Activities scale for kids: an analysis of normals

Several outcome tools have been developed to measure physical functioning in pediatric orthopedic patients. One such tool, the Activities Scale for Kids (ASK), allows assessment of physical functioning in the community in 5- to 15-year-olds. Previous validation of the ASK showed a significant difference in scores according to global ratings of disability. In this study, the ASK was administered to children without musculoskeletal disability to determine how normal respondents scored. ASK questionnaires were distributed to 137 children and 122 (89%) were returned. Normal children scored quite high, with a mean summary score of 93.12 (SD 6.45). This score differs significantly from the mean summary score for children with mild disabilities as determined in previous studies of disability (P = 0.005).
