A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between “no pain” and “worst pain.”
Pain scales help you and your healthcare provider measure and track your pain. See the different pain scales in use and how they work to qualify and quantify your pain.
Both the Visual Analog Scale for Pain and the Numeric Rating Scale (NRS) for Pain are unidimensional single-item scales that provide an estimate of patients' pain intensity. They are easy to administer, complete, and score.
The visual analog scale (VAS) of pain intensity consists of a line, most often 100 mm long, with 2 descriptors representing extremes of pain intensity (eg, no pain and extreme pain) at each end.
The visual analogue scale (VAS) is commonly used as the outcome measure for such studies. It is usually presented as a 100-mm horizontal line on which the patient’s pain intensity is represented by a point between the extremes of “no pain at all” and “worst pain imaginable.”.

The visual time analog (VITA) scale aims to assess pain severity by measuring the amount of time spent in various pain states (blue: ‘unaware of pain’, red: ‘aware of nothing but pain’, yellow: between blue and red).
Correlation between Visual and verbal scale: 1-3 = mild pain; minimal impact on ADL’s. 4-6 = moderate pain; moderate impact on ADL’s. 7-10 = severe pain; major impact on ADL’s
The visual analogue scale (VAS) is a scale used to determine the pain intensity experienced by individuals. It consists of a line, approximately 10-15 cm in length, with the left side signifying no pain with a smiling face image and the right side signifying the worst pain ever with a frowning face image.
