Cortical Plasticity in Spastic Diplegia After Selective Dorsal Rhizotomy

This study examines brain plasticity (how the brain reorganizes itself) in children with spastic diplegia — a form of cerebral palsy affecting both legs — before and after they undergo Selective Dorsal Rhizotomy (SDR), a surgery that cuts nerve roots to reduce muscle spasticity. You may be eligible if: - Your child has been diagnosed with spastic diplegia (cerebral palsy affecting both legs) - Your child is scheduled for or has had Selective Dorsal Rhizotomy surgery - Your child is between 3 and 18 years old You may NOT be eligible if: - Your child is not having Selective Dorsal Rhizotomy surgery Talk to your doctor to see if this trial is right for you.
