Effects of yoga on brain wave coherence in executives.
Aim of this study was to assess the effect of Self Management of Excessive Tension (SMET), a yoga based stress management program on brain wave coherence. Brain wave recordings were taken with Brain Master 2 Channel EEG (version-2.0). The subjects for the study were 72 corporate executives, 48.75 +/- 3.86 years of mean age referred from Oil and Natural Gas Corporation Limited. EEG data was recorded on the first and sixth day of 5 days SMET program. A complete statistical and spectral analysis showed 19.31% increase (p=0.03) in delta, 5.04% increase (p=0.65) in theta, 15.40% increase (p=0.09) in alpha, 1.67% decrease (p=0.54) in beta and 18.68% increase (p=0.07) in gamma wave coherence between pre and post intervention measurements. Taken together, these results suggest that participation in a SMET program was associated with improvement in emotional stability and may have implications for 'Executive Efficiency'. Because before and after designs limit inferences about intervention effects, further research is warranted to explore the effects of SMET program for stress management using a larger, randomized controlled trial.
