Enhancing Subjective Well-Being Through Qigong: A Randomized Controlled Trial in Older Adults in Hong Kong With Chronic Physical Illness.

Context: Eight-section Brocades, a qigong protocol, has been shown to reduce depressive symptoms in older adults with chronic physical illness, but its positive effects on quality of life, such as subjective well-being, aren't known. Objective: This study intended to evaluate the efficacy of qigong for increasing subjective well-being in older adults with chronic physical illness. Design: A randomized controlled trial was conducted. Setting: A governmental family clinic in Hong Kong. Participants: Participants were 47 older adults, 19 males and 28 females, with chronic physical illness. Intervention: Participants were randomly assigned to an Eight-section Brocades group (n = 25) or a cognitive training group (n = 22). The groups received 12 weeks of the Eight-section Brocades intervention or of cognitive training, respectively. Outcome Measures: The primary outcome-subjective well-being-and the secondary outcomes-functional independence, sleep quality, mobility, and hand grip strength-were assessed at baseline, postintervention, and at a one-month follow-up. Results: No significant between-group differences were observed in improvements in subjective well-being or any of the secondary outcomes. Significant improvements in subjective sleep quality and decreases in daytime dysfunction over time were reported by participants in both groups. Conclusions: The findings didn't support 12 weeks of Eight-section Brocades qigong as an effective treatment to enhance the subjective well-being of older adults with chronic physical illness. These null findings may be due to the possibilities that: (1) the treatment may have minimal effects on positive psychology outcomes; (2) the primary outcome measure showed possible ceiling effects for the groups; (3) the current study used an active control condition that may have had more benefits than the control conditions used in previous studies; (4) the current study may have been underpowered; (5) more than 12 weeks (24 sessions) of qigong may be required to impact well-being; or (6) some combination of these factors may have affected the results.

Qigong for the treatment of depressive symptoms: Preliminary evidence of neurobiological mechanisms.

OBJECTIVES: Qigong has been shown to effectively reduce depressive symptoms in older adults with chronic physical illness. Here, we sought to evaluate the effects of qigong on serotonin, cortisol, and Brain-derived Neurotropic Factors (BDNF) levels and test their roles as potential mediators of the effects of qigong on depressive symptoms. METHODS: Thirty older adults with chronic physical illness participated in a randomized clinical trial. They were randomly assigned to a qigong group (n = 14) or a control group for cognitive training of executive function and memory (n = 16). The participants provided blood and saliva samples at baseline and post-intervention. Levels of cortisol were measured from the salvia samples, and serotonin and BDNF were measured from the blood samples. RESULTS: Consistent with the study findings presented in the primary outcome paper, a significant Group × Time interaction effect emerged on depressive symptoms, explained by greater reductions in the qigong group than the control group. Qigong participants had significantly larger increases in serotonin and BDNF, and decreases in cortisol levels, compared with control group participants. Moreover, treatment-related changes in cortisol levels (but not serotonin or BDNF) fully mediated the beneficial effects of qigong on depressive symptoms. CONCLUSION: The findings provide preliminary evidence that treatment-related changes in cortisol may mediate the benefits of qigong on depressive symptoms. Given the limitation of small sample size of the present study, future studies with larger sample sizes and more extended follow-up assessment are warranted to determine the reliability of these findings.

Effects of tai chi for patients with knee osteoarthritis: a systematic review.

[Purpose] The aim of the present study was to seek evidence for the effectiveness of Tai Chi for patients with knee osteoarthritis (KOA). [Subjects and Methods] Systematic searches were conducted of the China Journals Full-text Database, Pubmed, Medline, Science Direct-Online Journals and CINAHL for studies published between 2000 and 2012. Studies were evaluated based on following inclusion criteria: 1) design: randomized control, clinical trial; 2) subjects: patients with a knee osteoarthritis diagnosis; 3) intervention: exercise involving Tai Chi; 4) studies published in English or Chinese. [Results] Six randomized control studies involving Tai Chi and knee osteoarthritis were found. [Conclusion] Tai Chi was an effective way of relieving pain and improving physical function. Further randomized controlled trials with large sample sizes and long training period are needed to compare groups who perform Tai Chi training with other groups who undergo other forms of physical exercise in order to confirm the efficacy of Tai Chi.

