Impact of Qigong Exercise on Self-Efficacy and Other Cognitive Perceptual Variables in Patients with Essential Hypertension

A pilot study on the impacts of lung-strengthening Qigong on wellbeing

BACKGROUND

Qigong embraces a range of self-care exercises originating from China. Lung-Strengthening Qigong (LSQ) is a specific technique for maintaining and improving physical and mental wellbeing.

METHODS

We recruited 170 practitioners and 42 non-practitioner/control samples to investigate the impacts of LSQ practice on body, mind, thoughts, and feelings. This is a pilot study pursued to plan for an adequately powered, non-clinical randomized controlled trials (RCT) on overall wellbeing and health and to evaluate the adequacy of delivering the physical activity intervention with fidelity. Self-evaluation-based data collection schemes were developed by regularly requesting completion of a questionnaire from both practitioner and control group, and an online diary and end of study survey (EOS) completion only from the practitioners. Diverse types of analyses were conducted, including statistical tests, machine learning, and qualitative thematic models.

RESULTS

We evaluated all different data resources together and observed that (a)the impacts are diverse, including improvements in physical (e.g., elevated sleep quality, physical energy, reduced fatigue), mental (e.g., increased positivity, reduced stress), and relational (e.g., enhanced connections to self and nature) wellbeing, which were not observed in control group; (b)measured by the level-of-effectiveness, four distinct clusters were identified, from no-effect to a high-level of effect; (c)a majority (84 %) of the LSQ practitioners experienced an improvement in wellbeing; (d)qualitative and quantitative analyses of the diary entries, questionnaires, and EOS were all found to be consistent, (e)majority of the positively impacted practitioners had no or some little prior experience with LSQ.

CONCLUSIONS

Novel features of this study include (i)an increased sample size vis-à-vis other related studies; (ii)provision of weekly live-streamed LSQ sessions; (iii)integration of quantitative and qualitative type of analyses. The pilot study indicated that the proportion of practitioners who continued to engage in completing the regular-interval questionnaires over time was higher for practitioners compared to the control group. The engagement of practitioners may have been sustained by participation in the regular live LSQ sessions. To fully understand the impacts of LSQ on clinical/physiological outcomes, especially for specific patient groups, more objective biomarkers (e.g. respiratory rate, heart rate variation) could be tracked in future studies.

Can Yoga, Qigong, and Tai Chi Breathing Work Support the Psycho-Immune Homeostasis during and after the COVID-19 Pandemic? A Narrative Review

Breathing is crucial in life; nevertheless, the healthcare community often overlooks the health potential of breathing techniques. Conscious manipulation of breathing to achieve specific health goals is found in yoga, Qigong and Tai Chi. This paper reviews the value of breathing exercises as a foremost mechanism for promoting, recuperating and maintaining health. Practices involving breathing techniques are described, and their prophylactic or therapeutic characteristics are explored. The main goals of this review are: (i) to summarize the evidence supporting the hypothesis that breathing practices have a significant beneficial impact on human health; (ii) to provide a deeper understanding of traditional biofeedback practices, particularly yoga, Qigong and Tai Chi, and outline their focus on breathing techniques; (iii) to outline specific immune-related responses, relevant for COVID-19 disorders; and (iv) to call for committed attention and action from the scientific community and health agencies in promoting the implementation of a practical and costless health program based on breathing techniques. This review shows the health potentials of breathing practices and exercises, which, by having a high benefit-cost ratio, could be selected and implemented as a primary standard routine in public health programs.

The Effect of Mind-Body Exercise on Blood Pressure in Middle-Aged and Elderly Patients with Hypertension: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objectives. The effects and safety of mind-body exercise in improving blood pressure in middle-aged and elderly patients with hypertension were explored in this meta-analysis. Methods. A meta-analysis of studies from the China National Knowledge Infrastructure, Web of Science, PubMed, and Cochrane was performed to identify related experimental studies by screening out the randomized controlled trials from the time of respective database creation until January 22, 2021. In addition, first, we completed the research registration on the INPLASY platform on March 20, 2021 (registration number: INPLASY202130072) and, second, on the PROSPERO platform on December 28, 2021 (registration number: CRD42021289125). The data were analyzed using a random-effects model with the help of Stata 14.0 software. Results. A total of 2,277 patients from 30 studies were reflected in the present study. The results show that mind-body exercise can effectively improve systolic blood pressure [SMD = −0.994, 95% CI: −1.239∼−0.748, $P<0.01$ ] and diastolic blood pressure [SMD = −0.757, 95% CI: −1.009∼−0.505, $P<0.01$ ] in middle-aged and elderly patients with hypertension. Conclusion. The results of this meta-analysis show that mind-body exercise can effectively improve blood pressure in middle-aged and elderly patients with hypertension without adverse events.

