Effects of Progressive Muscle Relaxation on Blood Pressure and Psychosocial Status for Clients with Essential Hypertension in Taiwan

Abstract

This study examined the effect of progressive muscle relaxation (PMR) on blood pressure and psychosocial status in clients with essential hypertension. The study, which used a quasi-experimental design, recruited a convenience sample of 40 subjects from a hypertension outpatient clinic. Twenty subjects received PMR training once a week and practiced at home daily for 4 weeks. PMR training had an immediate effect, reducing pulse rate 2.35 beats/min, systolic blood pressure 5.44 mm Hg, and diastolic blood pressure 3.48 mm Hg. After 4 weeks of PMR training, further decreases in pulse rate (2.9 beats/min), systolic blood presurre (5.1 mm Hg), and diastolic blood pressure (3.1 mm Hg) occurred. PMR significantly lowered patients' perception of stress, and it enhanced their perception of health. PMR is beneficial for patients with essential hypertension, and nurses may use it to enhance their independent function as well as their quality of life.
