Mirror Therapy vs Mime Therapy in Bell's Palsy

July 16, 2026 updated by: Kashifa Noreen, University of Lahore

Comparative Effects of Mirror Book Therapy and Mime Therapy in Patients With Bell's Palsy

This randomized controlled trial aims to compare the effectiveness of mirror book therapy and mime therapy in patients with Bell's palsy. The study evaluates improvements in facial symmetry, functional disability, and patient satisfaction following structured rehabilitation interventions.

Conditions

Intervention / Treatment

Detailed Description

Bell's palsy is a peripheral facial nerve paralysis that results in facial asymmetry and functional impairment. Rehabilitation approaches such as mime therapy and mirror therapy are widely used. Mirror therapy incorporates visual feedback and motor relearning principles, which may enhance neuromuscular recovery . Mime therapy focuses on facial exercises, symmetry training, and functional retraining.

Participants will be randomly allocated into two groups:

Mirror Book Therapy Group Mime Therapy Group

Both groups will receive structured treatment protocols over a defined period. Outcome measures will be assessed at baseline and post-intervention to determine comparative effectiveness.
