Background: Due to limited literature, on the usage of Sunnybrook Facial Grading scale (SFGS), we attempt to address SFGS in measuring clinical outcomes and understand its correlation with NVCs to predict the recovery course.

Objectives: 1. To correlate the findings of Nerve Conduction Velocity studies on SFGS in subjects with Bell’s palsy. 2. Also based on the correlation to find whether Nerve Conduction Velocity studies can be used as a prognostic indicator/tool in Bell’s palsy.

Methodology: A total of 58 subjects with unilateral Bell’s palsy were selected for the study. Outcome measures, SFGS and NCVs were evaluated on the first day and 20th day.

Results: Karl Pearson’s correlation coefficient showed a strong positive correlation between the amplitude of frontalis and mentalis muscle.

Conclusion: A positive correlation of the amplitude of frontalis and mentalis muscle.

Keywords: Nerve Conduction velocity studies, Sunnybrook Facial Grading scale, Bell’s palsy, correlation and prognostic tool.
