Similar to De Qi psychophysical responses, propagated sensation along the channels (PSC) is considered an important phenomenon in traditional Chinese acupuncture. In acupuncture clinical trials, different acupuncture manipulation techniques are used to enhance the propagation of sensation along the channels to facilitate an optimum therapeutic result.
To examine and compare the PSC reported by participants in a clinical trial following the administration of acupuncture and inactive mock laser.
The study was embedded in a two-arm parallel design multicenter, randomized clinical trial, the Tennis Elbow Acupuncture-International Study-China, Hong Kong, Australia, Italy (TEA IS CHAI). Needle sensations were measured using a validated instrument, the Massachusetts General Hospital Acupuncture Sensation Spreading Scale. Ninety-six participants with lateral elbow pain were randomly allocated into two groups in a 1:1 ratio; the acupuncture treatment group (n = 47) and the mock laser control group (n = 49). Participants in both groups received the intervention at two acupoints, LI10 and LI11, consisting of 2 minutes of either standardized needle manipulation or mock laser at each acupoint with a rest period between each intervention period. Data were collected immediately following the interventions at the first and the ninth session within the clinical trial.
Although participants in both groups perceived PSC radiating to similar sites along the upper limb, the frequency of the reported radiation sites among the two intervention groups for both radiation up the limb (p < 0.05) and radiation down the limb (p < 0.001) were statistically significantly different. Among the radiating sensation sites recorded within the two study groups, the sensations were reported as radiating a greater distance down the forearm to the wrist compared to up the arm. Evaluation of PSC across the four study sites revealed a statistically significant difference in frequency of the reported radiation down the limb sites in each study group and radiation up the limb sites only in control group only (p < 0.001).
The findings of the study demonstrated that the PSC phenomenon is not just associated with needling but can be perceived when using a mock laser.

与得气的心理生理反应类似，循经感传被认为是中医针灸中的一种重要现象。在针灸临床试验中，会采用不同的针刺手法来增强循经感传，以促进达到最佳治疗效果。
在一项临床试验中，观察并比较参与者在接受针刺和非活性模拟激光治疗后报告的循经感传情况。
本研究纳入一项双臂平行设计的多中心随机临床试验，即网球肘针灸国际研究——中国、香港、澳大利亚、意大利（TEA IS CHAI）。使用经过验证的仪器——麻省总医院针刺感觉扩散量表来测量针感。96名患有外侧肘部疼痛的参与者按1:1比例随机分为两组；针刺治疗组（n = 47）和模拟激光对照组（n = 49）。两组参与者均在两个穴位（LI10和LI11）接受干预，每个穴位进行2分钟的标准化针刺操作或模拟激光治疗，每次干预之间有休息期。在临床试验的第一次和第九次治疗结束后立即收集数据。
尽管两组参与者都感觉到循经感传向上肢的相似部位放射，但两个干预组中报告的沿上肢向上放射部位（p < 0.05）和沿上肢向下放射部位（p < 0.001）的频率在统计学上有显著差异。在两个研究组记录的放射感部位中，与向上臂放射相比，感觉沿前臂向下放射到手腕的距离更远。对四个研究地点的循经感传评估显示，每个研究组中报告的沿肢体向下放射部位的频率以及仅在对照组中报告的沿肢体向上放射部位的频率在统计学上有显著差异（p < 0.001）。
该研究结果表明，循经感传现象不仅与针刺有关，使用模拟激光时也能感觉到。
