Visual analogue scales.

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.

Can stroke patients use visual analogue scales?

METHODS Consent was obtained from 96 subjects with a clinical stroke (mean age, 72.5 years; 50 men) and 48 control subjects without...

Visual analogue scales: a source of error.

BACKGROUND In earlier studies, pain assessment in patients with Alzheimer's disease (AD) was conducted by interview, for which reliability is questionable considering the decline in expressive and receptive language abilities in AD. As similar language problems occur in young children, the reliability of pain assessment in this latter population is increased by employing visual analogue scales....
