Glossary of Terms

Ambulant
Walking, able to walk.
Anterior cord syndrome
An incomplete lesion when only the front of the spinal cord is damages, almost always at the cervical level.
Aperient
See laxative
Arachnoiditis
Thickening and scarring of the membranes which surround and protect the nerve roots. Cysts or adhesions develop, causing pressure on the cord, back pain and/or additional loss of nerve function. It can be caused by diseases such as meningitis and tuberculosis of the spine. More commonly it develops in people with spinal cord injury, or who have had operations on the spine. In the past it was often caused by the use of oil-based dyes injected into the spinal column to make myelograms. These dyes are no longer used. Milder forms of arachnoiditis are now believed to be the cause of the chronic back pain suffered by many able bodied people.
AUS
Artificial urinary sphincter - an inflatable cuff surgically fitted around the neck of the bladder, controlled by a pump located in the scrotum or labia.
Automatic bladder
Where the nerve impulses between the bladder and the spinal cord remain intact and the bladder can be trained to empty by reflex action.
Autonomic
The 'vegetative' nervous system which is separate from, but linked to that of the spinal cord. It controls the bladder and bowels, blood circulation and sweating.
Autonomic dysreflexia
Sudden increase in blood pressure to which tetraplegics are especially prone because their autonomic nervous system is disrupted. commonly caused by an over-full or infected bladder or bowel, it produces sweating and a blinding headache. It is a medical emergency, and if untreated can cause death.
Baclofen pump
A pump and reservoir implanted to deliver a measured dose of the drug Baclofen to the spinal cord to suppress spasm.

Syringomyelia
A condition affecting some able-bodied as well as some people with spinal cord injury. A cavity in the spinal cord fills with cerebrospinal fluid. The resulting pressure further enlarges the cavity and damages the nerve tissues in the cord.
