About this study

Official title: A Single-Blind, Randomized Study of the BTL Emsella Chair Versus Sham for the Treatment of Chronic Pelvic Pain

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BTL Emsella chairDevice

    Subjects will sit on the device. The Research Nurse Coordinator (RNC) will turn the device on and increase the setting gradually until the patient reaches their sensory threshold. This is the maximum sensation the patient can tolerate. The treatment threshold should be increased with every treatment until the subject reaches 100%.

Study groups in NCT04248491
Study groupRoleWhat they receive
Emsella Chair Active TreatmentActive comparatorSubjects will be asked to sit on 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 remainder of the treatment. The treatment threshold should be increased with every treatment until the subject reaches 100%.
Receives: Device: BTL Emsella chair
Emsella Sham TreatmentSham comparatorSham 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 (<10% power).
Receives: Device: BTL Emsella chair

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Change in Subject-reported Pain and Discomfort as Measured by the Visual Analog Scale (VAS)

    Mean change in Pain VAS from baseline to end of treatment will be compared between the Emsella Chair group and the sham group. VAS is scored from 0-10, where 0 = no pain and 10 = worst possible pain. Value at week 8 minus the value at baseline was used to calculate change. Negative numbers indicate an improvement in pain, and positive numbers indicate a worsening pain.

    Measured: Baseline and week 8

Secondary outcomes (14)
  1. The Change in Subject-reported Impression of CPP Severity as Measured by the Patient Global Impression of Severity Scale (PGI-S).

    Change in subject-reported impression of CPP severity as measured by the Patient Global Impression of Severity scale (PGI-S). The subject will check the box that describes how their condition is now. This is a four point scale, with 1=normal, 2= mild, 3=moderate, and 4= severe. The value at week 12 minus the value at baseline was calculated. A positive change indicates a worsening condition, and a negative value indicated an improvement in condition.

    Measured: Baseline and week 12

  2. The Number of Participants Reporting Significant Symptom Improvement as Measured by the Patient Global Impression of Improvement Scale (PGI-I)

    Subject-reported impression of CPP improvement as measured by the Patient Global Impression of Improvement scale (PGI-I). The scale has 7 points with a lower number indicating improvement: (1=very much better, 2=much better, 3=a little better, 4=no change, 5=a little worse, 6-=much worse, 7= very much worse) to describe their chronic pelvic pain symptoms now versus prior to study treatment. We will report the number of individuals reporting a score of 1 or 2, very much better or much better (significantly improved).

    Measured: at 12 weeks

  3. The Change in Subject-reported Impression of CPP Severity as Measured by Subject-reported Pelvic Floor Tenderness to Palpation During 4 Quadrant Pelvic Examination as Measured by VAS.

    A trained provider will complete a pelvic (women) or rectal (men) exam on subjects. The VAS is a validated questionnaire that assesses pain on a scale from 0 = no pain to 10 = worst possible pain. The subject will provide a pain score from 0 - 10 for each of the 4 quadrants assessed. The average pain score of the 4 quadrants is then calculated. The average pain score ranges from 0 to 10. The value from baseline to secondary endpoint at week 12 is calculated. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms.

    Measured: Baseline and week 12

  4. The Change in Subject-reported Impression of CPP Severity in Females.

    The change in CPP severity as measured by subject-reported sexual function as measured by the Female Sexual Function Index questionnaire (FSFI) for female subjects. The FSFI is a 19 question survey. A lower score is equivalent to a higher degree of sexual dysfunction. Scores range from 0 to 36. The change value is calculated from baseline to week 12. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms.

    Measured: Baseline and Week 12

  5. The Change in Subject-reported Impression of CPP Severity in Males.

    The change in CPP severity as measured by subject-reported sexual function as measured by the Brief Sexual Function Inventory questionnaire (BSFI) for male subjects. The BSFI is a validated questionnaire for male sexual function. Average score ranges from 0 to 44. A lower score indicates a higher degree of dysfunction. Positive change indicates improvement of symptoms. A negative change indicates worsening of symptoms. Calculated from the value at week 12 minus value at baseline

    Measured: Baseline and week 12

  6. The Change in Subject-reported Depression Severity as Measured by the Beck Depression Inventory (BDI).

    The Beck Depression Inventory is a 21-question multiple-choice self-report inventory. 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.

    Measured: Baseline and week 12

  7. 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.

    Measured: Baseline and week 12

  8. 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.

    Measured: Baseline and week 12

  9. 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.

    Measured: Baseline and week 12

  10. 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.

    Measured: Baseline and week 12

  11. 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.

    Measured: Baseline and week 12

  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.

    Measured: Week 12

  13. 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.

    Measured: Baseline and week 12

  14. Safety and Tolerability Will be Assessed as the Number of Esmella Chair-related With Adverse Events.

    Safety and tolerability of the Emsella chair compared to Sham will be assessed as the number of adverse events reported that were determined to be related to the Emsella chair treatment.

    Measured: From baseline to week 12
