[Conference paper] Wrist Rehabilitation Equipment Based on the Fin-Ray® Effect – Abstract + References


A swift post-traumatic recovery of upper limbs can be achieved best by means of dedicated rehabilitation equipment. A speedy recovery process ensures the early reintegration of patients into society. The rehabilitation equipment proposed in this paper is conceived for the simultaneous passive mobilization of the radiocarpal, metacarpophalangeal and interphalangeal joints. The paper presents and discusses the construction and actuation system of the equipment. The elements of novelty put forward by this equipment refer to the Fin-Ray® effect underlying the design of the hand support and to its operation by means of a pneumatic muscle – an actuator with inherently compliant behavior. The discussion includes the occurring of hysteresis, and concludes that it does not affect the efficiency of the rehabilitation exercises..
