Embodiment 1

[0043] Such as figure 1 As shown, the muscle group dynamic electric stimulation integrated control system of the present embodiment includes a pressure sensor and a dynamic electric stimulator, and the signal output terminal of the pressure sensor is connected with the signal input end of the dynamic electric stimulator; the dynamic electric stimulator has multiple stimulators Each stimulation channel has a pair of stimulation electrodes that can be attached to the skin surface; the dynamic electric stimulator also has a stimulation parameter modulation unit whose control terminal is connected to the controlled terminal of each stimulation channel. The stimulation parameters include stimulation waveform, stimulation intensity, stimulation Frequency, Stimulus Width, Waiting Time Before Stimulation, and Stimulation Duration.

[0044] The stimulation parameter modulation unit has several modulator groups, and the control end of each modulator group is connected to the controlled ...

Embodiment 2

[0047] Such as figure 2 As shown, the muscle group dynamic electrical stimulation integrated control method of this embodiment adopts the muscle group dynamic electrical stimulation integrated control system of Embodiment 1; the method includes:

[0048] Front step, U1. Divide the walking cycle of the unilateral lower limb into seven stages in sequence: the foot-flat period, the lower limb standing period, the toe-off period, the early swing period, the mid-swing period, the final swing period, and the heel strike period. Each stage has a start point and an end point, the start point of each stage coincides with the end point of the previous stage, and the end point of each stage coincides with the start point of the next stage.

[0049] U2. Through the walking detection and analysis of several normal people, we can know: the duration of each stage of the walking cycle and its proportion in the entire walking cycle, the specific lower limb muscle groups participating in the c...

Abstract

The invention relates to a dynamic electrostimulation integrated control system and method of muscle groups. The system comprises a pressure sensor and a dynamic electrostimulation instrument; the dynamic electrostimulation instrument includes multiple stimulation channels, and each stimulation channel includes a pair of stimulation electrodes that can be applied to the surface of skin; the dynamic electrostimulation instrument also includes a stimulation parameter modulation unit, and stimulation parameters include stimulation waveform, stimulation intensity, stimulation frequency, stimulation wave width, waiting time before stimulation and stimulation continuous time. The method comprises that different parts are worn or fixed, the stimulation parameters are set, stimulation is started, and stimulation is completed. According to the invention, coordinated electrostimualtion can be realized for the multiple muscle groups of lower limbs, and patients who have a hemiplegic gait due to partially insufficient muscle force caused by diseases can be helped to make complete walking motions.

Description

technical field [0001] The invention relates to an integrated control system and method for dynamic electrical stimulation of muscle groups, which is especially suitable for treating body motor dysfunction in stroke patients and patients with other brain injury-related diseases, and belongs to the technical field of sports rehabilitation treatment. Background technique [0002] As far as the applicant knows, electrical stimulation can be effectively used to treat movement disorders in stroke patients and body dysfunction caused by many diseases (mainly brain injuries). The background and principle of this therapy are basically as follows: when normal people are walking, the nervous system adjusts the contraction or relaxation of the relevant muscle groups of the lower limbs to drive the legs to step alternately, and pushes the body forward with the help of ground friction; for hemiplegia and stroke patients, The connection between the cranial nerve and some muscles is damage...
