Not Applicable

Completed

• Conditions: Bell Palsy
• Interventions: Other: MIME THERAPY; Other: ACTION OBSERVATION THERAPY

• Registration Number: NCT06308250
• Lead Sponsor: Riphah International University

Brief Summary

The aim of this study is to determine comparative effects of mime therapy and action observation therapy on facial symmetry and quality of life in Bell's palsy. Bell's palsy is characterized as an abrupt paralysis of the peripheral facial nerve, typically without a known cause. Mime Therapy is a performing technique that helps patients regain the ability to use their face muscles. Action observation therapy is novel rehabilitation approach exploiting this mirror mechanism.

Detailed Description

This randomized clinical trial will be conducted at Sir Ganga Ram Hospital in 7 months. 62 participants with Bell's palsy will be included as per sample size calculation through convenience sampling technique. Participants which meet inclusion criteria will be randomly allocated using online randomization tool into two groups. Group A will receive Mime therapy for 30 minutes with short resting interval and Group B will receive action observation therapy for 30 minutes. Each group will receive treatment session of 5 days per week for 6 weeks.

Facial symmetry will be measured using the 13-item Sunny Brook facial Grading System, Facial disability index will be used to assess the quality of life and The House-Brackmann Facial Nerve Grading System will be used to characterize the degree of facial paralysis. The data will be analyzed using SPSS version 24 for Windows software.

Arm && Interventions

Group	Intervention	Description
GROUP A ( MIME THERAPY)	MIME THERAPY	Group A will receive mime therapy of 30 minutes with short resting intervals. Treatment will be given 5 times per week for 6 weeks. Mime therapy consist of: 1. Self massage of 10 minutes, 2. Breathing and relaxation exercises of 5 minutes, 3. Articulation of 5 minutes and 4. Facial expression exercises of 10 minutes.
GROUP B (ACTION OBSERVATION THERAPY)	ACTION OBSERVATION THERAPY	Group B will receive action observation therapy of 30 minutes with short resting interval. The treatment will be given 5 times per week for 6 weeks. During the presentation of a video clip, patients sit relaxed in front of the computer screen while observing it. After observing a motor act for 3 min (observation phase) patients are required to imitate what they observed for 2 min (execution phase).

Primary Outcome Measures

Name	Time	Method
Sunny Brook Facial Grading System	6th week	The system includes three components: resting symmetry, the symmetry of voluntary movements, and synkinesis. A composite facial symmetry score is calculated as \[4 × symmetry of voluntary movement - 5 × resting asymmetry + 1 × synkinesis\] with 100 representing normal facial symmetry.
Facial Disability Index	6th week	it is used to assess the quality of life in patients with bell's palsy. It also helps to measure the difficulties of the face in activities of daily living. It represents the relationship between impairments, disability, and psychosocial status and also focuses on the disability of individuals with disorders of the facial motor system. The individual subscales are scored out of a total of 100 where the highest score is the best result.