Inter-individual Response Differences on Resting Blood Pressure as a Result of Qigong in Adults: An Ancillary Meta-Analysis of Randomized Trials

OBJECTIVE

Conduct an ancillary meta-analysis to determine whether true IIRD exist with respect to the effects of qigong on resting SBP and DBP in adults.

METHODS

Data from a meta-analysis representing 370 participants (181 qigong, 189 control) from 7 randomized trials on qigong and resting SBP and DBP in men and women were included. Qigong and control group change outcome standard deviations treated as point estimates for both resting SBP and DBP were used to calculate true IIRD from each study and the inverse variance heterogeneity (IVhet) model was used to pool results.

RESULTS

For participants with essential hypertension, statistically significant and clinically important reductions in resting SBP (X̅, -18.2mmHg, 95% CI, -21.3 to -15.2mmHg) and DBP (X̅, -11.7mmHg, 95% CI, -17.0 to -6.3mmHg) were found. However, true IIRD were neither significant or clinically important for either SBP (X̅, -6.0mmHg, 95% CI, -9.1 to 3.5mmHg) or DBP (X̅, 2.8mmHg, 95% CI, -3.4 to 5.2mmHg). The 95% prediction interval for true IIRD was -11.9 to 8.4mmHg for SBP and -5.8 to 7.0mmHg for DBP.

CONCLUSIONS

While qigong is associated with reductions in resting SBP and DBP in adults with essential hypertension, a lack of true IIRD exists, suggesting that other external factors are responsible for any variation.

Effects of qigong on systolic and diastolic blood pressure lowering: a systematic review with meta-analysis and trial sequential analysis

BACKGROUND

The benefits of qigong for systolic and diastolic blood pressure (BP) reduction have been noted in previously published systematic reviews; however, the data on its effectiveness has been at best scarce. We aimed to update the evidence of qigong on blood pressure reduction after taking into consideration the risks of random error and reliability of data in the cumulative meta-analysis using trial sequential analysis (TSA).

METHODS

Included trials were assessed using Cochrane risk of bias instrument. We performed meta-analysis with random-effects model and random errors were evaluated with TSA. We performed the search for the eligible randomized controlled trial (RCT) through Medline, Cinahl, Cochrane Central Register of Controlled Trials and also PubMed.

RESULTS

A total of 370 subjects sourced from seven eligible RCTs were entered into the analysis. The pooled results demonstrated the significant reduction with the use of qigong of the systolic blood pressure [weighted mean difference (WMD), - 10.66 mmHg (95% confidence interval (CI) = - 17.69,-3.62, p < 0.001] and diastolic BP [WMD, - 6.76 mmHg, 95% CI = - 12.22, - 1.30, p < 0.001] as compared to the control group.

CONCLUSIONS

Significant reductions in BP is seen with the use of qigong as compared with the control group, suggesting that qigong may be used as a complementary therapy in the somewhat complicated management of hypertension.

The potency of education programs for management of blood pressure through increasing self-efficacy of hypertensive patients: A systematic review and meta-analysis

OBJECTIVE

To identify the effect of self-management education programs on the changes of self-efficacy and the management of blood pressure (BP) in hypertensive patients.

METHODS

PubMed, Google Scholar, Scopus, Trip database, Proquest, and Embase were searched. Trials that had examined the effect of self-management education programs on self-efficacy, systolic BP (SBP) and diastolic BP (DBP) in hypertensive patients were selected.

RESULTS

Fourteen studies with 2239 participants were analyzed. Self-management education programs led to a statistically-significant increase in the self-efficacy of the participants (SMD: 0.71; 95% CI: 0.34-1.07; I² = 94%; P < 0.001), as well as significant decrease in SBP (MD: -5.37 mmHg; 95% CI: -8.53 to -2.22; P < 0.001) and DBP (MD: -3.87 mmHg, 95% CI: -5.84 to -1.90; P < 0.001) compared to control groups.

CONCLUSION

The findings indicated that self-management education programs can promote self-efficacy in hypertensive patients, possibly contributing to better management of BP.

PRACTICE IMPLICATIONS

Adoption of the self-management education program provides a basic concept to improve both quality and efficacy of strategies related to BP management. Policy makers should focus on improving self-efficacy via the implementation of policies useful for better educational outcomes concerning new technologies as well as appropriate theoretical methods.

Qigong and Musculoskeletal Pain

PURPOSE OF REVIEW

Musculoskeletal pain is a widespread symptom that commonly produces considerable disability, particularly in later life. This brief review strove to summarize and critically review the recent research base concerning the use of Qigong as a possible strategy for alleviating longstanding or chronic musculoskeletal pain states.

