EDAN PA4 Biofeedback and Stimulation System

The EDAN PA4 is a portable biofeedback and electrical stimulation system designed for functional rehabilitation, with a strong focus on pelvic floor therapy and urogynecology protocols. Featuring 4 independent EMG/STIM channels and 1 pressure channel, the PA4 combines real‑time biofeedback tracking with functional electrical stimulation to deliver precise, repeatable clinical sessions.

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 offers a comprehensive, non‑invasive solution that combines assessment and therapy in a single integrated platform.

Key Features & Benefits

4 Independent EMG/STIM Channels + 1 Pressure Channel

The PA4 is equipped with four independent EMG/STIM channels and one pressure channel for comprehensive functional assessment and treatment. Each channel supports three working modes:

• Electrical Stimulation – delivers personalized stimulation to multiple 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.

Real‑Time Biofeedback for Therapy Tracking

The PA4 provides real‑time biofeedback that allows patients to see their muscle activity during exercises, promoting voluntary muscle control and engagement. This visual feedback helps patients understand proper muscle activation patterns and accelerates rehabilitation outcomes.

Electrical Stimulation for Functional Rehabilitation

The system delivers electrical stimulation for functional rehabilitation, helping to activate weakened muscles, promote blood circulation, provide analgesia, and improve tissue metabolism. The practical interface ensures precise, consistent sessions.

Portable Design with Built‑In Battery

The PA4 features a compact, portable design that can be taken anywhere for specialized functional assessment and muscle treatment. The built‑in rechargeable lithium‑ion battery (14.4V, 6800mAh) provides extended use without the need for constant recharging.

Pre‑Set Disease Protocols

The PA4 comes with pre‑set disease protocols 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.

Real‑Time Monitoring and Data Management

• Real‑time monitoring of EMG signals and treatment progress

• Customized assessment reports for documentation and patient communication

• Postpartum protocols for postnatal recovery

Comprehensive Accessories Included

The PA4 system comes with a full set of accessories for immediate clinical use:

• Vaginal pressure sensor (PV)

• Intracavity sensors (vaginal) – disposable and reusable options

• Body surface electrodes – various sizes and shapes (rectangular, square, crescent)

• Connection cables – 1.6m and 1.8m lengths

• Rechargeable lithium‑ion battery (14.4V, 6800mAh)

• Power adapter

• User manual and quick reference card

Clinical Applications

The EDAN PA4 is designed for a wide range of pelvic health and rehabilitation applications:
