Evaluation of the use of visual analogue scale in chinese patients

Abstract

The linear analogue score can be used in Chinese patients with relative accuracy provided it has been well explained. The error from employing a vertical presentation is significantly less than that from a horizontal one. The choice of upward or downward orientation is a matter of convenience. Younger patients and those with higher intelligence are quicker to understand the concept and can make better judgement in placing a mark where they wish it to be. A linear analogue scale seems to be a suitable method to record and study pain in a Chinese population.
