Qigong Effective in Reducing Blood Pressure in Hypertension Patients
October 15, 2014 -
High blood pressure treatments include
sodium restriction, pharmacological management, and lifestyle modifications.
Although many cases of high blood pressure can be controlled by medication,
individuals may experience side effects or incur out-of-pocket expenses, and
some may not comply with the treatment regimen. Although some previous studies
have shown a favorable effect for Qigong on
high blood pressure, well-designed, rigorous trials evaluating the effect of Qigong on high blood pressure are scarce.
A study recently reported by the journal Alternative therapies in health and
medicine aimed to evaluate the effect of Qigong on
prehypertension and mild high blood pressure and to calculate a sample size for
a subsequent randomized, clinical trial (RCT).
This study was conducted at the Oriental
Medical Center of Dongeui University, in the Republic of Korea. Participants
were randomized to a Qigong group
or an untreated control group.
Participants were individuals between the
ages of 19 and 65 years with systolic blood pressure (SBP) between 120 and 159
mm Hg and/or diastolic blood pressure (DBP) between 80 and 99 mm Hg.
The Qigong group
attended Qigong classes 3 times a week and performed Qigong at home at least 2 times a week.
Participants in the control group did not receive any intervention for high
Outcome measures for this study were (1)
changes in blood pressure (BP); (2) quality of life (QOL) using 2 surveys: the
Medical Outcomes Study (MOS) 36-item short form (SF-36) (Korean version) and the
Measure Yourself Medical Outcome Profile 2 (MYMOP2); and (3) hormone levels.
Of 40 participants, 19 were randomly assigned to the Qigong group,
and 21 were assigned to the control group. After 8 weeks, significant
differences were observed between the Qigong and
the control groups regarding changes in SBP. Among the categories of the MYMOP2
questionnaire, only wellbeing was significantly different between the 2 groups.
The Qigong group showed a significantly greater
improvement in the physical component score of the SF-36 compared with the
control group. Regarding changes in hormone levels, there was no significant
difference between the Qigong aand
the control groups.
The results indicate that Qigong/span> may
be an effective intervention in reducing blood pressure in prehypertension and
mild high blood pressure patients. Further studies should include an appropriate
sample size and methodology to determine the mechanism of
