Inter-foot coordination dynamics of quiet standing postures

Z Wang, KM Newell - Neuroscience & Biobehavioral Reviews, 2014 - Elsevier
It has long been held that the net center of pressure (COP NET) is the controlling variable to
human stance that indirectly represents postural sway. The formation of the COP NET …

The effects of foot position and orientation on inter-and intra-foot coordination in standing postures: a frequency domain PCA analysis

Z Wang, PMC Molenaar, KM Newell - Experimental brain research, 2013 - Springer
