ASIA Impairment Scale (AIS) / ISNCSCI

ISNCSCI 2019 · Motor Score + AIS Grade · SCI Classification Standard

Key Muscle Motor Scores (0–5 MRC)

C5Elbow Flexors (Biceps)

C6Wrist Extensors (ECRL)

C7Elbow Extensors (Triceps)

C8Finger Flexors (FDP-mid)

T1Finger Abductors (ADM)

L2Hip Flexors (Iliopsoas)

L3Knee Extensors (Quads)

L4Ankle Dorsiflexors (TA)

L5Long Toe Extensors (EHL)

S1Ankle Plantarflexors (Gastroc)

AIS Grade (Clinician Assessment)

Motor Incomplete — Motor function preserved below NLI; at least half of key muscles graded ≥ 3.

SCI Classification

Enter motor scores for all 10 key muscles and select AIS grade.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Classify neurological level and completeness of spinal cord injury at admission and follow-up

Determine motor and sensory neurological level of injury (NLI)

Establish AIS grade for prognosis, research stratification, and rehabilitation planning

Required by all SCI research registries (NACTN, NINDS, European MultiCenter SCI)

Monitor neurological recovery as outcome measure in SCI clinical trials

Gold Standard

The ISNCSCI (International Standards for Neurological Classification of SCI) is the universally accepted system developed by the American Spinal Injury Association (ASIA). Endorsed by ISCoS, ASIA, WHO, and all major SCI registries globally. Updated in 2019 with clarifications to non-key muscle function and zone of partial preservation (ZPP) definitions.

When Not to Use

Unconscious or uncooperative patients — motor/sensory testing requires patient participation

Within first 72 hours of injury during spinal shock — AIS grade may not reflect true injury severity until spinal shock resolves

Pre-existing peripheral neuropathy (e.g., diabetes) — may confound sensory levels

Non-traumatic SCI with progressive disease — ISNCSCI designed for stable neurological injuries; use with caution in progressive myelopathy

Related Scores in Practice

In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the Scim Iii, Wisci Ii, Bristol Stool Chart, Uems or the Neurogenic Bladder Symptom Score (NBSS) to formulate a comprehensive care plan.
