在针灸治疗过程中，针灸针被操纵以引起特征性的“德气”反应，这被广泛认为是针灸治疗效果的关键。得气有一个生物力学的组成部分，“抓针”，我们通过测量60名人类受试者将针灸针从皮肤中拔出所需的力（拔出力）来量化。我们假设针双向旋转（BI）和单向旋转（UNI）的拔出力大于无旋转（NO）。使用计算机控制的针灸仪在八个穴位和八个控制点插入针灸针，操作和拔出。我们发现UNI和BI的平均拔出力分别比NO增加了167%和52%（重复测量ANOVA，P < 0.001）。拔出力在针刺点比对照点平均大18%（P < 0.001）。因此，抓针是一种可测量的生物力学现象与针灸针操作。
During acupuncture treatments, acupuncture needles are manipulated to elicit the characteristic "de qi" reaction widely viewed as essential to acupuncture's therapeutic effect. De qi has a biomechanical component, "needle grasp," which we have quantified by measuring the force necessary to pull an acupuncture needle out of the skin (pullout force) in 60 human subjects. We hypothesized that pullout force is greater with both bidirectional needle rotation (BI) and unidirectional rotation (UNI) than no rotation (NO). Acupuncture needles were inserted, manipulated, and pulled out by using a computer-controlled acupuncture needling instrument at eight acupuncture points and eight control points. We found 167 and 52% increases in mean pullout force with UNI and BI, respectively, compared with NO (repeated-measures ANOVA, P < 0.001). Pullout force was on average 18% greater at acupuncture points than at control points (P < 0.001). Needle grasp is therefore a measurable biomechanical phenomenon associated with acupuncture needle manipulation.
