Have you been treating yourself for weeks but aren’t sure you’re doing it right? Don’t feel any progress? If you don’t see measurable results in incontinence treatment, you may not be exercising the correct muscle group — or not intensively enough. The evoStim P pressure-biofeedback system provides objective measurement data to show where you stand — and targeted electrostimulation pulses support your training. Why evoStim P? Pressure biofeedback – see what you feel The pressure-sensing probe displays the strength of muscle contractions as objective numbers. No guessing — you can see on the screen whether you’re performing the exercise correctly and track your week-to-week progress. ETS – the stimulator assists ETS (electrically triggered stimulation) detects when you voluntarily contract your muscles and "assists" the contraction with pulses. Your effort and the stimulator’s effect add together — a more focused training than either method alone. 5 program groups – for every incontinence type Stress, urgency, mixed, pain and relaxation — each with 9 predefined programs. With the Intellistim function, frequency can be fine-tuned during a session without changing other parameters. Touchscreen + rotary knob Treatment control is simple and convenient. The touchscreen shows real-time biofeedback curves, while the rotary knob allows quick, precise intensity adjustments. Who is it recommended for? Stress incontinence – leaking when coughing or sneezing Stress incontinence results from weakness of the pelvic floor sphincter muscles. The evoStim P programs at 35–50 Hz specifically train these muscles, while pressure biofeedback shows whether you are engaging the correct muscle group. This is the most common form of incontinence — and one that often responds well to muscle training. Urge incontinence – sudden, strong urge Caused by bladder overactivity: a sudden, uncontrollable urge to void. The evoStim P programs at 10–20 Hz aim to calm the bladder muscle, reducing involuntary contractions. Biofeedback also helps teach relaxation techniques. Mixed incontinence – both types together If stress and urge incontinence occur together, the evoStim P mixed program treats the problem in two phases: first bladder calming (10–20 Hz), then muscle training (35–50 Hz). The device automatically handles the phase transition. Fecal incontinence – treatment with an anal probe With weakness of the anal sphincter, using the evoStim P with an anal probe provides targeted training of the sphincter muscles. Pressure biofeedback is particularly valuable here: you can see whether the anal sphincter actually responds to stimulation. Detailed guide on fecal incontinence → Postpartum rehabilitation Childbirth can damage or overstretch the pelvic floor muscles. The evoStim P can help targeted muscle restoration — pressure biofeedback objectively shows the degree of improvement. Treatment may begin after the 6–8 week postpartum medical check. How to use the evoStim P? 1 Select the program On the touchscreen, choose the program group that matches your incontinence type (stress, urge, mixed, pain or relaxation). Any of the 9 programs can be assigned to the 5 quick-select buttons. 2 Insert the probe Moisten the pressure-sensing probe with water or gel lubricant, then insert it. The probe transmits stimulation pulses and measures the pressure of muscle contractions simultaneously. 3 Set the intensity Slowly increase intensity with the rotary knob until you feel a definite but comfortable muscle contraction. Typically 10–30 mA is the suitable range. The treatment should never be painful. 4 Train using biofeedback The screen shows the pressure trace in real time. In ETS mode the device detects your voluntary contraction and assists it. Contract your muscles on cue — the stimulator’s effect combines with your effort. 5 Track your progress At the end of a session the device stores measurement data. You can compare results week to week — visible improvement motivates continuation. Daily 20–30 minutes for at least 8–12 weeks is recommended. Combined effect of pressure biofeedback and ETS The conventional stimulator works "blindly": it delivers pulses but doesn’t measure whether the treatment actually reaches the target muscles. In contrast, the evoStim P pressure sensor quantifies every contraction — so you immediately know if the probe is badly positioned or if the patient is using the abdominal rather than pelvic floor muscles. The ETS (electrically triggered stimulation) function further increases effectiveness: the device senses voluntary muscle contraction and "assists" it with stimulation pulses. This combined training produces a more focused muscle contraction than either method alone — which can lead to faster improvement.

If multiple people use the device, each should have their own probe. Spare probes and accessories are available on our category page. Frequently asked questions Is the treatment painful? No. You will feel a slight tingling and a definite muscle contraction. If you experience pain, reduce the intensity. The treatment should never be painful — if it is, check the probe position. Can I use it during pregnancy? No. Use of electrical stimulation devices is prohibited during pregnancy. Start treatment after the 6–8 week postpartum medical check. What’s the difference between evoStim P and evoStim E? Both are biofeedback stimulators but work on different measurement principles. The evoStim P uses pressure-biofeedback (measuring the pressure exerted by the muscle), while the evoStim E uses EMG-biofeedback (measuring the muscle’s electrical activity). Pressure biofeedback has the advantage of providing more objective, position-independent measurements. Can men use it? Yes. Men can use the evoStim P with an anal probe — particularly for post-prostatectomy incontinence. Pressure biofeedback also supports training of the anal sphincter. How long until improvement is expected? With biofeedback-combined electrostimulation, initial improvements can be noticed after 2–4 weeks of regular use. The intensive treatment phase is 8–12 weeks, followed by maintenance treatment (1–2 times weekly) to preserve results. Which program should I choose? It depends on the type of incontinence. For stress incontinence choose the muscle training program (35–50 Hz), for urgency choose the bladder-calming program (10–20 Hz), and for mixed forms choose the combined program.

Consult your treating physician before use! Important information The evoStim P is a CE-marked medical device (MDR classification) designed as an adjunct to medical treatment. A medical examination is required before starting treatment to determine the type of incontinence, as different types require different treatment protocols. Electrical stimulation can be an effective complement to pelvic floor muscle training. The Cochrane review of 2022 found high-level evidence supporting pelvic floor muscle training (PFMT) for incontinence treatment.1 Information on this page is for guidance only. Home therapeutic devices are intended to complement, not replace, medical treatment. Consult your physician if you have symptoms.
