Insights

The STEP protocol, focusing on motor skills and participation, is feasible for at-risk infants. It significantly improved motor skills and participation engagement compared to standard interventions.

Area of Science:

  • Developmental Pediatrics
  • Early Intervention Programs
  • Motor Development

Background:

  • Infants at biological risk are susceptible to developmental delays.
  • Early intervention is crucial for optimizing outcomes in at-risk infants.
  • The STEP protocol integrates motor skills, environmental factors, and participation for enhanced development.

Purpose of the Study:

  • To assess the feasibility of the STEP protocol in infants at biological risk.
  • To evaluate the preliminary effects of the STEP protocol on motor skills and participation.
  • To compare the STEP protocol with a standard intervention for at-risk infants.

Main Methods:

  • A randomized controlled trial involving 28 infants aged 3-9 months at risk for developmental delay.
  • Intervention groups: STEP protocol (n=14) and Standard Intervention (n=14), with parent-led delivery.
  • Outcome measures included the Alberta Infant Motor Scale (AIMS), Young Children's Participation and Environment Measure (YC-PEM), and Affordances in the Home Environment for Motor Development (AHEMD-IS).

Main Results:

  • The STEP protocol demonstrated good recruitment and retention rates.
  • The STEP group showed significantly higher scores on the AIMS (motor skills) post-intervention (p=0.014).
  • Significant improvements were observed in participation frequency (p=0.02) and engagement (p=0.03) for the STEP group compared to the standard intervention.

Conclusions:

  • The STEP protocol is a feasible and effective intervention for infants at biological risk.
  • The findings highlight the importance of integrating specific motor skill stimulation, participation, and family involvement in early interventions.
  • The STEP protocol shows superior outcomes compared to standard interventions, suggesting its potential for broader clinical application.
