Cost-Effective optimization of an Upper Limb Rehabilitation Mechanism

Abstract

In recent years, a vast variety of mechanisms for upper limb rehabilitation have been designed by researchers. The majority of these designs are based on multi degree of freedom and open kinematic chain assemblies. The application of such mechanisms can offer significant aid in successful treatment. Their disadvantages, however, include complexity and costliness. As an alternative to these, other types of mechanisms, such as four and six bar linkages, can be employed in rehabilitation of patients with arm-motion disabilities. These alternative mechanisms are simpler and cheaper, but still have the capacity to offer complex kinematic characteristics.
