Abstract
We investigated quiet stance of newly standing toddlers every three months (trimesters) of their second year of life. Their anteroposterior center-of-pressure (CoPx) velocity and centroidal frequency (CFREQ: 2.36 ± 0.10 to 1.50 ± 0.11 Hz) decreased over time. Besides, mean pressures revealed a potential role-sharing of foot regions in learning and control aspects of standing, with hindfoot carrying the highest (23.89 ± 6.47 kPa) pressure while forefoot the lowest (10.26 ± 2.51 kPa). The highest CFREQ of pressure signal was at midfoot. Through regional CoPx, forefoot has manifested the highest CFREQ (2.10 ± 0.40 Hz) and 90% power frequency (90%PF), whereas hindfoot presented the lowest (CFREQ: 1.80 ± 0.33 Hz). CFREQ and 90%PF of pressure and regional CoPx significantly decreased throughout the trimesters.
