[Purpose] Standing and walking are impaired in stroke patients. Therefore, assisted devices are required to restore their walking abilities. The ankle foot orthosis with an external powered source is a new type of orthosis. The aim of this study was to evaluate the performance of a powered ankle foot orthosis compared with unpowered orthoses in a s...


... In contrast to these devices, powered orthoses and exoskeletons are able to provide active assistance to joints, more effectively restoring motion and functional gait [31]. The design and efficacy of exoskeletons and powered orthoses are typically evaluated based on the improvement to kinematics and temporospatial parameters of gait [11,27,43]. However, as these devices have active components, they are inherently heavier than their passive counterparts, and therefore, this additional mass is expected to have some adverse effect on kinetics during walking [25,28]. ...
