Abstract

The invention belongs to the medical apparatus and instrument field and provides a closed-loop brain controlled functional electrical stimulation system. The closed-loop brain controlled functional electrical stimulation system is characterized in that the system includes a cerebral motor cortex signal acquisition module, an information control module, a stimulator, a body movement acquisition module and a frontal lobe signal acquisition module, wherein the information control module includes a signal pre-processing sub-module, a pattern recognition module and a command control sub-module. The closed-loop brain controlled functional electrical stimulation system provided by the technical schemes of the invention is advantageous in that the closed-loop brain controlled functional electrical stimulation system can ensure the accuracy of limb movement the identification and improve the rehabilitation treatment effect of patients with paralysis.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a closed-loop brain-controlled functional electrical stimulation system. Background technique [0002] With the continuous increase of accidental injuries such as traffic accidents and falls, the number of spinal cord injuries continues to rise. It is estimated that there are 2.5 million spinal cord injury patients in the world, and nearly 130,000 new cases occur every year. Functional electrical stimulation is a main clinical treatment method used to restore nerve dysfunction caused by spinal injuries. It stimulates the limbs of patients through electric current, so that the limbs that have lost motor function can complete corresponding actions. However, at present, this method can only treat patients through a pre-set electrical stimulation process. If the treatment time is too long, it may cause discomfort to the patient and even muscle strain, and the patient cannot complete...
