Lhermitte俟Q製 sign was described by Marie and Chatelin and named after Jean Lhermitte. This sign is mostly described as an electric shock like condition by some patients of multiple sclerosis. This sensation occurs when the neck is moved in a wrong way or rather flexed. It can also travel down to the spine, arms, and legs, and sometimes the trunk. Demyelination and hyperexcitability are the main pathophysiological reasons depicted for the Lhermitte俟Q製 sign. Other causes for Lhermitte俟Q製 sign include transverse myelitis, behηet俟Q製 disease, trauma, etc. This article reviews the Lhermitte俟Q製 sign, its history, and its etiopathophysiology. Very few studies are available on Lermitte俟Q製 sign and more research need to be done on the same to ensure its sensitivity and specificity.
