Therapeutic Exercise Reduces Pain and Improves Function for Patients With Knee Osteoarthritis
The Cochrane Library collected several studies about exercise benefits for osteoarthritis. The review found that exercise can help decrease pain and increase functionality in people with OA. A second review, published in the Arthritis and Rheumatism Journal , gathered information specifically about strength training, and found similar results.
About the Study
The second review focused on strength training for OA. Researchers at the University of Sydney reviewed 18 randomized trials that evaluated the effect of strength training on pain and function in participants with knee osteoarthritis. The review had a total of 2,832 participants. Results were self-reported or measured. In general:
- 50%-75% of the studies reported improved pain and physical function in strength training groups
- 50%-100% of the studies had a significant improvement in the performance-based physical function measure (walk time)
How Does This Affect You?
Both of these studies only reviewed short-term benefits of exercise for OA. They also did not focus on specific time and amounts of exercise. However, the results are promising in providing benefits for people with knee osteoarthritis.
