The purpose of this study was to determine the odds ratio of increasing functional ability following 16 weeks of isometric or dynamic strength training among adults with knee OA. At baseline and following 16 weeks on interventions (posttest), subjects completed assessments of their perceived knee pain, stiffness and functioning, leg strength, gait characteristics, and functional ability. Functional ability was assessed as the duration to complete four functional tasks. These tasks included descending and ascending a flight of stairs and transferring from a standing to a supine position and from a supine to a standing position. The 35 and 32 subjects who were randomized to the dynamic and isometric strength training groups respectively performed six different dynamic strength training exercises involving the hip, knee and ankle, using TheraBand®, three times per week for 16 weeks. The 35 subjects randomized to the control group were given no intervention. Change scores (posttest minus baseline) were calculated for all of the measures and then dichotomized into improvement or no improvement categories. Functional ability was dichotomized as improving or failing to improve on all four functional tasks. Odds ratios (OR) were calculated to determine which change scores determined a significant odds ratio of being classified into one of the two functional ability categories. Subjects in both the intervention groups had significantly increased odds of improvement in functional ability relative to the control group. Being male, improvements in leg strength, perceived pain, perceived stiffness, perceived function, and gait velocity were also significantly associated with improvement in functional ability. After adjusting for these predictors, both the isometric and dynamic exercise groups were associated with improved functional ability with OR equaling 12.55 and 8.01 respectively. These findings indicate that participation in a strength-training program increases the odds of improved functioning among adults with OA of the knee. AN: MN030271
