Dr. Nilesh Andhare | Dr. Ujwal Yeole | Urvashi Ghodasara

Abstract: Background: Unilateral paralysis of the facial muscles and ssynkinesis is the cause of bells palsy. The conversion of myoelectric signals in the muscle into visual and auditory signals is created by new feedback systems by using EMG biofeedback technique of retraining muscle. Aim and objectives: To find out the effects of EMG biofeedback training on facial muscle strength and motor nerve latency in bells palsy. Methodology: 12 participants were selected according to inclusion and exclusion criteria and consent was taken.3 muscles selected, for each muscle 120 contractions were given in 3 sets i. e.40 contractions in each set. Evaluation was done for facial muscle strength with the help of house brackmann scale and motor nerve latency with the help of nerve conduction unit. Treatment was given for 2 weeks with included 3 sessions per week. And post treatment house brackmann score and latency was found. Results: The difference in house brackmann scale was 0.667 (p-0.0015). The difference in latency of frontalis was 0.124 (p- 0.0149), orbicularis oculi was 0.108 (p- 0.0299) and orbicularis oris was 0.1382 (p- 0.0552). Conclusion: In this study we concluded that there is effect of EMG biofeedback training on facial muscle strength and motor nerve latency in bells palsy.
