  Purpose
Obturator externus (OE) muscle has the possibility as a pain generator, considering its anatomical and functional aspects, but this muscle as a possible target for therapeutic intervention is currently understudied in pain practice.

Condition
Chronic Pelvic Pain

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective

Primary Outcome Measures:
  • Post-injection pain score [ Time Frame: at 2 weeks after injection ]
    Before and after the OE muscle injection, patients were asked to rate their pain score using a 10-point numeric rating scale (NRS; 0=no pain, 10=worst possible pain). We also assessed the degree of patient satisfaction as excellent, good, fair, and bad during 2 weeks after injection. In this period, any analgesic medications did not change in all patients. Complications associated with OE muscle injection were investigated.
