"Objective To determine which lower limb strength and joint kinetic and kinematic parameters distinguish sit-to-stand (STS) performance of older adults with symptomatic knee osteoarthritis (OA) with higher and lower chair stand time. Design Cross-sectional. Setting Motion analysis laboratory. Participants Individuals (N=49; 26 men, 23 women) aged 50 to 79 years (mean + SD age, 64.7+8.1y) with radiographic knee OA and daily symptoms, stratified by chair stand times. Interventions Not applicable. Main Outcome Measures Lower limb strength and STS strategy. Results The chair stand times (mean + SD) in the high-, moderate-, and low-functioning groups in men were 6.5+0.7, 8.6+0.7, and 11.5+1.3 seconds, respectively, and in women were 7.6+1.2, 10.0+0.5, and 12.8+1.8 seconds, respectively. Chair stand time (P=.0391) and all measures of lower limb strength (all P<.0001 differed by sex. in men no strength measure between groups whereas women hip abductor on the more affected side groups. sagittal range of motion and there was a trend toward difference knee power during sts while only rom> Conclusions Higher- and lower-functioning adults with symptomatic knee OA appear to use different strategies when standing from a chair. Higher-functioning men flexed more at the hip and produced greater knee power than lower-functioning men. Higher-functioning women used less knee flexion than lower-functioning women. Since STS is an important mobility task, these parameters may serve as foci for rehabilitation aimed at reducing mobility limitations." |
