Tecar therapy unit BACK4

trolley-mountedEMSTENS

Overview
The BACK4 is an electrotherapy device combining TECAR, Hi-TENS and Hi-EMS currents. It supports static and dynamic protocols, two independent channels and treatment of up to three body areas simultaneously, with an intuitive interface for real-time personalization of therapy.

Key features

• Multi-frequency operation: TECAR, Hi-TENS, Hi-EMS.
• Dual independent channels enabling simultaneous multi-zone treatments (up to 3 zones).
• Power-In patented technology for adaptive, real-time power adjustment based on tissue impedance, electrode size and positioning.
• Quad-core processing to manage concurrent programs and two-channel workflows.
• Modes for clinical use: Academy (preconfigured protocols) and Expert (full manual control).

Frequencies and Modes

• TECAR frequencies: 300 kHz, 500 kHz, 1000 kHz.
• Hi-TENS frequencies: 2 Hz, 5 Hz, 25 Hz.
• Hi-EMS frequencies: 1500 Hz, 4000 Hz.
• Available modes: CET, RET, Hi-TENS, Hi-EMS, MIX.

Power & Performance

• Power: two independent generators, 2 x 100 W (combined >200 W).
• Enables simultaneous use of multiple currents for fast, targeted diathermy irrespective of treatment zone length.
• Designed to deliver rapid clinical protocols while adapting energy delivery for patient comfort.

Standards & Certifications

• Manufactured according to ISO 13485.
• Certifications indicated on product documentation: CE (medical), FDA, KFDA, GMP Korea, FDA Philippines, EMC listings (visual badges on product page).

Dimensions & Weight

• Dimensions: 403.6 x 379.0 x 190.5 mm.
• Weight: Device 6 kg; Trolley 17 kg.

Connectivity & Software

• Secure Wi‑Fi for remote diagnostics, software updates and predictive maintenance.
• Power-In and Quad-core technologies continuously adapt energy delivery in real time.
• U.S. release note: Product name BACK4; Target market United States; Release date September 21, 2023; Software Safety Classification: Class B (IEC 62304); Version 3.11 (initial U.S. release).
• U.S. software constraint: RF and EMS simultaneous operation is disabled in the shipped U.S. configuration (RF and EMS must be operated separately in this configuration).

Accessories

• TX handle (Tecar X) for electrode switching and remote program changes.
• Electrodes (various types), bracelets, adhesive electrodes, neutral return handle, trolley.

Care+ / Protocols & Modes

• BACK4 CARE+ supports manual or hands-free protocols for clinical workflows.
• Academy mode: therapeutic programs for rehabilitation, sports preparation and recovery, women's health and physio-aesthetics.
• Expert mode: full control of currents, intensity and timing for advanced users.

Clinical feedback & use cases (summary)

• Used in rehabilitation, sports medicine, orthopedics and pelvic health contexts.
• Clinicians report applications for athlete preparation/recovery and management of contractures; outcomes depend on clinical protocols and patient selection.
