Stimulus Parameter Considerations and Individual Differences in Cutaneous Sensitivity to Electropulse Stimulation

Abstract

The two experiments described were concerned with defining the optimal parameter values for an electropulse stimulus and the extent of S differences. In Exp. I, touch and pain threshold variations were established on 12 Ss as a function of pulse number (1, 4, 8) and pulse duration (0.5, 1.0 msec). Significant support was obtained for use of a single pulse of 0.5-msec. duration. In Exp. II, touch and pain thresholds were obtained on 20 Ss coincident with body region and session variation. The abdomen and chest appear to be ideal electrode sites. S differences over time were discussed.
