[Method and current situations on acupuncture clinical trial registration in the world].

Acupuncture clinical trial registration can help improving the quality, internationalization and influence of acupuncture clinical trials.

The registered clinical trials mainly involve researches on pain management, functional disorders of an organ or system, etc. But most of the acupuncture clinical trials conducted in mainland China have not been registered and the trials quality needs being improved. The registration method is introduced in this paper.
