摘要：

A method is described for computing the centre of mass (COM) from empirical estimates of the centre of pressure (COP) obtained by means of a force platform, The method is based on a biomechanical model of sway movements in quiet standing, according to which the horizontal acceleration of the COM is approximately proportional to the COM-COP difference. The equations are solved by approximating the solution with best fitting spline functions. The implications for movement control are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
