[The control of somesthesia caused by neuroreflex stimulation: quantification of stimulus response as opposed to energy].

Introduction: In the reflexotherapy of classical acupuncture it is usually claimed that below a certain level of stimulation, which is determined by the appearance of a peculiar sensation known as De-Qi, no appreciable therapeutic effect is obtained. The control exerted by the afferences over the central nervous system, however, do not work in this way, but instead adjust themselves, albeit with certain peculiarities, to a classical pattern of proportionality between stimulus and response. Our aim is, therefore, to evaluate the extent to which increasingly intense acupuncture stimuli can modify neurophysiological parameters in a way that also grows.
