VAS Questionnaire

The VAS (Visual Analog Scale) Questionnaire is a tool used to measure subjective experiences, such as pain or discomfort, in a clear and straightforward way. It typically consists of a line, usually 10 centimeters long, where one end represents "no pain" and the other "worst pain imaginable." Respondents mark a point on the line indicating their level of pain. The position of the mark is then measured, providing a numerical score that helps healthcare providers understand the severity of a person's experience, track changes over time, and tailor treatment accordingly.
