Musculoskeletal (MSK) conditions are the leading cause of pain and disability worldwide, affecting mobility, independence, and quality of life for millions. Traditional assessment methods, generally based on clinical observation and subjective reporting often miss early functional decline and subtle compensatory patterns that precede structural damage. The lack of scalable, objective tools for movement analysis has long limited clinicians' ability to detect early dysfunction, personalise rehabilitation, and monitor treatment response. Bridging this diagnostic gap is crucial to enable earlier intervention, improve long-term outcomes, and reduce healthcare burden.

MAI Motion was developed to meet this challenge. It is an AI-powered, marker-less motion analysis platform designed for real-world clinical use. By capturing high-resolution biomechanical data through a single camera, MAI Motion quantifies control, symmetry, and flow of movement without the need for specialised laboratories. Using machine learning algorithms, it generates objective, repeatable metrics that track performance, recovery, and risk over time. The system provides clinicians with clear, visual feedback while offering patients tangible insight into their own movement quality — turning motion into measurable, actionable data.

At the United European Academy Conference 2025 in Casablanca, Professor Paul Lee presented \"MAI Motion – The Future of Musculoskeletal Health and Movement.\" The presentation highlighted how AI-driven motion science is transforming MSK care through early detection, prevention, and personalised treatment. Supported by MSK Doctors, the University of Lincoln, and Innovate UK, the project exemplifies how cutting-edge technology can translate from research into clinical practice.

By integrating biomechanics, artificial intelligence, and regenerative medicine, MAI Motion provides a framework for a new era of musculoskeletal health, one centred on objective measurement, proactive care, and patient empowerment. As European collaborations expand, this initiative is positioned to lead the transformation towards regenerative orthopaedics and preventative medicine across healthcare systems.
