Visual Analog Scale for Pain
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.
