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 ...

BACKGROUND Vital sign data are important for clinical decision making in emergency care. Clinical Decision Support Systems (CDSS) have been advocated to increase patient safety and quality of care. However, the efficiency of CDSS depends on the quality of the underlying vital sign data. Therefore, possible factors affecting vital sign data quality need to be understood. This study aims to explo...
