Role of Neuromuscular Electrical Stimulation in Bell’s Palsy: A Case Study of Three Patients

Abstract

Bell's palsy is an idiopathic, unilateral facial paralysis, caused by a malfunction anywhere along the facial nerve's peripheral portion, from the pons distally. Bell's palsy is treated by removing the cause of nerve injury, strengthening the face muscles, and restoring facial function. Physical therapy in the form of neuromuscular electrical stimulation (NMES), massage and facial exercises is used as adjuvant to hasten recovery. The aim of this study is to access of role of neuromuscular electrical stimulation (NMES) treatment in Bell’s palsy patients. A detailed neurological assessment of three patients was done with emphasis on facial muscles and severity of paralysis was graded according to House Brackmann scale (HBS). Conventional physiotherapy was given in the form of electrical stimulation, facial massage, exercises and functional re-education on a daily basis. Patients were assessed at weekly and 1months after the treatment. They experienced complete recovery within 1month follow-up, no recurrence was observed and all patients have normal facial movement. Physiotherapy in the form of NMES and facial exercises has a effective role in the early management of Bell’s palsy.
