Many people assume that knee OA predominantly affects the elderly; however, 56% of Canadians with OA are younger than 65. Another common misconception is that exercise will damage joints. Studies have shown that range of motion exercises, combined with stretching, aerobics, and strength training, can help modulate pain, increase range of motion, and reduce soft tissue inflammation. Losing weight can also make a difference. For every 1 lb of weight lost, there is 4 lb less of force through the knee in every step you take. If you were to lose 10 lb, that would reduce 48,000 lb of load through the knee for every mile walked! Kristi Hunter, MPT, BSc, Certified in Acupuncture, Prairie Trail Physio, PrairieTrailPhysio.ca
