Sternocleidomastoid Test

Sternocleidomastoid Test

It has been reported that apparent weakness of the sternocleidomastoid muscle is common (80%) in functional hemiparesis, usually ipsilateral to the hemiparesis, whereas it is rare in vascular hemiparesis (11%), presumably because of the bilateral innervation of the muscle.
