Physical exercise and reduction of pain in adults with lower limb osteoarthritis: a systematic review.

Summary: Osteoarthritis of the hip and knee is a common, painful condition where joints degenerate over time. While medication and surgery are standard treatments, physical exercise is highly recommended to manage pain without drugs. A recent review analyzed 33 studies to see which exercises work best, grouping them into land-based activities (like strength training and Tai Chi), water-based therapy, and mixed programs.

Surprisingly, despite how often doctors recommend exercise, there are very few high-quality clinical trials confirming the best approach. The review found that exercise programs vary wildly in how they are structured. However, the data suggests that Tai Chi may offer better pain relief than mixed exercise routines, though the "perfect" exercise prescription remains unclear.
