About this study
Official title: 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.
Read the 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.
- Conditions
- Bell's Palsy
- Being tested
- Mirror Book Therapy, Mime Therapy

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mirror Book TherapyBehavioural
A rehabilitation technique using mirror visual feedback to improve facial muscle coordination and symmetry through repeated guided exercises.
Mime TherapyBehavioural
A structured facial exercise program aimed at improving muscle control, coordination, and facial expressions.
| Study group | Role | What they receive |
|---|---|---|
| Mirror Book Therapy Group | Experimental | Participants receive mirror-based facial rehabilitation using a mirror book to enhance visual feedback and motor relearning. Receives: Behavioral: Mirror Book Therapy |
| Mime Therapy Group | Active comparator | Participants receive mime therapy focusing on facial muscle exercises, expressions, and symmetry training. Receives: Behavioral: Mime Therapy |
