How should we use the visual analogue scale (VAS) in rehabilitation outcomes? III: On the validation requirements for assessments using VAS with ratio properties.

Use of visual analogue scales.

G. R. V. HUGHES plates. Sixteen wells 3 mm in diameter and 1-5 mm apart are cut in a row, and a trough 3 mm wide is cut parallel to the wells 3 mm from their cathodal side. Heat inactivated sera (8 .lI) are added to the wells, and a tissue extract containing soluble antigens (150 ,ul) is placed in the trough. We use human spleen extract4 or rabbit thymus extract at a final protein concentration...

The use of the Visual Analogue Scale (VAS) in rehabilitation outcomes.

The Visual Analogue Scale (VAS) is a common form of response option in health outcome studies, often used to measure pain, amongst other things, and is generally presented as a single line of 100 mm with anchor words at either end (e.g. no pain – worst possible pain). It was first published in the early 1920's (1, 2) though not widely used at that time (3). There are variations on the VAS theme...

Can stroke patients use visual analogue scales?

BACKGROUND AND PURPOSE Visual analogue scales (VAS) have been used for the subjective measurement of mood, pain, and health status after stroke. In this study we investigated how stroke-related impairments could alter the ability of subjects to answer accurately. METHODS Consent was obtained from 96 subjects with a clinical stroke (mean age, 72.5 years; 50 men) and 48 control subjects without...

The validation of visual analogue scales as ratio scale measures for chronic and experimental pain.

Visual analogue scales (VAS) of sensory intensity and affective magnitude were validated as ratio scale measures for both chronic and experimental pain. Chronic pain patients and healthy volunteers made VAS sensory and affective responses to 6 noxious thermal stimuli (43, 45, 47, 48, 49 and 51 degrees C) applied for 5 sec to the forearm by a contact thermode. Sensory VAS and affective VAS respo...