[Clinical efficacy of shallow-needle therapy combined with estazolam on insomnia of liver stagnation transforming into fire pattern: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of shallow-needle therapy combined with estazolam on insomnia differentiated as liver stagnation transforming into fire and its effect on adrenocorticotropic hormone (ACTH) and cortisol (CORT), so as to explore the mechanism of this combined treatment. METHODS: A total of 119 patients with insomnia of liver stagnation transforming into fire pattern were randomly divided into shallow-needle therapy group (n=40), medication group (n=39), and shallow-needle therapy combined with medication group (combined therapy group,n=40). In the shallow-needle therapy group, the patients were treated with finger pressure and operation with shallow stimulating at Zhenjing (Dong's extra point, sedative point) and Taichong (LR3). In the medication group, the patients were administered with estazolam (1 mg) orally. In the combined therapy group, both shallow-needle therapy and medication were administered. The treatment was given once daily in each group, 10 days as one session of treatment and 2 sessions were required. Before and after the treatment, Pittsburgh sleep quality index scale (PSQI) and Self-rating anxiety scale (SAS) were used to assess sleep and anxiety status. ELISA was used to detect the contents of ACTH and CORT in plasma. The clinical efficacy was evaluated in each group. RESULTS: In within-group comparison, PSQI scores, SAS scores and the concentrations of ACTH and CORT in plasma were all decreased (P<0.05) after treatment for the patients of three groups. After treatment, the total PSQI score, the score for sleep latency, sleep duration and daytime dysfunction, as well as SAS score in the combined therapy group were all lower than those of the shallow-needle therapy group (P<0.05); the total PSQI score, the score for sleep duration and sleep efficiency, as well as SAS score were lower when compared with the medication group (P<0.05). The total effective rates were 87.50% (35/40), 82.05% (32/39) and 95.00% (38/40) in the shallow-needle therapy group, the medication group and the combined therapy group, respectively. The total effective rate in the combined therapy group was higher than those of the shallow-needle therapy group and the medication group separately (P<0.05). CONCLUSION: Shallow-needle therapy combined with estazolam is effective on insomnia of liver stagnation transforming into fire pattern, and its underlying effect mechanism is related to the reduction of plasma ACTH and CORT levels.

The Safety of Baduanjin Exercise: A Systematic Review.

OBJECTIVES: Baduanjin exercise is a form of Qigong exercise therapy that has become increasingly popular worldwide. The aims of the current systematic review were to summarize reported adverse events potentially associated with Baduanjin exercise based on currently available literature and to evaluate the quality of the methods used to monitor adverse events in the trials assessed. METHODS: The English databases PubMed, Cochrane library, and EMbase were searched from inception to October 2020 using the keywords "Baduanjin" or "eight session brocade." Only studies that included Baduanjin exercise therapy were included. RESULTS: Forty-seven trials with a total of 3877 participants were included in this systematic review. Twenty-two studies reported protocols for monitoring adverse events, and two studies reported the occurrence of adverse events during training. The adverse events reported included palpitation, giddiness, knee pain, backache, fatigue, nervousness, dizziness, shoulder pain, chest tightness, shortness of breath, and muscle ache. CONCLUSIONS: Only two studies reported adverse events that were potentially caused by Baduanjin exercise. Adverse events related to Baduanjin exercise in patients with chronic fatigue syndrome may include muscle ache, palpitation, giddiness, knee pain, backache, fatigue, nervousness, dizziness, shoulder pain, chest tightness, and shortness of breath. Further studies conducted in accordance with the Consolidated Standards of Reporting Trials statement guideline incorporating monitoring of adverse events are recommended. Additional clinical trials in which Baduanjin exercise is used as a main intervention are needed, and further meta-analysis may be required to assess its safety and reach more informed conclusions in this regard in the future.

The Neurophysiological and Psychological Mechanisms of Qigong as a Treatment for Depression: A Systematic Review and Meta-Analysis.

Objective: An increasing number of studies have shown the anti-depressive effect of qigong. However, its underlying mechanism remains poorly understood. This study aims to systematically review and meta-analyze existing literature on the mechanism of qigong in reducing depression. Method: The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials of qigong were searched from PsycINFO, PubMed, Embase, ScienceDirect, and Academic Search Premier from inception to December 2018. Studies which involved depression and any neurophysiological or psychological mechanisms as outcomes were included. Publication bias was tested before conducting meta-analysis. Two independent raters were involved for the entire review process. Results: A total of nine studies were identified which covered both neurophysiological and psychological mechanisms. Among these selected studies, seven were involved in meta-analysis, which suggested that qigong was effective in alleviating depression (standardized mean difference, SMD = -0.27, p < 0.05, I 2 = 27%). A significant effect was also found for diastolic blood pressure (SMD = -1.64, p < 0.05, I 2 = 31%). However, no significant effect was found for cortisol level and systolic blood pressure. Conclusions: This review shows that qigong is effective in reducing depression through activating the parasympathetic nervous system. Future studies with higher quality of research methodology with less selection and attrition bias should be conducted to unravel the possible anti-depressive effect of qigong.

