People suffering from a motor disorder or disease run the risk of relying too much or too long on compensatory movement behavior to try and cope with the changed organismic constraints. Overcoming unnecessary, bad habits in motor performance requires carefully monitoring movement behavior during rehabilitation. In this thesis the Solution Space Model is central in the examination of the movement behavior in knee osteoarthritis and after a Total Knee Arthroplasty. Due to compensatory movement behavior the non-affected leg cannot serve as stable frame of reference to accurately predict recovery outcome after a Total Knee Arthroplasty, the upper extremities and/or trunk may serve as stable frame of reference instead. The results of this thesis show less automatized and more predictable movements during treadmill walking in people with knee osteoarthritis compared to healthy controls. Furthermore, compensatory movement behavior of the legs during treadmill walking was found 12 months after Total Knee Arthroplasty. Finally, the degree of (un)predictability the trunk’s lateral sway may serve as stable frame of reference to predict walking ability after Total Knee Arthroplasty.
