Another tool in the OA toolbox
Nick Trasolini, MD, of Wake Forest University School of Medicine, Winston-Salem, N.C., described the benefits in the trial as “modest” and noted that the improvement in function did not meet the threshold for minimal clinically important difference.
“Nevertheless,” he said in a written comment, “the [yoga] program was safe and associated with high participant satisfaction [mean satisfaction, 8 out of 10]. While this may not be the ‘silver bullet,’ it is another tool that we can offer to sufficiently motivated patients seeking non-operative solutions for knee osteoarthritis.”
Unfortunately, these tools remain “fraught with challenges,” Dr. Trasolini added.
“While multiple injection options are available (including corticosteroid, hyaluronic acid viscosupplementation, and biologic injections), the benefits of these injections can be short-lived,” he said. “This is frustrating to patients and physicians alike. Physical therapy is beneficial for knee osteoarthritis when deconditioning has led to decreased knee, hip, and core stability. However, physical therapy can be time consuming, painful, and cost prohibitive.”
In the present study, participants in the yoga group were somewhat willing (mean willingness, 5 out of 10) to pay for their 12-week yoga program. They reported that they would pay approximately $80 U.S. dollars for chance to do it all again.
The study was supported by grants from the National Health and Medical Research Council Program and the Centres of Research Excellence. The investigators disclosed additional relationships with Pfizer, Lilly, TLCBio, and others. Dr. Trasolini disclosed no relevant conflicts of interest.
