Effects of a Yoga Intervention on Adults with Lower Limb Osteoarthritis: a Randomized Controlled Trial

This study investigated the effectiveness of a yoga exercise and relapse prevention program on physical health outcomes, predictors of exercise and exercise adherence in adults aged 40-64 years with osteoarthritis. A yoga intervention was first implemented to all the participants, and then participants were randomized into one of two conditions: a relapse prevention program, which provided continued encouragement and guidance for practicing yoga, and a control group. Results (two-way repeated measures ANOVA) indicated that participation in the yoga intervention significantly improved pain (P<0.001), physical function (P<0.001) and physical activity levels (P=0.003), but the relapse prevention interven-tion provided no added benefit.
