Effect of demographic factors, anthropometric factors, and comorbid diseases on recovery in the Bell's palsy subjects – A correlation study

OBJECTIVES: Bell's palsy is a condition of unilateral facial paralysis with the recovery rate varying from person to person. Various factors influence the prognosis of Bell's palsy subjects. Hence, the aim of this research was to examine the relationship between recovery of Bell's palsy and demographic, anthropometric, and the presence of comorbid diseases. METHODOlOGY: A correlation study was conducted on a total of 70 (both male and female) subjects. Independent outcome measures were age, gender, side, height, weight, body mass index, presence of diabetes, hypertension, and dyslipidemia. Dependent outcome measure was Sunnybrook Facial Grading System which grades the recovery following Bell's palsy. Outcome measures were taken at baseline, after 20 days, and after 1 month. RESULTS: Statistical analysis indicates that age, weight, diabetes, hypertension, and dyslipidemia have a significant correlation with recovery in Bell's palsy patients. CONCLUSION: The positive correlation between weight and recovery indicated that low weight leads to delayed recovery. A negative correlation of recovery with age, diabetes, hypertension, and dyslipidemia indicates that increased age leads to delayed or incomplete recovery and the presence of comorbid diseases leads to delayed/incomplete recovery.
