Analysis of Activity Patterns and Performance in Polio Survivors

摘要

The goals of this project were: (1) to study the temporal relationship between activity level and health status in polio survivors and to compare the results with those obtained from an age-matched control population and (2) to look at the effect of localized muscle weakness and the associated compensation response on performance of a walking task. Simulation modeling techniques were used to identify factors critical to task performance, which provided valuable information for optimizing rehabilitation interventions for polio survivors and other populations with lower extremity muscle weakness. A total of 97 polio survivors and 116 controls were enrolled and tested for Study No. 1. Longitudinal data was analyzed. For Study No. 2, the functional deficits database was compiled and an analysis was performed using the mechanical-based compensation scheme.
