A brachial plexus injury is often caused when an infant’s neck is stretched to the side during a difficult delivery. This injury results in partial loss of sensory and/or motor function of the involved arm. The Brachial Plexus program at the University of Michigan includes providing children with rehabilitation exercises. The problem presented to us was how to engage older children/teenagers and encourage exercising at home between visits. Numbered cards makes it easy for the therapist to give instructions to the child. Line illustrations by Karen Parker Moeller.
