BACKGROUND: @entity1 with @entity571 ( @entity571 ) of the knee experience @entity158 and deconditioning that lead to disability. This study challenged the clinical belief that repetitive lower extremity exercise is not indicated in @entity1 with knee @entity571 . The effects of high-intensity and low-intensity stationary cycling on functional status, gait, overall and acute @entity158 , and aerobic capacity were examined. METHODS: Thirty-nine adults (71+/-6.9 years old) with complaints of knee @entity158 and diagnosis of @entity571 were randomized to either a high-intensity (70% heart rate reserve [HRR]) or low-intensity (40% HRR) exercise group for 10 weeks of stationary cycling. @entity1 cycled for 25 minutes, 3 times per week. Before and after the exercise intervention they completed the Arthritis Impact Measurement Scale 2 for @entity158 assessment, underwent timed chair rise, 6-minute walk test, gait, and graded exercise treadmill tests. Acute @entity158 was reported daily with a visual analog scale and the Western Ontario and @entity571 Index scale. RESULTS: Analysis of variance revealed that @entity1 in both groups significantly improved in the timed chair rise, in the 6-minute walk test, in the range of walking speeds, in the amount of @entity158 relief, and in aerobic capacity. No differences between groups were found. @entity158 reports suggested that cycling did not increase acute @entity158 in either group. CONCLUSIONS: Cycling may be considered as an alternative exercise modality for @entity1 with knee @entity571 . Low-intensity cycling was as effective as high-intensity cycling in improving function and gait, decreasing @entity158 , and increasing aerobic capacity.
