Study Summary
Osteoarthritis (OA) in the knee is characterized by chronic inflammatory pain that is not necessarily related to the amount of joint damage. Clinical practice guidelines recommend physical activity (PA) for osteoarthritis pain, but most adults with OA do not engage in PA. One reason for this is that while PA can reduce OA related joint pain, it does not work for everyone. PA decreases pain sensitivity for about half of adults with OA but increases pain sensitivity for the other half. The investigators are hypothesizing that individual differences in how well cells work to make energy, inflammation, and different proteins available in blood cells explains who PA will work to reduce pain and who it won't among adults with OA. The purpose of this pilot study is to determine if blood cells' ability to make cellular energy, inflammation and proteins help explain the difference about who PA reduces activity for and who it doesn't. The investigators will compare these biologic factors and pain sensitivity before walking, immediately after 30 minutes of walking (i.e. "acute") and after six weeks of walking three times a week for 30 minutes (i.e. "long-term") in adults with hip or knee osteoarthritis. The investigators will also compare these results to adults without OA. The investigators will recruit a sample of 40 adults with radiologic (e.g x-ray or CT scan) evidence of hip or knee OA and 20 age/gender matched healthy adults without OA to address the following study aims: Aim 1: To examine the effects of a six week (three days/week) walking program on pain in adults with OA as compared to healthy controls. Aim 2: To test the cells' ability to make energy as a mechanism for variation in pain after "acute" and "long-term" PA in older adults with lower extremity osteoarthritis. Aim3: To test the role of inflammation as a mechanism for variation in pain after "acute" and "long-term" physical activity in adults with lower extremity osteoarthritis. Aim 4: To generate hypothese
Primary Outcome
