Background The ABILOCO is a self‐reported questionnaire, specific for individuals with stroke, for the assessment of ability of locomotion. The ABILOCO has been investigated using the Rasch model and has shown satisfactory measurement properties. However, its test‐retest reliability has not been investigated. Objective To investigate the test‐retest reliability, that is, agreement, systematic and random variability of the ABILOCO Questionnaire in individuals with chronic stroke. Design A test‐retest reliability study. Setting Research laboratory. Participants Thirty‐one individuals (21 men and 10 women; mean age, 60 years), who had poststroke hemiparesis. Intervention Not applicable. Main Outcome Measurement The ABILOCO was applied twice, on two occasions, 5 to 7 days apart. Test‐retest reliability was investigated, as follows: agreement by the calculation of intraclass correlation coefficients (ICCs); systematic variability by the change in the mean; random variability by the standard error of measurement (SEM) and smallest real difference (SRD). Results Two outliers were identified in the sample. The ICC values for the whole sample were 0.76 (CI 95% 0.56 to 0.88), whereas the SEM (SEM%) and SRD (SRD%) were 0.55 (21%) and 1.52 (58%), respectively. Conclusion The ABILOCO showed to be reliable to be applied within clinical and research contexts for the assessment of changes in locomotion ability of a group of individuals with chronic stroke. However, it appears to be less suitable to detect changes at individual levels. Level of Evidence III.
