title: Arm levitation sign in acute right frontoparietal infarct.
abstract: We present the case of an 80-year-old female with acute right fronto-parietal stroke and an interesting neurological sign on clinical examination; the arm levitation sign. We discuss the imaging correlates of this sign and hypothesize on the possible functional etiology of the sign. We also discuss in brief, the possibility of neuronal misconnections causing the sign and the resultant problems with rehabilitation when patients have this sign.
