Artificial kinetic nerve system reconstructing process for paraplegic walking

Abstract

The present invention belongs to the field of rehabilitation medicine, and relates to kinetic nerve system reconstructing process. The subjective sports consciousness information of the paraplegia patient is led out via electrocerebral signal to control the autonomous motion state of the lower limb. Each cycle includes the following steps: acquiring the electrocerebral signal with the multiple lead electrodes in the head of the paraplegia patient; treating the signal, digitizing and inputting to the brain-computer interface controller; spectral analysis and mode recognition on the electrocerebral signal; judging whether to have walking intention and ending the cycle if no; or else, generating functional electric stimulation switch control signal and transmitting to the functional electric stimulation generator; and driving the multiple lead electrodes in the lower limb. The present invention is suitable for the rehabilitation exercise of the paraplegia patient as well as hemiplegia patient.

Description

technical field [0001] The invention belongs to the field of rehabilitation biomedicine and relates to an artificial motor nervous system reconstruction method. Background technique [0002] Paraplegia is a severe disability of the lower limbs caused by spinal cord injury, and its incidence has shown a significant upward trend in recent years. Since the spinal cord is in charge of information transmission between the brain and other parts of the human body (especially the limbs), its damage will directly lead to nervous system disorders below the wound, resulting in paralysis of the corresponding limbs. In addition, its regenerative ability is quite weak, and clinical treatment methods are very limited. Functional Electrical Stimulation (FES) technology is generally considered to be an effective clinical tool in the restoration of walking ability of paraplegic patients. FES technology is to install a stimulation device at the paralyzed limb, and stimulate the muscle contrac...

AI Technical Summary

Problems solved by technology

But so far, the motor nerves reconstructed by FES technology are limited to the peripheral motor nerves that drive the leg muscles. At present, there is no central nerve connected to the patient's brain, and it cannot be regarded as an independent, autonomous and complete motor nervous system.

Therefore, the existing FES control signal can only be given passively by the outside world, and its motor nerve reconstruction control mode cannot express the patient's subjective motor consciousness, so it has fatal weaknesses such as poor adaptability, easy to be disturbed, and difficult to learn and master, which restricts FES The motor nerve reconstruction effect of the technology has become a bottleneck problem to be solved in the clinical promotion and application of rehabilitation
