the spin,it is made of a sequence of red circles, and is designed to avoid the use of numbers, it promotes clarity for patients with visual impairments.Most professionals prefer using an ordinal scale to the continuous VAS. others find numbers easier to use whereas others found the SPIN more helpful. the SPIN gives a reliable measure of pain intensity in patients fully able to communicate their views and experiences. Investigation in patients with cognitive or communication impairments is then neccessary.
