Effects of Qi-therapy on blood pressure, pain and psychological symptoms in the elderly: a randomized controlled pilot trial

The use of biofield energy therapy as complementary and alternative medicine in human health care system: a narrative review and potential mechanisms

INTRODUCTION

There has been accumulating interest in the application of biofield therapy as complementary and alternative medicine (CAM) to treat various diseases. The practices include reiki, qigong, blessing, prayer, distant healing, known as biofield therapies. This paper aims to state scientific knowledge on preclinical and clinical studies to validate its potential use as an alternative medicine in the clinic. It also provides a more in-depth context for understanding the potential role of quantum entanglement in the effect of biofield energy therapy.

CONTENT

A comprehensive literature search was performed using the different databases (PubMed, Scopus, Medline, etc.). The published English articles relevant to the scope of this review were considered. The review gathered 45 papers that were considered suitable for the purpose. Based on the results of these papers, it was concluded that biofield energy therapy was effective in treating different disease symptoms in preclinical and clinical studies.

SUMMARY

Biofield therapies offer therapeutic benefits for different human health disorders, and can be used as alternative medicine in clinics for the medically pluralistic world due to the growing interest in CAM worldwide.

OUTLOOK

The effects of the biofield energy therapies are observed due to the healer's quantum thinking, and transmission of the quantum energy to the subject leads to the healing that occurs spiritually through instantaneous communication at the quantum level via quantum entanglement.

Understanding Traditional Chinese Medicine Therapeutics: An Overview of the Basics and Clinical Applications

Traditional Chinese medicine (TCM) is a systematic healthcare system developed from clinical experience based on a scientific model of regulation. TCM relies on unique theories and practices to treat diseases and enhance health. These practices include Chinese herbal medicine and dietetics, acupuncture and moxibustion, and other non-medication therapies such as Chinese bodywork or manual therapy, known as "Tuina", and traditional biofeedback exercises, known as "Qigong" and "Taijiquan". The integration of TCM in Western health systems and research requires a rational communicable theory, scientific proof of efficacy and safety, and quality control measures. Understanding the structural concepts of the TCM language makes possible the parallelism to Western physiology, and the inherent rational use of the reflex therapeutic systems, anti-inflammatory mechanisms and mental training involved, for example, in acupuncture and "Qigong". The results of TCM clinical trials and fundamental research on its nature and mechanisms have encouraged the development and application of well-designed research strategies such as double blinding in acupucture to overcome limitations and resistances in integrating these practices into the existing biomedical paradigms of the West. This review aims to overview some TCM theoretical concepts and the evidence-based clinical application of TCM's leading practices to create an easy-to-consult and condensed source of information, available for the healthcare community, facilitating the understanding and communication between conventional health professionals and TCM practitioners and acupuncturists.

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.

Amelioration of mild and moderate depression through Pranic Healing as adjuvant therapy: randomised double-blind controlled trial

OBJECTIVES

Depression is a mental disorder, affecting the quality of life. Our study explores the efficacy of Pranic Healing (PH), as an adjuvant therapy in treating depression Methods: In this randomised double-blind controlled trial, 52 participants with a mean age of 34.4 years, with mild to moderate depression were assessed using the Hamilton Depression Rating (HAM-D) scale during the 5-week study. Both Medication + PH (MedPH) and Medication + Mock PH (MedMockPH) groups comprising 26 members received Pranic and mock healing lasting 20 minutes per session respectively once a week for 4 weeks, along with the antidepressant drug.

RESULTS

The average decrease in HAM-D score in MedPH was median 11 (Interquartile Range (IQR) 7-12) and was significantly higher compared with the MedMockPH group median 6.5 (IQR 3-9). At pre-assessment, both groups had 8 cases of mild and 18 cases of moderate depression. At post-assessment, HAM-D showed that the improvement in depression category was seen in 69.2% of participants in the MedMockPH group and 100% in MedPH group.

CONCLUSIONS

These results give first the evidence that PH can aid as an adjuvant therapy for depressed people.

