Peer-Reviewed Research Review: EEG Brain Activity in Dynamic Health Qigong Training
Same Effects for Mental Practice and Physical Training?
The study titled "EEG Brain Activity in Dynamic Health Qigong Training: Same Effects for Mental Practice and Physical Training?" by Diana Henz and Wolfgang I. Schöllhorn investigates the neurophysiological effects of physical versus mental practice of Qigong on brain activity using electroencephalogram (EEG) measurements. The primary aim was to determine if mental practice can elicit similar EEG changes as physical training in dynamic Qigong exercises.
Background
Qigong, an integral part of Traditional Chinese Medicine (TCM), combines physical movements, breathing techniques, and meditation to promote physical and mental health. The specific form studied, Wu Qin Xi (the Five Animal Frolics), involves a series of movements mimicking the actions of a tiger, deer, bear, monkey, and bird. Prior research has demonstrated various health benefits of Qigong, including improvements in cardiovascular health, mental health, and stress reduction. However, studies examining the neurophysiological effects, particularly those involving EEG, are less common for dynamic forms of Qigong compared to static meditative practices.
Methodology
The study recruited 25 participants with prior Qigong experience. Each participant underwent three different conditions: physical practice of Wu Qin Xi, mental practice of the same, and a control condition where they watched a video of the exercises. EEG recordings were taken before and after each condition, under both eyes-open and eyes-closed states. The EEG data were analyzed for power changes in theta, alpha-1, alpha-2, beta, and gamma frequency bands across different brain regions.
Results
The study found significant increases in alpha power in posterior regions and theta power in central areas after both physical and mental Qigong practice, indicating a state of relaxation and focused attention. Specifically, physical and mental practices led to increased alpha-1 and alpha-2 power under eyes-open conditions, with mental practice showing a unique decrease in theta power under eyes-closed conditions.
Key findings include:
Alpha Power Increase: Both physical and mental practices increased alpha power, suggesting both forms of practice can induce a relaxed mental state.
Theta Power Modulation: Mental practice resulted in increased theta power in central areas for eyes-open conditions, whereas theta power decreased in fronto-central areas for eyes-closed conditions, suggesting differences in attentional processes between the two states.
Physical vs. Mental Practice: No significant differences in theta and alpha power were observed between physical and mental practices, supporting the hypothesis that mental practice can effectively mimic the neurophysiological effects of physical Qigong training.
Discussion
The results align with previous findings on static Qigong and meditation, where increased alpha activity is associated with relaxation and theta activity with attentional processes. The study's novel contribution lies in demonstrating that mental practice alone can achieve similar EEG changes as physical practice, highlighting its potential for individuals who cannot perform physical exercises due to space constraints, physical disabilities, or other limitations.
The study suggests that mental practice involves high degrees of internalized attention, evidenced by the observed theta activity patterns. This has practical implications for designing Qigong interventions for various populations, including the elderly, patients with physical impairments, and athletes during injury rehabilitation.
Implications for Future Research
Future studies could further explore the long-term effects of mental Qigong practice on neuroplasticity and functional outcomes in clinical populations. Investigating the role of expertise level in mental practice and its impact on EEG activity could provide deeper insights into the cognitive and neurophysiological processes underlying Qigong training.
Conclusion
Henz and Schöllhorn's study underscores the efficacy of mental practice in replicating the neurophysiological benefits of physical Qigong training. This finding expands the applicability of Qigong as a therapeutic intervention, offering a viable alternative for those unable to engage in physical exercise. The study bridges a gap in Qigong research by providing evidence of the comparable effects of mental and physical practices on brain activity, paving the way for broader implementation and further scientific exploration.
