Stroke patients might lose their action for limbs act conseq�ently. If th � y ha : e not been treated with independent rehabilitation or external force rehabilitation in the long run, hmb dysfunctIOn might be h � ppened to them. The purpose of this study is to develop a set of finger joints rehabilitation syst � m. An� mechamsm an� control technology are integrated in this rehabilitation device. With regards to the mecham � m design, to use of micro gear motor with the screw as the way of transmission and it is driven by using link mechamsm so as to act the fing � r plates. The flexion and extension of the finger can be done by the action of finger plates eventually. As for the mterface system, it uses the embedded systems. It is done by inputting oper � t . ing . condit�ons through a touch panel.. Moreover, to install the sensor of angle, displacement and pressure on the rehabIlItatIOn devIce so as to feed b � ck the slgn � l � to back to the embedded system for data recording in order to provide the needed rehabilitation informatIOn for � hyslclan � o . as to attest the performance of the rehabilitation as well. It can truly improve the performance of the entrre finger Jomt rehabilitation device system a lot.
