People with lower-limb injuries often rely on intensive, hands-on physiotherapy to relearn walking, a process that is physically demanding for both patients and therapists and requires constant expert supervision. Traditional methods can be imprecise and fatigue-inducing, limiting the effectiveness of rehabilitation sessions that may last for hours. Onyx Healthcare, a Taiwan-based medical device manufacturer, collaborated with Intel and FREE Bionics to develop FREE Walk, an AI-powered exoskeleton designed to address these challenges by providing consistent, guided movement therapy.
FREE Walk integrates Intel Core Ultra series CPUs and the Intel OpenVINO software stack into a lightweight, wearable exoskeleton. The system uses AI algorithms running on the processor to analyze real-time data from pressure, electromyography (EMG), and inertial sensors, enabling precise gait stability and predictive movement adjustments. OpenVINO optimizes AI model deployment across CPU, NPU, and GPU resources, reducing latency and improving performance for edge AI inference during training sessions.
The exoskeleton supports local edge AI processing for immediate feedback while accumulating training data for cloud-based review and product refinement. This dual approach balances real-time responsiveness with long-term scalability, allowing therapists to reduce staffing needs by approximately 50% per session compared to traditional methods. The system has been adopted by roughly one-third of medical-center-level hospitals in Taiwan and has logged over 40,000 patient training records across 22 countries.
John Chuang, President of Onyx Healthcare, highlighted the collaboration with Intel as transformative for medical device care, emphasizing the role of AI in enabling safer, more efficient rehabilitation. The partnership aims to expand the deployment of advanced AI technologies in clinical environments, with ongoing efforts to enhance the reliability and safety of medical-grade solutions. Performance varies by configuration and other factors.