METHODS

Research reports and literature reviews specifically focusing on Qigong and its impact on various forms of musculoskeletal pain between 2015 and 2019 were sought and analyzed, along with related data.

RESULTS

Collectively, these data reveal that while more research is indicated, Qigong practice may help to attenuate pain in varying degrees among adults with different forms of chronic pain with few side-effects.

CONCLUSION

More research is needed to ensure health professionals working with adults who have chronic unrelenting musculoskeletal pain may safely recommend these exercises as one possible remedy for reducing intractable musculoskeletal pain.

Efficacy of Tai Chi and qigong for the prevention of stroke and stroke risk factors: A systematic review with meta-analysis

BACKGROUND

This review aims to summarize the evidence of Tai Chi and qigong interventions for the primary prevention of stroke, including the effects on populations with major stroke risk factors.

METHODS

A systematic literature search was conducted on January 16, 2017 using the PubMed, Scopus, Cochrane Library, and CINAHL databases. Randomized controlled trials examining the efficacy of Tai Chi or qigong for stroke prevention and stroke risk factors were included. Risk of bias was assessed using the Cochrane Risk of Bias tool.

RESULTS

Twenty-one trials with n = 1604 patients with hypertension, hyperlipidaemia, diabetes, overweight or obesity, or metabolic syndrome were included. No trials were found that examined the effects of Tai Chi/qigong on stroke incidence. Meta-analyses revealed significant, but not robust, benefits of Tai Chi/qigong over no interventions for hypertension (systolic blood pressure: -15.55 mm Hg (95% CI: -21.16; -9.95); diastolic blood pressure: -10.66 mm Hg (95% CI: -14.90, -6.43); the homeostatic model assessment (HOMA) index (-2.86%; 95% CI: -5.35, -0.38) and fasting blood glucose (-9.6 mg/dL; 95% CI: -17.28, -1.91), and for the body mass index compared with exercise controls (-1.65 kg/m; 95% CI: -3.11, -0.20). Risk of bias was unclear or high for the majority of trials and domains, and heterogeneity between trials was high. Only 6 trials adequately reported safety. No recommendation for the use of Tai Chi/qigong for the prevention of stroke can be given.

CONCLUSION

Although Tai Chi and qigong show some potential more robust studies are required to provide conclusive evidence on the efficacy and safety of Tai Chi and qigong for reducing major stroke risk factors.

The Effect of Dongeui Qigong for Prehypertension and Mild Essential Hypertension

Although several previous studies have reported the effect of qigong on lowering blood pressure, rigorous trials are lacking. Studies evaluating the effect of qigong on prehypertension are also scarce. This study aimed to assess the effect of qigong on prehypertension and mild hypertension. Participants with prehypertension or mild hypertension were randomized to the Dongeui qigong group or a nontreated control group. In the qigong group, Dongeui qigong was administered 5 times/week for 12 weeks. The control group did not receive any intervention for blood pressure control. Fifty-two participants were included in this study. Even though diastolic blood pressure was significantly reduced in the qigong group after 8 weeks (p = 0.04) compared to baseline, the difference in change in blood pressure between the qigong and control groups was not significant. There were no significant differences in quality of life between the qigong and control groups. Dongeui qigong is not significantly effective in pre/mild hypertension compared with controls. This result could be due to a lack of effect of qigong or caused by other factors, such as the type of qigong, target symptoms, inappropriate sample size, and compliance of participants. Trial Registration. This trial is registered with KCT0001397 (Clinical Research Information Service).

Qigong Exercise and Arthritis

Background: Arthritis is a chronic condition resulting in considerable disability, particularly in later life. Aims: The first aim of this review was to summarize and synthesize the research base concerning the use of Qigong exercises as a possible adjunctive strategy for promoting well-being among adults with arthritis. A second was to provide related intervention directives for health professionals working or who are likely to work with this population in the future. Methods: Material specifically focusing on examining the nature of Qigong for minimizing arthritis disability, pain and dependence and for improving life quality was sought. Results: Collectively, despite almost no attention to this topic, available data reveal that while more research is indicated, Qigong exercises-practiced widely in China for many centuries as an exercise form, mind-body and relaxation technique-may be very useful as an intervention strategy for adults with different forms of painful disabling arthritis. Conclusion: Health professionals working with people who have chronic arthritis can safely recommend these exercises to most adults with this condition with the expectation they will heighten the life quality of the individual, while reducing pain and depression in adults with this condition.

