Smart, Adaptive Power
With its patented Power-In and Quadcore technologies, Winback is pushing the boundaries of treatment quality.
Power-In continuously adjusts the energy delivered in real time based on tissue impedance, electrode size, and positioning, ensuring ideal energy for maximum patient comfort and enhanced therapist performance.
Equipped with two independent generators, the BACK4 delivers over 200W of optimal power, safely and efficiently. It enables simultaneous use of multiple currents and ensures fast, targeted diathermy, regardless of the treatment zones, path lengths, or therapeutic goals.
Connectivity

"I used BACK4 to treat Red Bull Cliff Diving athletes. I’ve had incredible results with it, both in preparation and in recovery. Some of these extreme divers have named it the “magic machine”! The ability to mix the currents and work on several areas makes me much more effective.
At my practice, I use it for all types of patients: ortho, elderly, athletes.
Apart from the design which is superb, this ability to mix and play with the currents is great."
Mikael DUBIEF
Sport physiotherapist, Arcachon, France
"As a practitioner, it is the first time that I have the feeling to be part of a community of users who share their daily experiences allowing, at the same time, the evolution of the material used. Winback will certainly become a must-have for the tecartherapy and therefore in the physiotherapy practices."
Michaël STASSIN
Physiotherapist, Belgium
"In 2015 , my colleague equipped himself with a BACK3 , which appealed to me! He explained to me as he went along how to use it and especially the results obtained. At the same time, I remember the heel injury of the French pole vaulter Renaud Lavillenie, who suffered a gaping heel wound in February 2014 and who returned to competition 2 months later! Research done, his rehabilitation puts forward the treatment by tecartherapy.... October 2016 I sign for a BACK3SE . The very positive effects appear in the treatment of orthopedic and rheumatological pathologies.
At the same time I start to work in pelvi-perineology thanks to the bracelet. Here too, the results are impressive. In December 2021, I acquired the BACK4, which offers many more possibilities, and I adapted the RET+ Hi-EMS combination for its ultra-fast results in 1 or 2 sessions maximum on contractures that have been in place for several months, and the RET+CET couple. It saves time in rehabilitation and is very comfortable for the patient."

"BACK4 helped me during the Red Bull Cliff DivingOne of my major injuries was the calf because of the impact when diving. Now it's way better. Using BACK4 this week during the competition was awesome!"
Ellie T. SMART
Professional cliff diver at Red Bull Cliff Diving Paris, USA
"I have been suffering from trochanteritis in my left hip for the last 8 weeks and my doctor has prescribed physiotherapy sessions.
I am treated with the new Winback machine, the BACK4 twice a week.
If my pain was 10/10 after 3 sessions, I estimate it to be 5.
This method has given me a lot of relief and has saved me from having to have another infiltration. I could not recommend it enough!"
Nanny
Patient of Michaël Stassin, physiotherapist, Belgium
"For a few weeks, I had been suffering from shoulder pain that extended to my entire right arm. My doctor prescribed physiotherapy. As my husband had already been treated by tecartherapy (and had been very satisfied with it), I chose to be treated by this same technique. By chance, the new machine had just arrived: the WINBACK BACK4. I was thus able to benefit from the first treatments with this machine. I AM AMAZED!
After 6 sessions twice a week, the results are spectacular.
I have no more pain and I didn't even have to stop working to see my situation improve. I highly recommend this technique."
