Exercise Eases Knee Arthritis
A therapeutic exercise program may reduce pain and improve movement for people with knee arthritis, at least for several months, according to a review of previous trials by a team of researchers in The Netherlands.
The review of previous research looked at 55 randomized controlled trials comparing a land-based exercise program with no exercise for people with osteoarthritis. The trials varied in type, duration and intensity of exercise programs.
The results showed that, in general, the exercise programs significantly reduced pain and moderately improved physical function of the knee immediately after treatment. Some studies also found that the general quality of life improved. Twelve of the studies followed up with participants two to six months later and found that knee pain was still at a lower level than it had been.
The researchers explained that if the knee is exercised and has more muscle strength, it will be more stable and less prone to wear and tear. They also noted that the most important factor is not which exercise is performed, but that the exercise is done regularly.
