Abstract: The purpose of this reseach was to explore the relation between bio-feedback and hypertension in clinically objective indices.39 hypertensiveswere randomly assigned into 3 groups; 1) the biofeedback group, 2) themuscle relaxation group, 3)the biofeedback-assisted with muscle relaxa-tion group. After one month's training, the systolic and diastolic bloodpressure (BP) in the biofeedback group decreased very significantly; butthe muscle relaxation group showed significant decrease only in systolicpressure. The effect of the therapy in the biofeedback assisted withmuscle relaxation group was similar to that of the biofeedback group. Theresults suggest that the biofeedback could play an important role inhypertension therapy but the function of muscle relaxation was limited.
