Abstract
The visual analog scale (VAS) is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 100 mm horizontal line, and this rating is then measured from the left edge. The VAS score correlates well with acute pain levels, but it does have an error of about 20 mm.
Keywords: visual analog scale, Pain intensity, pain levels
