Read full description

DIERS is your movement therapy taking into account a holistic analysis of your musculoskeletal system. A unique feature is the collection of biometric measurement data, which allows incorrect posture and its causes to be identified. Based on these findings, your doctor generates an individual training program. The iDIERS medical device is highly recognized by a large number of health insurance companies. The costs are fully covered by private health insurance. Key facts • Development of therapy with sports scientists, physiotherapists, doctors and universities • Preparation of your therapy plan by your doctor • Easy transfer of the therapy plan to the iDIERS app for training that can be done anywhere, anytime • Continuous adjustment of therapy based on your training results • Comprehensive training statistics and pain diary Detailed usage instructions for the iDIERS app With the iDIERS app, you receive an individual training plan, which is based on the medical history, your activity level and biometric data using an algorithm and is controlled by your doctor. Optionally, the data of your spine measurement can be included in the medical history. For your individual therapy, a pool of over 2000 different training exercises is used, which correspond to the latest training science findings and are explained in detail in video instructions to ensure correct execution. This way you always have your personal training with you. You can constantly work on alleviating your back problems and improving your health in order to lead a pain-free life. The training program consists of self-exercises for which no special aids are required. Additionally, by connecting to the Apple Health app, you can view your steps, traveled distance and number of traveled floors in the iDIERS app. The iDIERS app should not be used if certain contraindications are present (e.g., fresh vertebral fractures, acute myocardial infarction).
