Effects of Myoelectric Biofeedback on Upper Limb Function in Post-stroke Patients

On the basis of myoelectric biofeedback treatment in the control group, the control group was trained alternately in each muscle group (triangle muscle, triceps brachii muscle group and forearm extensor muscle group). For example,After disinfection of the triangular, triceps and extensor muscles of the patient, the feedback electrode was attached to the area. The stimulation frequency was set at 50 Hz and the stimulation pulse width was set at 200 μs.During treatment, the patient is instructed to listen carefully to the device's password, drive the affected limb according to the specific password, and then perform tension and relaxation training.For each muscle group, the training time of each muscle group is about 0.5 h, 1 / d.In the later stage of treatment, the training intensity can be increased appropriately, so that the patient can carry out weight lifting during the feedback treatment, and listen to the password issued by the device to carry out muscle strength exercise.
