Summary
This study provides updated motor test norms for children aged 6-14. Performance generally improved with age, with no significant sex differences except for grip strength in older boys.
Area of Science:
- Neuropsychology
- Pediatric assessment
- Motor function
Background:
- Standard motor tests like the Finger-Tapping Test, Grooved Pegboard Test, and Grip Strength Test are crucial in pediatric neuropsychology.
- Existing norms for these tests are often outdated, lack co-norming, and are based on limited, non-diverse samples.
Purpose of the Study:
- To establish updated, co-normed performance data for three common motor tasks.
- To provide these norms using a diverse pediatric sample.
Main Methods:
- Recruited 476 participants aged 6-14 from community settings.
- Administered the Finger-Tapping Test, Grooved Pegboard Test, and Grip Strength Test to all participants.
Main Results:
- Performance on motor tasks generally improved with age.
- No significant sex-based performance differences were found for the Grooved Pegboard Test or Finger Tapping Test.
- Boys aged 12-14 showed significantly stronger grip strength in their dominant hand compared to other groups.
Conclusions:
- The study successfully generated updated and co-normed data for frequently used pediatric motor assessments.
- These findings offer valuable, current normative data for clinicians working with diverse pediatric populations.
