Andreas Kontaxis, PhD

About

Research

Dr. Andreas Kontaxis aims to develop world-class products and services that can improve quality of life for patients with painful musculoskeletal and neurological disorders, especially in the upper extremity. His long collaboration with experienced surgeons has inspired him to use research tools, like biomechanical models, to explore and answer challenging clinical questions and create applications that assist the physicians and physiotherapists to optimize clinical outcomes and rehabilitation.

His work involves the development of state-of-the-art biomechanical modeling and kinematics analysis of the shoulder and upper extremity. As a research scientist, he has worked in many individual and international collaborative research programs. He has also published extended work in the development of motion analysis protocols for the shoulder as well as in shoulder joint replacement, with research ranging from osteoarthritis in geriatrics to risk of injury in young athletes.
