Exhibition of Postural Time-Force Parameters in Varying Severity of Osteoarthritis of Knee During Performing Sit-To-Stand Testing

Abstract

Background: Knee osteoarthritis (OA) is an irreversible leading cause of disability in elder. Clinical and research assessment for knee osteoarthritis often use radiographic finding to determine the disease severity. But recently research found that radiographic diagnosis couldn’t reflect the functional activity of life capacity of patient with knee osteoarthritis. Load distribution influence functional capacity of patient with knee osteoarthritis. It is important to know the correlation between performance and functional capacity of knee osteoarthritis patients. Purpose: In this study, a sit-to-stand task was chosen to compare the force-plate measured time-force parameters and weight bearing asymmetry degree in knee osteoarthritis patients with different functional severity.
