Fig. 3

Example of time-series data sample. (a) The force, moment, lateral position, and speed data of a subject in the HC group. (Male, 65 years, 170 cm, and 71 kg). (b) The force, moment, lateral position, and speed data of a subject in the PD group (Female, 70 years, 153 cm, and 63 kg). (c) Definition of the force and moment components measured by the two FT sensors. The arrow direction indicates positive direction. The arrow colors correspond to the colors of the force and moment graphs shown in (a) and (b).
