Effect of Electromyogram Biofeedback Stimulation on Upper Extremity Function with Acute Stroke Hemiplegia

Objective: To evaluate the effect of electromyogram biofeedback stimulation on upper limb function of acute stroke hemiplegic patients,and explore more effective ways for the rehabilitation of the upper limb motor dysfunction after acute stroke.Methods: 35 acute stroke patients following hemiplegia who with stable vital signs,unconscious barriers were divided into observation group(n=18) and control group(n=17).Two groups were given clinical treatment and conventional rehabilitation training.The observation group patients' hemiplegic upper limb added surface electromyogram biofeedback stimulation training.Brunnstrom's recovery stages,the Fugl-Meyer Assessment(FMA) and electromyography amplitude of wrist dorsiflexion on hemiplegic upper limb were assessed before and 2 months after the treatment.Results: Both groups had significantly higher Brunnstrom's and FMA scores and better electromyography amplitude(P0.05),and the observation group was significantly better than the control group after the treatment(P0.05).Conclusion: In this article,the hemiplegic upper limb motor function of observation group and control group patients were improved after rehabilitation compared with before treatment.It can better improve the upper extremity function of hemiplegic patients after acute stoke that electromyogram biofeedback stimulation training combined with conventional rehabilitation comparing to use PT and OT alone.More significantly,it promoted the motor function recovery and the generation of separatist movement of the hemiplegic upper limb,and provided the electrophysiological basis on the recovery of wrist dorsiflexion muscle strength.In short,on the basis of conventional rehabilitation with EMG bio-feedback therapy,may be more significant in promoting hemiplegia upper limb function of acute stroke patients,and provide a more effective method for the rehabilitation of patients with acute stroke limb movement disorder.
