Schoolboy who writes and eats with feet

14-year-old Devin McLane from Stevensville, Montana, USA, suffers from Arthrogryposis Multiplex Congenita, a condition that causes curved joints, muscle weakness and stiffness. Most of the muscles in Devin's shoulders do not work and his arms hang limp at his sides. He is forced to walk on his tip toes and increasingly relies on a wheelchair to help him get around school.
