NCT05149573

Brief Summary

The purpose of this study is to gather information about the safety and effectiveness of the non-pharmacological (non-drug), non-invasive treatment known as low-frequency pulsed electromagnetic field (PEMF) therapy. The study team will distribute the PEMF device to female adults with Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) to measure its ability to decrease bladder and pelvic pain as well as other urinary symptoms associated with IC/BPS. There are two sequential Aims in this study and subjects will be recruited to participate in only one Aim. In both Aims, data will be collected at baseline/enrollment, 4-weeks after using PEMF therapy, and 8, 12, and 16 weeks post-enrollment.

Outcome Measures

Primary Outcomes (5)

  • Pelvic pain, as measured by the Brief Pain Inventory (BPI) Short Form

    The BPI Short Form is a validated questionnaire to assess the severity of systemic and pelvic pain and its interference in overall quality of life. Pain severity is measured through four 11-point numeric rating scales (NRS) assessing pain at its "worst," "least," and "average," within the past week, and pain "right now" (at the time of short form completion), with the composite (mean score) of all four scales indicating overall pelvic pain. Pain interference is measured through 7 scales, with scores ranging from 0 (does not interfere) to 10 (completely interferes), for different daily activities. The composite score for the interference items is used to assess overall pain interference, with higher scores indicating greater symptom severity and a change in 2 points indicating a significant change in pain. The form also consists of 3 pain body maps to identify specific locations of pain, and 2 questions related to the effect of current medications on pain.

Study Arms (3)

4-Week Treatment with no Maintenance Period

ACTIVE COMPARATOR

Treatment will be provided via self-administration of pulsed electromagnetic field (PEMF) therapy using the B. Body (full body mat) and B. Pad (targeted pelvic pad). The participant will lie the B. Body mat on any flat surface and lay on the mat with the smaller B. Pad placed directly over the pelvic area. The PEMF device (attached to the control unit) has been pre-programmed to deliver the same level of energy every time. Participants will be instructed to administer this home treatment twice a day (morning and evening) for 8-minute sessions over a 4-week period. After 4 weeks, participants will return the device and complete one set of electronic questionnaires during the last week of the month for the following 3 months.

Device: Pulsed Electromagnetic Field (PEMF) Device

4-Week Sham Treatment with no Maintenance Period

SHAM COMPARATOR

Participants will be provided with a sham B. Body and B. Pad that appears identical to the active pulsed electromagnetic field (PEMF) device. The participant will lie the sham B. Body mat on any flat surface and lay on the mat with the smaller sham B. Pad placed directly over the pelvic area. The participant will be instructed to administer this sham treatment twice a day (morning and evening) for 8-minute sessions over a 4-week period. After 4 weeks, participants will return the sham device and complete one set of electronic questionnaires during the last week of the month for the following 3 months.

Body mat on any flat surface and lay on the mat with the smaller B. Pad placed directly over the pelvic area. The PEMF device (attached to the control unit) has been pre-programmed to deliver the same level of energy every time. Participants will be instructed to administer this home treatment twice a day (morning and evening) for 8-minute sessions over a 4-week period. After 4 weeks, participants will keep the device and use it for 1 week (7 days) during the last week of the month for the following 3 months. Each participant in this group will be asked to complete a set of electronic questionnaires immediately following their week-long maintenance treatment during the last 3 months of the study.

Device: Pulsed Electromagnetic Field (PEMF) Device

Interventions

BEMER PEMF device consists of a B. Body (full body mat), B. Pad (targeted pelvic pad), and Control Unit which powers the device. Both B. Body and B. Pad must be plugged in simultaneously into the Control Unit and activated individually. B. Body must be placed on a flat surface (e.g. floor, bed, reclining chair, etc) for best results.

Also known as: BEMER PEMF, BEMER B. Body, BEMER B. Pad, BEMER Control Unit
4-Week Treatment with 1-Week-Per-Month Maintenance Period for an Additional 3 Months4-Week Treatment with no Maintenance Period

The sham PEMF device appears identical to the BEMER PEMF device, with all of the same components and accessories, but does not emit a pulsed electromagnetic field.

Intervention Model
SEQUENTIAL
Model Details: This study is designed as a double-blind, sham-controlled clinical trial separated into two Aims. Aim 1 will include 60 female adults with IC/BPS, divided into two groups: 1) 30 participants with an anesthetic bladder capacity (BC) ≤ 400cc and 2) 30 participants with BC \> 400cc. Patients within each of the two groups will be randomly assigned in a 1:1 ratio to either the PEMF (treatment) or Sham (control) group. The Sham device is identical to the treatment device but does not deliver PEMF. All participants will be instructed to use their device every day, morning and evening, for 8-minute sessions over a 4-week period. Aim 2 will include an additional cohort of 15 female adults with IC/BPS. These participants will undergo the standard 4-week regimen of PEMF therapy, followed by a one-week-per-month maintenance period of twice daily PEMF therapy for an additional 3 months post-enrollment (the fourth week in months 2, 3, and 4).