The Effect of Three Different Meditation Exercises on Hypertension: A Network Meta-Analysis

We aimed to use the pairwise and network meta-analysis to estimate the effects of different meditation exercises on the control of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Randomized controlled trials (RCTs) were retrieved from PubMed and Embase up to June 2016, which are published in English and reported on meditation exercise for hypertensive patients. Risks of bias assessment of the included studies were assessed by Cochrane Collaboration Recommendations and network meta-analysis was performed by ADDIS. Mean difference (MD) and its 95% confidence interval (CI) were used as the effect size. A number of 19 RCTs were included in this study. Results of pairwise comparisons indicated that meditation exercise could significantly decrease the SBP and DBP, compared with other interventions (MD = −7.10, 95% CI: −10.82 to −3.39; MD = −4.02, 95% CI: −6.12 to −1.92). With good consistence and convergence, network meta-analysis showed that there were no significant differences between meditation and other interventions on SBP. For DBP, Qigong was significantly lower than “no intervention” (MD = −11.73, 95% CI: −19.85 to −3.69). Qigong may be the optimal exercise way in lowering SBP and DBP of hypertensive patients, but a detailed long-term clinical research should be needed in the future.

Qigong for hypertension: a systematic review

The purpose of this review was to evaluate the efficacy and safety of qigong for hypertension.A systematic literature search was performed in 7 databases from their respective inceptions until April 2014, including the Cochrane Library, EMBASE, PubMed, Chinese Scientific Journal Database, Chinese Biomedical Literature Database, Wanfang database, and Chinese National Knowledge Infrastructure. Randomized controlled trials of qigong as either monotherapy or adjunctive therapy with antihypertensive drugs versus no intervention, exercise, or antihypertensive drugs for hypertension were identified. The risk of bias was assessed using the tool described in Cochrane Handbook for Systematic Review of Interventions, version 5.1.0.Twenty trials containing 2349 hypertensive patients were included in the meta-analysis. The risk of bias was generally high. Compared with no intervention, qigong significantly reduced systolic blood pressure (SBP) (weighted mean difference [WMD] = -17.40 mm Hg, 95% confidence interval [CI] -21.06 to -13.74, P < 0.00001) and diastolic blood pressure (DBP) (WMD = -10.15 mm Hg, 95% CI -13.99 to -6.30, P < 0.00001). Qigong was inferior to exercise in decreasing SBP (WMD = 6.51 mm Hg, 95% CI 2.81 to 10.21, P = 0.0006), but no significant difference between the effects of qigong and exercise on DBP (WMD = 0.67 mm Hg, 95% CI -1.39 to 2.73, P = 0.52) was identified. Compared with antihypertensive drugs, qigong produced a clinically meaningful but not statistically significant reduction in SBP (WMD = -7.91 mm Hg, 95% CI -16.81 to 1.00, P = 0.08), but appeared to be more effective in lowering DBP (WMD = -6.08 mm Hg, 95% CI -9.58 to -2.58, P = 0.0007). Qigong plus antihypertensive drugs significantly lowered both SBP (WMD = -11.99 mm Hg, 95% CI -15.59 to -8.39, P < 0.00001) and DBP (WMD = -5.28 mm Hg, 95% CI, -8.13 to -2.42, P = 0.0003) compared with antihypertensive drugs alone. No serious adverse events were reported.The meta-analysis suggests that qigong is an effective therapy for hypertension. However, more rigorously designed randomized controlled trials with long-term follow-up focusing on hard clinical outcomes are required to confirm the results.

Traditional chinese medicine syndromes for essential hypertension: a literature analysis of 13,272 patients

Background. To simplify traditional Chinese medicine syndrome differentiation and allow researchers to master syndrome differentiation for hypertension, this paper retrospectively studied the literature and analyzed syndrome elements corresponding to hypertension syndromes. Methods. Six databases including PubMed, EMBASE, Chinese Bio-Medical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data were searched from 1/January/2003 to 30/October/2013. We included all clinical literature testing hypertension syndromes and retrospectively studied the hypertension literature published from 2003 to 2013. Descriptive statistics calculated frequencies and percentages. Results. 13,272 patients with essential hypertension were included. Clinical features of hypertension could be attributed to 11 kinds of syndrome factors. Among them, seven syndrome factors were excess, while four syndrome factors were deficient. Syndrome targets were mainly in the liver and related to the kidney and spleen. There were 33 combination syndromes. Frequency of single-factor syndromes was 31.77% and frequency of two-factor syndromes was 62.26%. Conclusions. Excess syndrome factors of hypertension patients include yang hyperactivity, blood stasis, phlegm turbidity, internal dampness, and internal fire. Deficient syndrome factors of hypertension patients are yin deficiency and yang deficiency. Yin deficiency with yang hyperactivity, phlegm-dampness retention, and deficiency of both yin and yang were the three most common syndromes in clinical combination.

