Problems solved by technology

[0002] Traditional spinal cord stimulators use motor neurons as the activation objects, and the actions controlled by neurons are relatively single. Therefore, to complete a relatively complex coordinated action, multiple electrodes are required to perform FES in a certain sequence.

Abstract

The invention relates to a double-hind-limb gait regulation and control system for stimulating a rat CPG site through a single-port electrode. The system comprises an upper computer, a stimulator, a biological stimulation electrode, a reference electrode, a knee joint angle collector, an impedance measuring circuit and a relay switching circuit. According to the system, a specific CPG site is stimulated through positive and negative voltage pulse stimulation signals, knee joint angle data are tracked and captured through a sensor, a mapping relation model of signals and gaits is established, and closed-loop regulation is formed through gait joint angle information fed back to a processor in real time. Training parameters are set according to the mapping relation model to carry out gait training on the SCI rat. Compared with a normal gait, regulation and control can be carried out within a certain range of the normal gait.

Description

technical field [0001] The invention relates to an intelligent control electronic system in the field of rehabilitation engineering and a control method thereof, in particular, a single-port stimulating electrode is used to regulate the alternate movement of a rat's hind limbs through positive and negative voltage pulse signals. Background technique [0002] Traditional spinal cord stimulators use motor neurons as the activation objects, and the actions controlled by neurons are relatively single. Therefore, to complete a relatively complex coordinated action, multiple electrodes are required to perform FES in a certain sequence. If the neuron network can be used as the activation object, the number of stimulating electrodes can be effectively reduced and the timing can be simplified. In vertebrates, the central pattern generator (CPG) located in the spinal cord is a network of neurons that generates rhythmic control outputs capable of combining autonomously generated signal...
