The invention provides a method capable of readily discriminating pathologic conditions and judging selection of a therapeutic drug, the degree of the therapeutic effect, discontinuation of medication, etc. Briefly described, a means for providing a proper hookswitch transition for a variety of international phone standards is provided. A sleeve is included within the stanchion bore, such that the sleeve is infinitely adjustable between two positions and lockable with respect to the stanchion. At least one of the values is then optionally compared to a low threshold and at least one of the values is also optionally compared to a high threshold, although any threshold may be used.