The Effects of Qigong for Adults with Chronic Pain: Systematic Review and Meta-Analysis

A systematic review was conducted to evaluate the effectiveness of qigong as a treatment for chronic pain. Five electronic databases were searched from their date of establishment until July 2014. The review included 10 randomized clinical trials (RCTs) that compared the impacts of qigong on chronic pain with waiting list or placebo or general care. Random effect models and standard mean differences were used to present pain scores. A total of 10 RCTs met inclusion criteria. There was a statistically significant difference on reducing chronic pain between internal qigong and control (SMD: -1.23 95% CI= -2.23, -0.24p = 0.02), external qigong and general care (SMD: -1.53 95% CI= -2.15, -0.91p < 0.05), external qigong and placebo (SMD: -0.51 95% CI = 0.95, -0.06p = 0.03), and internal qigong for chronic neck pain at 6 months (SMD: -1.00 95% CI= -1.94, -0.06p = 0.04). The differences between external qigong and control, external qigong and waiting list, internal qigong and waiting list, and external for premenstrual syndromes were not significant. This study showed that internal qigong generated benefits on treating some chronic pain with significant differences. External qigong showed nonsignificant differences in treating chronic pain. Higher quality randomized clinical trials with scientific rigor are needed to establish the effectiveness of qigong in reducing chronic pain.

Nontouch biofield therapy: a systematic review of human randomized controlled trials reporting use of only nonphysical contact treatment

OBJECTIVE AND CONTEXT: This review was designed to assess the quality and review the outcomes of randomized controlled trials (RCTs) of biofield therapies (external qigong, Healing Touch, Johrei, Reiki, and Therapeutic Touch) that report using only nonphysical touch forms of treatment. RCTs of nonphysical contact biofield therapies have the potential to contribute to an evidence base for health-promoting effects mediated through mechanisms outside the present understanding of biomedicine.

METHODS

Articles meeting inclusion criteria were identified from database and reference list searches and evaluated for a range of reporting and design items. Data were extracted to determine the range of protocol parameters and treatment outcomes. The final set of included RCTs were evaluated via a modified 5-item Jadad scale as well as by a set of 20 criteria that included items relevant to the early-phase nature of the trials and to the examination of nonphysical touch biofield therapy interventions.

RESULTS

Of 90 RCTs that assessed effectiveness of a biofield therapy in humans, 28 trials involving 1775 participants met additional inclusion criteria (most importantly a clearly reported use of only nonphysical contact treatment). The research designs of these 28 trials revealed marked heterogeneity in regard to condition treated, number and duration of treatments, nature of the control/comparison group, and outcome measures. Finally, 10 trials were excluded on the basis of low quality assessment scores. Twelve of the remaining 18 trials (7 Therapeutic Touch, 3 external qigong, 1 Reiki, and 1 Healing Touch) reported at least one primary outcome with statistically significant beneficial treatment outcomes.

CONCLUSIONS

The pilot study nature of essentially all the identified nonphysical contact biofield therapy RCTs, as reflected by low sample sizes alone, precludes drawing robust conclusions. Given this perspective, the finding that two thirds of the higher-scoring trials demonstrated at least partial effectiveness favors a continued research effort, especially in light of the translational value of biofield clinical trials for studies exploring the nature and physiologic basis of biofield healing.

Qigong for the primary prevention of cardiovascular disease

BACKGROUND

Two major determinants of cardiovascular disease (CVD) are a sedentary lifestyle and stress. Qigong involves physical exercise, mind regulation and breathing control to restore the flow of Qi (a pivotal life energy). As it is thought to help reduce stress and involves exercise, qigong may be an effective strategy for the primary prevention of CVD.

OBJECTIVES

To determine the effectiveness of qigong for the primary prevention of CVD.

SEARCH METHODS

We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (November 2014, Issue 10 of 12); MEDLINE (Ovid) (1946 to 2014 October week 4); EMBASE Classic + EMBASE (Ovid) (1947 to 2014 November 4); Web of Science Core Collection (1970 to 31 October 2014); Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database and Health Economics Evaluations Database (November 2014, Issue 4 of 4). We searched several Asian databases (inception to July 2013) and the Allied and Complementary Medicine Database (AMED) (inception to December 2013), as well as trial registers and reference lists of reviews and articles; we also approached experts in the field and applied no language restrictions in our search.

SELECTION CRITERIA

Randomised controlled trials lasting at least three months involving healthy adults or those at high risk of CVD. Trials examined any type of qigong, and comparison groups provided no intervention or minimal intervention. Outcomes of interest included clinical CVD events and major CVD risk factors. We did not include trials that involved multi-factorial lifestyle interventions or weight loss.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion. Two review authors extracted data from included studies and assessed the risk of bias.

