Lhermitte's sign, sometimes called the Barber Chair phenomenon, is an electrical sensation that runs down the back and into the limbs. In many patients, it is elicited by bending the head forward. It can also be evoked when a practitioner pounds on the posterior cervical spine while the neck is flexed; this is caused by involvement of the posterior columns.
The sign suggests a lesion of the dorsal columns of the cervical cord or of the caudal medulla. Although often considered a classic finding in multiple sclerosis, it can be caused by a number of conditions, including transverse myelitis, Behçet's disease, trauma, radiation myelopathy, vitamin B12 deficiency (subacute combined degeneration), and compression of the spinal cord in the neck from any cause such as cervical spondylosis, disc herniation, tumor, and Arnold-Chiari malformation. Lhermitte's Sign may also appear during or following high dose chemotherapy. Irradiation of the cervical spine may also evoke it as an early delayed radiation injury, which occurs within 4 months of radiation therapy.
This sign is also sometimes seen as part of a "discontinuation syndrome" associated with certain psychotropic medications, such as serotonin reuptake inhibitors, particularly Paroxetine and Venlafaxine. Typically, it only occurs after having taken the medication for some duration, and then stopped or withdrawn rapidly. Fluoxetine, given its very long half-life, can be given as a single small dose, and often avoid Lhermitte's sign and other withdrawal symptoms.
In the dental field, three studies (Layzer 1978, Gutmann 1979, Blanco 1983) have identified Lhermitte's sign among nitrous oxide abusers.
This is the image of my Cervical spine. Does it show anything like spondolosis or anything else. Please comment
