Motor elements of the third month variously predict individual later motor elements.

Area of Science:

• Pediatric developmental neurology
• Infant motor development
• Clinical kinesiology

Background:

• Early motor development is crucial for overall child well-being.
• Identifying reliable early indicators can facilitate timely interventions.
• Understanding the relationship between early axial and distal motor patterns and later development is key.

Purpose of the Study:

• To investigate the correlation between axial and distal motor features at 3 months of age and subsequent motor development at 4-5 and 7-8 months.
• To establish the predictive value of early infant motor assessments for later developmental milestones.

Main Methods:

• Prospective qualitative evaluation of motor development in 93 infants (including premature infants) at 3, 4-5, and 7-8 months.
• Utilized the Quantitative and Qualitative Assessment of Motor Development Worksheet for 3-month assessments.
• Employed the Vojta development concept for qualitative assessments at 4-5 and 7-8 months.

Main Results:

• Significant correlations were found between 3-month axial features and later motor skills, such as asymmetric elbow support.
• Supine position observations at 3 months (midline crossing, grasping) correlated with correct pelvic and lower limb positioning.
• Early axial and distal elements are essential for achieving a qualitatively correct oblique sitting position by 7-8 months.

Conclusions:

• Axial motor features observed at 3 months are strong predictors of motor development at 4-5 months and show moderate correlations with development at 7-8 months.
• Proper spine development is fundamental for the development of shoulders and pelvis.
• Early assessment of axial motor features serves as a valuable indicator for motor progression and supports early intervention strategies.
