FAMILIAL CONGENITAL MIRROR MOVEMENTS: REPORT OF A LARGE 4-GENERATION FAMILY

Abstract

Mirror movements (MM) are synkinesias occurring in the opposite side during the intentional use of a limb. They are occasionally present in children, but persistence after age 10 is abnormal. 1,2 We have found a large 4-generation family with congenital mirror movements not associated with other neurologic abnormalities.
