evoStim UG Dual Channel Perineal Electrical Stimulator
evoStim UG is a perineal electric stimulator - also referred to as Pelvic Floor Stimulator - for use with vaginal and anal probes. Equipped with unique features, versatile and high performance, the evoStim UG features 2 independent channels, a touch screen with unique rotating knob, touch buttons and a user-friendly interface for unparalleled ease of use by professionals at clinics and by individual users at home.
Perineal stimulation (i.e. pelvic floor stimulation) is a proven and commonly used therapy for all types of incontinence and pelvic floor rehabilitation. Pelvic floor stimulation aims to stimulate perineal muscles, especially the pubococcygeal and puborectal muscles.
Pelvic floor stimulation using vaginal probes with ring or lateral electrodes is highly successful in strengthening and rehabilitating pelvic floor muscles and restoring continence in women. The type of the stimulation probe chosen determines the type of stimulation waveform to be used for best therapeutic outcomes. Biphasic symmetrical pulses work best with probes with ring electrodes, whilst alternate biphasic pulses are most suitable for use with probes featuring lateral electrodes. The evoStim UG features automatic wave-shape selection on each channel, depending on the type of probe selected (i.e. probe with ring or lateral electrodes).
Pelvic floor stimulation improves pelvic floor muscle tone, increases blood flow in the pelvic area and strengthens the pelvic floor muscles. A significant increase in the urethral closure pressure has been reported as well as a significant improvement in bladder tone, reduction in detrusor contractions and an improvement in bladder capacity.

Designed with a clear aim to make pelvic floor stimulation more effective and comfortable, the evoStim UG Perineal Stimulator offers a true therapeutic advancement. Regardless of the type of stimulation probe chosen (i.e. probes with ring electrodes or probes with lateral electrodes), the evoStim UG always delivers optimum therapeutic outcomes.
5 of the pre-set programs benefit from the IntelliSTIM function, which automatically adjusts Work/Rest parameters, when the user changes the frequency of the stimulation program. The IntelliSTIM function makes using of the evoStim UG far simpler by comparison to other stimulators and most importantly, prevents parameter errors that can easily be made by inexperienced or unskilled users.
evoStim UG therapeutic indications
evoStim UG is indicated for the treatment of urinary incontinence – stress incontinence, urge incontinence and mixed incontinence and other pelvic floor related problems.
- Treating Stress Incontinence with Pelvic Floor Stimulation
Stress incontinence is caused by urethral sphincter deficiency. Symptoms of stress incontinence include involuntary leaking of urine during coughing, jogging or running, sneezing, rising from a chair and other strenuous activities that cause an increase in abdominal pressure.
The aim of the pelvic floor stimulation in the treatment of stress incontinence is to improve the voluntary control of pelvic floor muscles. An effective treatment of stress incontinence requires restoring of the pelvic floor muscle strength and endurance. To achieve this, patients should persevere with pelvic floor stimulation treatments over a long period of time, during which small steps improvements are achieved gradually and continue until resolution is achieved.
Stimulation treatment should be performed every day for 20 minutes. Stimulation therapy should commence with short work periods and as the muscles begin to grow stronger, gradually build-up endurance by increasing duration of contractions. Stress incontinence is normally treated with relatively high frequency electrical pulses, ranging from 35 to 100 pulses per second (i.e. 35 – 100 Hz) with the aim of exercising muscles fibres with strong short contractions. Pulse width should be selected between 100 – 400 microseconds.
When using pelvic floor stimulation to treat stress incontinence, the purpose of the stimulation is to induce pelvic floor muscle contractions. During stimulation, gentle tingling sensation is felt. When pelvic floor muscles contract and the pelvic floor lifts, the external part of the vaginal probe tilts visibly down. Simultaneously with the contraction, the patient feels tightening of the pelvic floor. Please note that pelvic floor stimulation does not cause damage to pelvic floor muscles, however, the stimulation should not feel uncomfortable, because discomfort can reduce motivation of the patient to participate in the therapy long term. If a discomfort is felt, intensity level should be reduced appropriately until comfort is apparent.
- Treating Urge Incontinence with Pelvic Floor Stimulation
Urge incontinence is caused by detrusor instability. Detrusor is the smooth muscle in the wall of the bladder. When healthy and well-functioning, the detrusor is relaxed during urine storage in the bladder and contracts to empty the urine from the bladder. Urge incontinence (i.e. overactive bladder) is a condition characterised by detrusor instability (i.e. spontaneous uninhibited contractions of detrusor muscle during bladder filling stage), leading to frequent urge to pass urine and/or urine leakage.
The goal of the pelvic floor stimulation in the treatment of urge incontinence is to strengthen the reflex inhibition of the detrusor muscle. The most appropriate frequency to be used for overactive bladder (i.e. urge incontinence) is between 5 – 10 Hz with a pulse width of between 250 – 400 microseconds. The stimulation is most effective, when performed daily for the first week and then 2 – 3 times per week for the next 3 – 4 weeks.
Low frequency level stimulation used in the treatment of urge incontinence does not cause contractions and therefore there are no movements of the external parts of the vaginal probe to be seen. The stimulation is most effective at highest intensity levels. Any discomfort felt by the patient at the early stages of stimulation diminish with time and it is therefore possible to increase the intensity to the therapeutically desirable and more effective high intensity level.
- Treating Mixed Incontinence with Pelvic Floor Stimulation
Mixed incontinence accounts for circa 40% of all urinary incontinence cases. Mixed incontinence is characterised by episodes of stress incontinence caused by straining with increased abdominal pressure alternating with episodes of urgency caused by detrusor instability, also described above.
Depending on predominance of the contributory incontinence (i.e. stress or urge), mixed incontinence can be treated with a relatively high frequency (i.e. 75 Hz) for greater effects of stimulation on the muscle tone and strength or with lower frequencies for greater effects on detrusor muscle.
Urge incontinence normally responds faster to stimulation treatment than stress incontinence, hence it is best to treat urge incontinence first and subsequently follow with treatments for stress incontinence. Alternatively, 2 treatments per day can be performed, one for urge incontinence and one for stress incontinence.
