RESUMO
STUDY DESIGN: Cross-sectional. INTRODUCTION: The Functional Dexterity Test (FDT) is a timed pegboard hand dexterity test. Normative data have been developed primarily in adults with some studies in the pediatric population. The present study will complement the existing pediatric data and make the FDT a stronger assessment for use in this population. PURPOSE OF THE STUDY: The primary aim of this study was to collect normative data in typically developing children aged 3-5 years in the Greater Montreal area; the secondary aim was to evaluate the intrarater and interrater reliabilities of the FDT. METHODS: The FDT was administered to typically developing children aged 3-5 years, who were recruited from various geographical locations and socioeconomic status levels across the Greater Montreal area. Descriptive statistics, t-tests, and analysis of variance were used to compare age-gender groups. The intraclass correlation coefficient (ICC) was calculated to determine intrarater and interrater reliabilities. RESULTS: Normative data were collected from 267 children (137 females) from 18 daycares. Statistically significant differences in FDT scores were found across all age bands (P < .01). Total time decreased with increasing age (P < .01). No significant differences were found between genders. The FDT showed excellent interrater (ICC = 0.89-0.98) and intrarater (ICC = 0.83-0.99) reliabilities. CONCLUSIONS: The clear and standardized pediatric instructions, scoring sheet, and normative data table developed in this study provide health care professionals with quick and easy tools to facilitate scoring and clinical interpretation of hand dexterity in preschool-aged children. Future studies should include school-aged children and adolescents from a larger geographic area.
