Abstract:

Abstract This paper describes the use of an instrument called the Surface Scanning Laser Displacement Meter to detect, measure and record what appears to be cranial rhythmic impulse in several acupuncture points on a hand of a living human subject and to correlate the acupuncture pulsation of MUE49 of the right middle finger with the cranial motion obtained at the mastoid bone as detected and recorded with the same technique simultaneously. This research has proven objectively the presence of sinusoidal wave pulsation at the tip of the right mastoid bone (with a maximum deflection of 0.8 mm), the frequency of which is well within the range of cranial rhythmic impulse. Furthermore, this work has demonstrated objectively the presence of pulsations (with a maximum deflection of 0.07 mm and frequency range from 4 to 11 cpm) at several acupuncture points, the characteristics of which appear to be identified with the characteristics of the cranial rhythmic impulse. The characteristics of pulsations recorded from the tip of the right mastoid and the acupuncture point at the dorsal surface of the acupuncture point MUE49 of the right middle finger simultaneously appear to be similar. Incidentally, the experiment discovered a larger deflection of 0.25 mm with the frequency of almost one per minute (almost one wave per minute) which may indicate another type of body pulsation which has never been clearly identified or recognized previously. No significant bodily ill effects or influences upon the primary respiratory mechanism were noted during these experiments. Although correlation of pulsations recorded with this instrument with cranial rhythmic impulse detected by direct cranial palpation was not done, these experiments prove objectively the presence of pulsations at several acupuncture points and at the tip of the right mastoid bone. It is to be hoped that further well designed studies in the future using the same methods can clearly establish without any reasonable doubt that the pulsations recorded in these experiments are indeed the cranial rhythmic impulse.
