Yoga has significant benefits for those with arthritis. As documented at Yoga4arthritis.com, clinical studies have shown, among other things “Significant differences between [control and yoga-practicing] groups were found for: balance, flexibility, depressive symptoms, positive and negative affect. There was also improvement in the number of tender and swollen joints for patients with RA.” Steffany Moonaz played a key role in those studies, and now provides classes and other resources for yoga teachers to teach to arthritis sufferers. A countervailing perspective is that of Cramer et al who assert ” Based on the results of this review, only weak recommendations can be made for the ancillary use of yoga in the management of FM [fibromyalgia] syndrome, OA [osteoarthritis] and RA [rheumatoid arthritis] at this point”.
Also, Carson et al (2012) found that yoga is helpful for fibromyalgia.
