The purpose of this study wasto examine the effect of high-frequency Transcutaneous Electrical Nerve Stimulation (TENS) on primary dysmenorrhea and to compare it with placebo in a randomized controlled study.</p><p>Methodology: Sixty four female aged between 14-18 years at the first day of their menstruation cyclerandomly divided in two groups (TENS or placebo TENS). Participants' physical characteristics and menstrualhistory were recorded. Menstrual pain was measured by self-reported pain intensity using visualanalog scale (VAS) before and just after treatment. Paired t-test and independent t-test was conducted tocompare pain intensity between pre and post treatment between the two groups (TENS vs. placebo).</p><p>Results: The decrease in pain intensity after TENS and placebo TENS were both significant, (Active group:6.31 to 2.40, t= 9.70, p&lt;0.01; placebo group: 6.65 to 5.00, t= 5.97, p&lt;0.01). However, pain intensity inactive TENS was significantly decreased than the placebo group (t=-4.690, p=0.000). Concurrent use ofanalgesic was reduced significantly in the active TENS (t= 5.475, p&lt;0.01); but not after placebo TENS.</p><p>Conclusions: This result supports that using TENS could be effective in pain reduction among adolescentswho suffered from primary dysmenorrhea.</p> ER -
