Recent Patents on End Traction Upper Limb Rehabilitation Robot (E-pub Ahead of Print)
Background: To meet the increasing requirements of patients and to
reduce the pressure of doctors, more and more structures of rehabilitation
robots have been designed and improved constantly. The end traction upper
limb rehabilitation robot has the advantages of simple structure, easy
control and low cost. Its main mechanism is composed of a serial robot
mechanism and a connecting rod mechanism. It uses the motion of robot to
drive the upper limb of patients to achieve the purpose of rehabilitation
Objective: To provide an overview of recent end traction upper limb
rehabilitation robot and introduce their respective characteristics and
