Summary
This study tests whether doing leg exercises with a blood pressure cuff on the thigh can temporarily reduce pain in people with severe knee osteoarthritis who are waiting for knee replacement surgery. Forty-five participants will do two different exercise sessions (with either fixed or changing cuff pressure) to see which works better for pain relief. The goal is to find a simple, drug-free way to help manage pain before surgery.
