The sensation of an electric shock described by Lhermitte has become accepted as an indication of cervical cord lesions and is described in most texts as elicited by neck flexion. This sensation may also occur in the presence of a thoracic cord lesion with trunk flexion. A patient had this symptom during trunk flexion, caused by documented extradural compression of the thoracic cord. After surgical decompression, the electrical shocks were no longer felt. The clinician is alerted to this symptom as an indication of a spinal cord lesion. More specifically it suggests a thoracic cord lesion if it is elicited by flexion of the trunk and not by flexion of the neck.
