Motor outcome after perinatal stroke and early prediction of unilateral spastic cerebral palsy

Area of Science:

• Pediatric Neurology
• Developmental Pediatrics
• Neonatology

Background:

• Perinatal stroke affects 30%-68% of infants, often leading to unilateral spastic cerebral palsy (USCP).
• Early identification of USCP is crucial for timely intervention and improved outcomes.
• This study investigates predictive tools for USCP in infants post-perinatal stroke.

Purpose of the Study:

• To evaluate motor outcomes in infants following perinatal stroke.
• To assess the predictive value of the General Movements Assessment (GMA) and Hand Assessment for Infants (HAI) for USCP detection.
• To establish early screening methods for USCP.

Main Methods:

• A prospective observational study of infants with perinatal stroke.
• General Movements Assessment (GMA) administered between 10-15 weeks post-term age (PTA).
• Hand Assessment for Infants (HAI) performed between 3-5 months PTA, with motor outcomes assessed between 12-36 months PTA.

Main Results:

• Out of 46 infants, 15 (32.6%) were diagnosed with cerebral palsy (CP), including 13 with USCP.
• Abnormal GMA showed 85% sensitivity and 52% specificity for USCP; sensitivity reached 100% with asymmetric findings, but specificity dropped to 43%.
• A Hand Assessment for Infants (HAI) asymmetry index cut-off of 23 demonstrated 100% sensitivity and specificity for detecting USCP.

Conclusions:

• Both GMA and HAI can predict USCP in infants with perinatal stroke before 5 months of age.
• The HAI is a highly accurate screening tool for early detection of asymmetry and prediction of USCP.
• GMA interpretation requires caution in this specific infant population.
