Mood enhancement in health-promoting non-aerobic exercise: the role of non-specific mechanisms

Problems of scientific methodology related to placebo control in Qigong studies: A systematic review

INTRODUCTION

Qigong is widespread in the West and used for preventive care, stress-induced conditions, emotional and vegetative symptoms like migraine and hypertension, as well as for better coordination in the elderly and quality of life enhancement in severe disease such as cancer. Adequate controls for Qigong research are lacking, compromising the level of efficacy evidence. Adequate Qigong placebo control exercises should match clear and standardized criteria.

METHODS

Three computerized databases were assessed in January 2018 (Scopus, Web of Science and MEDLINE on PubMed) using the following keywords or their combinations: (Qigong OR Qi Gong OR Gong Qi OR Chi Kung OR Kung Chi OR Kiko OR Ki Gong OR Ki Kong) AND placebo. In addition, all reference lists were scanned for further relevant articles. Literature was examined for the effects of Qigong as compared to a control intervention.

RESULTS

110 articles were found, 78 of which were excluded after examining the title and abstract, and 16 because they were duplicates. Four more articles were found by searching in the bibliographies of published papers. A total of 20 studies were included in this systematic review. We found that, to the best of our knowledge, no criteria for placebo controls have been published in peer-reviewed journals so far.

CONCLUSION

Placebo controls should be developed by the usage of vegetative functional assessments such as heart rate variability, thermography, and electrophysiological measurements, thus excluding major vegetative effects of the exercise, as well as by the usage of psychometric tests and other quantitative evaluations.

Preference for different relaxation techniques by COPD patients: comparison between six techniques

Background

A review of the effectiveness of relaxation techniques for chronic obstructive pulmonary disease patients has shown inconsistent results, but studies have varied in terms of technique and outcome measures.

Aim

To determine patient preference for different relaxation techniques.

Methods

Chronic obstructive pulmonary disease patients were presented with six techniques via a DVD and asked to rate the techniques in terms of effectiveness, rank in order of likely use, and comment.

Results

Patients differed in the technique preferred and reason for that preference, but the most commonly preferred technique both for effectiveness and ease of use was “thinking of a nice place” followed by progressive relaxation and counting. Familiarity and ease of activity were commonly given reasons for preference.

Conclusion

Rather than providing patients with a single technique that they might find difficult to implement, these results suggest that it would be better to give a choice. “Thinking of a nice place” is a popular but under-investigated technique.

INDIVIDUALIZED YOGA FOR REDUCING DEPRESSION AND ANXIETY, AND IMPROVING WELL-BEING: A RANDOMIZED CONTROLLED TRIAL

BACKGROUND

Depression and anxiety are leading causes of disability worldwide. Current treatments are primarily pharmaceutical and psychological. Questions remain about effectiveness and suitability for different people. Previous research suggests potential benefits of yoga for reducing depression and anxiety. The aim of this study is to investigate the effects of an individualized yoga intervention.

METHODS

A sample of 101 people with symptoms of depression and/or anxiety participated in a randomized controlled trial comparing a 6-week yoga intervention with waitlist control. Yoga was additional to usual treatment. The control group was offered the yoga following the waitlist period. Measures included Depression Anxiety Stress Scale (DASS-21), Kessler Psychological Distress Scale (K10), Short-Form Health Survey (SF12), Scale of Positive and Negative Experience (SPANE), Flourishing Scale (FS), and Connor-Davidson Resilience Scale (CD-RISC2).

RESULTS

There were statistically significant differences between yoga and control groups on reduction of depression scores (-4.30; 95% CI: -7.70, -0.01; P = .01; ES -.44). Differences in reduced anxiety scores were not statistically significant (-1.91; 95% CI: -4.58, 0.76; P = .16). Statistically significant differences in favor of yoga were also found on total DASS (P = .03), K10, SF12 mental health, SPANE, FS, and resilience scores (P < .01 for each). Differences in stress and SF12 physical health scores were not statistically significant. Benefits were maintained at 6-week follow-up.

CONCLUSION

Yoga plus regular care was effective in reducing symptoms of depression compared with regular care alone. Further investigation is warranted regarding potential benefits in anxiety. Individualized yoga may be particularly beneficial in mental health care in the broader community.

Why practice yoga? Practitioners’ motivations for adopting and maintaining yoga practice

We examined motives for adopting and maintaining yoga practice in a national survey of yoga practitioners (360 yoga students, 156 yoga teachers). Both students and teachers adopted yoga practice primarily for exercise and stress relief, but reported many other reasons, including flexibility, getting into shape, and depression/anxiety relief. Over 62 percent of students and 85 percent of teachers reported having changed their primary reason for practicing or discovering other reasons; for both, the top changed primary reason was spirituality. Findings suggest that most initiate yoga practice for exercise and stress relief, but for many, spirituality becomes their primary reason for maintaining practice.

The Functional Well-Being Scale: a measure of functioning loss due to well-being-related barriers

The objective of this study was to develop the Pro-Change Functional Well-Being Scale, a measure that provides an informative evaluation of general functioning loss due to well-being-related barriers. Exploratory and confirmatory analyses on data from 642 individuals supported a one-factor solution with good model fit. A strong positive correlation existed between the Pro-Change Functional Well-Being Scale and Well-Being Assessment for Productivity. Initial construct validity was demonstrated by predictable relationships between functioning loss and other measures of health and well-being. This initial psychometric evidence suggests that the Pro-Change Functional Well-Being Scale is a reliable and valid assessment of functioning loss due to common well-being-related barriers.
