Brief Summary:
Stress urinary incontinence (SUI) is a condition that affects both men and women. SUI is the involuntary leakage of urine caused by an increase in intra-abdominal pressure from activities such as exercise, coughing, laughing, or sneezing. It can significantly affect quality of life as patients avoid activities or behaviors that cause leakage. This clinical trial will compare the efficacy of the Emsella chair to sham and determine if electromagnetic technology is effective in the treatment of SUI.

Condition or disease Intervention/treatment Phase
Stress Urinary Incontinence Device: BTL Emsella Device: Sham BTL Emsella Not Applicable

Detailed Description:

This is a prospective, sham-controlled, observational study of subjects undergoing electromagnetic perineal stimulation for the treatment of SUI. Eligible subjects will be randomized to receive active treatment or sham in a 1:1 ratio. Eight treatments (2 treatments each week) for 4 weeks will be completed with the Emsella chair to the pelvic floor muscles.

Electromagnetic stimulation of the pelvic floor is a FDA approved therapy whereby a coil generates pulsed electromagnetic fields that penetrate deep into the pelvic floor muscles inducing stimulation and providing rehabilitation of weak pelvic 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.This technology is typically not covered by insurance, is minimally invasive, and safe, but has limited data available.

Currently, there is no data available from sham controlled studies evaluating efficacy of this technology. The purpose of this study is to compare the Emsella Chair to sham and to determine whether electromagnetic technology is effective in the treatment of SUI.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 110 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Subjects will be randomized 1:1 to receive active Emsella chair treatments or sham treatments. Study will be performed in a double-blind manner.(Participant, provider, and RNC)
Masking: Triple (Participant, Care Provider, Investigator)
Masking Description:

Randomization will be performed using a table of random numbers. A unblinded RNC will be responsible for maintaining the enrollment and randomization log. The primary RNC will not be in the room when the treatment is being delivered to maintain the blind. Randomization envelopes will be provided by the study's biostatistician and will be securely stored in a locked cabinet.

At minimum two RNCs will solely be responsible for opening the randomization envelopes and delivering the study treatments, according to the group assignment. Ultimately, they will be responsible for maintaining the confidentiality and security of the randomization envelopes.

After the participant is randomized, the RNC will complete the Subject Enrollment and Randomization Log. The log may be stored in the locked cabinet with the envelopes. At the completion of the study the log will be stored in the regulatory binder. The biostatistician will prepare more envelopes, if necessary.

Arm Intervention/treatment
Active Comparator: Emsella Chair Active Treatment
Active treatment subjects will be asked to sit on the center of the Emsella chair. The height of the chair will be adjusted until the participant's feet are on the floor. 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 then be decreased slightly and stay unchanged for the remainder of the treatment time. The treatment threshold should be increased with every treatment until the subject reaches 100%.
Device: BTL Emsella
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. The treatment paradigm consists of 3 different phases. The phases consist of an intense stimulation of the pelvic floor muscles (PFM), which consists of stimlulation and relaxation. The repetition of the phases and focused electromagnetic energy delivery leads to pelvic floor stimulation, adaptation, and remodelation.

Sham Comparator: Emsella Sham Treatment
Sham subjects will be positioned on the device in the same manner as the active treatment group. The sham treatment will be provide some sensation without active HIFEM technology. The programming for the sham treatment will have an amplitude limitation, with the setting below therapeutic level (<10% power).
Device: Sham BTL Emsella
Sham subjects will be positioned on the device in the same manner as the active treatment group. The sham treatment will be provide some sensation without active HIFEM technology. The programming for the sham treatment will have an amplitude limitation, with the setting below therapeutic level (<10% power).




Primary Outcome Measures :
  1. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence. [ Time Frame: 4 weeks after completing all treatments ]
    The primary objective of this study is to compare the efficacy of Emsella Chair to sham by evaluating the the responder rate, where a patient is called a responder if there is ≥ 50% reduction from baseline in the number stress incontinence events.


Secondary Outcome Measures :
  1. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence in relation to the change in total number of subject-reported stress urinary incontinence (SUI) episodes. [ Time Frame: 8 weeks after completing all treatments ]
    Change in the total number of subject-reported stress incontinence (SUI) episodes over 3 days based on voiding diaries. Patients will be giving a 3-day void diary to complete.

  2. The efficacy of the Emsella chair versus sham to treat SUI in relation to the change in subject-reported impression of SUI severity. [ Time Frame: 8 weeks after completing all treatments ]
    Change in subject-reported impression of SUI 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. The available options are normal, mild, moderate, or severe.

  3. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence in relation to the change in subject-reported impression of SUI improvement as measured by the Patient Global Impression of Improvement scale (PGI-I). [ Time Frame: 8 weeks after completing all treatments ]
    Change in subject-reported impression of SUI improvement as measured by the Patient Global Impression of Improvement scale (PGI-I). The subject will select one of the following options, (very much better, much better, a little better, no change, a little worse, much worse, very much worse) to describe their urinary tract symptoms now versus prior to study treatment.

  4. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence related to the change in subject-reported urogenital distress. [ Time Frame: 8 weeks after completing all treatments ]
    Change in subject-reported urogenital distress as measured by the Urinary Distress Inventory questionnaire (UDI-6). The UDI-6 is a six point questionnaire, each question answered is scored as follows; 0 = no, 1 = not at all, 2 = somewhat, 3 = moderately, 4 = quite a bit. Add all scores and divide by 6, then multiply by 25 to calculate the raw score. Higher scores = higher disability.

  5. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence in relation to the change in subject-reported impact of SUI on daily life. [ Time Frame: 8 weeks after completing all treatments ]
    Change in subject-reported impact of SUI on daily life as measured by the Incontinence Impact Questionnaire (IIQ-7) Short Form. The IIQ-7, assesses how their problem effects activities, relationships, and feelings. It is a 7 point questionnaire. Each answer is scored on the following scale 0 = not at all, 1 = slightly, 2 = moderately, 3 = greatly. The higher the score the more effected they are by their condition.

  6. The efficacy of the Emsella chair versus sham to treat stress urinary incontinence in relation to the change in subject-reported impact of urinary incontinence on daily life measured by the Incontinence Quality of Life questionnaire (I-QOL). [ Time Frame: 8 weeks after completing all treatments ]
    Change in subject-reported impact of urinary incontinence on daily life as measured by the Incontinence Quality of Life questionnaire (I-QOL). The I-QOL is a quality of life measure specific to persons with urinary incontinence. The survey consists of 22 incontinent-specific quality of life items all having the following five-point ordinal response; 1 = extremely, 2 = quite a bit, 3 = moderately, 4 = a little, 5 = not at all. The summed total score is transformed to a 0-100 scale ranging from 0 (poor quality of life) to 100 (maximum quality of life).