MAIN RESULTS

We identified 11 completed trials (1369 participants) and one ongoing trial. Trials were heterogeneous in participants recruited, qigong duration and length of follow-up periods. We were unable to ascertain the risk of bias in nine trials published in Chinese, as insufficient methodological details were reported and we were unable to contact the study authors to clarify this.We performed no meta-analyses, as trials were small and were at significant risk of bias. Clinical events were detailed in subsequent reports of two trials when statistically significant effects of qigong were seen for all-cause mortality, stroke mortality and stroke incidence at 20 to 30 years after completion of the trials. However, these trials were designed to examine outcomes in the short term, and it is not clear whether qigong was practised during extended periods of follow-up; therefore effects cannot be attributed to the intervention. None of the included studies reported other non-fatal CVD events.Six trials provided data that could be used to examine the effects of qigong on blood pressure. Reductions in systolic blood pressure (SBP) and diastolic blood pressure (DBP) were seen in three and two trials, respectively. Three trials examined the effects of qigong on blood lipids when favourable effects were seen in one trial for total cholesterol, low-density lipoprotein (LDL) cholesterol and triglycerides, and two trials showed favourable effects on high-density lipoprotein (HDL) cholesterol. The only trial considered at low risk of selection and detection bias did not demonstrate statistically significant effects on CVD risk factors with qigong, but this study was small and was underpowered. None of the included studies reported incidence of type 2 diabetes (T2D), adverse events, quality of life or costs.

AUTHORS' CONCLUSIONS

Currently, very limited evidence is available on the effectiveness of qigong for the primary prevention of CVD. Most of the trials included in this review are likely to be at high risk of bias, so we have very low confidence in the validity of the results. Publication of the ongoing trial will add to the limited evidence base, but further trials of high methodological quality with sufficient sample size and follow-up are needed to be incorporated in an update of this review before the effectiveness of qigong for CVD prevention can be established.

Qigong as a Traditional Vegetative Biofeedback Therapy: Long-Term Conditioning of Physiological Mind-Body Effects

A contemporary understanding of Chinese Medicine (CM) regards CM diagnosis as a functional vegetative state that may be treated by vegetative reflex therapies such as acupuncture. Within this context, traditional mind-body exercises such as Qigong can be understood as an attempt to enhance physiological proprioception, by combining a special state of “awareness” with posture, movement, and breath control. We have formerly trained young auditing flutists in “White Ball” Qigong to minimize anxiety-induced cold hands and lower anxiety-induced heart rate. Functional changes occurred 2–5 min after training and were observed over the whole training program, allowing the children to control their symptoms. In our current work, we report that warm fingers and calm hearts could be induced by the children even without Qigong exercises. Thus, these positive changes once induced and “conditioned” vegetatively were stable after weeks of training. This may show the mechanism by which Qigong acts as a therapeutic measure in disease: positive vegetative pathways may be activated instead of dysfunctional functional patterns. The positive vegetative patterns then may be available in critical stressful situations. Qigong exercise programs may therefore be understood as an ancient vegetative biofeedback exercise inducing positive vegetative functions which are added to the individual reactive repertoire.

Qigong program on insomnia and stress in cancer patients: A case series report

Background:

In recent years, the interest in Qigong as an alternative therapy has grown following reports of its ability to regulate psychological factors in cancer patients. This is a case series to evaluate the outcome measures of Qigong when used as an adjunct to standard medical care to treat insomnia and stress in cancer patients.

Patients and methods:

The Qigong program was applied to four cancer patients with insomnia, stress, and anxiety. The program consisted of 30-min sessions involving exercise, patting of the 12 meridians, and spontaneous breathing exercises three times a week for a period of 4 weeks. The Pittsburgh Sleep Quality Index was measured as the primary outcome, while the Stress Scale, the State–Trait Anxiety Inventory, and the Functional Assessment Cancer Therapy–General determined the secondary outcomes. Insomnia, stress, and anxiety levels were examined weekly, while quality of life was examined on the first visit and the last visit.

Results:

The Pittsburgh Sleep Quality Index and Stress Scale scores were reduced after conduct of the Qigong program.

Conclusion:

This study could provide a better understanding of Qigong’s influence on insomnia and stress in cancer patients. However, a larger controlled trial should be conducted to confirm these findings.

