Experimental setup. A: Participants stood on the force platform with arms crossed over the chest and swayed mainly about ankle joints in the anterior-posterior direction. The platform coordinate system also is shown. A safety harness always was worn by participants (not drawn). B: Visual feedback of both COPAP and COPML. Participants shifted their center of pressure between targets shown on the screen as two horizontal lines (6 cm peak-to-peak and symmetrical with respect to the initial standing position).
