Compression of the upper spinal cord, multiple sclerosis, transverse myelitis, Behçet's disease, osteogenesis imperfecta In neurology , Lhermitte phenomenon , also called the barber chair phenomenon , is an uncomfortable "electrical" sensation that runs down the back and into the limbs.
Subacute compression develops over days to weeks. Acute compression develops within minutes to hours. Acute compression may follow subacute and chronic compression, especially if the cause is abscess or tumor. Regardless of the pace, spinal cord compression will predictably progress over time.

This contributes to narrowing the spinal canal and compressing the spinal cord in the corresponding region. Herniated disk due to tearing of the spinal disk over time, causes the disk to protrude and exert pressure on surrounding spinal nerve tissue. Consequent compression on the spinal cord at the cervical region causes CSM. [12]
In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential narrowing of the spinal cord, increasing pressure and inducing damage on the spinal nerve roots, thus, causing paing, tingling or weakness in the lower ...
When due to trauma, myelopathy is known as (acute) spinal cord injury. When inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy. In Asian populations, spinal cord compression often occurs due to a different, inflammatory process affecting the posterior longitudinal ligament. [citation needed]
Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim's disease, [2] [3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks. [6] However, in many patients, dural ectasia is ...
Neurogenic shock results from damage to the spinal cord above the level of the 6th thoracic vertebra. [5] It is found in about half of people who have a spinal cord injury within the first 24 hours, and usually persists for one to three weeks. [5] Neurogenic shock may be caused by severe brain injury. [6]
