Study Overview
Brief Summary
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
Detailed Description
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.

Arms & Interventions
hip strengthening
resistance training for hip abductor, hip extensor, and hip external rotator will be performed.cuff weights will be used with 80% of 1 repetition maximum at 3 sets of 8 repetitions with 10-15 second rest between repetitions and 1-2 minute rest between sets.
Intervention: hip strengthening (Other)

Intervention: quadriceps strengthening, stretch hamstring,cuff muscles (Other)
quadriceps strengthening, stretch for hamstring,cuff muscles
quadriceps strengthening: multi-angle isometric exercise from sitting position will be performed. cuff weights will be used with 3 sets of 12 repetitions at 40% of 1 reprtition maximum.
self stretch for hamstring and cuff muscles from supine position. the procedure will be repeated 4 times.
