What patients say about re.flex.
We asked patients what their experiences with re.flex were.
Frequently asked questions
re.flex is a digital exercise assistant designed for covering both pre & post operative use cases of patients with ACL, total knee & total hip replacement and also preventative care cases for knee & hip osteoarthritis and lower back pain.
With 2 motion sensors and a 2-3 month digital training program as a patient you are guaranteed to ensure an improved exercise control throughout your physical therapy journey.
The patented sensor technology specially developed for exercise therapy enables meticulously precise recording of your movements and provides you with almost instantaneous feedback on the quality and quantity of your movements.
The movement visualization sequences are shown in real-time as 3D animation in the re.flex app. The 2-sensor technology ensures reliable angle measurement.
The effectiveness of re.flex has been validated in several clinical studies in Germany. After 12 weeks of training, re.flex showed a significant reduction in knee pain for patients diagnosed with gonarthrosis.
Health improvement:
- Reduction of pain (KOOS pain)
- Reducing Difficulty in Activities of Daily Living (KOOS ADL)
The guided exercises in sports and movement therapy are aimed at stabilizing the affected knee joint and reducing abnormal joint loads by improving muscular stabilization, which leads to a reduction in the pain felt and an increase in functionality.
re.flex is a class I medical device and is compliant with the ISO 27001 standard for information security. The accuracy of the device was first validated in 2019, with Charite Hospital in Berlin (Germany), resulting in a 4% average deviation from the Gold Standard of motion tracking movement, which means a very good result. Later on, in 2022, a second accuracy validation study was completed with Offenburg University, with comparable results being recorded.
The safety of re.flex has been validated in several clinical studies. The re.flex training program for gonarthrosis was developed in cooperation with the sports medicine department of the University Hospital in Tübingen.
re.flex manages to secure public reimbursement in Germany, the largest European healthcare market. Since 2022, re.flex is officially listed as DIGA. More information about the DIGA re.flex: DiGA-Verzeichnis
