WebConstraint Induced Movement Therapy (CIMT) is a therapy technique to treat children who have neuromotor conditions that affect one side of their body. Sometimes CIMT is referred to as “movement therapy” or “constraint therapy.”. Some children who have neuromotor conditions avoid using two hands during play and other daily activities.
