Sintesi	The Visual Analog Scale (VAS) is a 10-centimeter line for measuring pain intensity, developed by Huskisson in 1974. Patients mark their current pain level along the continuum from no pain to worst pain imaginable. It remains one of the most widely used single-item pain measures in clinical practice and research.	The Glasgow Coma Scale (GCS), developed by Teasdale and Jennett in 1974, is a 15-point scale used to assess level of consciousness and severity of brain injury. It evaluates eye opening, verbal response, and motor response, making it the gold standard tool for rapid neurological assessment in trauma, emergency, and intensive care settings.	The Numeric Rating Scale (NRS) is a single-item, self-report measure of pain intensity developed by Jensen and colleagues in 1986. Patients rate their pain on an 11-point scale (0-10) where 0 represents no pain and 10 represents the worst pain imaginable. The NRS is among the most widely used pain severity measures in clinical practice and research due to its simplicity, rapid administration, and robust measurement properties.
