Abstract: Objective To investigate the effect of electromyographic biofeedback therapy on upper extremity function in children with cerebral palsy(CP).Methods 20 CP children were randomly divided into the treatment group and control group with 10 cases in each group.All children of two groups were treated with Bobath therapy and regularly training of activities of daily living(ADL),physical therapy and occupational therapy,while those of the treatment group were given electromyographic biofeedback therapy with EMG-electrical stimulation.The active range of motion(AROM)of wrist dorsiflexion was evaluated and upper extremity function was assessed by Fugl-Meyer Assessment(FMA).Results The upper extremity function of all children in two groups improved and the effect of the children of the treatment group were superior to those of the control group(P<0.05).Conclusion The electromyographic biofeedback therapy with EMG-electrical stimulation can improve the upper extremity function of CP children.
