re.flex

What re.flex does

re.flex is a digital musculoskeletal (MSK) physical therapy solution developed and operated by Kineto Tech Rehab SRL, a privately held Romanian limited liability company founded in 2015 and headquartered in Bucharest (with an additional office in Vienna, Austria). The product pairs a mobile app (iOS and Android) with a patented two-sensor hardware kit that tracks body movement in 3D, delivering real-time visual (3D animation) and acoustic feedback on exercise quality and quantity during at-home rehabilitation. It primarily serves patients undergoing knee osteoarthritis (gonarthrosis) rehabilitation, with structured 8–12 week training programs, and targets prescribing healthcare providers (orthopedists, general practitioners, physiotherapists) as the channel to reach those patients.

The core technical differentiator is the proprietary dual-sensor motion-tracking system, which was validated at Charité Hospital Berlin (2019) and Offenburg University (2022) at a 4% average deviation from the Vicon Gold Standard motion-tracking system. The platform is a CE-certified Class I medical device, ISO 27001 compliant, GDPR compliant (data hosted exclusively in Germany via T-Systems servers in Magdeburg and Biere), and is listed as a DiGA (Digitale Gesundheitsanwendung) in Germany under § 33a SGB V by BfArM. The company has an expanding condition-specific product portfolio beyond gonarthrosis: TKR re.store (total knee replacement), Hip OA re.balance (hip osteoarthritis), Lower back pain re.lease, and ACL re.covery.

The business model is subscription/reimbursement-based. In Germany, re.flex is fully reimbursed by statutory and most private health insurers via its DiGA listing; patients receive an activation code from their insurer, the sensor kit is provided through a lending model bundled into the reimbursed price, and billing is processed through Noventi HealthCare. Go-to-market in Germany runs through an exclusive channel partnership with SPORLASTIC GmbH, a long-established orthoses manufacturer that handles sensor distribution, activation, and provider outreach. In the UK, patients access the product via self-referral or private hospitals on an out-of-pocket/private-pay basis. Access is currently restricted to Germany and the UK.
