Robotic technology became an important tool for rehabilitation especially for stroke patients. This paper presents development of three degrees-of-freedom cable-driven parallel robot (CDPR) for upper limb rehabilitation. Main features of the proposed rehabilitation robot are to provide relatively large workspace and to be less dangerous especially in the situation of robot's malfunction owing to its reduced inertia of a moving part. In addition, the cable-driven rehabilitation robot has many advantages such as transportability, low cost, low actuation power, safeness, large workspace and so on. In this paper, we analyzed the patient's joint movement during the passive rehabilitation using the developed CDPR. In addition, the paper presents the several types of rehabilitation therapy strategies and their implementation using the proposed CDPR system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
