Osteoarthritis (OA) is a degenerative joint disease that primarily affects the knees and becomes more prevalent with age. In individuals over 50, particularly those with bilateral knee osteoarthritis, it leads to chronic pain, limited mobility, and functional decline. This condition worsens due to muscle strength imbalances, especially in the quadriceps and hamstrings. These imbalances are triggered by pain, joint instability, and cartilage damage, which negatively impact muscle strength and coordination. In women, these asymmetries are more pronounced, increasing the risk of functional decline. Recent studies highlight the significant role of strength asymmetry in functional limitations, affecting balance, gait, and daily activities. This study aims to investigate the impact of bilateral quadriceps and hamstring strength asymmetries on dynamic balance, gait efficiency, and functional mobility in older women with bilateral knee osteoarthritis. The study aims to examine the effects of bilateral strength asymmetries in the knee extensors and flexors on dynamic balance, gait efficiency, and overall mobility in older women with bilateral knee osteoarthritis. We hypothesize that greater strength asymmetry will be associated with impaired dynamic balance, reduced gait efficiency, and decreased functional mobility.
