MON Sept., Feb. 19, 2022 (HealthDay News) — An unsupervised online yoga program and online training slightly improved physical function, but not knee pain during walking, at 12 weeks compared to training alone online in people with knee osteoarthritis, according to a study published online in September. 20 in the Annals of Internal Medicine.
Kim L. Bennell, Ph.D., of the University of Melbourne in Australia, and colleagues examined the effectiveness of a 12-week unsupervised online yoga program in a randomized clinical trial involving 212 adults with diabetes. symptomatic osteoarthritis of the knee. Both groups received online information about osteoarthritis, and the yoga group also had access to an unsupervised yoga program delivered via pre-recorded videos. Changes in knee pain during walking and physical function at 12 weeks and 24 weeks were the primary outcomes.
Overall, 195 and 189 participants (92 and 89%, respectively) provided primary outcomes at 12 and 24 weeks, respectively. Researchers found that yoga improved function compared to control at 12 weeks (mean difference in change between groups, -4.0), but no change was seen in knee pain while walking. For both outcomes, more yoga participants than control participants achieved the minimum clinically important difference. Knee stiffness, quality of life, and arthritis self-efficacy improved more with yoga than with the 12-week control. At 24 weeks, the benefits were not maintained. Minor adverse events were observed.
“A 12-week unsupervised online yoga program for people with knee osteoarthritis improved function more than online education immediately after the program, although the improvement did not reach the minimal difference clinically important and was not maintained at 24 weeks,” the authors write.