Beneficial Effects of Pranic Meditation on the Mental Health and Quality of Life of Breast Cancer Survivors

Background. Breast cancer survivors frequently present long-lasting impairments, caused either by the disease or its treatment, capable of compromising their emotional health and quality of life. Meditation appears to be a valuable complementary measure for overcoming some of these impairments. The purpose of the present investigation was to assess the effect of pranic meditation on the quality of life and mental health of breast cancer survivors. Design. This study was a prospective single-arm observational study using before and after measurements. Methods. The subjects were 75 women submitted either to breast cancer therapy or to posttherapy control who agreed to practice pranic meditation for 20 minutes, twice a day, during 8 weeks, after receiving a formal training. The quality of life of the practitioners was assessed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC BR-023 questionnaires, and the mental health status by the Goldberg’s General Health Questionnaire. Results. After 8 weeks of pranic meditation practice, the subjects showed a significant improvement of their quality of life scores that included physical ( P = .0007), role ( P = .01), emotional ( P = .002), and social functioning ( P = .004), as well as global health status ( P = .005), fatigue ( P < .0001), pain ( P = .007), sleep disturbances ( P = .01), body image ( P = .001), arm symptoms ( P = .007), and breast symptoms ( P = .002). They also showed a reduction of the side effects of systemic therapy ( P = .02) and being upset by hair loss ( P = .02). Moreover, meditation was associated with improvement of the mental health parameters of the practitioners that included psychic stress ( P = .001), death ideation ( P = .02), performance diffidence ( P = .001), psychosomatic disorders ( P = .02), and severity of mental disorders ( P = .0003). The extension of the meditation period from 8 to 15 weeks caused no substantial extra benefits in practitioners. Conclusions. The results of this pilot study showed that breast cancer survivors presented significant benefits related to their mental health and quality of life scores after a short period of practice of pranic meditation, consisting of simple and easy-to-learn exercises. However, because of the limitations of the study, further research is required using a more rigorous experimental design to ascertain whether pranic meditation may be an acceptable adjunct therapy for cancer patients.

Effect of biofield therapy in the human brain

OBJECTIVES

The effects of Okada Purifying Therapy (OPT), a form of subtle energy (biofield) therapy that originated in Japan, were investigated. Electroencephalograms and the Profile of Mood States scores were measured using a crossover design during OPT and placebo sessions.

PARTICIPANTS

Nineteen (19) healthy Japanese adults (mean age±standard deviation: 40.8±11.2 years; 10 females) with no previous experience of biofield therapy participated in this study.

METHODS

Each session lasted 15 minutes. A single-blind, randomized design with a protocol consisting of regular cycles with eyes open followed by eyes closed was used. The power spectral value was calculated in θ (4.0-7.9 Hz), α (8.0-12.9 Hz), and β (13.0-29.9 Hz) frequency ranges.

RESULTS

The power spectral value of the α band at F(p1), F(p2), F(7), F(z), F(8), C(3), C(z), C(4), and P(z) increased significantly in the OPT session compared with the placebo session. Mood state was improved after both sessions, and no significant difference was found between the two sessions.

CONCLUSIONS

OPT was more effective in increasing α waves in the frontal and central cortex than a placebo treatment.

Qi Therapy (External Qigong) for Chronic Fatigue Syndrome: Case Studies

The aim of this study was to examine the effects of Qi therapy (QT) on the symptoms of chronic fatigue syndrome (CFS), including fatigue and complications. QT affected the experience of mental and emotional relaxation in the subjects of these case studies, who also gained strength to overcome their pain and fatigue. Although the results of these two case studies may not constitute conclusive evidence, they provide a foundation for the exploration of QT as a complementary therapy in the reduction of negative symptoms of chronic fatigue syndrome.

Nonlinear Analysis of Heart Rate Variability During Qi Therapy (External Qigong)

Heart rate variability (HRV) was compared in 30 subjects receiving external Qi therapy (EQT) or placebo control therapy, in a crossover design experiment. Subjects who received the EQT reported more pleasant and calm emotions than did the placebo group. Qi therapy reduced the heart rate and increased HRV as indicated by a reduced low frequency/high frequency power ratio of HRV. With nonlinear analysis, the Poincaré plot index of HRV and approximate entropy was greater in the EQT group than in the control group. These findings suggest that EQT stabilizes the sympathovagal function and cardiac autonomic nervous system by inducing more positive emotions than the placebo therapy. In conclusion, EQT may act by stabilizing both the autonomic nervous system and the emotional state.

