ABILOCO: A Rasch-Built 13-Item Questionnaire to Assess Locomotion Ability in Stroke Patients

(A) The distribution of patient’s perceived locomotion ability as assessed by ABILOCO. (B) The items by decreasing difficulty are shown from top to bottom; this figure shows the patient’s expected responses to each item as a function of the underlying measure of locomotion ability. (C) The ogival relationship between the ABILOCO total raw score and the score expressed in logits on the linear scale.

The relationships between the ABILOCO and (A) the FWC, (B) FIM walking ability (item 12), (C) the FAC, and (D) walking speed as measured with the 10MWT. Boxplots (panels A, B, C) show the patient distributions in a given category; the box indicates the 25% and 75% limits, and the vertical line inside the box indicates the median. The vertical bars indicate the 10% and 90% limits, and the solid dots indicate the 5% and 95% outliers. The number of patients (n) in each category is indicated. The ρ values report the results of the Spearman correlation test. In panel D, each point shows the results obtained for 1 patient. The r value reports the results of the Pearson correlation test.
