Figure 4

The grand average spectra from the frequency analysis of center of pressure sway path velocity (distance/time) presented in ~0.5Hz frequency bins for 29 controls (open squares, gray) and 15 alcoholics (filled squares, black). The grand average spectra for the anterior-posterior plane are in the top panel of four figures (eyes closed/feet together; eyes closed/feet apart; eyes open/feet together; eyes open/feet apart). The grand average spectra for the medial-lateral plane are in the bottom panel. Note the peak in power in the 5-7 Hz frequency band in the alcoholic relative to the control women.