Yoga for essential hypertension: a systematic review

BACKGROUND

Yoga is thought to be effective for health conditions. The article aims to assess the current clinical evidence of yoga for Essential hypertension (EH).

STRATEGY

MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library were searched until June, 2013. We included randomized clinical trials testing yoga against conventional therapy, yoga versus no treatment, yoga combined with conventional therapy versus conventional therapy or conventional therapy combined with breath awareness. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards.

RESULTS

A total of 6 studies (involving 386 patients) were included. The methodological quality of the included trials was evaluated as generally low. A total of 6 RCTs met all the inclusion criteria. 4 of them compared yoga plus conventional therapy with conventional therapy. 1 RCT described yoga combined with conventional therapy versus conventional therapy combined with breath awareness. 2 RCT tested the effect of yoga versus conventional therapy alone. 1 RCT described yoga compared to no treatment. Only one trial reported adverse events without details, the safety of yoga is still uncertain.

CONCLUSIONS

There is some encouraging evidence of yoga for lowering SBP and DBP. However, due to low methodological quality of these identified trials, a definite conclusion about the efficacy and safety of yoga on EH cannot be drawn from this review. Therefore, further thorough investigation, large-scale, proper study designed, randomized trials of yoga for hypertension will be required to justify the effects reported here.

Tai chi for essential hypertension

Objectives. To assess the current clinical evidence of Tai Chi for essential hypertension (EH). Search Strategy. 7 electronic databases were searched until 20 April, 2013. Inclusion Criteria. We included randomized trials testing Tai Chi versus routine care or antihypertensive drugs. Trials testing Tai Chi combined with antihypertensive drugs versus antihypertensive drugs were also included. Data Extraction and Analyses. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. Results. 18 trials were included. Methodological quality of the trials was low. 14 trials compared Tai Chi with routine care. 1 trial compared Tai Chi with antihypertensive drugs. Meta-analysis all showed significant effect of TaiChi in lowering blood pressure (BP). 3 trials compared Tai Chi plus antihypertensive drugs with antihypertensive drugs. Positive results in BP were found in the other 2 combination groups. Most of the trials did not report adverse events, and the safety of Tai Chi is still uncertain. Conclusions. There is some encouraging evidence of Tai Chi for EH. However, due to poor methodological quality of included studies, the evidence remains weak. Rigorously designed trials are needed to confirm the evidence.

Trends in the treatment of hypertension from the perspective of traditional chinese medicine

Hypertension is a major public-health issue. Much consensus has been reached in the treatment, and considerable progress has been made in the field of antihypertensive drugs. However, the standard-reaching rate of blood pressure is far from satisfaction. Considering these data and the seriousness of the effects of hypertension on the individual and society as a whole, both economically and socially, physicians must look for more effective and alternative ways to achieve the target blood pressure. Could treatment of hypertension be improved by insights from traditional Chinese medicine? As one of the most important parts in complementary and alternative therapies, TCM is regularly advocated for lowering elevated blood pressure. Due to the different understanding of the pathogenesis of hypertension between ancient and modern times, new understanding and treatment of hypertension need to be reexplored. Aiming to improve the efficacy of Chinese herbal medicine in treating hypertension, the basis of treatment is explored through systematically analyzing the literature available in both English and Chinese search engines. This paper systematically reviews the trends in emerging therapeutic strategies for hypertension from the perspective of traditional Chinese medicine.

Evidence-based chinese medicine for hypertension

Hypertension is an important worldwide public -health challenge with high mortality and disability. Due to the limitations and concerns with current available hypertension treatments, many hypertensive patients, especially in Asia, have turned to Chinese medicine (CM). Although hypertension is not a CM term, physicians who practice CM in China attempt to treat the disease using CM principles. A variety of approaches for treating hypertension have been taken in CM. For seeking the best evidence of CM in making decisions for hypertensive patients, a number of clinical studies have been conducted in China, which has paved the evidence-based way. After literature searching and analyzing, it appeared that CM was effective for hypertension in clinical use, such as Chinese herbal medicine, acupuncture, moxibustion, cupping, qigong, and Tai Chi. However, due to the poor quality of primary studies, clinical evidence is still weak. The potential benefits and safety of CM for hypertension still need to be confirmed in the future with well-designed RCTs of more persuasive primary endpoints and high-quality SRs. Evidence-based Chinese medicine for hypertension still has a long way to go.

