabilitation platforms use VR devices 220 (headset, handheld devices, headphones, etc.) to help users achieve self-rehabilitation training by providing interactive games and training programs. In terms of product form and interaction mode, the device features a simple and easy-to-use user interface, provides detailed movement data and training feedback, and can automatically adjust training intensity and content according to the user's rehabilitation progress and needs.

[0067] Reference Figure 5 The procedure is explained using the upper arm as the target area. Before use, two electrode arrays 110 (which can consist of 16 standard ECG medical electrodes) are evenly applied to the upper and lower parts of the user's upper arm, and the electrodes are connected to the data processing unit 120 (EIT sensor plate). During use, the electrodes are connected to the subject's skin, which allows for the construction of hand muscle images, which are then transmitted to the VR device 220. The VR device 220's animation display interface 221 displays the muscle images. To track the user's movement posture in real time, motion data acquired by the optical motion capture device 310 can be mapped onto the VR device 220's animation display interface 221, presenting the user's position and posture in real time. The three-dimensional, real-time dynamic, VR-based rehabilitation user interface has a floating control panel for selecting several different limb training methods. The interface also includes the correct movements and target muscle groups, the user's movements, and muscle engagement. Different colors are used to distinguish different muscles (e.g., red for the quadriceps, green for the sartorius, blue for the hamstrings, and yellow for the adductors), with darker colors indicating a higher level of muscle group involvement. Furthermore, considering the specific needs of rehabilitation patients, traditional handheld VR controllers are not used. Instead, inertial sensors on VR headsets capture eye-tracking and head movements, enabling interaction with the rehabilitation user interface. Visualizing muscle involvement improves the accuracy of user movements.
