Researchers from Boston University have found that walking reduces the risk of functional limitation associated with knee osteoarthritis (OA). The study, in part funded by the NIH (National Institutes of Health), was just published in Arthritis Care & Research. The researchers measured the daily steps taken by nearly 2,000 people with—or at risk for—knee OA. All participants were part of the Multicenter Osteoarthritis Study; each person had his or her walking measured for seven days and their functional limitation evaluated two years later.
Bottom line: Dr. Daniel White said, ” … despite the common popular goal of walking 10,000 steps per day, our study finds only 6,000 steps are necessary to realize benefits. We encourage those with or at risk of knee OA to walk at least 3,000 or more steps each day, and ultimately progress to 6,000 steps daily to minimize the risk of developing difficulty with mobility.”
