This study established normative data for pudendal and perineal nerve function in women, finding that age and vaginal delivery history impact results. These findings help define normal limits for these important nerve tests.

Area of Science:

  • Neuroscience
  • Urogynecology
  • Clinical Electrophysiology

Background:

  • Pudendal and perineal nerve function is crucial for pelvic floor health.
  • Establishing normative data is essential for interpreting electrophysiological tests.

Purpose of the Study:

  • To create normative distribution data for pudendal and perineal nerve compound muscle action potentials.
  • To analyze these data in healthy women across a broad age range and with varied vaginal delivery histories.

Main Methods:

  • 42 continent women aged 20-67 years were studied.
  • A transvaginal approach stimulated the pudendal nerve at the ischial spine.
  • Surface electrodes measured external anal sphincter responses and proximal urethral responses.

Main Results:

  • Data were not normally distributed, requiring transformations for normalization.
  • Advancing age and a history of vaginal delivery showed clinical correlations with nerve potential measurements.

Conclusions:

  • This data collection enables the definition of normal limits for these nerve tests.
  • It initiates the study of how clinical variables affect test outcomes and patient results.
