Reproducibility of the ABILOCO questionnaire and comparison between self-reported and observed locomotion ability in adult patients with stroke.

Abstract

To test the reproducibility of the ABILOCO questionnaire. To validate the patient self-reporting method and the third-party assessment of the stroke patients' locomotion ability by a treating physical therapist. Prospective study. University hospital. Adult stroke patients (N=28; 59+/-13y). The time since stroke ranged from 3 to 253 weeks. Not applicable. The ABILOCO questionnaire. The results of patient self-assessment and the results of the third-party assessments by the physiotherapists at a 2-week interval were highly correlated (intraclass correlation coefficient [ICC]=.77 and ICC=.89, respectively). The results of the patient self-assessment and the third-party assessment by the physical therapist were both well correlated to assessment by an independent medical examiner who observed the patient during the 13 ABILOCO activities (ICC=.69 and ICC=.87, respectively). The use of ABILOCO as a self-reporting questionnaire is a valid and reproducible method for assessing locomotion ability in patients with stroke in daily clinical practice and research.
