The visual analogue scale for the measurement of pain is not linear


The October 2005 issue of the Anaesthesia and Intensive Care contains this letter in its correspondence section by K Pesudovs, MJ Craigie and G Roberton in response to an article by Myles and Urquhart entitled The linearity of the visual analogue scale in patients with severe acute pain. Included is a reply by Myles and Urquhart.


Valid and effective methods for measuring pain are vital for outcomes research into pain management given the absence of objective measurement.

However, we dispute the interpretation of their data being supportive of linearity of the visual analogue scale (VAS).
