Data processing procedures to detect the instant of foot contact
Foot contacts and toe offs are annotated on the raw vertical acceleration data. Trough points are took from processed data (i.e. filtered, interpolated, and resampled data) to estimate the instant of foot contacts.

Test-retest reliability of spatiotemporal gait parameters according to the number of analyzed steps
Reliability is measured by the intraclass correlation coefficient type of (3,1), or ICC(3,1). The 3 cursor boxes in a graph represent the points to reach ICC = 0.75, plateau of ICC scores, and maximum ICC score, in that order from left to right.
