EmSella and Pelvic Floor Treatment: A Complete Patient Guide

Pelvic floor weakness affects a significant proportion of adults in the UK, most often presenting as urinary leakage during physical activity, an urgent need to reach a bathroom, or both. Despite being common, many people manage these symptoms quietly for years before seeking help. This guide explains what is happening physiologically when the pelvic floor weakens, how BTL EmSella uses high-intensity electromagnetic energy to address it, what the published evidence shows, and what to expect if you choose to pursue treatment at The London Road Clinic.

Understanding the pelvic floor

The pelvic floor is a group of muscles, ligaments and connective tissue that forms the base of the pelvis. These structures support the bladder, bowel and, in women, the uterus. They also contribute directly to urinary and bowel continence: when you cough, sneeze, lift or jump, the pelvic floor contracts reflexively to prevent leakage. During urination, controlled relaxation of these muscles allows the process to begin.

In addition to continence, the pelvic floor plays a role in sexual function. Tone and responsiveness in these muscles affect sensation, orgasm and, in some patients, pelvic pain. This is why pelvic floor treatment is sometimes discussed in the context of intimate wellbeing alongside continence.

The muscles of the pelvic floor are skeletal muscles, meaning they can be trained and strengthened in the same way as other muscles in the body. They can also weaken, and when they do, the consequences are functional.

Why the pelvic floor weakens

Pelvic floor weakness is not a single-cause condition. Several factors contribute, often acting together.

Pregnancy and childbirth. The pelvic floor bears significant load during pregnancy, and vaginal delivery in particular can stretch or partially disrupt the muscle fibres and the nerves that control them. The effect is not always immediate, though for many women it becomes more noticeable in the years following delivery.

Hormonal change. Oestrogen plays a role in maintaining the quality and responsiveness of pelvic floor tissue. The reduction in oestrogen around perimenopause and beyond is associated with changes in tissue integrity and, in many women, with increasing symptoms of leakage and urgency.

Inactivity or poor motor recruitment. The pelvic floor can be difficult to activate consciously. Many people believe they are doing pelvic floor exercises correctly when their technique is ineffective. Poorly recruited muscles do not strengthen, regardless of effort. This is one reason conservative management alone has a variable success rate.

Body weight and chronic intra-abdominal pressure. Elevated body weight increases the downward pressure on pelvic floor structures over time. Chronic heavy lifting and persistent coughing (including long-term respiratory conditions) have a similar effect.

How EmSella works

BTL EmSella uses High-Intensity Focused Electromagnetic technology, commonly referred to as HIFEM. The treatment is delivered via a purpose-built chair: you sit fully clothed on the seat while the device generates a focused, rapidly oscillating electromagnetic field beneath you.

This electromagnetic field induces a phenomenon called supramaximal muscle contraction. Under normal voluntary effort, a muscle reaches a maximal contraction and cannot meaningfully exceed it. HIFEM bypasses the voluntary neuromuscular pathway entirely, driving the pelvic floor into contractions that are stronger and more complete than anything achievable through conscious effort. Thousands of these contractions occur within a single 28-minute session.

The physiological response to this pattern of deep, repeated contraction is the same as the response to progressive resistance training in other muscle groups. Over the course of a treatment programme, the pelvic floor undergoes neuromuscular re-education, the muscle fibres strengthen and the reflexive response to sudden intra-abdominal pressure becomes more coordinated. The result, in patients who respond well, is reduced or resolved leakage and improved pelvic tone.

Because the electromagnetic field passes through clothing and does not require any intimate contact, the treatment is entirely non-invasive. There is no need to undress.

What the research shows

BTL EmSella has a published evidence base across multiple peer-reviewed journals, including the International Urogynecology Journal. Studies consistently show statistically significant improvements in symptom scores and objective measures such as pad weight tests in patients with stress, urge and mixed urinary incontinence.

The strongest evidence is for stress urinary incontinence, the type associated with leakage during physical activity. Evidence for urge and mixed incontinence is also positive across multiple published studies, though the effect size varies more between individuals.

The evidence has limitations worth acknowledging. A proportion of the published literature is manufacturer-funded, which is typical of early-stage medical device research and does not invalidate the findings, but is worth bearing in mind when interpreting efficacy claims. Independent replication of results is ongoing. The treatment is CE-marked and FDA-cleared.

The honest summary: published research supports meaningful improvement in pelvic floor function and continence symptoms for most patients who complete a standard course. It does not work equally for everyone, and it is not a substitute for pelvic floor physiotherapy where structural or complex neuromuscular issues are the underlying cause.

Who EmSella is most often considered for

Pelvic floor treatment with EmSella is most often considered for adults experiencing:

• Stress urinary incontinence: leakage when coughing, sneezing, laughing, jumping or lifting
• Urge incontinence: a sudden, compelling need to urinate that is difficult to defer
• Mixed incontinence: a combination of both
• Post-pregnancy pelvic floor changes that have not resolved with conventional exercise
• Reduced pelvic tone affecting intimate wellbeing
• Perimenopausal or postmenopausal pelvic floor symptoms

It is not appropriate for patients who are pregnant, or who have metal implants or a pacemaker. Full medical screening is carried out at consultation before treatment is agreed.

EmSella is not a treatment for pelvic organ prolapse, which involves descent of pelvic structures and typically requires assessment by a urogynaecologist or pelvic floor physiotherapist. If symptoms suggest prolapse rather than isolated weakness, appropriate referral is the right path. The clinic will discuss this honestly where relevant.

What to expect during a session

Each session takes 28 minutes. You remain fully clothed throughout and sit on the EmSella chair. The chair is positioned to direct the electromagnetic field at the pelvic floor, and as the treatment begins you will feel strong, rhythmic contractions in the pelvic floor muscles. These contractions are involuntary. You cannot prevent or voluntarily override them during the session.

The sensation is unfamiliar and can feel intense, particularly in the first session, but should not be painful. Most patients adjust to the sensation by the second or third session. There is no skin contact, no intimate exposure and no need for any preparation before you arrive.

There is no recovery period. Most patients leave immediately after each session with no restriction on activity. Some notice mild muscular tiredness in the pelvic region afterwards, similar to the feeling after sustained exercise.

A standard course at The London Road Clinic is six sessions over three weeks, delivered as two sessions per week. The protocol is based on the treatment schedule used in the published clinical literature. Results build progressively during and after the course, with many patients noticing change within the first few weeks and the strongest improvement often apparent six to eight weeks after the final session.

Maintenance. Like all muscular training, the results from EmSella are not permanent without ongoing use of the muscles. Most patients are advised to continue pelvic floor exercises following the course and to consider a top-up session or two annually to sustain the benefit.

Managing expectations: what EmSella can and cannot do

EmSella is a muscle-strengthening tool. It works by improving the strength, coordination and reflexive response of the pelvic floor. What it does not do:

• Repair structural damage to the sphincter mechanism that requires surgical correction
• Address pelvic organ prolapse
• Produce results without any contribution from continued pelvic floor engagement after the course
• Work equally well in all patients; individual response varies based on anatomy, severity of weakness and other factors

The patients who get the most from a course are those whose primary issue is muscle weakness or poor motor recruitment rather than structural failure or prolapse. A screening consultation is essential, not only to confirm that contraindications are absent but to assess whether EmSella is actually the right answer for the presenting concern. Where it is not, we say so.

Pricing for EmSella at The London Road Clinic is from £100 per session. A standard course of six sessions is from £600. All prices include VAT.
