When first meeting a parent who's had a child newly diagnosed with cerebral palsy, I really want to try and help them understand their baby. It can be difficult for parents to take it in all at once and many leave that first interview quite overwhelmed, but you're going to meet some really important and helpful people.
Upper limb therapies and interventions have been well studied in cerebral palsy. Different interventions that have good evidence are Constraint Induced Movement Therapy (CIMT) and Bimanual Therapy. CIMT has been shown to be successful in children with hemiplegic cerebral palsy (CP). CIMT uses a splint to physically constrain the uninvolved arm and encourage them to use the more involved or affected arm.
