To investigate the effects of different acupuncture manipulations on Deqi sensations and surface myoelectricity, and explore the correlation between Deqi sensations and needling manipulations.
Forty-five healthy participants accepted twirling, lifting-thrusting, and twirling plus lifting-thrusting manipulanions at right Zusanli (ST 36), respectively. The acupuncturist's and participants' Deqi sensations were collected by MGH Acupuncture Sensation Scale (MASS). The intensity and occurrence rate of soreness, dull pain, pressure, heaviness, fullness, numbness, sharp pain, warmth, coolness, and throbbing feelings of participants, and tightness, smooth, and tangle feelings of acupuncturist were measured. The correlation between the acupuncturist's and participant's Deqi sensations was analyzed. Surface electromyogram (EMG) were recorded before, during and after needling in 30 participants. The integrated EMG (iEMG), mean power frequency (MPF) and media frequency (MF) were analyzed.
Both fullness and soreness of participants and tightness of acupuncturist were the most frequently occurred ones. A positive correlation between participants' fullness and acupuncturist's tightness was observed during the three aforementioned needling manipulations (P<0.05, OR>1). Almost all the needling sensations measured in the present study could be induced by the three needling manipulations. However, strength of Deqi sensations was exhibited as lifting-thrusting > twirling plus lifting-thrusting > twirling according to MASS index. The iEMG values were increased and MPF, MF values were decreased during needling compaired to those before needling, especially during lifting-thrusting (P<0.01).
The intensity and occurrence rate of the different Deqi sensations induced by different needling manipulations were basically similar. The fullness and soreness were both the most frequently induced Deqi sensations. The strongest Deqi sensation could be induced by lifting-thrusting manipulation. There is a positive correlation between participants' fullness and acupuncturist's tightness during the three needling manipulations. The myoelectricity around the acupoint is related to Deqi responses. (Registration No. AMCTR-IOR-20000314).
探讨不同针刺手法对得气感觉和表面肌电的影响，探索得气感觉与针刺手法之间的相关性。
45 名健康志愿者分别接受右足三里（ST36）捻转、提插和捻转提插手法，采用 MGH 针刺感觉量表（MASS）收集针灸师和参与者的得气感觉。测量参与者的酸痛、钝痛、压痛、沉重感、饱满感、麻木感、刺痛感、温热感、凉爽感和悸动感，以及针灸师的紧绷感、光滑感和纠结感的强度和发生率。分析针灸师和参与者得气感觉的相关性。30 名参与者在针刺前、针刺时和针刺后记录表面肌电图（EMG）。分析整合肌电图（iEMG）、平均功率频率（MPF）和中频（MF）。
参与者的饱满感和酸痛感以及针灸师的紧绷感是最常发生的感觉。在这三种针刺手法中，观察到参与者的饱满感与针灸师的紧绷感呈正相关（P<0.05，OR>1）。本研究中测量的几乎所有针刺感觉都可以由这三种针刺手法引起。然而，根据 MASS 指数，得气感觉的强度表现为提插>捻转提插>捻转。与针刺前相比，针刺时 iEMG 值增加，MPF、MF 值降低，尤其是提插时（P<0.01）。
不同针刺手法引起的不同得气感觉的强度和发生率基本相似。饱满感和酸痛感是最常引起的得气感觉。提插手法可引起最强的得气感觉。在这三种针刺手法中，参与者的饱满感与针灸师的紧绷感之间存在正相关。穴位周围的肌电与得气反应有关。（注册号：AMCTR-IOR-20000314）。
