Using a ruler, the score is determined by mea-suring the distance (mm) on the 10-cm line between the “no pain” anchor and the patient’s mark, providing a range of scores from 0–100. 0 represents no dizziness … [1] From the patient's perspective, this spectrum appears continuous ± their pain does not take discrete jumps, as a categorization of none, mild, moderate and severe would suggest. This continuous (or "analogue") aspect of the scale differentiates it from discrete scales such as the Likert scale. [1][2] These advantages extend to measurement instruments made up from combinations of visual analogue scales, such as semantic differentials.
