Towards healthier knees — ScienceDaily
A new study published today in Arthritis and rheumatology by researchers at Baylor College of Medicine finds that walking for exercise can reduce new knee pain common in people 50 and older who have been diagnosed with knee osteoarthritis, the form of arthritis the most common. Additionally, the study results indicate that walking for exercise may be an effective treatment for slowing the damage that occurs in the joint.
“Until this discovery, there was a lack of credible treatments that provide benefits for both damage and pain limitation in osteoarthritis,” said Dr. Grace Hsiao-Wei Lo, assistant professor of immunology. , Allergy and Rheumatology at Baylor, Chief of Rheumatology at the Michael E. DeBakey VA Medical Center and first author of the article.
The researchers looked at results from the Osteoarthritis Initiative, a multi-year observational study where participants self-reported how long and how often they walked for exercise. Participants who reported 10 or more exercises from age 50 or older were categorized as ‘walkers’ and those who reported fewer were categorized as ‘non-walkers’.
Those who reported walking for exercise had a 40% lower risk of frequent new knee pain compared to non-walkers.
“These results are especially helpful for people who have radiographic signs of osteoarthritis but don’t have daily knee pain,” said Lo, who is also a researcher at the Center for Innovations in Quality, Effectiveness, and Safety at Baylor and the VA. “This study supports the possibility that walking for exercise may help prevent the onset of daily knee pain. It may also slow the worsening of damage inside the joint caused by osteoarthritis. .”
Lo said walking for exercise has added health benefits such as better cardiovascular health and a lower risk of obesity, diabetes and certain cancers, the driving reasons behind the Center for Disease Control on physical activity, first published in 2008 and updated in 2018. because exercise is a free activity with minimal side effects, unlike drugs, which often have a substantial price and the possibility of ‘Side effects.
“People with knee osteoarthritis should walk for exercise, especially if they don’t have daily knee pain,” advises Lo. “If you already have daily knee pain, there could still be a benefit, especially if you have the type of arthritis where your knees are bowlegged.”
