Movement of a paralysed arm with yawning
 

Peter Kang, Amar Dhand

Chat-logomini

A 63-year-old man presented with aphasia and right arm paralysis (Medical Research Council [MRC] grade 0), sparing the leg. With yawning, his right arm consistently rose to his chest. Paralysis resumed after yawning. MRI confirmed an acute ischemic stroke in the left middle cerebral artery distribution. This movement ceased after 2 weeks following partial recovery of arm strength (MRC grade 4).
 
This phenomenon, first described in the 1844, was recently coined parakinesia brachialis oscitans. It is speculated to be a release event in which damaged cortical pathways no longer inhibit phylogenetically older brainstem pathways stimulated by yawning.1,2

Figure MRI Diffusion-weighted imaging (A) and apparent diffusion coefficient (B) sequences confirm acute ischemic infarct. These images show involvement of cortical and subcortical structures in the distribution of the left middle cerebral artery vascular territory.
