Towards the development of more human-like robotic therapy devices: A review

Over the past decade, more and more robotic devices have been tested in the physical rehabilitation setting. While initial results from some devices indicate signs of improvements in subject's motor functions, some studies reveal the contrary. The contradicting results from these studies highlight the need of optimizing the design strategies of robotic therapy devices. In the absence of clear scientific basis for the designs of such devices, researchers should rely on proven principles of physical rehabilitation practices. In order to achieve their goals, robotic devices should become more human like in connecting intent with actions.
