Problem
Morgan is a 9 year old with cerebral palsy (CP). He is unable to hold a pencil for writing or drawing. His hand posture is typical for a CP child: flexed wrist and digits, thumb across the palm, moderate spasticity. His mother is very involved with Morgan's care and wellbeing and is excited about the possibility of Morgan being able to write or draw. What type of orthotic is indicated to help Morgan hold a writing tool?
