Abstract: Background: Bell’s palsy is a facial paralysis of acute onset presumed to be due to non-suppurative inflammation of unknown etiology of facial nerve within its canal above its stylomastoid foramen. Bell’s palsy accounts to be one of the most common cause for unilateral infranuclear facial weakness. Purpose: The purpose of this study was to find out the effect of physical therapy on early prognosis of Bell’s palsy. Methods: An experimental study of 30 participants with the age group of 18-40 years was conducted. Electromyography and nerve conduction velocity was taken on 3rd, 7th and 14th day of physical therapy treatment for all the participants. All the participants received conventional treatment; Electrical stimulation, Facial massage, Facial PNF and specific facial exercises in front of mirror. Interrupted galvanic stimulation will be given on motor points of paralyzed muscles. Conventional treatment was given for 1 hour a day, 6 days a week for 2 weeks. Results: Reading was calculated on 3 different days; co-efficient of variation of frontalis muscle on 3rd,7th and 14th day were 2.234, 1.916 and 1.682 respectively, for orbicularis occuli muscle on 3rd, 7th and 14th day were 1.439, 0.826 and 0.421respectively and for orbicularis oris muscle on 3rd,7th and 14th day were 0.996, 0.929 and 0.875 respectively. And Nerve conduction velocity for 3rd, 7th and 14th day were 8.533 ± 1.961, 6.466 ± 2.080 and 3.8 ± 1.730 respectively. Conclusion: This study concluded that there is effect of physical therapy on electromyography and nerve conduction velocity on early prognosis of Bell’s palsy.
