title: [A report on location of head acupoints by bone-length measurement in 100 persons].
abstract: OBJECTIVE
  To compare the differences between bone-length measurements on human head and to probe proportion relation of the position of head points.
  
  
  METHODS
  One hundred healthy adult volunteers, aged between 18-25 years, 50 males and 50 females, were randomly selected, and their height, body weight, the distances from Shenting (GV 24) to Toulinqi (GB 15), from Shenting to Touwei (ST 8), between bilateral Touwei (ST 8), between the two Mastoid, from Yintang (EX-HN 3) to front hairline, front hairline to Naohu (GV 17), Naohu to Fengfu (GV 16), Fengfu to the middle of rear hairline were measured respectively with standard measure instruments, and the proportion relation between bone-length measurement location and the point position were compared.
  
  
  RESULTS
  There was a significant difference between the distance of bilateral Touwei and the distance of the two Wangu (P<0.05). The proportion relation of Shenting-Toulinqi, Shenting-Touwei, bilateral Touwei distances basically conformed to the bone-length measurement location, while in the proportion relation of the distances of Yintang-front hairline, front hairline-Naohu, Naohu-Fengfu, Fengfu-the middle of rear hairline and the bone-length measurement location there were some differences.
  
  
  CONCLUSIONS
  Bilateral Touwei distance is not same as the bone-length measurements between two Mastoid, and Toulinqi can be located at the middle point of the connecting line of Shenting and Touwei. There is a certain deviation between marker location of Naohu, Fengfu and other points on body surface and the bone-length measurements.
