The survey has been done with 2107 cases including 788 healthy persons, 1211 clinical patients and 100 deaf-mutes. A round plate 0.5 cm in diameter pulse-electrode  was used for determination at the first period, and electrical Dizhen  was administrated in the latter. In all the tests short course relay stimulations were adopted. Four standard degrees were used for identifying the effects of PSC, i.e. marked, moderate, mild and none.


From the results of the surveying of 25,284 channels, it demonstrated that PSC appeared in different length, when the effective stimulation had been applied to the course of the channels. There was no difference of sex, age, occupation and race, though the majority of these cases were short PSC. Similar result was observed in Sudan and Mozambique, by physicians who had served there, and also in Japan. From the view point of the authors, PSC is considered to be not only a frequent, but also a common phenomenon over the population. It may appear in most people under suitable conditions (we call it Popularity of PSC).


The occurrence of PSC is conditioned to the body function and to appropriate stimulation. If these conditions are not prepared, PSC exists as recessive form. In our series, some cases with no PSC after stimulation, had effectuations on effect organs; some displayed either marked or mild, present or absent PSC variation, and some showed segmental or crossing over of PSC. These may be considered that the recessive form of PSC does really exist (we call it Recessive of PSC).


In accordance to the courses of the twelve channels many changes were seen in our instances. There were 111 PSC out of 471 showing deviations (23.5%) and in another group 41.3% out of 252 cases. Besides these, other phenomena were also observed such as convergence of several channels towards one or towards the affected area. Varieties in nature, direction, velocity, width, depth and intensity of PSC are very frequently seen (we call it variability of PSC). This character of variability implies that it is affected by exo- and endofactors and is an active equilibrium of the body.


The rate of occurrence of PSC of the patient group is 61.2% which is markedly higher than the healthy group of 40.5% (P<0.05), with higher rate in the affected channel group which showed 80% of occurrence (P<0.01), and in the group of PSC reaching the affected region (we call these manifestations Tendency of PSC). The effect organs reacted in various forms when PSC arrived, e.g. patient feeling hunger, heat or distention in the stomach when PSC reaches it and eyes lightening up with approaching PSC etc. (we call these actions Efficacy of PSC)


The properties of PSC such as direction of propagation, nature of sensation, development or disappearance etc. might be controlled by manipulations of pressing, following, pushing and shutting. The percentage of direction control is 96.8 out of 471 PSC (the control group 58.7%, P<0.01) and the percentage of control of arrival at the affected destination is 84.3 out of 711 PSC (control group 59.1%). PSC can be elicited after repeated short course relay stimulations and its nature can be regulated by manipulation has been familiar to us in the acupuncture field (we call it Regulatability of PSC).


In short the properties of PSC can not be separated and to study their significance is of great importance to the field of clinical practice and elucidation of the essence of channels.
