Eeg Activation Induced by Facilitating Position

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.
