Visual analogue scales: scale recalibration by patients with dementia and their proxies

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...

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...

Vertical or horizontal visual analogue scales.

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.

A Comparison of Iran and UK EQ-5D-3L Value Sets Based on Visual Analogue Scale

Background Preference weights for EQ-5D-3L based on visual analogue scale (VAS) has recently been developed in Iran. The aim of the current study was to compare performance of this value set against the UK VAS-based value set.   Methods The mean scores for all possible 243 health states were compared using Student t test. Absolute agreement and consistency were investigated using concordance co...
