近年来

国內许多单位通过临床治疗和对大量人群的调查

对循经感传现象进行了广泛的观察和研究

肯定了循经感传现象的客观存在。但它的本质目前还不清楚

存在着不同的看法。曾经有人观察列

单独给以电针The objective of this study is to observe the possibility of elaborating a conditioned reflex on the basis of propagated sensation along channels (PSC).Eleven subjects with marked PSC were observed. A rhythmic sound was used as neutral stimulus which was reinforced by PSC arisen from stimulating Hegu or Waiguan. The results of total 40 experiments revealed that the conditioned reflex could not be established under the circumstances. Galvanic skin response (GSR) was recorded simultaneously in 4 cases among them. The feature of GSR also showed that conditioned reflex had never been established yet. In a special case

EMG from preauricular region was used as a responsive indication of PSC. Therefore

the results of the experiments could be evaluated by EMG records objectively. However

no sign of formation of conditioned reflex appeared. The facts mentioned above suggest that the conditioned reflex could scarcely be established on the basis of PSC.
