ASIA Impairment Scale (AIS)

A five-grade classification (A through E) describing spinal cord injury severity from the ASIA examination, based on completeness and sacral sparing, where A is a complete injury and E is normal sensory and motor function.

Related: Neurological level of injury, Sacral sparing, Zone of partial preservation
Neurological level of injury

The most caudal spinal cord segment with intact sensory and motor function on both sides, determined by the ASIA examination; it may differ from the skeletal level of fracture seen on imaging.

Related: ASIA Impairment Scale (AIS), Zone of partial preservation, ASIA motor score
Sacral sparing

Preserved sensation at the anal mucocutaneous junction, deep anal pressure, or voluntary anal sphincter contraction, which marks an injury as incomplete and generally predicts better neurological recovery.

Related: ASIA Impairment Scale (AIS), Neurological level of injury
Zone of partial preservation

The spinal segments below the neurological level that retain some sensory or motor function in a complete injury; by definition it is recorded only when no sacral sparing is present.

Related: ASIA Impairment Scale (AIS), Neurological level of injury
ASIA motor score

The sum of manual muscle test grades from 0 to 5 for ten key muscles on each side, giving a total from 0 to 100 that is used to track motor recovery over time.

Related: Neurological level of injury, ASIA Impairment Scale (AIS)
Spinal shock

Transient flaccid paralysis with loss of all reflexes below the injury immediately after cord trauma, lasting days to weeks and considered ended when the bulbocavernosus reflex returns.

Related: Neurogenic shock, ASIA Impairment Scale (AIS)
Neurogenic shock

Hemodynamic instability after cervical or high thoracic injury from loss of sympathetic tone, producing hypotension with bradycardia or an absent compensatory tachycardia; treated with fluids, vasopressors, and atropine when needed.

Related: Spinal shock, Mean arterial pressure target, Orthostatic hypotension
Central cord syndrome

An incomplete injury, often from hyperextension of a stenotic canal, causing greater weakness in the arms than the legs with variable sensory loss and a generally favorable but incomplete prognosis.

Related: Brown-Séquard syndrome, Anterior cord syndrome, ASIA Impairment Scale (AIS)
Brown-Séquard syndrome

Hemisection of the cord producing ipsilateral motor and proprioceptive loss with contralateral loss of pain and temperature sensation beginning one or two levels below the lesion.

Related: Central cord syndrome, Anterior cord syndrome
Anterior cord syndrome

Damage to the anterior cord from flexion injury or vascular compromise, causing bilateral loss of motor function and pain-temperature sensation while posterior column proprioception and light touch remain intact.

Related: Central cord syndrome, Brown-Séquard syndrome
Cauda equina syndrome

Injury below the conus involving lumbosacral nerve roots, producing asymmetric lower motor neuron weakness, saddle anesthesia, and bowel or bladder dysfunction; acute cases require urgent surgical evaluation.

Related: Conus medullaris syndrome, Clean intermittent catheterization
Conus medullaris syndrome

Injury at the terminal cord near L1 with symmetric findings, early and prominent bowel and bladder dysfunction, and a mixture of upper and lower motor neuron signs in the legs.

Related: Cauda equina syndrome, Clean intermittent catheterization
SCIWORA

Spinal cord injury without radiographic abnormality, seen mainly in children whose elastic spinal ligaments stretch and recoil; magnetic resonance imaging may reveal cord edema or hemorrhage.

Related: ASIA Impairment Scale (AIS), Mean arterial pressure target
Mean arterial pressure target

Guideline-recommended maintenance of mean arterial pressure at roughly 85 to 90 mmHg for about seven days after acute injury to support cord perfusion, although evidence for the best target remains limited.

Related: Neurogenic shock, Spinal shock
Autonomic dysreflexia

A potentially life-threatening syndrome in injuries at T6 or above with sudden severe hypertension, headache, flushing, and bradycardia triggered by noxious stimuli below the lesion, most often bladder distention.

Related: Detrusor sphincter dyssynergia, Orthostatic hypotension, Pressure injury staging
Detrusor sphincter dyssynergia

Involuntary contraction of the external urethral sphincter during bladder contraction, producing high storage pressures, incomplete emptying, and risk of upper urinary tract damage.

Related: Clean intermittent catheterization, Autonomic dysreflexia
Clean intermittent catheterization

Scheduled bladder emptying with a single-use catheter, preferred for neurogenic retention because it lowers infection rates and pressure-related renal risk compared with an indwelling catheter.

