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.

Study Groups

GROUP A ( 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 Type: EXPERIMENTAL

MIME THERAPY

Intervention Type: OTHER

Mime therapy consist of:

Self massage: patients will be taught to massage their face and neck daily for about 10 minutes which includes effleurage and kneading of both sides of face.

Breathing exercises: patient will be taught to recognize tension and feel the difference between tension and relaxation in facial musculature for 5 minutes. Expiration exercises will be used to induce relaxation.

Articulation: vowels such as a,e,i,o,u and consonants such as p and b will be used to teach position of the lips for 5 minutes.

Facial expression exercises: forehead wrinkle, smiling, eye closure, frowning, disgust, surprise, anger, sadness will be performed for 10 minutes

GROUP B (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).

Group Type: EXPERIMENTAL

ACTION OBSERVATION THERAPY

Intervention Type: OTHER

Function of each of the muscle is observed for 3 minutes and then executed for 2 minutes.

Frontalis (Raising eyebrows and forehead wrinkling). Corrugator Supercili (Moving the eyebrow down and inward toward the nose and inner eye).

Orbicularis oculi (Closing the eyelids). Buccinator (Blowing air in and out of the mouth). Zygomaticus major (Smiling). Orbicularis oris (Lip pursing or puckering).
