Investigation of the Effect of Breathing-based Pelvic Floor Muscle Training on Menstrual Symptoms, Pain and Quality of Life in Women With Primary Dysmenorrhea: A Randomized-Controlled Trial

Primary dysmenorrheic (PD) pain usually begins during adolescence, at menarche or shortly after (6-24 months), and has a clear and predictable temporal pattern. The pain typically radiates to the back and thighs and lasts for 8-72 hours. The pain is most severe on the first and/or second day of menstrual bleeding. Additionally, systemic symptoms such as nausea, vomiting, diarrhea, fatigue, and insomnia often accompany the pain. In secondary dysmenorrhea, it can result from a range of identifiable pathological conditions, including endometriosis, adenomyosis, fibroids, and pelvic inflammatory disease. Other gynecological symptoms such as intermenstrual bleeding and menorrhagia may also accompany it, depending on the underlying condition. Empirical treatment approaches have been reported as appropriate for patients with primary dysmenorrhea based on symptoms and physical examination results. Recent studies have indicated that during diaphragmatic breathing, all the muscles that make up the thoracic and abdominal walls should expand in a cylindrical manner in all directions through synchronized eccentric activity. Thus, a more effective result will occur with the concentric contraction and 360-degree expansion of the diaphragm during inspiration, which raises intra-abdominal pressure .

Within the framework of this information, the aim of this study is to examine the effects of respiration-based physiotherapy approaches on menstrual symptoms, pain, and quality of life in women with PD.
