Abstract

A radiant heat algometer system is described which enables the psychophysical and clinical study of cutaneous pain sensations and reactions by means of a precise, stabilized power source. In this system DC electric power consumption of a bulb is automatically controlled, and no calibration is necessary to be controlled frequently. Moreover, attention is drawn to the significance of using the blackened sticky tape and of the pre-heating procedure. The application of this algometer is also described for a pain threshold determination with the intensity and time methods.
