The Hoffmann sign or reflex is commonly taught as part of the physical examination to detect abstract upper motor neuron pathology. We present a case of a patient with congenital spinal stenosis and a fall who had a positive Hoffmann sign as the result of a central cord syndrome. The materials contain a video of this physical exam finding and briefly review its history, reliability and clinical utility.
