For most children with Arthrogryposis, treatment can significantly improve how they can move and what they can do. An Arthrogryposis (arth-ro-grip-OH-sis) diagnosis means a child is born with joint contractures. This means some of their joints don’t move as much or as normal joints move; joints may even be fixed in one position. Often the muscles around these joints are thin, weak, stiff, or missing. OTs help improves independence in daily activities by adapting to a child’s tasks or routines or by using adaptive equipment designed especially for that child.
