  1. Variability analysis includes: inter-day variation, inter-trial variation, inter-tester variation. Mean and SD are obtained from a single subject among five examiners over the mean of three repetitions (inter-session variability), from a single subject and the same clinician during the same day over the mean of three repetitions (inter-trial variability), from a single subject and the same clinician during two different sessions separated by several weeks over the mean of three repetitions (inter-day variability). In [22] one subject was examined by five different testers and repeatedly by the same tester for five sessions. In [19] sixteen test sessions were completed with two testers assessing each of two healthy subjects independently over four days separated by a minimum of one week. In [21] fifteen healthy children were tested on three separate occasions. Visits were spaced between 2 weeks and 6 months apart, three representative strides from three separate trials were used for analysis from each session.
