From: The validity of spatiotemporal gait analysis using dual laser range sensors: a cross-sectional study
Typical time-course data of each leg position and acceleration calculated from laser range sensors: a) Example of each leg position during walking where the x-axis indicates time (s) and the y-axis indicates the distance from the proximal side laser to the participant’s shin (m). b) Example of each leg acceleration derived from position data. The y-axis indicates the acceleration values (m/s2). Foot contact (FC) time was defined as the minimum of the smoothed time series acceleration values, and foot off (FO) time was defined as the maximum of the smoothed time series acceleration values. The black and gray solid line indicate the data of each leg which are smoothed by the moving average. The black solid line indicates left leg and the gray solid line indicates right leg
