BTL Emsella Chair Versus Sham for the Treatment of Overactive Bladder
Purpose
The purpose of this clinical trial is to compare the Emsella Chair therapy to Sham and to determine whether electromagnetic technology is effective in the treatment of overactive bladder (OAB). Currently there are no other studies utilizing the Emsella Chair for the treatment of OAB. Eligible subjects will receive 2 treatments per week for a total of 4 weeks.

For Females Only: 8. If of child-bearing age and female, agree to practice approved birth-control methods (oral contraceptives, condom barrier, injection, diaphragm or cervical cap, vaginal contraceptive ring, IUD, implantable contraceptive, surgical sterilization (bilateral tubal ligation), vasectomized partner(s))
Exclusion Criteria
- Botox® use in bladder or pelvic floor muscles in the past year 2. Subject weighs greater than 330 pounds 3. Pulmonary insufficiency, defined as difficulty breathing and fatigue, especially during exercise; chest pain, such as squeezing, pressure of tightness; the sensation of rapid or irregular heartbeat (palpitations); swelling of the legs or feet; dizziness or fainting; and/or bluish discoloration of the nails and/or lips (cyanosis) 4. Any condition that causes a lack of normal skin sensation to the pelvis, buttocks, and thighs, at the discretion of the investigator. 5. Major metal implants such as: metal plates, screws, joint replacements, implanted cardiac pacemakers, drug pumps, neurostimulators, electronic implants, copper intrauterine devices, defibrillators, and metal implants in the pelvic area. Patients with other metal implants will be evaluated by the investigator for inclusion in the study. 6. Subject has a piercing between the waist and knees and is not willing to remove it before each treatment 7. Active urethral diverticula 8. Known vesicoureteral reflux 9. Currently healing from surgical procedures where muscle contraction may disrupt the healing process 10. Subject is currently receiving treatment for a malignant tumor that would interfere with study participation. Skin cancers are permitted. 11. Subject has used the BTL EMSELLA device previously 12. Subject has urinary incontinence of neurogenic etiology, such as multiple sclerosis, spina bifida, Parkinson's, spinal cord injury, diabetic neuropathy, neurogenic bladder etc. 13. Current urinary tract infection. If a subject has a confirmed symptomatic UTI at screening, per investigator's clinical judgment, they will be deferred from screening until treatment is completed, and may resume once symptoms have resolved 14. Current use of neuromodulation therapy, including interstim and PTNS, for bladder symptoms within 3 months of screening visit (if past sacral/pudendal implant, must be explanted) 15. Currently participating in an investigational study that may impact study results or previously received an investigational drug or treatment within 30 days of the Screening Visit 16. Current or history of any physical condition that, in the investigator's opinion, might put the subject at risk or interfere with study results interpretation For Females Only: 17. Pregnant, or planning to become pregnant, at screening or anytime throughout the study period - Note: For the sake of preserving scientific integrity, one or more of the eligibility criteria have been left off the list posted while the trial is ongoing. A full list of eligibility criteria will be posted upon completion of the trial.

- Intervention Model Description
- Patients who meet all eligibility criteria will be enrolled in the study and randomized (1:1) to receive Emsella chair or sham treatments. The subject and biostatistician will be blinded to the group allocation throughout the study. The initial analysis of data, performed by the biostatistician will not include group assignment.

- Double (Participant, Outcomes Assessor)
- Masking Description
- The sham Emsella treatment will provide sensation without active HIFEM technology. The sham treatment amplitude setting will be limited to below the therapeutic level.
Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Active Comparator Emsella Chair Active Treatment |
Active subjects will be asked to sit on the center of the device and the height will be adjusted until the subject's feet are on the floor. The active treatments are individualized, since some subjects will be more sensitive than others. The Emsella chair will be turned on and the setting gradually increased to the subject's sensory threshold; the maximum sensation the subject can tolerate. The setting will be decreased slightly and stay unchanged for the reminder of the treatment. The treatment threshold should be increased with every treatment until the subject reaches 100%. |
|
|
Placebo Comparator Emsella Chair Sham Treatment |
Sham treatment subjects will be positioned on the device in the same manner. The sham treatment will provide some sensation without active HIFEM technology. The programming for the sham treatment will have an amplitude limitation, with the setting below the therapeutic level (less than 10% power). |

Detailed Description
Overactive bladder (OAB) is a common and often debilitating condition in both men and women. OAB symptoms including urinary frequency, urgency, and/or urge incontinence (UI), have been found to negatively impact quality of life. Due to side effects and the lack of patient compliance to pharmacologic treatments for OAB, non-pharmacologic treatments are in high demand for this condition. Neuromodulation therapies have become increasingly popular for the treatment of overactive bladder in men and women. These neuromodulation therapies work in treating OAB by stimulating the pudendal nerve. The BTL EmsellaTM (Emsella Chair) is a conservative neuromodulation therapy that may have a role for patients who are not surgical candidates or who desire a noninvasive treatment option. The ideal treatment for OAB is still lacking. Many patients are interested in pursuing conservative treatment options. The Emsella chair may have a role for patient who do not desire surgery found with SNM or desire a noninvasive treatment option. The Emsella chair is approved as a treatment for stress urinary incontinence (SUI). Overactive bladder patients may benefit from treatment. The Emsella chair generates electromagnetic stimulation which is able to penetrate deep into the pelvic floor muscles inducing stimulation and providing rehabilitation for weak pelvic floor muscles. The Emsella chair is a novel high-intensity focused electromagnetic (HIFEM) technology for the treatment of SUI, in addition to other pelvic floor related disorders. HIFEM technology induces deep pelvic floor muscle contractions designed to deliver the equivalent of 11,200 Kegel exercises over 28 minutes.
