About

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.

Full 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.

62 participants in 2 patient groups

GROUP A ( MIME THERAPY)

Experimental group

Description:

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.

Treatment:

Other: MIME THERAPY

GROUP B (ACTION OBSERVATION THERAPY)

Experimental group

Description:

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
