Medical conditions or accidents, such as stroke, can cause significant neurological damage to the human body and cause loss of motor function in the upper extremity, the patient's hands. Various robotic devices such as exoskeletons have been designed to assist humans in the rehabilitation process; however, they have limited features that do not achieve optimum performance. Hand rehabilitation treatment of patients is carried out in clinics and under the guidance of an expert using various hand rehabilitation devices. The task of the devices used in the rehabilitation of the hand is to provide passive, active or active assisted rehabilitation therapy to the hand. However, hand rehabilitation devices do not have any standards. In this study, mechanical designs and drive mechanisms of hand rehabilitation devices are described and compared.