Chinese herbal formulas for treating hypertension in traditional Chinese medicine: perspective of modern science

Hypertension, which directly threatens quality of life, is a major contributor to cardiovascular and cerebrovascular events. Over the past two decades, domestic and foreign scholars have agreed upon various standards in the treatment of hypertension, and considerable progress has been made in the field of antihypertensive drugs. Oral antihypertensive drugs represent a milestone in hypertension therapy. However, the blood pressure standard for patients with hypertension is far from satisfactory. The study of Chinese herbal formulas for treating hypertension has received much research attention. These studies seek to integrate traditional and Western medicine in China. Currently, Chinese herbal formulas are known to have an outstanding advantage with regard to bodily regulation. Research shows that Chinese medicine has many protective mechanisms. This paper addresses the process of the antihypertensive mechanisms in Chinese herbal formulas for treating hypertension. These mechanisms are to be discussed in future research.

The effects of qigong on anxiety, depression, and psychological well-being: a systematic review and meta-analysis

Introduction. The effect of Qigong on psychological well-being is relatively unknown. This study systematically reviewed the effects of Qigong on anxiety, depression, and psychological well-being. Methods. Using fifteen studies published between 2001 and 2011, a systematic review was carried out and meta-analyses were performed on studies with appropriate homogeneity. The quality of the outcome measures was also assessed. Results. We categorized these studies into three groups based on the type of subjects involved as follows: (1) healthy subjects, (2) subjects with chronic illnesses, and (3) subjects with depression. Based on the heterogeneity assessment of available studies, meta-analyses were conducted in three studies of patients with type II diabetes in the second group, which suggested that Qigong was effective in reducing depression (ES = −0.29; 95% CI, −0.58–0.00) and anxiety (ES = −0.37; 95% CI, −0.66–0.08), as measured by Symptom Checklist 90, and in improving psychological well-being (ES = −0.58; 95% CI, −0.91–0.25) as measured by Diabetes Specific Quality of Life Scale. Overall, the quality of research methodology of existing studies was poor. Conclusions. Preliminary evidence suggests that Gigong may have positive effects on psychological well-being among patients with chronic illnesses. However the published studies generally had significant methodological limitations. More high-quality studies are needed.

Banxia baizhu tianma decoction for essential hypertension: a systematic review of randomized controlled trials

Objectives. To assess the current clinical evidence of Banxia Baizhu Tianma Decoction (BBTD) for essential hypertension (EH). Search Strategy. Electronic databases were searched until July 2012. Inclusion Criteria. We included randomized clinical trials testing BBTD against placebo, antihypertensive drugs, or combined with antihypertensive drugs against antihypertensive drugs. Data Extraction and Analyses. Study selection, data extraction, quality assessment, and data analyses were conducted according to Cochrane standards. Results. 16 randomized trials were included. Methodological quality of the included trials was evaluated as generally low. 2 trials compared prescriptions based on BBTD using alone with antihypertensive drugs. Meta-analysis showed no significant effect of modified BBTD compared with captopril in systolic blood pressure (MD: -0.75 (-5.77, 4.27); P = 0.77) and diastolic blood pressure (MD: -0.75 (-2.89, 1.39); P = 0.49). 14 trials compared the combination of BBTD or modified BBTD plus antihypertensive drugs with antihypertensive drugs. Meta-analysis showed there are significant beneficial effect on systolic blood pressure in the combination group compare to the antihypertensive drugs (MD: -4.33 (-8.44, -0.22); P = 0.04). The safety of BBTD is uncertain. Conclusions. There is encouraging evidence of BBTD for lowering SBP, but evidence remains weak. Rigorously designed trials are warranted to confirm these results.

A trial for the use of qigong in the treatment of pre and mild essential hypertension: a study protocol for a randomized controlled trial

Background

Hypertension is a risk factor for cardiovascular disease, and the prevalence of hypertension tends to increase with age. Current treatments for hypertension have side effects and poor adherence. Qigong has been studied as an alternative therapy for hypertension; however, the types of qigong used in those studies were diverse, and there have not been many well-designed randomized controlled trials.

Our objectives are the following: 1) To evaluate the effects of qigong on blood pressure, health status and hormone levels for pre- or mild hypertension. 2) To test the methodological appropriateness of this clinical trial and calculate a sample size for future randomized trials.

Methods

Forty subjects with pre- or mild hypertension will be randomized to either the qigong exercise group or the non-treated group. Participants in the qigong group will conduct qigong exercises 5 times per week for 8 weeks, and participants in the non-treated group will maintain their current lifestyle, including diet and exercise. The use of antihypertensive medication is not permitted. The primary endpoint is a change in patient blood pressure. Secondary endpoints are patient health status (as measured by the SF-36 and the MYMOP2 questionnaires) and changes in hormone levels, including norepinephrine, epinephrine, and cortisol.

