Abstract:We have developed a robotic interface to train hand and finger function.
HandCARE
is a Cable-actuated rehabilitation system, in which each finger is
attached to an instrumented cable loop allowing force control and a
predominantly linear displacement. The device, whose designed is based
on biomechanical measurements, can assist the subject in opening and
closing movements and can be adapted to accommodate various hand shapes
and finger sizes. Main features of the interface include a differential
sensing system, and a clutch system which allows independent movement of
the five fingers with only one actuator. The device is safe, easily
transportable, and offers multiple training possibilities. This paper
presents the biomechanical measurements carried out to determine the
requirements for a finger rehabilitation device, and the design and
characterization of the complete system.
