A 100 Mm Visual Analogue Scale Used In Main Study Vertical Reference A visual analogue scale (vas) is one of the pain rating scales used for the first time in 1921 by hayes and patterson [1]. it is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms. for example, the amount of pain that a patient feels ranges across a continuum from none to an extreme. The nrs is a segmented numeric version of the visual analog scale (vas) in which a respondent selects a whole number (0–10 integers) that best reflects the intensity of their pain . the common format is a horizontal bar or line ( 23 ).
Vertical Visual Analogue Scale 1. introduction. the visual analogue scale (vas) has been in use for the measurement of intangible quantities such as pain, quality of life and anxiety since the 1920s [1]. it consists of a line usually 100 mm in length, with anchor descriptors such as (in the pain context) “no pain” and “worst pain imaginable”, depicted in fig. 1. The visual analogue scale (vas) is the most frequently used method to assess pain intensity. the scale is usually a horizontal (joyce et al 1975; huskisson et al 1983) or vertical 10 cm line (sriwatanakul et al 1983) labelled at each end by descriptors such as ‘no pain’ and ‘worse pain ever’ (fig. 3.1). Objectives. the visual analogue scale (vas) has been used in the context of health and healthcare for various purposes, for example, to measure pain and to provide a single index measure of health related quality of life (hrqol). this scoping review aims to describe how the vas has been used for health state valuation in the published literature. The visual analog scale (vas) is a simple, 1 dimensional (1 d) scale that measures pain intensity (fig. 1). it is a 10 cm horizontal line with word anchors on either end. the word anchors can be changed to represent different dimensions of pain. 7 the anchors most commonly used in pain studies are “no pain” and “worst possible pain.”.

Vertical and horizontal visual analogue scales have been compared in the measurement of pain. there was a good correlation between the 2 scales, but the scores from horizontal scales tended to be slightly lower than those from vertical scales. Each scale is 100 mm in length. nursing best practice guideline scale a: horizontal visual analogue scale how much shortness of breath are you having right now? please indicate by marking the line. if you are not experiencing any shortness of breath at present, circle the marker at the left end of the line. scale b: vertical visual analogue scale.
