Abstract
The invention relates to a muscle injury rehabilitation training system based on myoelectric biofeedback, which comprises: the system comprises a surface electromyography system, a data processing center, a virtual reality scene interactive training system and a controllable training platform, and is used for rehabilitation treatment of body muscle injury.
Description
Technical Field
The invention relates to a clinical muscle injury evaluation and training system, in particular to a muscle injury evaluation and training system combining a visual-myoelectric biofeedback technology.
Background
Muscle damage is a common clinical condition. For treating muscle injury, except for drug treatment, rehabilitation exercise aiming at the injured muscle is the first choice of noninvasive conservative therapy.
Currently, clinical muscle training modalities include: bare-handed training, elastic band resistance training, instrument training, and the like. However, the muscle training mode is simple and boring, and lacks interest, and the compliance of patients is poor. Moreover, repeated single movements tend to cause the patient's tired mood.
To increase interest, clinical medicine has recently attempted to introduce Virtual Reality (VR) games into patient rehabilitation function training.
The virtual reality technology is a technology that a computer is used for generating a virtual environment (such as walking, fetching objects and the like) simulating real objects, and a patient is 'thrown' into the environment through a specific interaction tool (such as stereo glasses, sensing gloves and the like), so that the patient can directly and naturally interact with the virtual environment.
In recent years, virtual reality technology has begun to be applied to limb function and speech rehabilitation training. The simulation environment is displayed by using a computer and professional software and hardware, so that virtual interaction and feedback in the aspects of vision, hearing, touch, motion and the like are realized, a patient can feel personally on the scene, and the patient can finish controllable functional movement and operation in the virtual environment, thereby achieving the purpose of function reconstruction. Virtual reality technology is able to continually inspire and maintain the interest of repeated exercises of patients with feedback in diverse forms by programming a virtual environment. The development of the virtual reality technology fundamentally changes the traditional exercise rehabilitation mode and really combines labor and ease.
However, the technical defects of the existing virtual reality machine are that the products are all primary virtual reality training programs, the number of the programs is limited, and the choice is small. The training mode is a prefabricated simple scene simulation, the actions are repeated and programmed, the human-computer interaction is lacked, and the interest of the patient can be lost in the long term.
Clinically the signs of muscle damage conditions may be the same but the damaged muscles may differ, or the degree of damage may differ although the damaged muscles are the same. For example, leg pain is caused by leg muscle strain, and leg pain caused by leg muscle strain and leg pain caused by waist muscle damage. For another example, although patients with lumbago have lumbago, the damaged part of the lumbar muscle may be different. The same training action may not necessarily be used for patients with the same characteristics. At present, muscle rehabilitation training is blind, and accuracy and individual pertinence are lacked. As long as the symptoms of the disease are the same or similar, the same training action is applied, and the proper training action is finally found by continuous trial and error correction.
Currently, the evaluation of the degree of muscle damage and the rehabilitation training effect is mostly carried out by using a traditional evaluation scale (questionnaire) system, namely, by observing the physical activity of walking. However, this manual measurement and evaluation method has a high requirement on the subjective judgment ability of the doctor on the one hand, and on the other hand, it cannot realize real-time and quantitative evaluation.
As rehabilitation treatment progresses, the physical condition of a patient changes continuously, the activity amount and the activity intensity are changed, and previous evaluation cannot adapt to the changed condition. Because the traditional evaluation method cannot record and store the process data of the patient in the training process in time or in real time, the dynamic change and the dynamic training effect of the traditional evaluation method on muscle rehabilitation training can only be estimated approximately. However, in clinical rehabilitation, real-time changes in patient training are scientifically evaluated in time, and training intensity and training items are changed in time, which is a need for improving the efficiency and level of rehabilitation training. In addition, the real-time physical condition assessment can also meet the requirement that the patient urgently wants to know the self muscle function level and the improvement condition after training.
In recent years, a surface electromyographic signal detection method is applied to medical diagnosis and physical training.
Surface electromyogram (sEMG) is guided from the skin Surface through electrodes, records bioelectric signals during the activity of a neuromuscular system, and can accurately reflect the muscle contraction condition. The surface electromyography technology is applied to sports training, and is used for analyzing the contraction and fatigue conditions of target muscles in sports and analyzing the contraction sequence and coordination of different target muscles. Particularly, in the gradual load training, the surface myoelectricity has the advantages of simple and convenient detection process, small interference to actions, continuous detection, intuition, reliability and the like, and can ensure the accuracy of muscle evaluation and the training safety in the gradual load training test process.
