Intervention / Treatment
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.

Arms and Interventions
Participant Group / 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%.
|
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).
