Randomized Controlled Trial of Yoga and Biofeedback in Management of Hypertension
Thirty-four hypertensive patients were assigned at random either to 6 weeks’ treatment by yoga relaxation methods with biofeedback or to placebo therapy (general relaxation). Both groups showed a reduction in blood pressure (from 168/100 to 141/84 mm Hg in the treated group and from 169/101 to 160/96 mm Hg in the control group). The difference was highly significant. The control group was then trained in yoga relaxation, and their blood pressure fell to that of the other group (now used as controls).
