Chronic Pelvic Pain: Trial Examines Novel Intravaginal Electrical Stimulation Therapy

By M. Jean Uy-Kroh, MD, and Elim Shih, MD

Chronic pelvic pain is a complex diagnosis that encompasses multiple conditions and organ systems. Its treatment is also challenging due to an incomplete understanding of pain processing.

Evidence confirms opioids worsen chronic pelvic pain by lowering pain thresholds and increasing pain sensitiv­ity. Nonpharmacological therapies are the treatment of choice. Physicians should counsel patients on the thera­peutic benefit of restorative sleep and exercise. One novel therapy using intra­vaginal electrical stimulation is currently under investigation at the Women’s Health Institute.

We are actively enrolling subjects in the INSPIRE (INtravaginal Stimulation for Pelvic Pain Improvement and Relief) trial, which is a randomized, controlled trial utilizing a nonimplanted, intravagi­nal electrical stimulation device within the comfort and privacy of the patient’s home.

Study design

The INSPIRE trial is a 12-week research study. We seek women diagnosed with chronic pelvic pain lasting longer than six months. Subjects are randomized into one of two study groups. One study group will use an active device and the other will use a sham device.

The trial requires four visits to Cleveland Clinic’s main campus. After enrollment, subjects must commit to perform home sessions using the device six times per week, 12 minutes per session, for a total of 12 weeks.

If the trial proves the active device sig­nificantly reduces pain, then the active device will be provided to all women in the study at no cost.

Being proactive matters

At Cleveland Clinic, we encourage women to take a more active role in the treatment of their chronic pelvic pain. If proven effective through ongoing research, a novel domiciliary device may be an alternative or adjunct therapy in chronic pelvic pain.
