Objective
The objective of this study is to compare the effects of PNF (proprioceptive neuromuscular facilitation) versus conventional exercises in subjects with Bell’s palsy for improving facial symmetry and facial motor function.
Background of the Study
Bell’s palsy is a lower motor lesion of facial nerve that causes unilateral paralysis of facial muscles. Bell’s palsy can recover with or without treatment. Most people notice an improvement in 2 to 3 weeks but a complete recovery can take up to 9 months. Physiotherapy treatment is found to fasten the recovery. Hence this study was intended to compare the effects of PNF and conventional exercises in accelerating the recovery of facial function and facial symmetry.
Methods
A group of 20 subjects who met the inclusion criteria were randomized into two groups. Group A received PNF along with electrical stimulation and group B received conventional exercises along with electrical stimulation for 6 weeks. Sunny brook facial grading and facial disability index were administered to find the progression in facial symmetry and facial function respectively.
Results
Statistically the calculated ‘t’ value for Sunnybrook facial grading system as well as functional disability index was significantly higher in group A, who received PNF along with electrical stimulation which means PNF added along with electrical stimulation has a greater effect on the recovery of Bell’s palsy.
