--but in most of the clinical application papers I've read that describe the procedure, it's referred to as quantitative, inasmuch as what is being looked at are thresholds for noticing pain as temperatures are increased/decreased, and also the JND--the just noticable difference at which one can discern that the temperature has actually changed.

A fairly consistent finding in this testing (probably the most consistent finding) is that people with small-fiber damage have to have the temperature increased/decreased by a greater amount than do "normals" to say they've noticed an actual change.
