Researchers from Tufts University School of Medicine have determined that patients over 65 years of age with knee osteoarthritis (OA) who engage in regular Tai Chi exercise improve physical function and experience less pain. Tai Chi (Chuan) is a traditional style of Chinese martial arts that features slow, rhythmic movements to induce mental relaxation and enhance balance, strength, flexibility, and self-efficacy. Full findings of the study are published in the November issue of Arthritis Care & Research, a journal of the American College of Rheumatology. http://www.physorg.com/news176014700.html Medicine & Health Thu, 29 Oct 2009 06:30:01 EST news176014700 A new study by researchers at the University of Iowa Hospitals and Clinics found that thigh muscle strength does not predict the occurrence of knee osteoarthritis (OA) uncovered in x-rays, but does predict incidence of painful or stiff knee OA. Women with the strongest quadriceps muscles appeared to be protected against the development of knee OA symptoms. Details of this study appear in the September issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. http://www.physorg.com/news170584634.html Medicine & Health Thu, 27 Aug 2009 10:00:01 EST news170584634 A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression. The biomarkers, described in BioMed Central's open access journal Arthritis Research and Therapy, will be useful for the design and interpretation of trials of new disease modifying drugs. http://www.physorg.com/news167632761.html Medicine & Health Fri, 24 Jul 2009 05:50:01 EST news167632761 Obesity, among other factors, is strongly associated with an increased risk of rapid cartilage loss, according to a study published in the August issue of Radiology. http://www.physorg.com/news166769500.html Medicine & Health Tue, 14 Jul 2009 05:53:58 EST news166769500 Total knee replacement (arthroplasty) appears to be a cost-effective procedure for older adults with advanced osteoarthritis, according to a report in the June 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The procedure appears to be cost-effective across all patient risk groups, and appeared more costly and less effective in low-volume centers than in high-volume centers. http://www.physorg.com/news164906963.html Medicine & Health Mon, 22 Jun 2009 18:30:02 EST news164906963 There is no good evidence supporting a harmful effect of exercise on joints in the setting of normal joints and regular exercise, according to a review of studies published in this month's issue of the Journal of Anatomy. http://www.physorg.com/news152279685.html Medicine & Health Tue, 27 Jan 2009 11:55:14 EST news152279685 Studies on the influence of quadriceps strength on knee osteoarthritis (OA), one of the leading causes of disability among the elderly, have shown conflicting results. In some studies, decreased quadriceps strength is associated with greater knee pain and impaired function, while other studies show mixed results on the effect of quadriceps strength on the structural progression of knee OA. http://www.physorg.com/news151089490.html Medicine & Health Tue, 13 Jan 2009 17:18:10 EST news151089490 A landmark government study suggests nearly one in two people (46%) will develop painful knee osteoarthritis over their lifetime, with the highest risk among those who are obese. According to the Arthritis Foundation, the study underscores the immediate need for the public to understand what they can do to reduce the tremendous pain, disability and cost associated with arthritis. http://www.physorg.com/news139657945.html Medicine & Health Wed, 03 Sep 2008 10:52:25 EST news139657945 Almost half of all U.S. adults and nearly two-thirds of obese adults will develop painful osteoarthritis of the knee by age 85, a study based at the University of North Carolina at Chapel Hill suggests. http://www.physorg.com/news139578926.html Medicine & Health Tue, 02 Sep 2008 12:55:26 EST news139578926
