ABSTRACT
BACKGROUND: The goal was to investigate the effects of Brain Wave Vibration (BWV), a meditation practised in a class involving rhythmic movements of the head, neck and body practised with related yoga-style exercises, and to isolate the rhythmic effects. METHODS: A randomised controlled trial was conducted with assessments pre- and post-trial and immediately before and after each session. Thirty-one healthy adults were assessed for mood, sleep, mindfulness, health and well-being, and pre- and post-class activation-deactivation. Participants were randomly assigned to either BWV in toto or a control group having similar yoga exercises without the rhythmic components. Participants completed eight to twelve 75-min classes of BWV or control training over 8-12 weeks. To control for expectation participants were told only that the aim was to compare two subtly different styles of Korean yoga. RESULTS: The BWV group had comparatively greater improvements in sleep duration and efficiency, although they had higher baseline inefficiency, and post-trial they had better global sleep and well-being and fewer illness symptoms, and better tiredness and energy post-class. Both groups benefitted in mood, mindfulness and vitality post-trial with improved tension and calmness post-class. CONCLUSIONS: The participants of both interventions had better mood and well-being on the whole following the trial and were more relaxed immediately after a class. However, BWV training was unique in its benefits to sleep, health, well-being, energy and tiredness, warranting further research.
