Description

technical field [0001] The invention relates to the field of functional electrical stimulation equipment, in particular to a high-voltage drive circuit system for functional electrical stimulation. Background technique [0002] Functional electrical stimulation technology is a rehabilitation technology that uses pulse currents that the human body can adapt to stimulate muscles that have lost or have imperfect nerve control, and controls the muscles to achieve periodic movement of the lower limbs, so as to replace or correct limbs and organs that have been damaged. Lost functionality. Functional electrical stimulation technology not only stimulates the neuromuscular, but also stimulates the conduction nerves, coupled with the repetitive motion pattern information, which is transmitted to the central nervous system, forming excitatory traces in the cortex, and gradually restoring the original motor function. The main clinical applications of this technology include reversing ...
