Without the movement, the pupil would develop contractures.
If the muscle spasms continue, they can cause contractures (damage to muscle and/or surrounding tissue, causing deformity at a joint ).
I taught self care, showed patients how to reduce contractures through exercise, and did ultrasound and splinting.
No joint contractures or skeletal muscle involvement are observed in these patients.
However, there is no congenital heart defect present and there are multiple contractures with overriding fingers observed with this syndrome.
