Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To determine the feasibility, safety, and function of intravaginal electrical stimulation (IVES), participants will be asked to use the device in 3-minute stimulation increments over a single 20-30-minute session with the stimulation device. During this session, participants will be administered IVES by a pelvic floor physiotherapist using a physiotherapist recommended protocol with a stimulation device restricted to a frequency range of 2-100Hz, current amplitude of 0-90mA, pulse width between 50µs-450µs, controllable duty cycle, controllable ramp up time, and a biphasic wave output. The precise protocol used will depend on the ability of the impulse to produce a valuable contraction. This will help correlate contraction strength with frequency. During administration of the IVES, the protocol, pelvic floor muscle contraction strength, pain/discomfort, and any adverse events will be recorded.
