Do Kegel exercises but aren’t sure whether the correct muscles are actually working? Pelvic floor muscle training is effective only if you truly activate the target muscles — and not your abdomen or thighs instead. The evoStim E's EMG-biofeedback system measures the muscles' electrical activity and shows in real time whether you are performing the exercises correctly. The ETS function even "assists" your voluntary contraction — a more targeted training than any method alone. Why evoStim E? EMG-biofeedback – your muscles "talk" The EMG sensor detects the electrical activity of muscle fibers — that is, it measures directly (not indirectly via pressure) whether the pelvic floor muscles are active. You get precise feedback on whether the exercise is truly effective. ETS – the stimulator assists ETS (Electrically Triggered Stimulation) senses when you contract your muscles and, if the activity reaches a set threshold, provides electrical impulses to "assist" the contraction. Your effort and the stimulator's effect add together. 5 program groups – targeted therapy Stress, urge, mixed incontinence, pain and relaxation — each has 9 predefined, customizable programs. The Intellistim feature allows on-the-fly fine-tuning of stimulation frequency. Touchscreen + rotary knob Real-time EMG feedback is displayed on the touchscreen. The rotary knob enables precise, quick intensity adjustments — treatment control is simple and convenient. Who is it recommended for? Stress urinary incontinence – leaking when coughing or sneezing Caused by sphincter weakness: urine leakage with physical strain (coughing, laughing, lifting). evoStim E programs at 35–100 Hz target phasic muscle fibers, while EMG-biofeedback shows whether the pelvic floor muscles are truly activated. This is the most common form of incontinence and often responds well to muscle training. Urge (overactive bladder) incontinence – sudden, strong urge Caused by bladder muscle hyperactivity: a sudden, overwhelming need to urinate. evoStim E programs at 5–20 Hz aim to calm the bladder muscle, reducing involuntary contractions. Pulse width is adjustable between 250–400 µs to suit patient comfort. Mixed incontinence – both types together If stress and urgency incontinence occur together, evoStim E's mixed program addresses both phases: first bladder calming (low frequency), then muscle training (high frequency). It can also be treated with a personalized program or by applying the two program types consecutively. Fecal incontinence – anal probe treatment For weakness of the anal sphincter, using evoStim E with an anal probe (PeriProbe Analis or PeriSphera A) enables targeted sphincter training. EMG-biofeedback precisely measures anal sphincter activity here as well. Detailed guide on fecal incontinence → Postpartum rehabilitation Childbirth can damage or overstretch the pelvic floor muscles. evoStim E can aid targeted muscle recovery — EMG-biofeedback objectively measures activation and progress. Treatment may begin after the 6–8 week postpartum medical check-up. How to use the evoStim E? 1 Select the program On the touchscreen choose the program group that matches your type of incontinence (stress, urgency, mixed, pain or relaxation). Any of the 5 quick-access buttons can be assigned one of the 9 programs. 2 Connect the probe and cables The device has two channels: the EMG sensor (input) and the stimulation (output) cable. Connect both to the probe. Moisten the probe with water or lubricant gel, then insert it. 3 Set intensity and EMG threshold Use the rotary knob to set the stimulation intensity (pleasant but producing a definite muscle contraction). In ETS mode set the EMG threshold — this determines what strength of voluntary contraction triggers the assisting stimulation. 4 Exercise with EMG-biofeedback The screen shows the EMG waveform in real time — your muscle activity. In ETS mode, if your contraction reaches the threshold, the device delivers assisting impulses. Contract your muscles when prompted — your effort and the stimulator combine. 5 Track your progress EMG values can be compared week by week — increases in muscle activity are objectively measurable. Daily sessions of 20–30 minutes for at least 8–12 weeks are recommended, then maintenance therapy (1–2 times weekly). Combined effect of EMG-biofeedback and ETS Conventional electrostimulators deliver impulses but do not measure whether the muscles actually respond. evoStim E's EMG channel senses the electrical activity of muscle fibers directly — so you can see in real time if the patient is using abdominal muscles instead of the pelvic floor. ETS goes further: if the EMG signal produced by voluntary contraction reaches the set threshold, the device assists the contraction with electrical stimulation. This combined training can produce more focused muscle work than either method alone. Perineal electrostimulation’s effectiveness stems from excitomotor effects: it can help increase muscle tone and improve local circulation. Studies show stimulation can significantly raise urethral closure pressure and reduce bladder muscle hyperactivity. Package contents evoStim E arrives with the following accessories: 1 pc evoStim E device (touchscreen and rotary knob) 1 pc stimulation cable 1 pc EMG-biofeedback cable 1 pc PeriSphera-O vaginal electrode 3 pcs 1.5V AAA alkaline batteries (LR03) 1 pc battery compartment opener 1 pc user manual Probes and accessories Probes are intended for personal hygiene use. If multiple users are involved, each person must use their own probe. Electrode surfaces are coated with a thin layer of gold plating, so they are suitable even in cases of metal allergy. Spare probes and accessories (PeriSphera, PeriProbe, contact gel) are available on our category page. Frequently asked questions Is the treatment painful? No. You feel a mild tingling and a definite muscle contraction. If you experience pain, reduce the intensity. Treatment should never be painful — if it is, check probe position and parameters. Can I use it during pregnancy? No. Use of electrostimulation devices is forbidden during pregnancy. Treatment can begin after the 6–8 week postpartum medical check-up. What is the difference between evoStim E and evoStim P? Both are biofeedback-enabled stimulators but operate on different measurement principles. evoStim E uses EMG-biofeedback (measuring the muscle's electrical activity), while the evoStim P uses pressure-biofeedback (measuring pressure exerted by the muscle). EMG-biofeedback has the advantage of directly measuring neural activation — it can detect more subtle muscle activity. Can men use it? Yes. Men can use evoStim E with an anal probe (PeriProbe Analis or PeriSphera A) — particularly useful for post-prostatectomy incontinence. EMG-biofeedback can support anal sphincter training as well. How long until improvement is expected? With combined EMG-biofeedback and electrostimulation, initial improvements can be felt after 2–4 weeks of regular use. The intensive treatment phase is 8–12 weeks, followed by maintenance therapy (1–2 times weekly) to preserve results. Which probes can I use? evoStim E is compatible with a variety of probes: vaginal probes (PeriSphera-O, PeriSphera-U, PeriSphera AT) and anal probes (PeriProbe Analis, PeriSphera A). Electrode surfaces are gold-plated and suitable for metal allergy cases. It can also be used with surface (adhesive) electrodes.

Consult your treating physician before use! Important information evoStim E is a CE-marked medical device (MDR certified) intended as a complement to medical treatment. A medical assessment is required before starting treatment to determine the type of incontinence, as different types require different treatment protocols. Electrostimulation can be an effective adjunct to pelvic floor muscle training. The Cochrane Collaboration's 2022 comprehensive review found high-level evidence supporting the effectiveness of pelvic floor muscle training (PFMT) for incontinence treatment.1 The information on this page is for guidance only. Home therapeutic devices are intended to complement medical treatment and do not replace it. Consult your treating physician if you have symptoms.
