Electrophysiological study (EPS) is a diagnostic procedure used to evaluate the electrical activity of tissues and organs. In the context of gynecology, EPS can be particularly valuable in assessing the function of the pelvic floor muscles, nerves, and related structures. This type of study often involves the use of specialized equipment to measure the electrical impulses generated by these tissues, providing insights into conditions like pelvic floor dysfunction, urinary incontinence, and chronic pelvic pain.
