Abstract

The invention provides an electrical stimulation system with a fatigue evaluation function. The electrical stimulation system comprises a multiplexing electrode slice, an EIM excitation current module, an FES stimulation current module, a control module and an acquisition module, and the multiplexing electrode slice is connected with the EIM excitation current module, the FES stimulation current module and the acquisition module respectively. The EIM excitation current module is used for generating an excitation current signal; the FES stimulation current module is used for generating FES stimulation signals. The electrical stimulation system has the advantages of being simple in feedback control process, stable in measurement process during resting, good in robustness and not prone to being disturbed by external factors, the amplitude of the feedback signals is large, the frequency is controllable, and preprocessing is simple. According to the scheme, on the basis of the electrical stimulation system, an EIM detection link is added, the stimulated local muscle fatigue state is fed back to the system in real time, excessive treatment caused by muscle fatigue is avoided, and the rehabilitation effect is improved.

Description

technical field [0001] The invention relates to the field of electric stimulation devices, in particular to an electric stimulation system with fatigue evaluation function. Background technique [0002] Chinese patent (application number: 201510313665.2) proposes a functional electrical stimulation closed-loop control system and method based on electromyographic signal feedback, which completes the pulse number of electrical stimulation by calculating the absolute average amplitude of the electromyographic signal of the stimulated object. The closed-loop control adjustment; the invention improves the control precision of the closed-loop functional electrical stimulation system, and realizes the adaptive control of the functional electrical stimulation of the myoelectric signal feedback. Chinese patent (application number: 201710905850.X) proposes a closed-loop electrical stimulation system based on electromyographic biofeedback, which can detect the patient's electromyograph...
