PURPOSE : This study examined the effect of highfrequency transcutaneous electrical nerve stimulation (TENS) and San-Yin-Jiao (SP6) acupressure on primary dysmenorrhea. Furthermore, the difference in effectiveness between the two methods were compared.
METHODS : Twenty-six students participated in this study, and were randomly assigned to a high-frequency TENS group(experimental 1, n=9), a San-Yin-Jiao (SP6) acupressure group(experimental 2, n=9), and no treatment group(control, n=8). They were assessed and treated on the first day of their menstruation. The TENS protocol included applying 20 minutes of stimulation with a frequency of 100Hz, 100μsec pulse width. Four electrodes were placed on the skin 3 cm from midline at T12-L1 and S2-3 paravertebral muscles. San-Yin-Jiao (SP6) acupressure should be applied with the thumb for 10 minutes(8 seconds pressure and 2 seconds rest) on the SP6 acupoint. This procedure should be repeated for the other foot. Dysmenorrheal pain measured two pain assessment tools (VAS, DPT) pre-treatment; immediate post-treatment; 30minutes, 1, 2hours; and 3, 4, 5, 6, 24 hours after the VAS test were added.
RESULTS : The results showed significant differences in pain assessments (VAS, DPT) after treatment for subjects of experimental group1 (p<.05) and experimental group2 (p<.05), whereas the between-group comparison found no statistically significant differences.
CONCLUSION : This result supports the idea that using two methods could be effective in pain reduction among students who suffered from primary dysmenorrhea.
