Multi-triggering-mode intelligent electrical stimulation hand trainer and method

Abstract

The invention relates to a multi-triggering-mode intelligent electrical stimulation hand trainer and a method. The trainer comprises an electromyographic signal collecting module, a curvature collecting module, a touch screen module, a host control module, an electric pulse generation module and the like. The method includes the steps of the electromyographic triggering mode, wherein electric signals generated by uninjured side forearm muscles of a patient according to the hand grabbing actions are collected by the electromyographic signal collecting module and transmitted to the host controlmodule; the curvature triggering mode, wherein the curvature information of the uninjured side hand grabbing actions of the patient is collected by the curvature collecting module in real time and transmitted to the host control module; the touch screen triggering mode, wherein different muscle groups of affected side forearm of the patient are selected according to the demands of the patient to be stimulated, signals are transmitted to the host control module, and the electric pulse generation module is triggered to generate different electric pulses to stimulate the muscle groups of musculusflexor digitorum sublimes, musculi flexor pollicis longus, extensor digitorum muscles and extensor pollicis brevis muscles of the affected side forearm of the patient after the real-time treatment ofthe host control module so that the grabbing actions the same as those of an uninjured side hand can be completed by an affected side hand of the patient.

Description

technical field [0001] The invention relates to a stroke rehabilitation training device, in particular to a multi-trigger intelligent electric stimulation hand training device. Background technique [0002] Stroke is a condition in which brain damage occurs due to rupture of a blood vessel in the brain or blockage of a blood vessel that prevents blood from returning. It includes hemorrhagic stroke and ischemic stroke. Among the many sequelae of stroke, hand dysfunction is one of the most common obstacles in patients with hemiplegia after stroke, which seriously affects patients' daily life activities and brings a heavy burden to patients' families and society. [0003] With the acceleration of the population aging trend, the number of patients with hemiplegia is increasing year by year, but rehabilitation physicians and rehabilitation resources are very scarce. Rehabilitation therapies that are often used in clinical practice include exercise therapy, occupational therapy, ...

AI Technical Summary

Problems solved by technology

Rehabilitation therapies that are often used in clinical practice include exercise therapy, occupational therapy, and physical factor therapy, all of which require the guidance and assistance of multiple professional rehabilitation physicians, and the equipment is bulky, time-consuming and laborious to wear, and inconvenient to use, which seriously affects the treatment efficiency and reduces patients' participation in treatment. enthusiasm, it is difficult to meet user needs
