Efficacy of Hip Strengthening on Dynamic Knee Stability, Disability and Gait in Knee Osteoarthritis

Efficacy of Hip Strengthening on Dynamic Knee Stability, Disability and Gait in Knee Osteoarthritis

this study will be conducted to investigate the role of hip strengthening in improving dynamic knee stability, gait parameter, lower extremity strength and disability in knee osteoarthritis

knee osteoarthritis accounts for more than 80% of the total burden of the diseases. patients with knee osteoarthritis had worse spatiotemporal gait parameter and dynamic instabitity. there are significant hip muscle weakness in knee osteoarthritis. hip muscle weakness leads to improper alignment and stress in knee joint. hip muscle strength can affect knee joint loading and disease progression in knee osteoarthritis. muscles of the lower extremity play a critical role in the preservation of normal knee joint function by providing dynamic knee joint stability and shock absorption, while maintaining safe transfer of forces across the joint.
