Muscle electricity biofeedback instrument possessing range and sensitivity automatic adjusting device

Abstract

A myoelectric biofeedback instrument with an automatic adjustment device for range and sensitivity. According to the characteristic that the smaller the myoelectric amplitude is during the feedback training process, the higher the sensitivity of the myoelectric feedback is required, a multi-level display of myoelectric amplitude is proposed. The difference between the corresponding myoelectric amplitude values ​​between adjacent levels is not equal, and the program increases step by step. In this patent solution, the smaller the EMG amplitude value is, the greater the display sensitivity is, and the entire EMG value can be displayed within the full display range. There is no need for the trainee to adjust the EMG signal sensitivity and range during the training process. It is more conducive to the trainee to concentrate on relaxing training during the training process without interference and ensure the quality of training.

Description

technical field [0001] The invention relates to the field of medical equipment, more specifically, to a myoelectric biofeedback instrument with an automatic adjustment device for range and sensitivity. Background technique [0002] Biofeedback therapy refers to the use of modern instruments to process the physiological indicators of the human body, such as heart rate, blood pressure, skin temperature, EEG and myoelectricity, and then display them to patients in visual or auditory ways—that is, feedback of information, so that Through training and recognizing these information, patients learn to consciously control their own physiological activities, so as to achieve the purpose of adjusting body functions, preventing and treating diseases. [0003] EMG biofeedback technology is a commonly used biofeedback technology. Generally speaking, the degree of muscle tension is positively correlated with the degree of emotional anxiety, and the degree of psychological and physical re...

AI Technical Summary

Problems solved by technology

Since the patient is in a state of gradual relaxation at this time, if you adjust the sensitivity of the instrument yourself, the relaxed muscles will become tense again to varying degrees, which will affect the training effect; if the sensitivity is adjusted by other people, it will also bring corresponding problems. , so that the training cannot be carried out continuously
