Assessment and Early Intervention in the Neonatal Intensive Care Unit for a Preterm Infant With Williams Syndrome.

Williams syndrome (WS) is a rare genetic disorder that affects multiple body systems and can lead to developmental delays. Early physical therapy intervention may improve neurodevelopment outcomes for newborns with WS. This case report evaluates the impact of physical therapy on the motor and sensory development of a preterm infant with WS following discharge from the neonatal intensive care unit (NICU). Physical therapy assessments were performed at one, three, and five months of age using the Alberta Infant Motor Scale (AIMS). Interventions were individualized to improve muscle strength, reflex integration, and sensory processing, and parents received guidance on home-based activities. Results showed significant growth in weight (from 3460 g to 4900 g) and length (from 51 cm to 60 cm), along with improvements in the head and chest circumference. Motor skills and reflexes, as indicated by AIMS assessments, also demonstrated improvement (p < 0.05). The infant's general health condition also improved, including the frequency and consistency of stools and the success of feeding. This case report demonstrates the effectiveness of physical therapy in improving the motor and sensory development of a newborn with WS syndrome. The combination of individualized techniques and a cooperative environment between health professionals and parents was key to the success of the intervention. Further research is needed to confirm these findings and to determine the long-term effects of early intervention on the development and well-being of these individuals.
