Capitalizing on Early Brain Plasticity

The first 24 months of life represent a unique "window of opportunity" for children with unilateral cerebral palsy, a condition that impairs muscle control on one side of the body. New research from the NIH-funded Baby CHAMP study (Children with Hemiparesis Arm-and-Hand Movement Project) demonstrates that delivering high-dose, play-based therapy during this period can lead to significant, lasting improvements in motor skills. Led by researchers at the Fralin Biomedical Research Institute at VTC, the trial highlights the remarkable adaptability of the developing nervous system when exposed to structured, intensive intervention.

Comparing Constraint vs. Bimanual Approaches

The trial rigorously compared three distinct therapist-delivered interventions for children aged 6 to 24 months:

Constraint-Induced Movement Therapy (CIMT) - Full-time: The stronger arm is placed in a cast to encourage use of the weaker arm.

CIMT - Part-time: A splint is worn on the stronger arm only during therapy sessions.
