Dysmenorrhea is defined as painful menstrual cramps of uterine origin, and considered as one of the most common gynecological disorders among females of childbearing age.
Primary dysmenorrhea (PD) typically manifests within 6-12 months following menarche. It is not associated with organic lesions but is primarily attributed to uterine smooth muscle spasms and vasoconstriction, which are induced by elevated prostaglandin levels.
Additionally, the use of transcutaneous tibial nerve stimulation (TTNS), which consists of the stimulation of the posterior tibial nerve in the superomedial region of the ankle, may be a promising treatment option. The hypogastric sympathetic plexus (L4-L5) and the pelvic parasympathetic plexus (S2-S4) have the same medullar level as the posterior tibial nerve (L4-S3). Thus, inhibitory and excitatory impulses that control the function of the pelvic viscera at the level of the spinal cord can be rebalanced with their stimulation.
