A 20-year-old nulligravid woman presents with severe pain during menstruation.

TENS has been shown to be effective for managing primary dysmenorrhea when pharmacological options are contraindicated or refused. It works by interfering with pain signal transmission and increasing endorphin levels.

Toronto Notes 2023 – Gynecology, Dysmenorrhea:

“High-frequency TENS is effective in managing primary dysmenorrhea and can be considered when NSAIDs or hormonal therapies are not acceptable to the patient.”

MCCQE1 Objectives – Gynecology > Menstrual Disorders:

“Candidates must be aware of non-pharmacological interventions for dysmenorrhea, including TENS and heat therapy.”

Options D and E involve hormonal or surgical intervention. Spinal manipulation and massage (B and C) lack consistent evidence for dysmenorrhea relief.
