The present study is aimed at evaluating the effects of manual acupuncture with different durations on the human brain using functional magnetic resonance imaging.
Eighteen healthy right-handed volunteers were divided into three groups randomly. Each group received only one kind of acupuncture on the right LI4 (Hegu) point, which lasted 30 sec, 60 sec, or 180 sec, respectively. Fix-effect and conjunction analysis were used to compare the effects of the three kinds of acupunctures.
The results indicated that the stimulation of manual acupuncture with different durations could induce different effects in the central nervous system on the human brain. The longer duration of manual acupuncture might induce more significant areas.
The present study provided not only neuroimaging evidence for manual acupuncture, but also a useful guide for clinical applications of acupuncture. In addition, the results might be helpful to understand the relationship between the central nervous system responses and the durations of acupuncture.
本研究旨在利用功能磁共振成像评估不同时长的手动针刺对人脑的影响。
18名健康右利手志愿者被随机分为三组。每组仅在右侧合谷穴接受一种针刺，针刺时长分别为30秒、60秒或180秒。采用固定效应和联合分析比较三种针刺的效果。
结果表明，不同时长的手动针刺刺激可在人脑中的中枢神经系统诱导出不同的效应。手动针刺时长越长，可能诱导出的区域越显著。
本研究不仅为手动针刺提供了神经影像学证据，也为针刺的临床应用提供了有益指导。此外，研究结果可能有助于理解中枢神经系统反应与针刺时长之间的关系。
