Feasibility and relative and absolute inter-tester reliability for the measurements of physical performance.

HGS: isometric handgrip strength (kg), CS: 30-s chair stand test (repetitions), GS: gait speed (Exp β), CAS: Cumulated Ambulation Score (points), CSG: Chair stand test, categorized as the ability to do the following: rise without using the armrest with arms folded across the chest, rise using the armrest, or inability to rise independently from the chair, β: mean differences between morning and afternoon session using a mixed effect model, ICC1.1: intraclass correlation coefficient model 1.1, LL95: Lover 95% confidence limit, SEM: standard error of measurement, SEM%: standard error of measurement expressed as a percentage of the mean, SRD95: Smallest real difference at the 95% confidence level, SRD%: smallest real difference as a percentage of the means. aSEM and SRD were not calculated as GS is log-transformed. bThe calculation of the weighted kappa was based on N = 51, as 51 patients participated in the repeated testing Feasibility and relative and absolute inter-tester reliability for the measurements of physical performance.
