This document summarizes a study that evaluated the effects of Modified Constraint Induced Therapy (MCIT) on the affected upper extremities of children with mild to moderate spastic hemiplegic cerebral palsy. 30 participants were randomly assigned to either a MCIT group or a conventional therapy group.

MCIT thus proved to be more effective at improving function of
