Abstract
Aim: We investigated the validity of the Gait Outcomes Assessment List (GOAL), as an assessment of gait function in children with cerebral palsy (CP).
Method: We studied a prospective cohort of 105 children with CP (Gross Motor Function Classification System [GMFCS] levels I-III; 65 males, 40 females; mean [SD] age 11y 11mo [3y 5mo], range 6-20y), who attended gait assessment over a 10-month period. Parents completed the GOAL, Functional Mobility Scale (FMS), and Functional Assessment Questionnaire (FAQ) during their child's gait evaluation. Ninety children completed instrumented gait analysis (IGA). Total GOAL and domain scores, Gait Profile Score (GPS), and Gait Variable Scores were calculated.
Results: The total GOAL discriminated between GMFCS levels (mean [SD] GMFCS level I, 72.5 [12.7]; GMFCS level II, 61.4 [13.0]; GMFCS level III, 38.8 [10.6]; [F2,97 =42.4, p<0.001]). Moderate correlations were found between total GOAL and FMS (5m and 50m r=0.59; 500m r=0.66) and FAQ walking (r=0.77) and activities list (r=0.75, p<0.01). There was a moderate negative correlation between total GOAL and GPS (r=-0.59) and gait appearance domain and GPS (r=-0.52, p<0.01).
Interpretation: The GOAL is a valid assessment of gait function in ambulant children with CP. It has the potential to improve understanding of the child's and parents' priorities and thus, in conjunction with IGA, provide a more balanced assessment across the domains of the World Health Organization's International Classification of Functioning, Disability and Health.
What this paper adds: The Gait Outcomes Assessment List (GOAL) can discriminate between Gross Motor Function Classification System levels. The GOAL correlates with standard functional assessments and gait analysis. Used with gait analysis, the GOAL provides comprehensive assessment across all International Classification of Functioning, Disability and Health domains.
