Currently, the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) remains the primary tool for assessing neurological impairment after injury. However, based on the inherent limitations of the ISNCSCI exam, accurate and sensitive biomarkers are required. Understanding the role of biomarkers in SCI is crucial for improving diagnosis, prognosis, and treatment strategies.

The international panel discussed the scope, utility, and application of biomarkers in SCI clinical trials and clinical practice. This article summarizes key insights from this discussion, highlighting the value of various types of biomarkers, ranging from molecular and cellular markers to those reflecting neural circuits, systems, and movement.
