The effect of facilitating position of the lower extremity on EEG states was examined through topographical analysis of spectral power for each major frequency band in 8 healthy male subjects. Compared to neutral position, facilitating position of the left or right lower extremity produced significant changes in spectral power, especially in terms of non-specific increase at alpha band (8-12.8 Hz). These results provide further evidence of arousal shift induced by facilitating position, and suggest that EEG topography is a suitable indicator of monitoring the effect of facilitating position. facilitating position; EEG topography; alpha rhythm; arousal.
