Randomised controlled trial of yoga and bio-feedback in management of hypertension

Lancet. 1975 Jul 19;2(7925):93-5. doi: 10.1016/s0140-6736(75)90002-1.


34 hypertensive patients were assigned at random either to six weeks' treatment by yoga relaxation methods with bio-feedback 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).
