The aim of this study was to explore the effects of different acupuncture insertion velocities.
This study was performed as a within-subject design to control for individual differences. The biomechanical properties of needle insertion and accompanying subjective acupuncture perception was compared between different insertion velocities.
The setting for this study was the laboratory of acupuncture meridian and functional neurology, Acupuncture and Meridian Science Research Center, Kyung Hee University.
Sixteen (16) healthy volunteers participated in the study.
An acupuncture needle was inserted to the acupoint LI4 by an acupuncture needle insertion device (ANI-KY) at high or low speed of needle insertion.
Biomechanical properties such as force and depth were measured online by sensors equipped with the ANI-KY device. Participants filled out a questionnaire about acupuncture sensation or perception.
Acupuncture needle insertion at a higher velocity was linked with higher maximum power, lower level of pain, and de qi-like perceptions such as "compressing" and "heavy" (p<0.05).
These results suggest that needle insertion velocity might be a factor for controlling inadvertent pain during the acupuncture needling process and that biomechanical properties of needling may be related to acupuncture perception or sensation.
本研究旨在探讨不同针刺入速度的影响。
本研究采用自身对照设计，以控制个体差异。比较了不同刺入速度下针刺的生物力学特性和伴随的主观针刺感觉。
本研究的地点是庆熙大学针灸经络与功能神经科学实验室，针灸经络科学研究中心。
16 名健康志愿者参加了这项研究。
使用一种针刺入装置（ANI-KY）以高或低的针刺入速度将针刺入 LI4 穴位。
通过配备 ANI-KY 装置的传感器在线测量力和深度等生物力学特性。参与者填写了一份关于针刺感觉或知觉的问卷。
针刺入速度较快与更高的最大功率、更低的疼痛程度以及“压迫”和“沉重”等类似得气的感觉相关（p<0.05）。
这些结果表明，针刺入速度可能是控制针刺过程中意外疼痛的一个因素，针刺的生物力学特性可能与针刺感觉或知觉有关。
