Wearable static tremor electronic suppression device based on antagonistic principle

Abstract

The invention discloses a wearable static tremor electronic suppression device based on an antagonistic principle. The wearable static tremor electronic suppression device comprises an eagle eye type electromyographic signal detection three-electrode, an electromyographic signal amplifying and processing unit, a functional electrical stimulation signal generating unit, a muscle functional electrical stimulation electrode pair and an adhesive tape, wherein the eagle eye type electromyographic signal detection three-electrode and the muscle functional electrical stimulation electrode pair are fixed on the back surface of the tape; the electromyographic signal amplifying and processing unit and the functional electrical stimulation signal generating unit are fixed on the front surface of the tape; the eagle eye type electromyographic signal detection three-electrode is used for detecting an active muscle motor nerve action potential signal causing muscle tremor, amplifying, processing and performing pattern recognition on the active muscle motor nerve action potential signal, and then sending the active muscle motor nerve action potential signal into the functional electrical stimulation signal generating unit to generate a functional electrical stimulation signal; and the functional electrical stimulation signal is applied to the muscle functional electrical stimulation electrode positioned on the surface of antagonistic muscle to stimulate the antagonistic muscle to perform limb action opposite to the direction of active muscle, so that the effects of offsetting the active muscle and eliminating limb tremor are achieved.

Description

technical field [0001] The invention belongs to the cross field of rehabilitation medicine and electronic science, and relates to a wearable static tremor electronic suppression device based on antagonism principle. Background technique [0002] One of the symptoms of patients with Parkinson's disease is resting tremor, that is, the hands, upper and lower limbs, and even the whole body produce rhythmic shaking with a frequency of 4-6 Hz when they are still, which is aggravated when they are tense, and the tremor is weakened during activities such as walking and disappears during sleep. . The cause of rest tremor is mainly due to the imbalance of the two major transmitter systems of the nervous system, namely the acetylcholine system and the dopamine system. Tremor brings physical inconvenience, psychological burden, and reduced quality of life to patients. At present, the main method of treating rest tremor is to use some anti-Parkinson drugs. However, it is generally con...
