Evidence matters. Here are the real-world results of our retrospective study on BACK4 in pain management, in 89 patients.
89 patients (mean age 46.6), treated by 9 expert physiotherapists between January 2022 and May 2025 for low back pain, knee trauma or surgery, tendinopathy and other musculoskeletal disorders. Winback Protocol: TECAR / RF + Hi-EMS, around 8 sessions of 25 minutes, 2 to 3 times a week.
• 80% pain relief at rest and during movement (highly significant)
• 65% less medication needed after treatment (highly significant)
• 80% of patients reported moderate to strong mobility improvement
• +44% knee flexion, +88% improvement in Schober's test for low back pain
The study has limits: no control group and heterogeneous conditions. Our next step is prospective randomised trials. Bastien Wollensack, Frederic Delacour and our community of passionate physiotherapists are building the evidence together with you.
