The purpose of this study was to determine whether a higher electrical conductance exists at bilateral points on the auricles for dysmenorrheic subjects and whether this higher conductance would be reversed after a single treatment with acupuncture-like transcutaneous electrical nerve stimulation (TENS). The electrical conductance at four bilateral auricular acupuncture points was measured with a Staodyn Insight for 21 dysmenorrheic and 13 nondysmenorrheic women. The dysmenorrheic subjects participated in a separate study using TENS to relieve menstrual pain. Auricular conductance was assessed before and after a 30-min treatment for dysmenorrheic and 30 min rest for nondysmenorrheic subjects. Two-way analyses of variance and correlation coefficients were calculated. Tests indicated that statistically significant higher conductance does not exist for dysmenorrheic compared with nondysmenorrheic subjects and does not decrease after a decrease in menstrual pain. Results indicate that pain from dysmenorrhea is not reflected in a higher conductance at auricular acupuncture points.