An East Meets West Approach to the Understanding of Emotion Dysregulation in Depression: From Perspective to Scientific Evidence.

Depression, an emotion regulation disorder, is a prevalent mental illness in the world. Meanwhile, traditional Chinese medicine (TCM) has been increasingly regarded as a promising and effective alternative therapy approach for patients with depression. Despite many years of research on depression, the current understanding of the pathological mechanism of depression based on TCM theories is still in its infancy. Due to the lack of scientific evidence in the past, TCM is not fully recognized by researchers around the world. This review firstly summarizes the pathogenesis and etiology of depression in terms of both Eastern and Western medical systems. Secondly, it adopts an integrated Eastern and Western approach to propose some plausible neurophysiological pathways linking the liver, spleen, and heart functions explicated in TCM theory. The aim of this theoretical review is to bridge the knowledge gap between Eastern and Western medicine, which may better explain the pathology of depression.

The Effects of Baduanjin Qigong on Postural Stability, Proprioception, and Symptoms of Patients With Knee Osteoarthritis: A Randomized Controlled Trial.

Background: Knee osteoarthritis is a common disease affecting a large number of old individuals worldwide. This study aimed to explore the effects of Baduanjin Qigong in patients with knee osteoarthritis. Methods: Fifty participants with knee osteoarthritis were randomly assigned to either an experimental group (n = 25) or a control group (n = 25). Participants in the experimental group received Baduanjin Qigong training for 12 weeks, with three sessions per week lasting 40 min per session. Participants in the control group did not receive any additional physical training. All of participants completed outcome (proprioception, postural stability, and functional ability) assessments at three time points (baseline, Week 8, 12). Results: Proprioception and Western Ontario and McMaster Universities Osteoarthritis Index function were statistically improved at eighth and 12th week of the intervention in the Baduanjin Qigong group (p < 0.05), while the control group did not have any significant changes. For postural stability at the anterior-posterior direction with eyes closed, Baduanjin Qigong group showed significant improvement compared to controls after the 12 weeks of intervention (p < 0.05). Conclusions: Regular Baduanjin Qigong practice helped the improvement of knee joint proprioception and postural stability, and reduction of pain, stiffness, and functional impairments of old adults with knee osteoarthritis. Well-designed randomized controlled trials with long-term assessment are needed. The trial was registered in Chinese Clinical Trial Registry (ChiCTR-IOR-16010042).

[Clinical characteristics of 100 vestibular migraine cases].

OBJECTIVE: To analyze the characteristics of vestibular migraine (VM), in order to understand the auditory and vestibular function. METHOD: One hundred cases of confirmed or suspected VM patients were observed. Routine examination including pure tone test, vestibular dual temperature test and vestibular evoked myogenic potential(VEMP) and video head impulse test(v-HIT) Were conducted. RESULT: The incidence of male and female was about 1.00 : 2. 57. The average age of onset was 47 years, of which the youngest was 19 years old, and the oldest was 74 years old. Ninty-three cases of patients presented with vestibular sensitive performance, including photophobia, phonophobia,or motion sensitive. Fourty-two patients had migraine at the onset of the disease. Thirty-four patients had cochiear symptoms, including tinnitus, ear fullness, or epicophosis. In seventeen cases of fatigue, tension or poor sleep can cause vertigo. Nine patients had low blood pressure, 7 patients presented with hypertension. Two cases of vertigo were closely related to the change of position, and 1 case had visual aura. In the experiment, 94 patients had undergone VEMP test,with 44 cases of abnormal VEMP value. Seventy-nine patients had been examined v-HIT,of whom 2 patients were abnormal (both of which were reduced). Pure tone audiometry was abnormal in 35 cases. Five cases of patients showed abnormal vestibular-double temperature test. CONCLUSION: Vestibular migraine is more prone to female, with young middle age, and can be accompanied by cochlear symptoms. Vestibular function tests (low frequency and high frequency) are normal.
