PURPOSE: Upper Motor Neuron Facial Palsy is common in those who have had a stroke. Electrical stimulation and other available therapeutic options for UMN facial palsy have been the subject of several research papers. The purpose of this study is to see how effective facial retraining exercise using self-monitoring virtual feedback via a mobile application for treating UMN facial palsy. MATERIAL AND METHOD: An experiment was carried out with the help of 82 volunteers. Based on the selection criteria, all of the participants were separated into experimental and control groupsThe experimental group was given electrical stimulation and face retraining exercises with self-monitoring virtual feedback via an android application, whereas the control group was given electrical stimulation and conventional exercises. House-Brackmann facial grading score was measured pre and post to the intervention by a blinded assessor who was unaware about group allotment. RESULT: Comparison of the post-test values of both groups shows that the mann whitney U value = 450 at p value of 0.0003 and median values between the two group (Experimental = 2.000) (Control = 3.000) is greater than the expected. As a result, the study reveals that the experimental group has made a statistically significant improvement. DISCUSSION AND CONCLUSION: This study concluded that electrical stimulation and facial retraining exercises with self-monitoring virtual feedback using android smart phone application showed substantial improvement in facial function, compared to electrical stimulation and conventional exercises with mirror feedback in the treatment of UMN facial palsy.
