It typically consists of a straight line, usually 10 cm long, with endpoints labeled as extremes of the sensation being measured (e.g., 'no pain' at one end and 'worst pain imaginable' at the other).
The Visual Analogue Scale (VAS) is usually a horizontal line, 100 mm in length, anchored at each end by nonstandardized verbal descriptors which represent extreme limits of pain intensity (e.g., upper scale anchors: “most pain” [20], “pain as bad as it could be” [33]).
Visual analogue scales (VAS) are 10-cm lines anchored at the ends by words that define the bounds of various pain dimensions. The patient is asked to place a vertical mark on the scale to indicate the level of intensity of his or her pain, anxiety, depression, etc.
A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.
