Digital Rehabilitation Solution Company 'Itphy'
Itphy CEO Rhee Sung-min is demonstrating the AI-based digital rehabilitation solution 'RingDoc'.
Many people have experienced the frustration of receiving exercise prescriptions for post-operative rehabilitation but not knowing how to perform them at home. Consistent rehabilitation is crucial, but it is not easy to do alone. There is a company attempting to solve these limitations with Artificial Intelligence (AI) technology. It is Itphy, a resident of Seoul Biohub, a bio-medical startup support platform established by the Seoul Metropolitan Government. We met with Itphy CEO Rhee Sung-min to hear about the changes being created by the AI-based digital rehabilitation solution 'RingDoc'.
Q. My shoulder hurts, why should I exercise?
“Frozen shoulder is a disease where the joint capsule surrounding the shoulder joint hardens due to inflammation. The exact medical term is adhesive capsulitis. A rotator cuff tear is a condition where the tendons that move the shoulder are damaged and torn. Both diseases can cause extreme shoulder pain for patients, to the point where it is difficult to lift their arms above their heads. Appropriate rehabilitation exercises after surgery help recover arm movement. This means the angle at which you can rotate and lift your shoulder increases that much faster.”
Q. What kind of company is Itphy?
“Itphy is a healthcare company aiming for digital innovation in the field of musculoskeletal rehabilitation. We developed RingDoc, a digital rehabilitation platform that precisely evaluates patient conditions and supports customized rehabilitation processes based on AI analysis and non-contact 3D joint measurement technology. Medical staff can prescribe AI-based customized exercises to patients and monitor the patient's treatment compliance and recovery progress in real-time. Patients can also receive continuous and systematic rehabilitation management anytime, anywhere.”
Q. What kind of service is RingDoc?
“RingDoc embodies the meaning of connecting medical staff and patients in a single 'Ring'. The service consists of three parts: RingDoc Motion, RingDoc Web, and RingDoc App, supporting the entire process from diagnosis to rehabilitation management. 'RingDoc Motion' secures quantitative data by measuring the patient's joint status in a non-contact manner without wearing sensors. Medical staff can assign customized exercise plans to patients and manage treatment progress in real-time through 'RingDoc Web'. Patients can perform and record assigned exercises through the 'RingDoc App' and rehabilitate consistently using AI body checks and customized exercise recommendation functions.”
Q. How is patient management conducted?
“Consistent management is key to rehabilitation treatment rather than short-term prescription. RingDoc has a structure where the motion device, web, and app are organically linked to connect patients and medical staff in real-time. When a patient performs exercises while watching videos provided in the app, data is automatically saved, and medical staff can check this remotely to manage progress. AI analysis predicts individual recovery speeds and joint movements, and can automatically adjust exercise intensity and frequency. Thanks to this system, patients can get a hospital-like treatment experience at home, and medical staff can continue efficient patient management.”
Q. What was the motivation for developing the product?
“Existing rehabilitation treatments relied on doctors' empirical judgments and manual measurements, making it difficult to secure objective data. Also, treatment effects were often reduced because patients could not remember prescribed exercises or practice them consistently. In particular, continuous motivation was difficult even in cases requiring steady exercise, such as shoulder disease patients. To solve these problems, we introduced AI-based non-contact 3D joint measurement technology and designed a precise and personalized rehabilitation exercise solution. Seoul Biohub's support for research space, expert advice, and networking was also a great help in the development process and clinical verification.”
Q. Future plans...
“Domestically, we plan to secure clinical data by spreading the RingDoc solution centered on university hospitals and then expand to local hospitals and the general user market. Overseas, we are launching full-scale entry into the global market by establishing partnerships with local institutions, focusing on the US and India. We also aim to secure more than 30,000 users annually by expanding B2C exercise program subscription services that can be used by general users as well as patients requiring rehabilitation. We plan to parallel service advancement and overseas expansion through the TIPS program, export vouchers, and global PoC projects. Seoul Biohub support has been a solid foundation for product development and business expansion. We will strive to grow RingDoc into a standard for digital rehabilitation trusted by both medical staff and patients.”
