Abstract

Health Qigong is a common technique of Traditional Chinese Medicine applied to strengthen mental and physical health. Several studies report increases in EEG theta and alpha activity after meditative Qigong techniques indicating a relaxed state of mind. To date, little is known on the effects of dynamic Health Qigong techniques that comprise bodily movements on brain activity. In the current study, we compared effects of two dynamic Health Qigong techniques on EEG brain activity. Subjects performed the techniques Wu Qin Xi (five animals play) and Liu Zi Jue (six healing sounds) in a within-subjects design. Eyes-open and eyes-closed resting EEG was recorded before and immediately after each 15-min practice block. Additionally, the Profile of Mood States (POMS) questionnaire was administered at pretest, and after each 15-min practice block. Results show a decrease in alpha activity after 15 min, followed by an increase after 30 min in the Health Qigong technique Liu Zi Jue. Theta activity was decreased after 15 min, followed by an increase after 30 min in the technique Wu Qin Xi. Results of the POMS indicated an increased vigor-activity level with decreased fatigue and tension-anxiety levels in both techniques after 30 min of practice. Our results demonstrate different temporal dynamics in EEG theta and alpha activity for the Health Qigong techniques Wu Qin Xi and Liu Zi Jue. We hypothesize that the found brain activation patterns result from different attentional focusing styles and breathing techniques performed during the investigated Health Qigong techniques.

Highlights

Health Qigong is a technique of Traditional Chinese Medicine (TCM) applied commonly to strengthen physical and mental health
Most studies report an increase in EEG theta and alpha activity during and after static Qigong meditation
We investigated effects of the dynamic Qigong techniques Wu Qin Xi and Liu Zi Jue with emphasis on the temporal course of brain activation at training durations of 15 and 30 min, respectively

Summary

Introduction

Health Qigong is a technique of Traditional Chinese Medicine (TCM) applied commonly to strengthen physical and mental health. In several studies on meditative Qigong practice beneficial effects on health have been observed (for an overview see Ng and Tsang, 2009). Positive effects of Qigong practice on mental health were shown in anxiety disorders (Lee et al, 2004; Abbott and Lavretsky, 2013; Chan et al, 2013), posttraumatic stress disorders (Grodin et al, 2008; Kim et al, 2013), major depression A stress alleviating effect was shown in healthy practitioners (Posadzki et al, 2010; Terjestam et al, 2010; Glei et al, 2012; Sousa et al, 2012; Hwang et al, 2013; Shim, 2014; Wang et al, 2014)
