Cross-sectional study of gross and fine motor development. Birth to 6 years of age
Insights
This study assessed motor development in 187 children aged 0-6 years using a hybrid tool. Results showed emerging motor skills align with norms, but achieved skills often differ, highlighting developmental variations.
Area of Science:
- Pediatric Development
- Motor Skill Acquisition
- Child Psychology
Background:
- Understanding typical motor development is crucial for early identification of developmental delays.
- Existing motor assessments vary, necessitating a comprehensive and standardized approach.
- Normative data provides a benchmark for evaluating individual child development.
Purpose of the Study:
- To establish age-based performance distributions for gross and fine motor behaviors in children aged 0-6 years.
- To identify developmental patterns and milestones across early childhood.
- To compare the stability and accuracy of a novel assessment tool against existing literature.
Main Methods:
- A hybrid assessment instrument comprising 192 items from 15 established tools was administered to 187 healthy children (0-6 years).
- Emergence and achievement levels for 37 specific motor tasks were defined based on 68% and 95% performance rates within age ranges.
- Results were graphically analyzed to illustrate developmental patterns and compared with published norms from eight other assessment devices.
Main Results:
- Emergence of motor skills showed good agreement with existing published norms.
- Achievement of motor skills revealed notable discrepancies when compared to established norms.
- Graphical representations highlighted symmetrical and asymmetrical patterns in normal motor development milestones.
Conclusions:
- The study provides a detailed framework for understanding motor behavior distributions in early childhood.
- Discrepancies in achievement norms suggest a need for updated or refined assessment standards for motor development.
- The findings offer valuable insights for clinicians and researchers evaluating pediatric motor development and milestones.
Abstract:
A total of 187 healthy children between birth and six years of age were administered a comprehensive gross and fine motor development assessment. The assessment device was a hybrid instrument consisting of 192 items derived from 15 commonly used instruments. The purpose of the study was to 1) define motor behavior relative to a performance distribution expressed in age ranges, 2) identify patterns of performance across a range from birth to 6 years of age, and 3) assess the stability of performance by comparing select tasks with norms available in the literature. Emergence and achievement levels of successful performance were defined for 37 items relative to 68 percent and 95 percent of the children across the range from birth to 6 years of age. These results were compared with eight assessment devices. Emergence comparisons were found to be fairly similar to published norms; achievement comparisons showed a higher frequency of discrepancies with published norms. Performance patterns were displayed graphically to illustrate symmetry and asymmetry in normal development milestones.
