Abstract: Objective To investigate the effect of EMG-electrical stimulation on upper extremity function in patients with hemiplegia after stroke.Methods52 stroke patients with hemiplegia were randomly divided into the EMG-electrical stimulation group (27 cases) and control group (25 cases). All patients of two groups were treated with routine therapy and regularly physical therapy and occupational therapy, while those of the EMG-electrical stimulation group were given EMG-electrical stimulation training. The active range of motion (AROM) of wrist dorsiflexion was evaluated and upper extremity function was assessed by Fugl-Meyer Assessment (FMA) pre-treatment and 2 months after treatment.ResultsThe upper extremity function of all patients in two groups improved and the patients of the EMG-electrical stimulation group were superior to those of the control group ( P<0.05). The AROM and FMA scores of the patients in the EMG-electrical stimulation group were significantly superior to that of the patients in the control group ( P<0.05).ConclusionThe EMG-electrical stimulation can improve the upper extremity function of hemiplegic patients after stoke.
