Time 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. Trial_2 − 3 is constituted of repetitions 2 and 3 while Trial_4 − 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 Trial_2 − 3 are the mean of the gait speed metrics from repetitions 2 and 3) or by the median of all five repetitions.
