Treatment and management of hypertension, as well as drug therapy, are widely used for a healthy diet, exercise, non-smoking, and non-pharmacic treatments.
 Recently, interest in Qi gong and Tai Chi has increased as a way to treat hypertension in traditional Korean medicine clinic. 
 This study aims to verify the efficancy of the Tai Chi by comparing the randomized and usual care group of high blood pressure patients with primary hypertension (ages 19 to 70).
 The Tai Chi group, which operates the Tai Chi twice a week (80 percent compliance and more than 13 times in total), will receive 8 weeks of exercise, and the usual care group will receive training at the hospital about salt intake restriction, weight loss, alcohol consumption, exercise, and meal control, and they are administered by themselves for 8 weeks. Since then, both will be monitored in four weeks.
 The primary outcome is the difference between the systolic and the relaxation period blood pressure, and the secondary outcome include comparing the body components before and after, changes in heart rate per minute, and evaluation of motor strength and difficulty of exercise for the Tai Chi.

Treatment

The Tai Chi group, which operates the Tai Chi three twice a week (80 percent compliance and more than 13 times in total), will receive 8 weeks of exercise, and the usual care group will receive training at the hospital about salt intake restriction, weight loss, alcohol consumption, exercise, and meal control, and they are administered by themselves for 8 weeks. Since then, both will be monitored in four weeks. Since the intervention of the control group and the experimental group of the study is not possible to perform participant blind, this study does not perform participant blind but only assessor blind.

Description

1) Stage 1 hypertensive patients who were diagnosed at the health checkup and hospital or were screened for systolic blood pressure of 140 to 159 mmHg or diastolic blood pressure of 90 to 99 mmHg
2) A person who can communicate normally
3) Participants who signed a study agreement with a voluntary participation intention

2) A person who is deemed difficult to treat exercise for high blood pressure through the judgment of a doctor, such as a severe pain condition or joint deformation
3) A person who is unable to communicate properly due to dementia or mild cognitive impairment
4) A person who is pregnant

41 participants were recruited out of a total of 80. There was no difference between the experimental group and the control group in the difference of systolic blood pressure before and after treatment, and in the change of diastolic blood pressure before and after treatment. The difference in heart rate per minute and body composition, which were secondary outcomes, also showed no difference between the experimental group and the control group. Intensity and difficulty of the exercises, which were other secondary outcome, did not have a significant correlation with changes in blood pressure. No adverse events were reported.
