Mirror movement (MM) is involuntary symmetrical movement observed in the limb contralateral to the voluntary limb movement. This movement is temporally observed in the developmental period of the healthy child, but then disappears. Continuation of this movement is considered abnormal, and hereditary, congenital or acquired MM has been reported with or without neurological disorders. Supplementary motor area, corpus callosum, and cervical lesions have been linked to MM. The pathomechanism of MM is speculated to be abnormal descending corticospinal pathways or impaired cortical and subcortical motor control systems in the brain, and both mechanisms may be present.