Electromyographic biofeedback therapies have recently been developed based on surface electromyographic signal detection methods. The therapy is a method for recording weak electric signals during muscle contraction by means of surface myoelectric receiving equipment, converting the weak electric signals into easily perceived visual or auditory signals, and enabling a patient to adjust the muscle contraction degree according to the visual/auditory signals and to train himself. The exercise rehabilitation training device can provide feedback of training results of each time and achievement feedback after each group of exercises for the patient to perform exercise rehabilitation training, and is beneficial to improving the awareness and training enthusiasm of the patient on muscle contraction conditions. At present, the technology is applied to the rehabilitation of the paralyzed limb movement function of brain injury or spinal cord injury. Although the myoelectric biofeedback therapy can inform the patient who receives rehabilitation training whether the training action is correct or not in time, the patient with muscle damage can hardly reach the training standard as required at one time. Rehabilitation training confidence and training motivation of trained patients may also be frustrated if the system feedback always gives a negative assessment of failure to meet standards. The current electromyographic biofeedback rehabilitation training therapy is carried out by a medical surface electromyographic signal detection method. Its design is disease and non-disease as the demarcation point, and is not completely suitable for the rehabilitation training medical treatment aiming at the disease to non-disease process, and it lacks the training selection of the transition period.
The above prior art techniques have their respective disadvantages, although they have their respective advantages. In terms of the whole technologies, the biggest defects of the technologies are that the technologies are independently used, a whole with a synergistic effect cannot be formed, and the advantages of all the families are gathered, and the disadvantages of all the families are eliminated.

Detailed Description
The invention builds a rehabilitation training system with better individual pertinence, interestingness and training effect by utilizing a virtual reality technology, a surface myoelectricity feedback technology, a database processing center, a controllable training platform and/or a pain and/or pulse monitoring system. The virtual reality technology enables the rehabilitation training system to realize the interaction between training actions and a virtual environment. The virtual environment can make people generate a feeling of being personally on the scene, thereby realizing multi-sense stimulation. The surface electromyographic feedback can help to establish a system for evaluating symptoms, illness states and exercise effects, data recorded in real time can be visually fed back to a patient on site, the training posture and/or strength of the patient can be adjusted conveniently in real time, kinematics tracking and evaluation can be carried out in real time, and the purpose of accurate rehabilitation aiming at personal traits or specific muscles or muscle groups is achieved. The controllable training platform performs balancing, tilting and twisting actions under the instruction of the data processing center, so that the patient is forced to perform semi-active and semi-passive guiding activities according to the virtual game.
The surface electromyography feedback technology enables the rehabilitation training system to obtain timely feedback of the disease condition (muscle damage degree) and the training effect of the patient. The data processing center compares the information initially transmitted by the surface myoelectric system with a threshold value of a disease database prestored in the data processing center to determine the disease of a patient, so as to recommend a virtual reality game suitable for the disease, and compares the information with a threshold value of a disease condition database prestored in the data processing center to evaluate and determine the muscle damage grade, and the muscle damage grade is used as a difficulty starting baseline of rehabilitation training. During the rehabilitation training process, the data processing center compares the signals transmitted by the pain and/or pulse monitoring system in real time with the prestored pain and pulse threshold values periodically, and adjusts the rehabilitation training intensity and/or changes the virtual reality game. The data processing center transmits the disease condition and/or disease condition grade evaluation result to the virtual reality scene interactive training system, and transmits the disease condition and/or pain/pulse evaluation result to a controllable training platform; the virtual reality scene interactive training system selects a virtual reality game with proper recommended symptoms and proper training intensity according to the evaluation result of the data processing center. If there are multiple virtual reality programs to choose from, the trainee can choose according to his own interests. The controllable training platform correspondingly adjusts the inclination angle, the torsion amplitude and the like of the platform according to the muscle damage grade and/or the pain/pulse evaluation result of the data processing center so as to increase or weaken the strength of rehabilitation training. The pain and/or pulse monitoring system collects a trainee's on-training muscle pain index and/or pulse beat index. Muscle pain is often manifested as increased sweating and accelerated heartbeat, so collecting sweat exudation and/or pulse beat at a specific location of the trainee can determine the muscle pain status of the trainee while exercising. The pain and/or pulse monitoring system transmits muscle pain signals and/or pulse beat signals of a patient to the data processing center, the data processing center compares the signals with pre-stored muscle pain and/or pulse beat threshold values to evaluate whether the current rehabilitation training intensity is suitable, and if the intensity is too strong or too weak, the data processing center instructs the controllable motion platform to adjust the posture of the controllable motion platform. In addition, pulse monitoring is also a necessary measure to prevent motion accidents.
