The propagated sensation along channels (PSC) was investigated in 1000 cases of randomly drawn individuals (including 15-60 aged, different occupational, healthy and sick subjects) by employing a low frequency electric pulse stimulator and silver plate skin electrodes at the Jing (well) point and the Yuan (source) point of the 12 major channels. Sometimes additional electrodes were used for relay of the propagation if necessary. Half of the 12 major channels including the Lung, Large intestine, Pericardium, Sanjiao, Spleen and Urinary Bladder Channels were pre-examined. The direction and course of PSC stated by the subjects were registered, while the subjects showed two channels with full length of PSC or three with partial length of PSC passed over the elbow or knee joints were re-investigated by the same method on all the 12 major channels.
According to the extent of PSC of each channel and the number of channels with full length of PSC registered, the subjects were divided into four groups and their percentage in the population of 1,000 cases were calculated as: (1) marked group 1.3%, (2) moderate group 1.8%, (3) mild group 15.2%, (4) non PSC group 81.7%. The data which were statistically analysed led to the following conclusions: (1) the sum of the percentages of the three groups of subjects with PSC is 18.3%. It shows that the phenomenon of PSC is rather common in its occurrence. While the percentage of the marked group is 1.3% and its distribution follows Poisson's distribution (the 95% confidence limits estimated 0.6-2.0%). It implies that the subjects with marked PSC are not very rare. (2) The differences of the distribution of each group between the male and female as well as the healthy and sick subjects are statistically insignificant.
Owing to the limitations of our testing method the percentages of the moderate group and mild groups in this report are likely lower than the actually existing value. Based on the results of this analysis it may be concluded that the occurrence of the subjects with marked PSC and the phenomena of PSC are not only objective but also rather common. They were shown in the people of different age, sex and health conditions. So further studies would be of significance in exploring the substratum of the theory of the channels and collaterals.
