A note on the digiti quinti sign in hemiplegic migraine

Abstract

The digiti quinti sign (DQS) was described as an indication of mild hemiparesis. It consists of a wider space between the fourth and fifth fingers at the affected side when the patient extends both arms horizontally to the front with the palms down. The three successively examined sporadic hemiplegic migraine patients presented herein disclosed no other neurological abnormality except the interictally present DQS on the same side of the motor deficits. This sign is perhaps clinically useful for the diagnosis of hemiplegic migraine. © Blackwell Publishing Ltd.
