Passive type 3D motion devices for upper limbs

Generally, rehabilitated patients can generate a motion through therapists or special devices. On the view of patients, these devices are a passive motion generator. Therefore we define the devices as a passive type. Most passive type devices for an upper limbs' rehabilitation have the structure of manipulator. As is well-known, this manipulator type device for upper limbs needs separate and not less spaces for the installation. In this paper, we propose a simple mobile type device for an upper limbs' rehabilitation motion that can move on a table and generate the 3D motion of patients' upper limbs. Further this needs not separate spaces for an installation.
