Multi-channel functional electrical stimulation output control method for lower limb rehabilitation of myoelectric modulation

Abstract

The invention relates to a multi-channel functional electrical stimulation output control method for lower limb rehabilitation of myoelectric modulation. Electromyographic signals of two pairs of antagonist muscles for controlling knee and ankle joint movement when a healthy person walks normally are collected offline, and the processed ectromyographic signals modulate multi-channel electrical stimulation output intensity enveloping lines to stimulate the two pairs of the antagonist muscles in the lower limbs of a patient. The method is applied to the lower limb rehabilitation training processof the apoplexy patient, can not only prevent muscle spasm, but also achieve multi-joint coordinated movement similar to normal people, and can achieve the rehabilitation training of a lower limb walking function, thereby achieving the purpose of lower limb functional reconstruction.

Description

technical field [0001] The invention relates to a multi-channel functional electrical stimulation output control method for lower limb rehabilitation modulated by myoelectricity. Background technique [0002] In recent years, the incidence of paralysis caused by spinal cord injury and stroke and other cerebrovascular diseases has shown a significant upward trend, which not only brings a greater burden to individuals and families, but also becomes an increasingly serious social problem. Limb function training and reconstruction are the key and difficult points in the rehabilitation treatment of hemiplegic patients such as stroke, which is related to the improvement of their daily life ability and quality of life. At present, functional electrical stimulation (FES) is generally considered to be an effective clinical tool in the rehabilitation of lower limbs of hemiplegic patients. Functional electrical stimulation mainly stimulates the injured muscles or muscle groups of the ...

AI Technical Summary

Problems solved by technology

Separate control of periodic electrical stimulation for each joint does not use electrical stimulation for coordinated movement training of the lower limb joints, and the independent movement of each joint cannot achieve the function of the lower limbs

Moreover, this rehabilitation method of individual joint training does not give patients normal sensory input signals to the brain, nor does it produce normal control output signals similar to those of the brain. From the perspective of neurorehabilitation and motor function reconstruction theory, it is impossible to restore patients to normal and similar health. Human lower limb motor function
