The American Spinal Injury Association (ASIA), formed in 1973, publishes the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), which is a neurological exam widely used to document sensory and motor impairments following spinal cord injury (SCI). The ASIA assessment is the gold standard for assessing SCI. ASIA is one of the affiliated societies of the International Spinal Cord Society. The completeness or incompleteness of the injury is measured by the ASIA Impairment Scale (AIS).
