Summary
The Functional Dexterity Test (FDT) is reliable and valid for assessing fine motor skills in children. This clinical measurement study confirms its utility for tracking progress in pediatric hand function.
Area of Science:
- Pediatric occupational therapy
- Clinical measurement science
- Hand function assessment
Background:
- The Functional Dexterity Test (FDT) lacks validation in pediatric populations.
- Accurate assessment tools are crucial for monitoring hand function in children.
- Early intervention for congenital hand differences necessitates reliable outcome measures.
Purpose of the Study:
- To establish the reliability and validity of the Functional Dexterity Test (FDT) in children.
- To assess the FDT's suitability for pediatric use.
- To provide a validated tool for measuring fine motor dexterity in young individuals.
Main Methods:
- Clinical measurement study design.
- Interrater and test-retest reliability assessed using Intraclass Correlation Coefficients (ICCs) in typically developing children.
- Concurrent validity established by correlating FDT scores with the Jebsen-Taylor Hand Function Test (JHFT) and activities of daily living (ADL) tasks in children with congenital hand differences.
Main Results:
- The FDT demonstrated excellent interrater (ICC=0.99) and test-retest (ICC=0.90) reliability.
- FDT scores showed significant correlations with JHFT fine dexterity subsets (r > 0.67) and ADL tasks (good to excellent).
- Discriminant validity was supported by significantly higher FDT speeds in typically developing children compared to those with congenital hand differences (P < .001).
Conclusions:
- The Functional Dexterity Test (FDT) is a valid and reliable instrument for measuring fine motor dexterity in children.
- The FDT can effectively track functional progress, monitor treatment efficacy, and provide feedback to families.
- This validated tool supports early intervention and management of pediatric hand conditions.
