Visual Analogue Scale of pain (VAS). VAS is presented as a ruler with a movable cursor, the length being approximately 10 cm. “0” represents “No pain,” while “10” represents “Agonizing.” When the test began, subjects moved the cursor to the position on the ruler that best represented the degree of pain they were currently experiencing.
