Experimental protocol. Participants stood on a force platform on the Neurocom® balance manager while the platform was translated in the anteroposterior direction. The platform was translated according to waveforms of different complexities. White noise represented a completely random movement, sine wave represented a completely periodic movement, and pink and brown noise represented different strengths of long-range correlation. Center of pressure was analyzed in the AP direction to determine if the complexity of standing posture would change based on the complexity of the input signal.
