Fig. 1From: Minimal detectable change of gait and balance measures in older neurological patients: estimating the standard error of the measurement from before-after rehabilitation data thanks to the linear mixed-effects modelsTime course of the mobility assessment. Gait and balance have been assessed in two assessment sessions, T0 and T1 (dark grey boxes), the first at the beginning and the second at the end of the participants’ inpatient rehabilitation stay (light grey box). Five repetitions of the 10 m walking and TUG tests have been collected in each session. Trial2 − 3 is constituted of repetitions 2 and 3 while Trial4 − 5 by repetitions 4 and 5. Measures of the variable of interest from a single test repetition are referred to here as “metric” (e.g. the five repetitions of, say, the 10 m walking test return five metrics of gait speed). Participants’ measures are given by the mean of two metrics (e.g. participants’ gait speed measures from Trial2 − 3 are the mean of the gait speed metrics from repetitions 2 and 3) or by the median of all five repetitions.
