1 in 3 people worldwide suffer from musculoskeletal disorders, costing over500B USD annually in the U.S.(BMUS 2020, WHO 2022) Yet, diagnosis usually happens after pain, through MRI or X-ray, making early functional decline hard to detect.
When treatment continuity breaks outside hospitals and access to rehabilitation varies by region, the burden of recovery falls on patients. That’s why we need a system that can detect joint dysfunction early, track changes quantitatively, and continue therapy in daily life.
Fromjoint screening to
digital therapeutics, all in one.
4DEYE bridges prevention and rehabilitation with early detection and precise analysis.
4DEYE is the first AI rehabilitation platform to seamlessly integrate screening and therapy. Through a cycle of screening → analysis → treatment → follow-up, we deliver personalized rehabilitation.
Joint dysfunctionbegins before pain,
but rehab often stops outside hospitals.
