To date, much research has been conducted to measure needle manipulation quantitatively and objectively. This study was performed to quantitatively measure the differences in the amount of stimulation caused by various rotation frequencies and angles in twisting-rotating acupuncture needle manipulation.
The torque force exerted on a tissue was measured at various rotation frequencies and angles by rotating a needle with a needle force measurement system attached to a needle insertion tissue model.
The results show that with rotation frequency at 60°, the torque force increased significantly from 0.023 N mm to 0.118 N mm as the rotation angle increased ( < 0.05). In addition, the torque force was significantly increased from 0.082 N mm to 0.292 N mm when the rotation angle increased from 60° to 180° at 0.15 Hz. ( < 0.05). A strong linear positive relationship between the torque force and rotation angle or frequency was obtained [Pearson correlation coefficient () > 0.88; < 0.001].
The change in needle-tissue interaction force by rotating angles showed a tendency to be higher than those by rotation frequency. Further quantitative research on various manipulations will be required for a standardized education on manipulation and stimulation as well as on needle model development to become possible.
迄今为止，已经进行了大量研究以定量和客观地测量针刺手法。本研究旨在定量测量捻转补泻手法中不同旋转频率和角度所引起的刺激量差异。
通过连接到针插入组织模型的针力测量系统旋转针，在不同旋转频率和角度下测量施加在组织上的扭矩力。
结果表明，在60°旋转频率下，随着旋转角度增加，扭矩力从0.023 N·mm显著增加到0.118 N·mm（P<0.05）。此外，当在0.15 Hz下旋转角度从60°增加到180°时，扭矩力从0.082 N·mm显著增加到0.292 N·mm（P<0.05）。扭矩力与旋转角度或频率之间获得了很强的线性正相关关系[皮尔逊相关系数（r）>0.88；P<0.001]。
旋转角度引起的针-组织相互作用力变化趋势高于旋转频率引起的变化趋势。为了实现手法和刺激的标准化教育以及针模型的开发，需要对各种手法进行进一步的定量研究。
