HandCARE2: A novel cable interface for hand rehabilitation

摘要

We have developed a novel robotic interface to train hand and finger function. HandCARE2 is a Cable-Actuated REhabilitation (CARE) system, in which each finger is free to move in space with a large range of movement, from a closed hand to full extension. The device, designed based on biomechanical measurements, can assist the subject in opening and closing movements of the hand and can be adapted to accommodate various hand shapes and finger sizes. The system uses a cable-spring transmission and a clutch system, which allow movement combinations of the five fingers with only two actuators. The device is safe, cost effective and offers multiple possibilities to train finger independence and coordination, with various grasps.
