EQUIPMENT AND SERVICES

 A

Ambulant
    Walking, able to walk.
Ankylosing spondylitis
    Arthritis of the spine.
Anterior cord syndrome
    A lesion in the spinal cord that causes loss of movement, pain and temperature sensitivity, but preserving proprioception. See Preprioception
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 longed 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 (spastic) action.
Autonomic
    The ´unconscious´ 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
    An autonomic reflex causing a sudden, severe, increase in blood pressure in response to pain or discomfort, usually originating below the level of paralysis. Tetraplegics are more prone to this complication as their autonomic nervous systems are unable to oppose the reflex. Commonly caused by an over-full bladder or bowel it presents as profuse sweating, flushing and a blinding headache. It is a medical emergency, and if untreated can cause death.

  B

Baclofen pump
    A pump and reservoir implanted to deliver a measured dose of the drug baclofen to the spinal cord to suppress spasm.
Bladder neck closure
    An operation to close off the urethra and neck of the bladder and insert a suprapubic catheter.
Brown-Séquard syndrome
    Occurs when one side of the spinal cord is damaged, common when injury is caused by a stab wound. On the injured side of the body there is reduced movement and reflexes, while on the opposite side there is a loss of sense of pain and temperature.
Bursa, bursitis
    A pocket of fluid which collects between tissue and the bone, caused by pressure or bumps, and which can cause a pressure sore.

  C

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 of the cord. In SCI people this tends to occur above the level of the original injury, causing pressure on nerve roots and pain or further loss of sensation in upper limbs.
