Effects of Mirror Visual Feedback and Electromyographic Biofeedback on Upper Extremity Function in Hemiplegics after Stroke / 中国康复理论与实践

ABSTRACT

Objective To investigate the effects of mirror visual feedback (MVF) and electromyographic biofeedback (EMGBF) on up-per extremity function in hemiplegic patients after stroke based on task-oriented training. Methods 90 patients with hempiplegia after stroke were randomly divided into control group (n=30), EMGBF group (n=30) and MVF group (n=30). All patients accepted routine rehabilitation and task-oriented training once a day for 8 weeks. The EMGBF group also accepted EMGBF, and the MVF group accepted MVF in addi-tion. They were assessed with Fugl-Meyer Assessment (FMA) and the Upper Extremity Function Test (UEFT), and their integrated electro-myogram (iEMG) of affected upper extremities were recorded before and after treatment. Results All the groups improved in scores of FMA and UEFT, as well as the iEMG after treatment (P<0.05), and ranked as the MVF group, the EMGBF group and the control group from im-proving more to less (P<0.05). Conclusion Mirror visual feedback combined with electromyographic biofeedback may further promote the recovery of upper limb function in patients with hemiplegia after stroke based on task-oriented training.