External qigong therapy for women with breast cancer prior to surgery

The majority of patients with cancer use some form of complementary or alternative medicine. External qigong treatment (EQT), classified as a bioenergy therapy, is one such approach that patients combine with conventional medicine or, in some cases, use in place of conventional medicine. This study aimed to determine whether EQT could shrink breast cancer tumors and improve quality of life (QOL) in women with pathologically confirmed breast cancer awaiting surgery. A total of 9 women with pathologically confirmed breast cancer were recruited from large cancer centers in the United States (n = 5) and China (n = 4). A single-arm pre/post design was used. Each patient underwent 5 consecutive days of EQT, with each treatment lasting from 2 to 5 minutes. All treatments were performed by the same qigong master. Tumor measurements were made before and after the EQT sessions. Tumor assessments were conducted prior to study initiation and following the last EQT. Patients underwent both an ultrasound and mammogram (United States) or an ultrasound and magnetic resonance imaging (China). All patients also underwent physical breast examinations (PBEs) and completed QOL questionnaires before and after the last EQT. No clinical changes in tumor measurements from pre- to post-EQT were noted. There was also no suggestion of change in tumor size by PBE or change in QOL. Using the current

STUDY DESIGN

EQT also does not appear to have any effect on patient QOL. Because of the small sample size and working with only one qigong practitioner, to definitively determine the efficacy or lack of efficacy of EQT, a larger study with multiple qigong practitioners would need to be conducted.

Biofield therapies: helpful or full of hype? A best evidence synthesis

BACKGROUND

Biofield therapies (such as Reiki, therapeutic touch, and healing touch) are complementary medicine modalities that remain controversial and are utilized by a significant number of patients, with little information regarding their efficacy.

PURPOSE

This systematic review examines 66 clinical studies with a variety of biofield therapies in different patient populations.

METHOD

We conducted a quality assessment as well as a best evidence synthesis approach to examine evidence for biofield therapies in relevant outcomes for different clinical populations.

RESULTS

Studies overall are of medium quality, and generally meet minimum standards for validity of inferences. Biofield therapies show strong evidence for reducing pain intensity in pain populations, and moderate evidence for reducing pain intensity hospitalized and cancer populations. There is moderate evidence for decreasing negative behavioral symptoms in dementia and moderate evidence for decreasing anxiety for hospitalized populations. There is equivocal evidence for biofield therapies' effects on fatigue and quality of life for cancer patients, as well as for comprehensive pain outcomes and affect in pain patients, and for decreasing anxiety in cardiovascular patients.

CONCLUSION

There is a need for further high-quality studies in this area. Implications and future research directions are discussed.

EFFECTS OF QI-THERAPY (EXTERNAL QIGONG) ON CARDIAC AUTONOMIC TONE: A RANDOMIZED PLACEBO CONTROLLED STUDY

Heart-rate variability (HRV) was compared in 40 subjects receiving external Qi-therapy (QT) or placebo control therapy, in a randomized placebo controlled design experiment. There were significant time, and group x time interactions in heart rate (HR), low frequency (LF), high frequency (HF), and LF/HF. These suggest that QT reduced the HR and increased HRV as indicated by a reduced LF/HF power ratio of HRV. These findings suggest that QT stabilizes the sympathovagal function more than placebo therapy.

IS THERE ANY DIFFERENCE IN THE EFFECTS OF QI THERAPY (EXTERNAL QIGONG) WITH AND WITHOUT TOUCHING? A PILOT STUDY

The aim of this study was to evaluate differences in the effects of Qi therapy without touching or with touching on anxiety, mood, neurohormones, and cellular immune function. Twenty-four healthy male subjects were randomly assigned to either QTN (n = 12) or QTT (n = 12). They received Qi therapy (external Qigong) without touching (QTN) or with touching (QTT). Nonparametric statistical tests revealed no significant differences between the effects of QTN and QTT (all p > .05). Separate Wilcox signed rank tests for each intervention revealed significant effects on anxiety, alertness, depression, fatigue, tension, cortisol levels, and NK cell cytotoxicity for both QTN and QTT, and on neutrophil function for QTN only. These findings suggest that there are few differences between the effects of QTN and QTT. However, the reproducibility of the findings should be tested with multiple sessions, and long-term follow-up tests.

