Abstract :
Stroke affects millions of people every year. Most of them need rehabilitation to recover their mobility. Although a lot of robotic based devices have been suggested for rehabilitation of the hand muscles, these devices still need some improvements. Methods using for transmitting movement and force in previous devices have some disadvantages. One of them is misalignment on the centre of rotation between joints used in devices and joints of the hand and the wrist. This situation causes a shear force on the joints of human limbs. To resolve these problems new approaches should be proposed. In this study a novel device is suggested to perform the wrist exercises. The device has a cable and spring-driven system for transmitting movement and force. Thus, it does not cause the alignment problem on the centre of rotation. The device allows both passive (assistive) and active exercises. It is aimed that the device is suitable for home use, portable and low cost. The proposed new device expected to reduces the rehabilitation cost and therapy period. The device can be used for other situations such as nerve injury, nerve compression, tendon injury, fracture and sport injury besides stroke rehabilitation. If this low cost device can be commercialized, it is clear that, it may contribute to Turkey competitiveness capacity on the global medical markets.
