Abstract: Hypertension is a major risk factor for cardiovascular morbidity and mortality. It is paramount that the resting blood pressure is within normal limits for safe prescription of exercise. Burst TENS on peripheral vascular resistance implies a sympathetic inhibition which results in peripheral vasodilatation which results in lower blood pressure. Sixty patients of either gender of 30-65 years diagnosed as essential hypertension were recruited for the study. The patients in experimental group received Burst TENS and in control group received Sham TENS for 30 minutes. Pre - post blood pressure measurements were noted inboth the groups and compared for statistical significance. The exercise blood pressure response to six minute walk test was studied with and without
