Abstract

The invention provides a myoelectric signal-controlled master-slave wireless functional electric stimulation rehabilitation system in the technical field of rehabilitation medical treatment. The system comprises a master unit and a slave unit, wherein the master unit is connected with a master side to transmit myoelectric information; the master unit is in wireless connection with the slave unit to transmit motion mode information; and the slave unit is connected with a slave side to transmit electrical pulse information. The master unit comprises a plurality of EMG electrode plates, an amplifier, a filter, an encoder and a wireless transmitter; and the slave unit comprises a wireless receiver, a controller, an electrical stimulator and a plurality of FES electrode plates. By using the system, a physical therapist assists a paralyzed patient to do training without physical contact, and a plurality of patients can do rehabilitation trainings following the same physical therapist, so the workload of the physical therapist is greatly lightened; meanwhile, the system can keep the muscle vitality of the patient, prevent muscular atrophy, reduce convulsion and help the patient achieve more ideal rehabilitation effect.

Description

technical field [0001] The invention relates to a system in the field of rehabilitation medical technology, in particular to a master-slave wireless functional electrical stimulation (FES) rehabilitation system controlled by an electromyography (EMG) signal. Background technique [0002] According to the statistics of the World Health Organization, there are about 25-30 million cerebral apoplexy (stroke) patients in the world at present, and there are at least 6 million people in my country, and this number is still on the rise. If you add paralyzed patients caused by other reasons, the number will be even more alarming. For the early rehabilitation of paralyzed patients, exercise therapy is a very important and effective means. At present, the exercise rehabilitation of stroke patients is generally carried out with the assistance of physical therapists, sometimes relying on some simple traditional equipment. In this way, the movement of the patient is carried out passivel...
