Paralyzed limb movement control method based on acupuncture point functional electrical stimulation

Abstract

The invention discloses a paralyzed limb movement control method based on acupuncture point functional electrical stimulation. Body surface myoelectrical signals when healthy limbs move are collected by using a body surface exploring electrode array, signal processing such as amplification and filtering is carried out on the collected myoelectrical signals through a signal processing circuit, then the myoelectrical signals are transmitted to a stimulating signal generating circuit through a communication channel to generate stimulation signals, and lastly, the stimulation signals are applied to a needle-shaped or concentric circle stimulating electrode array of an assigned acupuncture point of the paralyzed limb to achieve the movement of the paralyzed limb. According to the paralyzed limb movement control method based on the acupuncture point functional electrical stimulation, the mode of electric needle stimulation is adopted, body surface stimulation is changed into body internal stimulation on meridian points, an acupuncture therapy is inherited and developed, the advantages of being good in selectivity and high in sensitivity are achieved, and the paralyzed limb movement control method based on the acupuncture point functional electrical stimulation can be applied to sites such as control over movements of the paralyzed patient limbs caused by various injuries and diseases.

Description

technical field [0001] The invention belongs to the cross field of traditional medicine, rehabilitation medicine and electronic science, relates to a method for controlling the movement of paralyzed limbs, in particular to a method for controlling the movement of paralyzed limbs based on acupoint stimulation. Background technique [0002] For a long time, acupuncture has been used in the functional rehabilitation of paralyzed limbs. Acupuncture is mainly used to achieve the effect of limb rehabilitation through lifting, pulling, twisting, turning and other manipulations to determine the time of treatment. Since the 1950s, people have introduced electroacupuncture technology as a supplement to acupuncture methods, forming a series of electroacupuncture instruments, which are widely used in clinical practice. [0003] Taking electroacupuncture as an example, it uses artificially designed electric pulse sequences (electrical pulses with different frequencies, amplitudes, and d...

Problems solved by technology

The advantage of this method is that neither collecting signals nor applying stimulation signals is non-invasive, but the disadvantage is that the large-area stimulating electrodes attached to the body surface have poor selectivity and low sensitivity (usually a voltage above 20V is required to stimulate paralysis. movement of limbs), difficulty controlling fine motor movements of paralyzed limbs
