Intra-foot coordination between center of pressure (COP) of the ball and heel of
the foot in single leg standing and inter-foot coordination of the right and left
foot during bipedal stance was examined as a function of postural stance (two
legs, one leg, and toe postures), footwear (barefoot, different area based high
heel shoes) and postural training (ballet group and regular exercising group).
Young adult females performed three 20s trials in each postural condition. In
general, the traditional variability measures of COPnet motion increased under
the less stable postural support conditions and ballet dancers had better balance
in single leg standing. Regularity analysis revealed a negative relation between
the variability of foot coupling (both intra- and inter-foot) and the standard
deviation of COPnet that was mediated by the interaction of shoe support and
postural stance. The findings show that shoe support and postural stance modulate
collective postural motion (COPnet) through the adaptability of the coupling of
foot dynamics.
