The International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) are endorsed by the International Spinal Cord Society (ISCoS) and the American Spinal Cord Injury Association (ASIA). Whilst ISNCSCI has existed for nearly 30 years, there remains ongoing confusion about aspects of the assessment and classification. There is also a common misunderstanding about the definition of a “complete” injury with most reverting back to the old Frankel definitions. The situation is confounded by recent changes and updates on important aspects of the ISNSCI. Yet clearly it is important that ISNCSCI data collected as part of routine care and/or research are accurate. This short presentation highlights some of the recent changes and idiosyncrasies of the ISNCSCI. It will focus on the distinction between AIS B and AIS C, and the new rules around the use of asterisks, “not determinable” and high cervical sensory loss in the face of normal upper limb strength.
