A Case with Distinct Propagated Sensation along the Meridian (PSM) IV: the Variation of PSM according to Stimulation Methods, the Propagating Speed of PSM, and the Blocking Effect of Mechanical Pressure

Various acupuncture stimulations were given to a 60 year-old housewife with a distinct meridian phenomenon to observe subsequent PSM. Clear PSM was induced either by finger pressure, press needle or low frequency press needle stimulation of Guanchong (terminal point). Scarless moxibustion applied to a source point induced clearer PSM than that to a terminal point. Comparing the propagating speeds of the PSM induced by press needle stimulations of the terminal points of the twelve meridians, those of liver, kidney and spleeen were the fastest (about 70cm/sec) and those of heart and large intestine were the slowest (1cm/sec). The propagation of PSM was blocked by 50-60mmHg of manchette pressure or by about 400g/cm local pressure using a pressure meter.
