[Study on needling depth of Dazhui (GV 14), Jianzhongshu (SI 15), Xuanshu (GV 5) and Mingmen (GV 4) with CT].
OBJECTIVE
To provide reference for the safe needling depth of Dazhui (GV 14), Jianzhongshu (SI 15), Xuanshu (GV 5) and Mingmen (GV 4) in clinical acupuncture and moxibustion treatment.


METHODS
Thirty-two adult volunteers were divided into 3 groups, thin person group, moderate person group and fat person group according to Luo's indexes, and computer-aided tomography was used to measure the needling depth of Dazhui (GV 14), Jianzhongshu (SI 15), Xuanshu (GV 5) and Mingmen (GV 4).


RESULTS
The safe depths of perpendicular needling were different for persons of different somatotypes, for example the needling depth for Dazhui (GV 14) was (32.86 +/- 3.96) mm for the thin person group, (37.76 +/- 4.91) mm for the moderate person group, and (47.93 +/- 5.30) mm for the fat person group.
