The Emsella chair uses focused electromagnetic energy to trigger thousands of pelvic floor muscle contractions while you sit fully clothed. A single 28-minute session delivers the equivalent of roughly 11,200 Kegel exercises, contractions far more intense than anything you could produce on your own. The technology is FDA-cleared for treating urinary incontinence in both men and women, and it requires no surgery, no probes, and no downtime.
How Electromagnetic Energy Triggers Muscle Contractions
The chair contains an electromagnetic coil built into the seat. When activated, it generates a high-intensity focused electromagnetic field (HIFEM) that passes through your clothing and skin to reach the motor neurons in your pelvic floor. These neurons control the muscles responsible for bladder support and continence.
The electromagnetic field depolarizes the membranes of those motor neurons, which is the same electrical event that happens when your brain sends a signal to contract a muscle. But there’s a key difference: the chair fires these signals at a repetition rate so high that your pelvic floor muscles reach what’s called “supramaximal” contractions. These are involuntary contractions stronger than anything you could achieve through conscious effort. Your brain simply can’t recruit that many muscle fibers that quickly on its own, which is why manual Kegel exercises, even done perfectly, can’t match the intensity.
The treatment cycles through phases of stimulation and relaxation. It contracts the muscles, holds them, then releases, then repeats. This pattern forces the pelvic floor to adapt over time, rebuilding strength and restoring the neuromuscular control that keeps the bladder sealed during coughing, sneezing, laughing, or sudden movement.
What a Treatment Session Feels Like
You sit on the chair in your regular clothes. There’s no undressing, no insertion of any device, and no preparation. When the machine turns on, you’ll feel rapid, intense contractions in your pelvic floor. Most people describe the sensation as a strong tingling or pulling. It feels unusual, especially during the first session, but it isn’t painful. The intensity is typically adjusted gradually so you can get used to the sensation before it reaches full power.
Sessions last 28 minutes. When it’s over, you stand up and go about your day. There’s no recovery period, no soreness that limits activity, and no restrictions on exercise or work afterward.
Standard Treatment Schedule
The typical protocol is six sessions total: two per week for three weeks. Some people notice improvement after the first few sessions, but the full benefit builds over the course of the entire series as the pelvic floor muscles progressively strengthen and the neural pathways governing bladder control are retrained.
Results generally last six to twelve months, depending on individual factors like age, severity of incontinence, and overall muscle health. After that window, a maintenance round of sessions can restore the effects. Think of it like any other muscle conditioning: the gains are real, but they fade without ongoing work. The chair essentially does that ongoing work for you on a periodic basis.
How Effective Is It?
A comparative study published in a peer-reviewed pelvic medicine journal found that 55% of Emsella patients achieved normalized bladder function, compared to 72% of patients who underwent surgical repair. Surgery also had lower one-year recurrence rates (14% versus 31% for Emsella). So surgical correction remains more effective for severe cases, particularly those involving pelvic organ prolapse.
Where Emsella stands out is recovery. In the same study, 91% of Emsella patients resumed daily activities within a week, while surgical patients faced significantly longer downtime. For people with mild to moderate urinary incontinence who want to avoid surgery, that tradeoff matters. The chair won’t replace a surgical fix for advanced prolapse, but it offers a meaningful improvement for many people with fewer disruptions to daily life.
Beyond Incontinence: Pelvic Floor and Sexual Health
Because the pelvic floor muscles play a role in sexual function for both men and women, strengthening them can have secondary benefits. The same muscles that support bladder control also contribute to arousal, sensation, and orgasm. Clinical trials are currently investigating the chair’s effects on male sexual dysfunction specifically, based on the rationale that pelvic floor therapy has already shown improvement in sexual function through other methods. The overlap in anatomy and physiology between continence and sexual health is significant enough that researchers expect similar benefits from electromagnetic stimulation.
These sexual health benefits aren’t yet part of the device’s formal FDA clearance, which covers urinary incontinence only. But many clinics market the treatment for both purposes, and the physiological logic is straightforward: stronger pelvic floor muscles improve function across everything those muscles do.
Who Can and Can’t Use It
The chair is cleared for use in both men and women with urinary incontinence. It’s noninvasive enough that most people are candidates. However, there are firm contraindications. You cannot use the Emsella chair if you have metal implants in the pelvic area, a pacemaker or other implanted electronic device, or if you are pregnant. Anyone who has had a recent surgical procedure in the treatment area should also wait. The electromagnetic field is powerful enough to interfere with metal and electronic devices, making these exclusions non-negotiable rather than precautionary.
Copper IUDs are a common question. Because they contain metal positioned directly in the treatment zone, most providers will advise against treatment or require removal first. If you have any implanted device, clarifying its material composition with your provider before booking is essential.
How It Compares to Kegel Exercises
Kegel exercises work the same muscles through voluntary contraction. Done consistently and correctly, they can improve mild incontinence over weeks or months. The problem is execution: studies consistently show that a large percentage of people perform Kegels incorrectly, often engaging the wrong muscles entirely. Even when done right, voluntary contractions can only recruit a fraction of the available muscle fibers.
The Emsella chair bypasses both problems. The electromagnetic field activates the correct muscles automatically, and it drives them to contraction intensities you can’t reach voluntarily. For someone who has tried Kegels without success, or who lacks the pelvic floor awareness to perform them correctly, the chair offers a way to achieve the same type of strengthening at a much higher intensity and with guaranteed muscle targeting.
