Insights
Infants with neonatal stroke (NS) show early delays in midline behaviors and motor skill development. This impacts their fine and gross motor abilities, highlighting the need for early intervention in high-risk infants.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Motor Control
Background:
- Hemiparesis and cerebral palsy often involve impairments in upper extremity movements, midline behaviors, and fine/gross motor skills.
- Early detection of motor deficits in at-risk infants is crucial for timely intervention.
- Neonatal stroke (NS) is a significant risk factor for developing hemiplegic cerebral palsy.
Purpose of the Study:
- To investigate midline toy exploration and fine/gross motor skills in infants at risk for hemiplegic cerebral palsy.
- To compare motor development between infants with neonatal stroke and typically developing infants.
- To identify early indicators of motor impairment in infants with NS.
Main Methods:
- Longitudinal assessment of 8 infants with NS and 13 infants with typical development (TD) from 2 to 7 months of age.
- Analysis of percentage of time infants spent engaging in midline behaviors.
- Evaluation of fine and gross motor skills using the Bayley Scales of Infant Development (BSID-III).
Main Results:
- Infants with NS demonstrated significantly poorer performance in midline behaviors compared to TD infants.
- Neonatal stroke group scored lower on both fine and gross motor skills assessments (BSID-III).
- These motor skill deficits were evident early in infancy, between 2 and 7 months of age.
Conclusions:
- Infants with neonatal stroke exhibit deficits in midline behaviors and overall motor skill development during early infancy.
- Poor midline behaviors in infants with NS may be an early sign of neurological impairment.
- Findings underscore the importance of early assessment and intervention for motor development in infants following neonatal stroke.
Abstract:
Upper extremity movements, midline behaviors, fine, and gross motor skills are frequently impaired in hemiparesis and cerebral palsy. We investigated midline toy exploration and fine and gross motor skills in infants at risk for hemiplegic cerebral palsy. Eight infants with neonatal stroke (NS) and thirteen infants with typical development (TD) were assessed from 2 to 7 months of age. The following variables were analyzed: percentage of time in midline and fine and gross motor scores on the Bayley Scales of Infant Development (BSID-III). Infants with neonatal stroke demonstrated poor performance in midline behaviors and fine and gross motor scores on the BSID-III. These results suggest that infants with NS have poor midline behaviors and motor skill development early in infancy.
