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.

Outcome Measures

Primary Outcomes (2)

• Sunny Brook Facial Grading System

  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.

  6th week

• Facial Disability Index

  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.

Study Arms (2)

GROUP A ( MIME THERAPY)

EXPERIMENTAL

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.

Other: MIME THERAPY

GROUP B (ACTION OBSERVATION THERAPY)

EXPERIMENTAL

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).

Other: ACTION OBSERVATION THERAPY

Interventions

MIME THERAPY 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 A ( MIME THERAPY)

ACTION OBSERVATION THERAPY 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).

GROUP B (ACTION OBSERVATION THERAPY)
