ABSTRACT
PURPOSE: To assess intra- and interrater reliability of the Spanish version of the 88-item Gross Motor Function Measure (GMFM-SP-88), and its correlation to age and severity of children with cerebral palsy. METHODS: Six raters assessed 50 videotapes and 4 viewed 50 recordings to determine intra- and interrater reliability, respectively. Intraclass correlation coefficients (ICCs), standard error of measurement (SEm), smallest real difference (SRD), and limits of agreement (LoA) were calculated. RESULTS: Intra- and interrater reliability were excellent for both total (ICC2,1 = 1.00, 95% confidence interval [CI] 0.99-1.00) and dimension scores (ICC2,1 = 0.99, 95% CI 0.99-1.00). The SEm and the SRD for the total score were acceptable (1.60 and 3.14, respectively). The average differences in dimension scores were below 1 and 0.1 points (95% LoA: -1.65 to 1.94, -1.06 to 0.86 for intra- and interrater reliability, respectively). CONCLUSIONS: The results support the potential use of the GMFM-SP-88 as a reliable tool, having correlation with age and severity. WHAT THIS ADDS TO THE EVIDENCE: The GMFM-SP-88 is a reliable outcome measure to assess gross motor function in cerebral palsy. The GMFM-SP is the only tool available in Spanish to assess gross motor function in children and adolescents with cerebral palsy. The GMFM-SP-88 is a valuable resource for both Spanish physical therapists and researchers.

PURPOSE: To review the level of evidence of the psychometric properties of outcome measures for motor or functional skills for children with cerebral palsy classified across I to V levels of the Gross Motor Function Classification System. METHODS: A systematic search was completed in PubMed/MEDLINE, ISI Web of Science, CINAHL, and 4 complementary databases. The COSMIN Risk of Bias checklist and the updated criteria for good measurement properties were applied to assess the quality. RESULTS: Four outcome measures were identified from 12 articles: Gross Motor Function Measure, Gross Motor Performance Measure, Pediatric Evaluation of Disability Inventory, and Functional Independence Measure for Children. Evidence levels for validity, reliability, and responsiveness varied among measures. CONCLUSIONS: Gross Motor Function Measure in all versions was the most investigated measure providing the best results, with the strongest evidence for validity and responsiveness properties. Reliability evidence should be improved to determine stability.
