Recovery following facial nerve palsy is variable. Physiotherapists try to restore function in patients with Bell's palsy. The choice of treatment modality depends on the stage of the condition. Although limited evidence exists for The use of electrical stimulation in the acute stage of Bell's palsy, sonic physiotherapists in South Africa have been applying this modality. This study examined the effects of electrical stimulation on functional recovery from Bell's palsy using the Facial Disability Index, a tool that documents recovery from the patients' perspective. A two group pre-test post-test experimental design comprising of 16 patients with Bell's palsy of less than 30 days duration was utilized. Patients with a clinical diagnosis of Bell's Palsy were systematically allocated to the control and experimental groups. Patients (n = 16) were pre-tested and post-tested using the Facial Disability Index. Both groups were treated with heat, massage, exercises and given a home program. The experimental group also received electrical stimulation. The FDI of the control group improved between 17.8% and 95.4% with a mean of 52.8%. The improvement in the experimental group ranged between 14.8% and 126% with a mean of 49.8%. Certain clinical residuals persisted in a mild form in both groups on discharge from the study The effects of electrical stimulation as used in this study during the acute phase of Bell's palsy quantified as the FDI was clinically but not statistically significant. A larger sample size, longer stimulation time or both should be investigated.
