WINBACK BACK4
Multi-frequency tecar therapy device
In short
- Combines three currents: TECAR, Hi-EMS and Hi-TENS.
- Over 200 W of power and treatment of three body areas at once.
- TecarX (TX) smart handpieces that recognise electrodes and let you work with both hands.

A new era of therapy
BACK4 combines several currents known for their therapeutic benefits: TECAR (high frequency, 300 kHz to 1 MHz: cellular, diathermic and analgesic effects), Hi-EMS (medium frequency, 1.5 to 4 kHz: deep muscle stimulation) and Hi-TENS (low frequency, 2.5 to 25 Hz: relief of acute and chronic musculoskeletal pain).
Power and speed
With over 200 W, BACK4 is the most powerful device in the Winback range, and the brand presents it as the safest device on the market. It can treat three body areas at the same time and, according to Winback, halves treatment time compared with traditional TECAR.
TX: the smart handpiece
TecarX (TX) is a patented innovation. The smart handpieces let you work with both hands and use the whole Winback electrode range during treatment. They automatically recognise the electrode type and programme, work in smart mode (CET, DEEPCET RET, MIX, Hi-RET) and in assisted mode (fixed pads, adhesive pads, mobile plates and bracelets). Motion sensors let you control BACK4 remotely, select modes and adjust power through movements.
Who it is for
Physiotherapy clinics, rehabilitation centres, sports club medical services and hospitals looking for a versatile device for sport and rehabilitation.
