Parakinesia Brachialis Oscitans in a Patient With a First Manifestation of Multiple Sclerosis.

ABSTRACT:

Objectives

Parakinesia brachialis oscitans (PBO) is the involuntary movement of an otherwise paretic upper limb triggered by yawning. We describe the first case of PBO in a patient with a first manifestation of tumefactive multiple sclerosis (MS).
