A Comparative Study to Assess the Effects of Electrical Stimulation in Recent Onset Bell’s Palsy

Key Points

Both groups showed significant improvement in facial function after treatment, but without added benefit from electrical stimulation.
Statistical analysis confirmed P < 0.001 for improvements in facial nerve scores across follow-ups, despite no differences between groups.
Participants received pharmacological therapy and facial exercises, with one group also undergoing electrical stimulation for three weeks.
The findings suggest that conventional rehabilitative measures suffice for recovery in recent onset Bell's palsy, limiting the role of electrical stimulation.

Abstract

Abstract Background: Electrical stimulation (ES) of facial muscles during the early days of Bell’s palsy always remains controversial. Hence, this study was done to assess the effects of ES in recent onset Bell’s palsy ( 0.05 in all parameters during all the follow-ups). Conclusion: ES did not provide any extra benefit to patients suffering from recent onset idiopathic Bell’s palsy over the conventional pharmacological and non-pharmacological rehabilitative measures.
