OBJECTIVES: To test the strength of association between 2 clinic-based measures
of walking ability, the 1-minute walk test (1MWT) and the six-minute walk test
(6MWT), and the parental report of usual walking performance, measured by the
ABILOCO-Kids logit score, in children with cerebral palsy (CP). DESIGN:
Observational study. SETTING: Tertiary level outpatient clinics. PARTICIPANTS:
Children and youth with CP (N=60; 32 boys, 28 girls; mean age, 11.2y [range,
5-18y]), Gross Motor Function Classification System (GMFCS) level I to IV.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The 10-item ABILOCO-Kids
questionnaire, the 1MWT, and the 6MWT. RESULTS: ABILOCO-Kids logit scores were
significantly correlated with the 1MWT (rho=.70, P<.01) and the 6MWT (rho=.70,
P<.01) but not with age or sex. Linear models revealed a possibly significant
difference in the strength of the relationship of the ABILOCO-Kids logit score
with walking distance, depending on GMFCS level (P=.06 1MWT; P=.14 6MWT). The
strongest relationship was observed at GMFCS level II, where ABILOCO-Kids score
predicted 33% of variance in 1MWT (P=.003) and 31% of 6MWT (P=.003). The weakest
relationship was at GMFCS level I, where ABILOCO-Kids score predicted only 5% of
the variance in 1MWT (P=.33) and 16% of the variance in 6MWT (P=.08).
CONCLUSIONS: Parental perceptions of their child's walking ability in the
community correlate with clinic-based walking tests in ambulatory children with
CP, providing evidence of convergent validity for the 1MWT and 6MWT. However,
parents report a much wider range of walking abilities in children who function
at a high level (GMFCS I) than is reflected by their walk test results.
