Together with the tools from biomechanics, robotics enables our efforts to explore natural human motion, leading to improvements in treatments for patients with neuro-musculoskeletal disorders, and facilitating development of human-inspired robots. Using robotics methods and control theory, we aim at gaining fundamental insight into natural human movement, and understanding the mechanisms that lead to improved quality of treatment and rehabilitation. Using biomechanics,we aim at exploring the relationships between muscle mechanics, form, and function, and creating subject-specific dynamics simulations to explain the causes of movement abnormalities.
