EDAN PA4 Pro Biofeedback and Stimulation System

The EDAN PA4 Pro is a portable, integrated biofeedback and electrical stimulation system designed for pelvic floor rehabilitation, postpartum recovery, and muscle dysfunction treatment. Featuring 4 independent EMG/STIM channels and 1 pressure channel, the PA4 Pro provides comprehensive assessment, biofeedback training, and electrical stimulation therapy in a single, compact device.

With a built-in operating system, 10.1-inch touchscreen, and 8-hour battery life, the portable PA4 Pro allows physiotherapists and healthcare professionals to deliver pelvic floor muscular assessment and treatment flexibly in any scenario. The system collects and analyzes surface electromyographic (EMG) signals or pressure signals, delivering real‑time biofeedback for the treatment of muscle dysfunctions while promoting blood circulation, providing analgesia, and improving tissue metabolism through electrical stimulation.

Whether you are treating patients with pelvic floor disorders, postpartum women, or individuals with urinary incontinence, the EDAN PA4 Pro offers a comprehensive, non‑invasive solution that combines assessment and therapy in one integrated platform.

Key Features & Benefits

4 Independent EMG/STIM Channels + 1 Pressure Channel

The PA4 Pro is equipped with four independent EMG/STIM channels and one pressure channel. Each channel integrates excellent hardware that provides three working modes:

• Electrical Stimulation – delivers personalized stimulation to 4 body parts simultaneously

• Biofeedback – generates audio‑visual feedback so patients can rehabilitate voluntarily

• EMG‑Triggered Stimulation (ETS) – stimulation is activated when the patient‘s EMG signal reaches the preset threshold

The additional pressure channel enables comprehensive pelvic floor assessment using a vaginal manometer to measure voluntary muscle contraction force.

Precise Assessment Based on Scientific Criteria

The PA4 Pro features assessment methods based on Dr. Glazer‘s evaluation protocol—the international gold standard for pelvic floor assessment. The Glazer Protocol evaluates bioelectrical activity and reflects it in valuable parameters, providing an objective diagnostic method. It includes:

• 1 minute of rest

• 5 rapid contractions

• 5 contractions of 10 seconds

• 60‑second rest followed by a single strengthening contraction

• 1 minute post‑rest

Assessment protocols include:

• EMG Screening – ~3.5 minutes

• EMG Assessment – ~6 minutes

• Quick Screening – ~1.5 minutes

• Vaginal Manometric Assessment – ~3.5 minutes

Unique Signal Extraction Algorithm

The PA4 Pro applies a unique signal extraction algorithm to intelligently capture valuable signals and process them into parameters for the therapist. This saves time and ensures more accurate results. Muscle activity reading is very fast—saving time while making results more precise.

8 Diverse Treatment Methods

The PA4 Pro offers 8 treatment methods to meet clinical demands:

Personalized Therapeutic Programs

Each complete program contains 10 to 15 treatments. All parameters are intelligently adjusted based on the individual assessment report, ensuring fully personalized treatment plans.

Pre‑Set Disease Protocols

The PA4 Pro comes with pre‑set disease protocols for both men and women, covering common pathologies in urology, proctology, and rehabilitation departments. These include:

• Postpartum protocols

• Stress incontinence

• Urge incontinence

• Mixed incontinence

• Post‑surgical treatment

Self‑Adaptive Training Difficulty

During training, muscle fatigue is monitored and training difficulty automatically adapts accordingly to prevent secondary injury. The system also provides automatic visual and audible guidance during assessment to help patients complete the evaluation.

Portable Design with Advanced Integrated Module

The PA4 Pro features a compact, portable design that can be taken anywhere for specialized functional assessment and muscle treatment. The advanced integrated module includes:

• 10.1‑inch touchscreen – intuitive operation

• Android 9.0 – familiar smartphone‑like experience

• 4 control knobs – precise parameter adjustment

• Infrared scanner – quick patient identification

• 8‑hour battery life – extended use without recharging

• Fingerprint lock – secure access and patient data protection

Real‑Time Monitoring and Data Management

• Real‑time monitoring of EMG signals and treatment progress

• Wi‑Fi connectivity – therapists can send reports and treatments to their phone or the patient‘s device

• Intelligent report interpretation – after each assessment, the patient receives a quantified report with intelligent interpretation for the therapist as a reference

• Customized assessment reports for documentation and patient communication
