Amputés et montée d'escaliers -
OBJECTIVE: To investigate the construct validity and test-retest reliability of
the Climbing Stairs Questionnaire, a patient-reported measure of activity
limitations in climbing stairs, in lower-limb amputees.
DESIGN: A cross-sectional
study. SETTING: Outpatient department of a rehabilitation center. PARTICIPANTS:
Lower-limb amputees (N=172; mean +/- SD age, 65+/-12y; 71% men; 82% vascular
cause) participated in the study; 33 participated in the reliability study.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): Construct validity was
investigated by testing 10 hypotheses: limitations in climbing stairs according
to the Climbing Stairs Questionnaire will be greater in lower-limb amputees who:
(1) are older, (2) have a vascular cause of amputation, (3) have a bilateral
amputation, (4) have a higher level of amputation, (5) have more comorbid
conditions, (6) had their rehabilitation treatment in a nursing home, and (7)
climb fewer flights of stairs. Furthermore, limitations in climbing stairs will
be related positively to activity limitations according to: (8) the Locomotor
Capabilities Index, (9) the Questionnaire Rising and Sitting down, and (10) the
Walking Questionnaire. Construct validity was quantified by using the
Mann-Whitney U test, Kruskal-Wallis test, and Spearman correlation coefficient.
Test-retest reliability was assessed with a 3-week interval and quantified using
the intraclass correlation coefficient (ICC). RESULTS: Construct validity (8 of
10 null hypotheses not rejected) and test-retest reliability were good (ICC=.79;
95% confidence interval, .57-.90). CONCLUSION:
The Climbing Stairs Questionnaire
has good construct validity and test-retest reliability in lower-limb amputees.