Related: Detrusor sphincter dyssynergia, Neurogenic bowel program, Autonomic dysreflexia
Neurogenic bowel program

A scheduled routine combining diet, fluids, oral or rectal medications, and timed evacuation techniques, tailored to reflexic upper motor neuron or areflexic lower motor neuron bowel patterns.

Related: Clean intermittent catheterization, Autonomic dysreflexia
Pressure injury staging

An international classification running from stage 1 nonblanchable erythema through stage 4 full-thickness loss with exposed fascia, muscle, or bone, plus unstageable and deep tissue injury categories.

Related: Autonomic dysreflexia, Aging with SCI
Heterotopic ossification

Formation of lamellar bone in soft tissue, usually around the hips or knees weeks to months after injury, causing swelling, warmth, and restricted motion, often with elevated alkaline phosphatase.

Related: Spasticity, Pressure injury staging
Orthostatic hypotension

A fall of at least 20 mmHg systolic or 10 mmHg diastolic on standing or head-up tilt, common after cervical injury from lost sympathetic vasoconstriction and managed with gradual mobilization, compression, and medication.

Related: Neurogenic shock, Tilt table, Autonomic dysreflexia
Syringomyelia

A fluid-filled cavity within the cord that may enlarge years after injury, producing ascending sensory loss, new weakness, or pain; magnetic resonance imaging confirms it and surgery may be required.

Related: Spasticity, Aging with SCI
Spasticity

A velocity-dependent increase in muscle tone from hyperexcitable stretch reflexes after upper motor neuron injury, managed with stretching, positioning, oral medications, chemodenervation, or intrathecal baclofen.

Related: Heterotopic ossification, Functional electrical stimulation
Functional electrical stimulation

Application of electrical current to paralyzed nerve or muscle to produce contraction, used for cycling, grasping, standing, and bladder or bowel assistance after spinal cord injury.

Related: Tenodesis grip, Body-weight supported treadmill training
Tenodesis grip

Passive finger flexion generated by active wrist extension in a person with C6 tetraplegia, allowing grasp without finger flexor control; training and splinting can optimize the pattern.

Related: Functional electrical stimulation, Transfer training
Body-weight supported treadmill training

Locomotor practice with partial body-weight unloading and manual or robotic assistance, intended to activate spinal locomotor circuits and improve stepping in incomplete injuries.

Related: Functional electrical stimulation, Tilt table
Tilt table

A device that gradually raises a patient toward upright to improve orthostatic tolerance, provide weight bearing, and assess cardiovascular response before standing or gait training.

Related: Orthostatic hypotension, Body-weight supported treadmill training
Transfer training

Structured practice of moving between surfaces such as bed, wheelchair, and toilet using preserved strength, balance, and technique; it strongly influences discharge destination and independence.

Related: Tenodesis grip, Community reintegration
Community reintegration

Return to participation in work, school, recreation, relationships, and civic life after injury, measured with instruments such as the CHART and supported by accessible housing and transportation.

Related: Vocational rehabilitation, Caregiver burden
Caregiver burden

The physical, emotional, and financial strain experienced by family or paid helpers of a person with spinal cord injury, which predicts depression and institutionalization and warrants separate assessment and support.

Related: Depression screening, Community reintegration
Depression screening

Routine use of validated instruments such as the PHQ-9 to detect treatable mood disorder, which occurs two to three times more often after spinal cord injury than in the general population.

Related: Caregiver burden, Peer support
Vocational rehabilitation

Coordinated services including work assessment, retraining, workplace accommodation, and job placement that help a person with spinal cord injury return to or enter competitive employment.

Related: Community reintegration, Peer support
Peer support

Assistance from mentors who have lived with spinal cord injury, offering practical advice, role modeling, and hope; it is associated with better adjustment and self-management.

Related: Depression screening, Community reintegration
Aging with SCI

The earlier and accelerated onset of conditions such as shoulder overuse, osteoporosis, cardiovascular disease, and pressure injury in long-term survivors, requiring proactive screening across the lifespan.

Related: Osteoporosis after SCI, Pressure injury staging
Osteoporosis after SCI

Rapid bone loss below the injury level during the first one to two years, especially at the distal femur and proximal tibia, raising low-trauma fracture risk; bisphosphonates and weight bearing may help.
