Developmental Outcomes in Children With Clubfoot: A Twin Study Comparing Affected and Unaffected Siblings

Area of Science:

• Pediatrics
• Developmental Psychology
• Orthopedics

Background:

• Clubfoot is a common congenital birth defect affecting 1-2 per 1000 live births.
• Treatment typically involves the Ponseti method or surgery.
• Understanding potential developmental delays in affected children is crucial for early intervention.

Purpose of the Study:

• To investigate whether children with clubfoot experience developmental delays compared to their unaffected siblings.
• To assess cognitive and motor development in children with clubfoot.

Main Methods:

• Evaluated 26 children (13 twin pairs) aged 6 months to 7 years using the Mullen Scales of Early Learning (MSEL).
• MSEL assesses gross motor, fine motor, visual perception, receptive language, and expressive language domains.
• Analyzed results using paired comparisons and normative benchmarks.

Main Results:

• No statistically significant differences were found in cognitive or motor development between children with clubfoot and their unaffected siblings.
• Minor, non-significant differences were noted in specific domains, with no consistent trends favoring either group.
• Affected children had slightly higher visual reception scores, while unaffected siblings had slightly better receptive language scores.

Conclusions:

• This study suggests that effectively treated clubfoot does not significantly impact cognitive or motor developmental milestones.
• Findings indicate that children with clubfoot may achieve comparable developmental outcomes to their unaffected peers.
• Further research with larger sample sizes is warranted to confirm these findings.
