Physical therapy may be doing more harm than good for hip osteoarthritis patients after a new study published in JAMA found that it was no better than placebo treatment in improving pain or function but was instead linked with relatively frequent but mild adverse effects.
Hip osteoarthritis is a prevalent and costly chronic musculoskeletal condition. Clinical guidelines recommend physical therapy as treatment, however costs are significant, and evidence about its effectiveness is inconclusive, according to background information in the article.
Kim L. Bennell, Ph.D., of the University of Melbourne, Australia, and colleagues randomly assigned patients with hip osteoarthritis to attend 10 sessions of either active treatment (n = 49; included education and advice, manual therapy, home exercise, and walking aid if appropriate) or sham treatment (n = 53; included inactive ultrasound and inert gel). For 24 weeks after treatment, the active group continued unsupervised home exercise while the sham group self-applied gel three times weekly.
"These results question the benefits of such a physical therapy program for this patient population," the authors conclude.