Discussion

This study will be the first randomized trial to investigate the effectiveness of qigong exercises for the treatment of pre- and mild hypertension. The results of this study will help to establish the optimal approach for the care of adults with pre- or mild hypertension.

[Physical exercise in patients with high-blood pressure: a conceptual analysis]

In the treatment of arterial hypertension, physical exercises have been appointed as one of the main non-pharmacological measures. This study aims to analyze the concept of physical exercise in patients with hypertension and identify possible critical attributes and preceding and consequent factors. The study followed the conceptual analysis methodology and the integrative revision of scientific articles related to the topic. As to critical attributes, aspects related to time, frequency, duration and intensity of physical exercise were identified. The preceding factors found were: advice/education, motivation, goal development from Transtheoretical Model, self-efficacy and support groups. Regarding the consequent factors, general health benefits were evidenced as physiological, psychosocial, cognitive and behavioral benefits. The conceptual analysis supports quality assistance centered in the patient with hypertension, aiming the control of the disease and the prevention of complications.

Effectiveness of Qigong in Promoting the Health of Wheelchair-Bound Older Adults in Long-Term Care Facilities

Institutional wheelchair-bound older adults often do not get regular exercise and are prone to health problems. The aim of this study was to test the effects of a 12-week qigong exercise program on the physiological and psychological health of wheelchair-bound older adults in long-term care facilities. Study design was quasi-experimental, pre–post test, nonequivalent control group. Participants comprised a convenience sample of 72 wheelchair-bound older adults (qigong = 34; control = 38). The qigong group exercised 35 min/day, 5 days/week for 12 weeks. Measures for physical health (blood pressure, heart rate variability, and distal skin temperature) and psychological health (Brief Symptom Rating Scale-5) were collected before and during study Weeks 4, 8, and 12. The qigong group participants’ blood pressure, distal skin temperature, and psychological health were significantly improved (all p < .001). These findings suggest that qigong exercise is a suitable daily activity for elderly residents in long-term care facilities and may help in the control of blood pressure among older adults.

A comprehensive review of health benefits of qigong and tai chi

OBJECTIVE

Research examining psychological and physiological benefits of Qigong and Tai Chi is growing rapidly. The many practices described as Qigong or Tai Chi have similar theoretical roots, proposed mechanisms of action, and expected benefits. Research trials and reviews, however, treat them as separate targets of examination. This review examines the evidence for achieving outcomes from randomized controlled trials (RCTs) of both.

DATA SOURCES

The key words Tai Chi, Taiji, Tai Chi Chuan, and Qigong were entered into electronic search engines for the Cumulative Index for Allied Health and Nursing (CINAHL), psychological literature (PsycINFO), PubMed, Cochrane database, and Google Scholar. STUDY INCLUSION CRITERIA: RCTs reporting on the results of Qigong or Tai Chi interventions and published in peer-reviewed journals from 1993 to 2007.

DATA EXTRACTION

Country, type and duration of activity, number/type of subjects, control conditions, and reported outcomes were recorded for each study.

SYNTHESIS

Outcomes related to Qigong and Tai Chi practice were identified and evaluated.

RESULTS

Seventy-seven articles met the inclusion criteria. The nine outcome category groupings that emerged were bone density (n = 4), cardiopulmonary effects (n = 19), physical function (n = 16), falls and related risk factors (n = 23), quality of life (n = 17), self-efficacy (n = 8), patient-reported outcomes (n = 13), psychological symptoms (n = 27), and immune function (n = 6).

CONCLUSIONS

Research has demonstrated consistent, significant results for a number of health benefits in RCTs, evidencing progress toward recognizing the similarity and equivalence of Qigong and Tai Chi.

The sociology of Qi Gong: a qualitative study

This paper presents an in-depth, idiographic study of how individuals experience others during Qi Gong practice. Semi-structured interviews were conducted with three Qi Gong groups to collect research data. These data were transcribed verbatim and subjected to content and thematic analysis across and within groups. The analysis indicates extraordinary experiences of Qi Gong practitioners at various levels of their social functioning. Qi Gong influences their social health in complex and \dimensional ways. The author compares and contrasts his results with those of recent research. Implications for practice are briefly outlined and possible strategies for future research are presented.

Correlates of self-care behaviors for managing hypertension among Korean Americans: a questionnaire survey

BACKGROUND

While self-care behaviors have been documented as one of the main determinant of hypertension control, studies investigating correlates of self-care behaviors have been rare regarding hypertension among minority population.

OBJECTIVES

The purpose of this study was to examine factors associated with self-care behaviors for hypertension using a community sample of Korean Americans.

DESIGN

A descriptive cross-sectional design.

SETTINGS

Community setting in the Baltimore-Washington metropolitan area.

