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 chronic pelvic pain. Currently there are no other studies utilizing the Emsella Chair for the treatment of chronic pelvic pain. Eligible subjects will receive 2 treatments per week for a total of 4 weeks.


Chronic pelvic pain (CPP) is a common and often debilitating in both men and women. It occurs below the umbilicus and is severe enough to cause functional impairment or require treatment. The health care burden of CPP is substantial. First line treatments involve a multidisciplinary approach and include general relaxation and stress management, patient education, self-care and behavioral modification, and pain management. Second-line agents include physical therapy (avoiding kegel exercises), and oral and intravesical agents. More invasive options including neuromodulation.

The Emsella chair is currently approved as a treatment for stress urinary incontinence. Chronic pelvic pain 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 discorders. HIFEM technology induces deep pelvic floor muscle contractions designed to deliver the equivalent of 11,200 Kegel exercises over 28 minutes.

Pelvic floor trigger point injections, pudendal nerve block, or bladder hydrodistention within 30 days prior to screening
Subject weighs more than 330 pounds
Current UTI. If a subject has a confirmed symptomatic UTI at screening, per the investigator's clinical judgment, they will be deferred from screening until treatment is completed, and may resume once symptoms have resolved

Patients with other metal implants will be evaluated by the investigator for inclusion in the study
Subject has a piercing between the waist and knees and is not willing to remove it before each treatment
Subject has used the BTL EMSELLA device previously
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
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
\. Pregnant, or planning to become pregnant, at screening or anytime
throughout the study period
