- How Emy Trainer works, and what the clinical study shows after 3 months of using Emy Trainer.
Why use a device to strengthen your pelvic floor?
The pelvic floor is a discreet but essential group of muscles. It supports the pelvic organs, contributes to continence and helps keep the pelvis stable.

After pregnancy, with age or simply through daily life, it can lose tone. This may show up as urinary leaks, a feeling of weakness or discomfort during sex.
A pelvic floor trainer helps you feel your pelvic floor better and train it in a more targeted way. Many women use one to continue at home the work started in clinic.
What types of pelvic floor devices are there?
There are several types of devices, which work in different ways. The choice is preferably made with your midwife, a physiotherapist or your GP.
Biofeedback trainers
Biofeedback trainers are inserted into the vagina and capture your contractions through sensors. An app shows you in real time whether you are activating your pelvic floor, so you train actively with voluntary contractions. To find out more, read our article on biofeedback devices.

Electrical stimulation devices
Electrical stimulation devices send mild electrical impulses that trigger a muscle contraction without any voluntary effort on your part. This is known as passive rehabilitation. These devices are usually used on the recommendation of a healthcare professional. Find out how pelvic floor electrical stimulation works in our dedicated article.

Kegel balls and vaginal cones
Simpler options such as Kegel balls or vaginal cones work through their weight: you activate your muscles to keep them in place. They are discreet and easy to fit into everyday life.

How do you choose a pelvic floor trainer?
- Medical device status: is it a CE-marked medical device?
- Clinical data: does the manufacturer publish a verifiable clinical study on its own product?
- Support: does the accompanying app offer guided exercises and progress tracking?
- Ergonomics: does the device suit your anatomy and your level?
How does Emy Trainer work?
Emy Trainer is a connected pelvic floor trainer using biofeedback and a CE-marked medical device. Once you have switched it on and connected it to the Emy app on your smartphone, you insert it. Through small games, such as steering a hot-air balloon or virtual fishing, you learn to contract your pelvic floor and then relax it.
The exercises are varied: fast, held or repeated contractions. The app shows your progress and also offers content on yoga, gentle exercise and the pelvic floor. Emy Trainer is rechargeable, designed for long-term use, designed in France and made in Europe.

A clinical study carried out at Strasbourg University Hospital assessed Emy Trainer with more than 50 patients experiencing stress urinary incontinence. After 3 months of using Emy Trainer, 98% of participants reported an improvement in their quality of life, and 91% an improvement in their urinary symptoms (Jochum et al., 2021).

How often should you train with a device?
Starting gently is often a good approach. A session lasts 5 to 20 minutes; train several times a week. The idea is to build a habit, not a chore.
After a few weeks, you can adjust your training to your needs. For clear changes, allow two to three months of regular training.

What precautions should you take?
Pelvic floor devices are for personal use. Clean your device carefully after each use, use a water-based lubricant if needed, and always insert it gently, without forcing. If discomfort persists, stop and talk to a healthcare professional. Emy Trainer must not be used during pregnancy.
Can you use a device after giving birth?
Yes, a device can support your postnatal pelvic floor rehabilitation. Emy Trainer can be used from 7 weeks after giving birth at the earliest, once your doctor or midwife has given the go-ahead. Your midwife can check with you that you are ready and show you suitable rehabilitation exercises.
Many women use a device alongside the rehabilitation sessions prescribed after birth, to continue at home the work started in clinic.
