Both groups gain a significant benefit from the gradual intensity build-up during use, allowing both therapist and patient to safely find the optimal stimulation level. Documenting therapeutic results enables long-term therapy monitoring and adjustment if needed, increasing treatment success.

Innovations of evoStim UG

One of evoStim UG’s key technological innovations is the combination of a touchscreen interface and a unique rotary knob, enabling intuitive and precise control.

The device features an innovative automatic waveform regulation that operates independently across two channels and adapts to the probe type used.

This function ensures optimal therapeutic effect with maximum comfort, whether using ring or lateral electrodes.

How perineal electrical stimulation works

Perineal electrical stimulation is a scientifically validated therapy, particularly effective for various forms of incontinence.

The electric impulses used work with a complex mechanism on the pelvic floor area. Stimulation primarily increases muscle tone and improves blood circulation.

Research shows that the treatment significantly elevates urethral closure pressure and positively affects bladder function.

Pelvic floor muscle strengthening and rehabilitation

Electrostimulation is especially effective in strengthening pelvic floor muscles.

When pubococcygeal muscle strength is low (Oxford scale 1 or 2), vaginal electrotherapy can yield quick improvements. Treatments typically enhance muscle strength by at least two scale points. This improvement results not only from increased muscle tone but also better blood flow, promoting muscle regeneration and strengthening.

Treatment protocols for different incontinence types

For stress incontinence, evoStim UG applies relatively high-frequency electric impulses, generally between 35-100 Hz. This range stimulates the phasic muscle fibers, causing strong but brief contractions. Treatment sessions last about 20 minutes daily, with contraction times progressively increasing as muscles strengthen. Pulse width is adjustable between 100-400 microseconds based on patient sensitivity.

For urge incontinence, resulting from bladder detrusor instability, lower frequencies of 5-10 Hz are suggested. Pulse width typically optimizes between 250-400 microseconds. The protocol starts with one daily session in the first week, then decreases to 2-3 sessions weekly over the next 3-4 weeks.

Mixed incontinence, accounting for about 40% of cases, features both types. Treatment strategy considers the dominant component. Since urge symptoms often respond faster, these are usually treated first.

An alternative is performing two daily sessions separately focusing on urge and stress components.

evoStim UG programs

evoStim UG includes five main program groups for different therapeutic targets.

• The URGE group (P10-P19) targets urge incontinence treatment.
• STRE programs (P20-P29) are optimized for stress incontinence.
• MIX group (P30-P39) addresses mixed incontinence.
• PAIN programs (P40-P49) manage pelvic pain.
• RELX program (P50) helps pelvic muscle relaxation.

IntelliSTIM function and programming options

Its unique IntelliSTIM function in the five default programs (P10, P20, P30, P40, P50) allows frequency modification without manual adjustment of other parameters.

Automatically, it optimizes pulse width and other settings for the selected frequency, ensuring maximum therapy efficiency.

Each touchscreen button (main program group) can hold up to 10 fully customizable programs, offering great flexibility for personalized treatments.

Safety instructions and contraindications

Use of evoStim UG is strictly contraindicated in certain cases.

• Use during pregnancy is forbidden.
• Patients with pacemakers or severe cardiac rhythm problems cannot use the device.
• The therapy is not to be applied while driving or operating machinery.
• Epileptic patients may only use it after medical consultation; use in children under 12 requires strict medical supervision.

Specific contraindications

Perineal electrotherapy’s specific contraindications include kidney diseases, active lower urinary tract infections, and pelvic tumors.

Treatment is not recommended with residual urine volumes over 100 ml or presence of vesicoureteral reflux.

A subjective contraindication is patient rejection or hypersensitivity to electrical stimulation.

Practical application

Thorough preparation and understanding of safety rules are essential before starting treatment.

The device uses three AAA 1.5V alkaline batteries.

Wires connect to ports on the device’s bottom; single channel use requires connection to the CH1 port.

Probe preparation and use

The probe should be moistened with tap water or water-based gel before use to ensure conductivity.

Insertion should be done carefully following medical guidance or probe instructions.

Stimulation intensity should be increased gradually until achieving a comfortable level causing noticeable muscle contraction.

Treatment procedure

Select the appropriate program from the five main groups before starting. Choice depends on patient condition and problem type. The touchscreen and rotary knob make navigation and parameter setting easy.

Intensity control

The device includes an automatic safety system that stops stimulation if circuit breaks or excessive resistance occur, preventing unwanted or excessive stimulation.

Intensity is adjusted gradually and can be fine-tuned during treatment.

Maintenance and hygiene instructions

Cleaning is crucial for device function and hygiene.

Use a soft, mildly alcohol-based wipe (Clinell device disinfecting wipe), avoiding water-based cleaners.

Perineal probes are for personal use only to avoid cross-infections.
