Cross-correlations of center of mass and center of pressure displacements reveal multiple balance strategies in response to sinusoidal platform perturbations

► Center-of-mass (COM) and center-of-pressure (COP) displacements relevant to balance. ► Participant kinematics were similar for sagittal sinusoidal platform perturbations. ► However, two different COM-COP displacement cross-correlation patterns emerged. ► Platform power application indicated a different balance strategy for each pattern. ► Combined kinetic and kinematic data are critical for complete strategy analysis.
