Parakinesia brachialis oscitans: report of three cases.
The term 'parakinesia brachialis oscitans' (PBO) was coined recently to describe cases of hemiplegia in which spontaneous yawning causes involuntary raising of the affected upper limb. The authors report three additional cases of PBO adding new phenomenological findings to the syndrome, discussing possible physiopathology of this phenomenon.
