EDAN PR4 Biofeedback and Stimulation System

The EDAN PR4 is a compact, portable 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 PR4 provides comprehensive assessment capabilities, intelligent treatment protocols, and real‑time biofeedback training in a single integrated device.

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 PR4 offers a comprehensive solution that combines assessment, therapy, and intelligent protocols in one powerful, portable device.

Key Features & Benefits

4 Independent EMG/STIM Channels + 1 Pressure Channel

The PR4 is equipped with four independent EMG/STIM channels and 1 pressure channel, allowing simultaneous treatment of multiple muscle groups or multiple patients. 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.

Intelligent and Customizable Treatment Protocols

The PR4 features an Intelligent Protocol system that automatically recommends personalized treatment plans based on assessment results. The system also includes:

• Disease protocols – pre‑set protocols for common pathologies in urology, proctology, and rehabilitation

• Customized protocols – allowing therapists to create and save their own treatment plans

• Pelvic muscle differentiated training – targeting specific muscle groups with precision

8 Program Segments for Personalized Care

Choose from 8 types of program segments to meet the specific needs of each patient. This flexibility allows therapists to design fully customized training programs tailored to each patient’s unique condition and rehabilitation goals.

Real‑Time Monitoring and Data Management

• Real‑time monitoring of EMG signals and treatment progress

• Customized assessment reports for documentation and patient communication

• Data sharing capabilities for seamless integration with clinical workflows

Portable Design with Extended Battery Life

The PR4 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—up to 12 hours of autonomy—without the need for constant recharging.

Comprehensive Accessories Included

The PR4 system comes with a full set of accessories for immediate clinical use:

• Vaginal pressure sensor (PV) – for pressure‑based assessment

• Intracavity sensors (SV1 disposable, SV2 reusable) – for vaginal applications

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

• Connection cables – 1.6m and 1.8m lengths

• Rechargeable lithium‑ion battery and power adapter

• User manual and quick reference card

Flexible Configuration Options

The PR4 is available in multiple configurations to suit various clinical settings:
