Investigating the effects of three needling parameters (manipulation, retention time, and insertion site) on needling sensation and pain profiles: a study of eight deep needling interventions.

Introduction. In traditional Chinese acupuncture, needle sensation (deqi) is purported to contribute to a therapeutic outcome. While researchers have attempted to define deqi qualitatively, few have examined the effects of needling parameters on its intensity.

A study of the relative precision of acupoint location methods.

Objective: 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).

Design: Seventy-two (72) subjects attempted to locate a fictitious acupoint (FP) with repeated attempts and the resulting coordinates were recorded.

Location: The research was carried out at the Acupuncture Clinic of the University of Technology, Sydney (UTS).
