Parakinesia Brachialis Oscitans due to Brain Stem Infarct

Abstract

In stroke patients, involuntary movements can occur both in the acute and chronic phase. Here, we describe one such involuntary movement consistent with the rare phenomenon of parakinesia brachialis oscitans (PBO). PBO has been reported in ischaemic and haemorrhagic strokes involving the anterior circulation; however, this is only the second time this phenomenon is being reported in posterior circulation stroke in the English literature.
