| Objective:To explore the effect of electromyographic biofeedback therapy on facial functional recovery of Bell's palsy.Method:Sixty-four patients with Bell's palsy were randomly and equally divided into control group and observation group.The observation group received medication,rehabilitation and electromyographic biofeedback therapy,while the control group received no electromyographic biofeedback therapy.They were assessed with House-Brackman (H-B) grading,manual muscle test (MMT),simply facial nerve function score and healing duration before and 20 days after treatment.Results:After treatment for 20 days,the H-B grades,muscle strength and scores on facial nerve function in the two groups were significantly increased as compared with those before treatment (P<0.01),more significantly in the observation group than in the control group (P<0.05,or 0.01).The average healing duration in the observation group was obviously shorter than in the control group (P<0.01).Conclusion:Electromyographic biofeedback therapy can significantly enhance the facial muscle of patients with Bell's palsy,therefore improving autonomous movement and shortening the course of treatment. |
