A Study of the Relative Precision of Acupoint Location Methods

The Journal of Alternative and Complementary Medicine, 2002
This study examined the relative precision of four methods of acupoint location: two traditional methods (directional and proportional) and two contemporary methods (elastic and ruler).Seventy-two (72) subjects attempted to locate a fictitious acupoint (FP) with repeated attempts and the resulting coordinates were recorded.The research was carried out ...
