Acute polio is no longer a constant threat to people in the polio–free areas of the world,but there are still thousands of polio survivors who are at risk of developing late manifestations of the disease, known as post–polio syndrome (PPS) which presents with new or increased muscle weakness and muscle fatigability as key symptoms.This study aims to determine the functional capacity in subjects with PPS and its correlation with pain and physical function.Functional capacity strongly correlates with pain(rho=–0.60, p=0.01) and weakly correlates with physical function(rho=0.33,p=0.003).Pain is a predictor of functional capacity, and accounted for 33.7% variance, highlighting the need of appropriate intervention strategies to improve the functional capacity in individuals with PPS.
