Evaluation of simplified repeated resistance training system for severe hemiplegic stroke patient

We have developed a three-dimensional force display robot (3D robot) to discover and embody needs in rehabilitation site. Then we have exchanged opinions with therapists by using the 3D robot together in rehabilitation site. From a therapist' needs we have developed repeated resistance training system by using the 3D robot as one of the application of the 3D robot. On the basis of the results we have developed a simplified repeated resistance training system equipped with a user interface for easy operation for therapists. Moreover, we have developed a brace for fixation as the attachment between the training system and the patient's arm. In this paper, we perform the functional evaluation of the simplified repeated resistance training system and the brace in the clinical site. These results are based on the opinions from the therapist and the patient. Moreover, we verify the therapeutic effects of the repeated resistance training using the simplified system for a hemiplegic stroke patient. The AROMs of pronation and supination of the patient were improved after repeated resistance training using the simplified system.