PARTICIPANTS

The sample included 445 middle-aged (40-64 years of age) Korean Americans with hypertension (systolic BP > or = 140 and/or diastolic BP > or = 90 mmHg; or taking antihypertensive medication).

METHODS

Guided by Social Cognitive Theory, a variety of personal (age, gender, marital status, employment status, years in U.S., duration of hypertension, hypertension knowledge, hypertension belief, and hypertension control self-efficacy) and environmental (social support) factors were examined in relation to hypertension self-care behaviors, including medication-taking, exercise, diet, and weight control.

RESULTS

The model explained 18.0% of the total variance in self-care scores. Hierarchical multiple regression revealed that personal factors contributed significantly to the explanatory model, whereas social support did not add much. Examination of individual regression coefficients showed that Korean Americans who were older, who had longer duration of hypertension, and who had higher hypertension control self-efficacy were more likely to have higher self-care scores.

CONCLUSIONS

Hypertension control self-efficacy emerged as the most significant contributing factor to hypertension self-care. Future intervention programs should focus on improving hypertension control self-efficacy as a modifiable personal factor.

Biopsychosocial effects of qigong as a mindful exercise for people with anxiety disorders: a speculative review

In view of the inadequacies of mainstream treatments for anxiety disorders, we suggest that qigong, an ancient oriental mindful exercise, may be a useful adjunctive treatment. We base this on a biopsychosocial model for health. Evidence suggests that the benefits of exercise on personal well-being can be explained using six theories: cognitive behaviour; distraction; social interaction; cardiovascular fitness; amine; and endorphin theories. To date, not much has been done to employ these theories to analyze the benefits of mindful exercises. We try here to reorganize these theories into psychosocial and physiologic perspectives and integrate them with the "mind regulation," "body regulation," and "breath regulation" components of qigong. We propose, because of its potential therapeutic effects, that qigong can be considered as an alternative therapy to help meet the increasing demand of nonpharmacologic modalities in achieving biopsychosocial health for those suffering from anxiety in the general population.

Relaxation therapies for the management of primary hypertension in adults

BACKGROUND

Lifestyle interventions are often recommended as initial treatment for mild hypertension, but the efficacy of relaxation therapies is unclear.

OBJECTIVES

To evaluate the effects of relaxation therapies on cardiovascular outcomes and blood pressure in people with elevated blood pressure.

SEARCH STRATEGY

We searched the Cochrane Library, MEDLINE, EMBASE, Science Citation Index, ISI Proceedings, ClinicalTrials.gov, Current Controlled Trials and reference lists of systematic reviews, meta-analyses and randomised controlled trials (RCTs) included in the review.

INCLUSION CRITERIA

RCTs of a parallel design comparing relaxation therapies with no active treatment, or sham therapy; follow-up >/=8 weeks; participants over 18 years, with raised systolic blood pressure (SBP) >/=140 mmHg or diastolic blood pressure (DBP) >/=85 mmHg); SBP and DBP reported at end of follow-up.

EXCLUSION CRITERIA

participants were pregnant; participants received antihypertensive medication which changed during the trial.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed trial quality. Disagreements were resolved by discussion or a third reviewer. Random effects meta-analyses and sensitivity analyses were conducted.

MAIN RESULTS

29 RCTs, with eight weeks to five years follow-up, met our inclusion criteria; four were excluded from the primary meta-analysis because of inadequate outcome data. The remaining 25 trials assessed 1,198 participants, but adequate randomisation was confirmed in only seven trials and concealment of allocation in only one. Only one trial reported deaths, heart attacks and strokes (one of each). Meta-analysis indicated that relaxation resulted in small, statistically significant reductions in SBP (mean difference: -5.5 mmHg, 95% CI: -8.2 to -2.8, I2 =72%) and DBP (mean difference: -3.5 mmHg, 95% CI: -5.3 to -1.6, I2 =75%) compared to control. The substantial heterogeneity between trials was not explained by duration of follow-up, type of control, type of relaxation therapy or baseline blood pressure. The nine trials that reported blinding of outcome assessors found a non-significant net reduction in blood pressure (SBP mean difference: -3.2 mmHg, 95% CI: -7.7 to 1.4, I(2) =69%) associated with relaxation. The 15 trials comparing relaxation with sham therapy likewise found a non-significant reduction in blood pressure (SBP mean difference: -3.5 mmHg, 95% CI: -7.1 to 0.2, I(2) =63%).

AUTHORS' CONCLUSIONS

In view of the poor quality of included trials and unexplained variation between trials, the evidence in favour of causal association between relaxation and blood pressure reduction is weak. Some of the apparent benefit of relaxation was probably due to aspects of treatment unrelated to relaxation.