External Qigong for Pain Conditions: A Systematic Review of Randomized Clinical Trials

The aim of this systematic review was to assess the clinical evidence of external qigong as a treatment option for pain conditions. Databases were searched up to January 2007. Randomized, clinical trials (RCTs) testing external qigong in patients with pain of any origin assessing clinical outcomes were considered. Trials using any type of control group were included. The selection of studies, data extraction, and validation were performed independently by at least 2 reviewers. One hundred forty-one potentially relevant studies were identified and 5 RCTs could be included. All RCTs of external qigong demonstrated greater pain reductions in the qigong groups compared with control groups. Meta-analysis of 2 RCTs showed a significant effect of external qigong compared with general care for treating chronic pain (Pain 100 mm VAS; weighted main differences, 36.3 mm; 95% CI, 22.8 to 49.8; P < .001; heterogeneity: chi(2) = 1.79, P = .18, I(2) = 44.0%, n = 80). The evidence from RCTs testing the effectiveness of external qigong for treating pain is encouraging. Further studies are warranted.

PERSPECTIVE

This review of clinical studies focused on the efficacy of qigong, an energy-healing intervention used to prevent and cure ailments. A meta-analysis shows that evidence for the effectiveness of external qigong is encouraging, though further studies are warranted.

Effects of Qi therapy (external Qigong) on symptoms of advanced cancer: a single case study

The aim of this study was to examine the effectiveness of Qi therapy (external Qigong) in the management of symptoms of advanced cancer in a man. We used a single case study design to evaluate the effectiveness of Qi therapy (external Qigong) in a 35-year-old man with advanced cancer (Stage IV) involving metastases in the stomach, lung and bone (Karnofsky performance scale: KPS, 40: requires special care and assistance, disabled). Treatment involved six days of pre-assessment, eight treatment sessions on alternate days over 16 days, and a two-week follow-up phase. A visual analogue scale (VAS) was used to assess the patient's self-reported symptoms of cancer over the intervention and follow-up periods. Following treatment, VAS scores' analysis revealed beneficial effects on pain, vomiting, dyspnoea, fatigue, anorexia, insomnia, daily activity and psychological calmness. These improvements were maintained over the two-week follow-up phase. After the first Qi therapy session, the patient discontinued medication and could sit by himself; after the fourth session, the patient was able to walk and use the toilet without assistance (improvement in KPS: 70: care for self, unable to perform normal activity or to do active work). Although limited by the single case study approach, our results support previous studies on this topic and provide reasons to conduct controlled clinical trials.

Efficacy of Qi-therapy (external Qigong) for elderly people with chronic pain

To test the efficacy of Qi-therapy (external Qigong) in improving symptoms of pain and mood states in elderly peoples with chronic pain. Forty-three elderly people with chronic pain were randomly assigned either to an intervention or a general care group. The intervention group was given four weeks of Qi-therapy whereas the control group was given standard care. Compared with the control group, Qi-therapy participants experienced improvements in positive mood and psychological variables over the four-week program. Compared with baseline values, pain and psychological benefits remained significantly improved after two weeks of follow-up. These findings suggest that Qi-therapy may help the elderly cope with pain and associated mood disturbances.

Effects of external qi-therapy on emotions, electroencephalograms, and plasma cortisol

The authors investigated the effect of external Qi-therapy (EQT) on changes in encephalograms (EEGs) and circulating cortisol concentrations. Ten college students participated in crossover sessions, receiving EQT or placebo treatment with their eyes open. Subjects reported improved emotions of satisfaction, relaxation, and calmness during EQT as compared to levels reported during placebo treatments. There were significant differences in the proportions of alpha and beta EEG waves between the two sessions, and the relative strengths of alpha waves were higher during EQT than during control sessions (p < .05). Plasma cortisol concentrations during EQT were significantly lower than during control sessions p < .05). Thus, Qi-therapy was more effective in inducing relaxation than placebo treatment.

Effects of Qi Therapy (External Qigong ) on Premenstrual Syndrome: A Randomized Placebo-Controlled Study

OBJECTIVES

To assess the effects of qi therapy on premenstrual symptoms in women with premenstrual syndrome (PMS).

DESIGN

A randomized placebo-controlled trial.

SUBJECTS

Thirty-six (36) college women with symptoms of PMS.

INTERVENTION

After 2 months of screening, subjects with PMS were randomized to receive real qi therapy (18 subjects) or placebo (18 subjects). The subjects were informed that they would receive one of two types of treatment. They did not know which treatment they received. Each intervention was performed eight times during the second and third cycles with subjects completing a PMS diary.

RESULTS

There were significant improvements in the symptoms of negative feeling, pain, water retention, and total PMS symptoms in subjects receiving qi therapy compared to placebo controls.

CONCLUSION

Qi therapy may be an effective complementary therapy for managing the symptoms of PMS.
