Visual Analog Scale
The Visual Analog Scale (VAS) is a tool used to measure subjective experiences, such as pain or feelings. It typically consists of a straight line, often 10 centimeters long, where one end represents "no pain" or "no discomfort" and the other end represents "the worst pain imaginable." Individuals mark a point on the line that reflects their level of pain or discomfort. The distance from the "no pain" end to the mark is then measured, providing a numerical value that helps healthcare providers assess and track the patient's experience over time.
