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 stress urinary incontinence (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.

It is composed of items relating to symptoms of depression such as hopelessness, irritability, guilt, fatigue, weight loss, and lack of interest in sex. Subjects that score greater than 30 at any time may be referred for psychological evaluation but may continue study participation. A higher score indicates a greater severity of depression. Scores can range from 0 to 63. The value of change calculated from baseline minus week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Change in Subject-reported Bother Related to Overactive Bladder Symptoms as Measured by the Overactive Bladder Questionnaire-Short Form (OAB-Q). | Since both overactive bladder (OAB) and interstitial cystitis/bladder pain syndrome (IC/BPS) share urinary urgency and frequency symptoms, this validated measure will evaluate additional aspects associated with OAB and IC/BPS. The OAB-Q Short Form (SF) consists of two scales assessing symptom bother and health-related quality of life (HR-QOL) in patients with OAB. Each question is rated on a 6 point scale with 1 = Not at all and 6 = A very great deal. Scores can range from 0 to 100. The change value is calculated from the baseline value minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Change in Subject-reported Urinary and Pain Symptoms, as Well as Bother, as Measured by the Interstitial Cystitis Symptom Index and Problem Index (ICSI-PI). | IC/BPS patients can share urinary urgency and frequency symptoms. The ICSI-PI measures urinary and pain symptoms and assesses how problematic are. A higher score indicates greater severity of symptoms. Scores range from 0-36. The change is calculated by the baseline value minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Change in Subject-reported Anxiety Symptoms as Measured by the Generalized Anxiety Disorder Questionnaire (GAD-7). | The GAD-7 questionnaire is a 7-item validated scale to assess generalized anxiety disorder. Patients are grouped by GAD score 0-7 and 8+ which suggests no anxiety disorder and probably anxiety disorder, respectively. Scores can range from 0 to 21. The change is calculated as the value at baseline minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Change in Subject-reported Pain as Measured by the McGill Pain Questionnaire (MPQ). | The McGill Pain Questionnaire can be used to evaluate a person experiencing pain over time to determine the effectiveness of an intervention. The questionnaire consists of 22 questions. Each question is scored 0 (none) to 10 (worst possible). A higher score indicates more severe pain symptoms. Scores range from 0 to 220. The change calculated from the value at baseline minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Change in Subject-reported Rumination, Magnification, and Helplessness Related to Pain as Measured by the Pain Catastrophizing Scale (PCS). | The Pain Catastrophizing Scale (PCS) lists thirteen statements describing different thoughts and feelings that may be associated with pain. Each statement is rated as: 0 =not at all, 1= to a slight degree, 2= to a moderate degree, 3= to a great degree, and 4= all the time. Subjects who report a larger number associated with such thoughts during pain are more likely to rate the pain as more intense. Scores range from 0 to 52. The change is calculated as the value at baseline minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
| The Subject-reported Perception of Overall Improvement in Pain as Measured by Global Response Assessments (GRA) for Pain and Quality of Life. | The GRA is a 7-point scale to evaluate the subject's perception of overall improvement in pain. It is scored as follows: 1 = markedly worse, 2 = moderately worse, 3 = mildly worse, 4 = same (unchanged), 5 = slightly improved, 6 = moderately improved, and 7 = markedly improved. The number of participants reporting significant improvement in pain (score of 6 or 7) at week 12 are counted. | Week 12 |
| Change in Subject-reported Pain and Discomfort as Measured by VAS | Change in subject reported pain and discomfort as measured by the Visual Analog Scale (VAS). The VAS is a validated questionnaire that assesses pain on a scale from 0= no pain to 10= worst possible pain. The change is calculated from the value at baseline minus the value at week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. | Baseline and week 12 |
