Effects of High-frequency Deep Diathermy on Heart Rate Variability in Women With Primary Dysmenorrhea

Study Overview
=================
Brief Summary
-----------------
Superficial heat therapy is mainly used to relieve menstrual pain, but it does not penetrate deeper than the skin tissue. In order to penetrate deep into the deep layers and promote tissue relaxation, deep heat therapy can be effective. The treatment time for deep heat treatment is controversial, and there is no study on deep heat treatment using radio frequency for dysmenorrhea. Therefore, in this study, by applying radiofrequency waves at different times to the lower abdomen for patients with primary dysmenorrhea, the pain and changes in the autonomic nervous system were compared with thermotherapy to suggest appropriate therapeutic interventions.
