6,000 steps a day keeps knee OA limitations away

12.06.2014

A new study shows that walking reduces risk of functional limitation associated with knee osteoarthritis (OA). In fact, the study funded in part by grants from the National Institutes of Health (NIH) and published in the American College of Rheumatology (ACR) journal, Arthritis Care & Research, suggests that walking 6,000 or more steps per day may protect those with or at risk of knee of OA from developing mobility issues, such as difficulty getting up from a chair and climbing stairs.

Nearly 27 million Americans age 25 and older are diagnosed with OA according to a prevalence study by Lawrence et al. (Arthritis Rheum, 2008). Previous research reports that knee OA is the leading cause of functional limitation among older adults, making walking and climbing stairs difficult.

Moreover, data from the National Health and Nutrition Examination Survey (NHANES III) state that 80% of OA patients have some limitation in movement, with 11% of adults with knee OA needing assistance with personal care assistance.

While walking is a common daily physical activity for older adults, medical evidence reports that two-thirds of U.S. adults with arthritis walk less than 90 minutes each week.

"Our study examines if more walking equates with better functioning, and if so, how much daily walking is needed to minimize risk of developing problems with mobility in people with knee OA," said Daniel White, PT, ScD, from Sargent College at Boston University in Massachusetts.

For the present study, researchers measured daily steps taken by 1788 people with or at risk for knee OA, who were part of the Multicenter Osteoarthritis Study. Walking was measured with a monitor over seven days and functional limitation evaluated two years later, defined as a slow walking speed and a Western Ontario and McMaster Universities Arthritis Index (WOMAC) physical function score greater than 28 out of 68.

Walking an additional 1,000 steps each was associated with between a 16% to 18% reduction in incident functional limitation two years later. Walking less than 6,000 steps daily was the best threshold for identifying those who developed functional limitation. Dr. White concludes, "Walking is an inexpensive activity and 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."

About the Journal

Arthritis Care & Research is an official journal of the American College of Rheumatology (ACR), and the Association of Rheumatology Health Professionals (ARHP), a division of the College. Arthritis Care & Research is a peer-reviewed journal that publishes both original research and review articles that promote excellence in the clinical practice of rheumatology. Relevant to the care of individuals with arthritis and related disorders, major topics are evidence-based practice studies, clinical problems, practice guidelines, health care economics, health care policy, educational, social, and public health issues, and future trends in rheumatology practice. The journal is published by Wiley on behalf of the ACR. For more information, please visit the journal home page at http://wileyonlinelibrary.com/journal/acr.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
