They're building arm muscles weakened from cerebral palsy or brain injury with an innovative new program at the University of Michigan. It's called CHAMP, which stands for Comprehensive Hand-Arm Movement Program.
It's helping kids with low muscle tone in their arms gain better control. Ironically, in this program, you have to give up your good arm. It is restrained in a removable cast or splint.
That forces the brain to figure out how to use the weaker arm, so that part of the brain is built up along with the arm muscles. Most kids wear the cast for up to 16 hours a day for three weeks. If this sounds familiar, the technique is also used to treat adult stroke patients.
