Abstract: Improvement in hand function is one of the major goals of stroke rehabilitation. This paper introduces a newly developed hand rehabilitation device with a user-centered design concept, which integrates fuzzy based quality function deployment (Fuzzy-QFD), morphological analysis method and fuzzy based analytic hierarchy process (Fuzzy-AHP). The design focuses on extension of some certain technical attributes of products to obtain a higher level of user satisfaction. Results of functional test showed that the hand affected due to a stroke could complete the training task successfully by controlling electromyography signals from an unaffected hand. Moreover, for poststroke patients the passive training by voice control is also a suitable alternative. Depending on the actual situation of patients the voice commands could be given by themselves or by therapists. The operation and test results of function showed that the product meet patients’ requirements and has practical significance. The proposed user-centered method also can be applied to the development of similar products.
