VAS

The Visual Analogue Scale (VAS) is a psychomotor response tool used to measure subjective feelings and sensations on a 10 cm line with semantic opposites at each end. It is utilized for assessing pain, anxiety, mood, and other clinical symptoms, while also helping in medication dosage decisions. Although VAS is reliable and allows for quantitative measurement, it has limitations in comparing results across individuals and may exhibit low reliability in pain measurement.
