Short Summary
TENS (Transcutaneous Electrical Nerve Stimulation) has been consistently shown to be a safe, non-drug option for managing menstrual pain. Multiple randomized trials, systematic reviews, and real-world studies—conducted both internationally and in Japan—report that TENS significantly reduces menstrual cramps and improves quality of life without notable side effects. It can be used alone or with medications like NSAIDs, and is especially helpful for individuals seeking natural or complementary approaches to period pain relief.
Detailed Clinical Summary
Transcutaneous Electrical Nerve Stimulation (TENS) has been thoroughly studied as a non-pharmacological treatment for primary dysmenorrhea. Across randomized controlled trials (RCTs), systematic reviews, and cohort studies, the results overwhelmingly support the efficacy and safety of TENS for menstrual pain management. Below is a categorized clinical evidence summary:
Global Studies – Highlights
| Key Findings | Sources |
| TENS is as effective as or faster than NSAIDs like ibuprofen and naproxen | Dawood et al., Milsom, Coco |
| High-frequency TENS is especially effective | Cochrane Review 2002, Wang et al. |
| Portable, self-applied TENS devices improve pain and quality of life | Lauretti 2015, Mira et al. |
| TENS shows immediate pain relief, reduces uterine activity without side effects | Wang, Milsom, Bai |
| Combined with NSAIDs, TENS offers the best pain control outcome | Dawood et al. |
| TENS has fewer side effects and can reduce opioid use post-procedure | Platon 2020 |
| Health economic analysis suggests TENS is cost-effective for PD management | Rodrigues 2021 |
Japanese Studies – Highlights
| Key Findings | Sources |
| TENS significantly reduced menstrual pain and reduced or eliminated the need for painkillers in many patients | Satoko Higashio 1999 |
| Effective without adverse effects, and may reduce mental distress as well | Itou 2017 |
| Pain relief is dose-dependent; above-threshold stimulation recommended for best results | Kawasaki & Nakagawa, Hyogo University |
