A new study finds that one hour of brisk walking weekly reduces the risk of mobility-related disability by 85% in senior people with osteoarthritis.
A team of researchers from the Northwestern University of Feinberg School Medicine in Chicago, US, analyzed data from over 1,500 adults whose medical information had been collected as a part of the US national Osteoarthritis Initiative.
The lead of the study professor Dorothy Dunlop explains: “We hope this new public health finding will motivate an intermediate physical activity goal. One hour a week is a stepping stone for people who are currently inactive. People can start to work toward that.”
To examine the benefits of a low-carb diet, the researchers included 21 adults aged from 65 to 75 with the condition into the study. The participants stick either of the two diets or continued their ordinary diet for 12 weeks.
Having analyzed the received data, the scientists found that the diet with low content of carbohydrates reduced functional pain levels and levels of self-reported pain.
Study leader Robert Sorge from the PAIN Collective in the University of Alabama at Birmingham Department of Psychology, says: “Diet will never ‘cure’ pain, but our work suggests it can reduce it to the point where it does not interfere with daily activities to a high degree.”
A new research from Switzerland suggests that a substance extracted from brown algae could potentially treat osteoarthritis. The research was led by Professor Marcy Zenobi-Wong from the Eidgenössische Technische Hochschule (ETH), and Dr. Katharina Maniura, from Empa.
With the help of the experiments in vitro, the scientists discovered that polysaccharide alginate derivatives extracted from the stems of brown algae Laminaria hyperborean can strop joint cartilage deterioration.
The researchers believe that development of a clinical solution target the condition itself, not its symptoms, would greatly improve the quality of life, as well as allow people with the disease to avoid complications that one day could lead to disability and surgery of joint replacement.
A recent research discovered that nowadays knee arthritis is more than twice as common as it used to be only a few generations ago. Scientists say that the risk of developing the condition is 46% now.
Dr. Jordan Metzl, a sports medicine physician at New York’s Hospital for Special Surgery, says that this phenomenon could be influenced by inactivity of modern life. The study demonstrates that cases of developing arthritis more than doubled these days.
Dr. Metzl explains: “The best thing to do is strengthen your muscles with exercises like squats and lunges instead of saying off of the knee and, in effect, becoming more inactive.
A new research, which was a collaborative effort of researchers from Tufts University in Boston, USA, and the University of Manchester, UK, demonstrates that diet rich in fiber may cut the risk of developing osteoarthritis.
For the study, the researchers completed a meta-analysis of two long-term studies on the benefits of diets rich in fiber. The scientists found that the participants who consumed the most fiber had a 30% lower risk of osteoarthritis in OAI cohort, and 61% lower risk of OA in the Framingham cohort, compared with people who ate the least fiber.
Dr. Zhaoli Dai, a lead researcher of the study of the Human Nutrition Research Center on Aging and Friedman School of Nutrition Science and Policy at Tufts University, says: “Findings from two longitudinal studies consistently showed that higher total fiber intake was related to a lower risk of [symptomatic], while the relation to [incident radiographic OA] was unclear.”
