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 with it to be. A linear analogue scale seems to be a suitable method to record and study pain in a Chinese population.
