337 children with post-poliomyelitic sequalae were tested for propagated sensation along channels (PSC) by the method of electric pulse stimulation of the Jing (well) points. Those with PSC passing up to or above elbow and/or knee were considered to be positive. Such was the case in 83 of the 377 patients (22%). For control, 129 healthy children were tested in the same way but none of them were positive. In another group of 100 children with other diseases, only 2% were positive. The above data revealed a strikingly higher rate in the post-poliomyelitic group.


With respect to the positive rates in the various channels, those in the foot six channels were significantly higher than those in the hand six channels, being even higher in the affected side. Among the foot six channels the Stomach Channel was at the uppermost.

38 children with the phenomenon of positive PSC had received various orthopedic operations such as elongation of the tendon Achilles, quadriceps transfer and so on and 174 PSC positive channels were traversed by the operative procedures. Re-examinations one week post-operatively revealed that 113 channels (65%) had their PSC pathways disappeared, shortened or distorted; the other 61 (35%) remained unchanged.  It is speculated that the changes might be due to surgical damage to the soft tissue including skin, muscle, tendon and fascia which in traditional Chinese medicine are collectively called: "Twelve Jingjin" , "Twelve Pibu", hence the phenomenon of PSC might be very closely related to them.
