13 middle-aged (mean age=52.1 years), with 13 older (mean
age=74.8 years) and 13 young (mean age=23.3 years) healthy
adults participated in this study. We assessed following gait
parameters of the subjects during their level walking: 1)
temporal-spatial gait parameters: normalized gait velocity,
stride length, step length and their variability; 2) gait stability
parameters: acceleration root mean square (RMS) of COM and
its variability; and instantaneous COM-COP inclination angles.
