...Ralph Schumacher, of the University of Pennsylvania School of Medicine, and Marian Garfinkel, a yoga teacher, published a brief paper on carpal tunnel syndrome in the Journal of the American Medical Association. The eight-week study determined that "a yoga-based regimen was more effective than wrist splinting or no treatment in relieving some symptoms and signs of carpal tunnel syndrome." Letters to JAMA challenged the study's methodology. The authors replied that it was a preliminary investigation to determine if further research was merited. They said...
...most cited study around - Ornish's in 1990 - tested 94 patients with angiographically documented coronary heart disease, of whom 53 were prescribed yoga, group support and a vegetarian diet extremely low in fat - only 10% of total daily calories (most Americans consume 35% in fat; the American Heart Association recommends 30%). Cholesterol changes among the experimental group were about the same as if they had taken cholesterol-lowering drugs. After a year in the program, patients in this group showed "significant overall regression of coronary atherosclerosis as measured by quantitative coronary arteriography." Those in the control group "showed significant overall...
...Ornish published a new study, in the American Journal of Cardiology, stating that 80% of the 194 patients in the experimental group were able to avoid bypass or angioplasty by adhering to lifestyle changes, including yoga. He also argued that lifestyle interventions would save money - that the average cost per patient in the experimental group was about $18,000, whereas the cost per patient in the control group was more than $47,000. And this time, Ornish says, he is convinced that "adherence to the yoga and meditation program was as strongly correlated with the changes in the amount...
...Ornish hoped for more than the respect of his peers: he wanted action. "I used to think good science was enough to change medical practice," he says, "but I was naive. Most doctors still aren't prescribing yoga and meditation. We've shown that heart disease can be reversed. Yet doctors are still performing surgery; insurance companies are paying for medication - and they're not paying for diet and lifestyle-change education." (Medicare, however, recently agreed to pay for 1,800 patients taking Ornish's program for reversing heart disease...
...have so few studies tested the efficacy of yoga? For lots of reasons. Those sympathetic to yoga think the benefits are proved by millenniums of empirical evidence in India; those who are suspicious think it can't be proved. (Says Coble: "There seem to be no data to substantiate the argument that yoga can heal.") Further, its effects on the body and mind are so complex and pervasive that it would be nearly impossible to certify any specific changes in the body to yoga. The double-blind test, beloved of traditional researchers, is impossible when one group in a study...
