Centre of Pressure (COP) metrics and cross-correlation analysis between COP and electromyogram (EMG) obtained from the two model structures in comparison with experimental data reported in the literature.

Model 1 is the postural control model without reciprocal inhibition, whereas Model 2 is the complete postural control model (see Methods for details concerning model structures). Data are expressed as Mean Standard Deviation. is defined as the frequency at which 50% of the total power of the COP is confined (see Data Analysis). Values of were measured as the peak values of the cross-correlation functions between COP and the EMGs of the Triceps Surae (TS) muscles (i.e., SO, MG, and LG). Data from [9], [42], [43] were obtained from healthy young subjects standing on a stable surface without visual feedback, while [3] provided data from vestibular loss patients standing on a stable surface without visual feedback.Centre of Pressure (COP) metrics and cross-correlation analysis between COP and electromyogram (EMG) obtained from the two model structures in comparison with experimental data reported in the literature.
