The investigators hypothesize that the Traube-Hering-Mayer oscillation, measured by laser-Doppler blood flowmetry, is useful in aiding the understanding of the basic physiology of osteopathy in the cranial field.

Forty-four subjects were evaluated. It was determined that flowmetry provides frequency and signal power data, the interpretation of which is consistent with concepts of Cranial Rhythmic impulse (CRI) potency, fast and slow tides, and still points.
