visual analog scale

An instrument used to quantify a subjective experience, such as the intensity of pain. A commonly used visual analog scale is a 10-cm line labeled with “worst pain imaginable” on the right border and “no pain” on the left border. The patient is instructed to make a mark along the line to represent the intensity of pain currently being experienced. The clinician records the distance of the mark in centimeters from the left end of the scale.
