Design of Upper Limb Patient Simulator

Abstract Spasticity is one of the muscle diseases in upper limb that is often seen in the patients of stroke and shoulder paralyzed. The disease occur when the patients central nerve is damaged, leading the patients having resistance in the joint when they tries to move it. In the area of orthopedics and rehabilitation, it has become essential to study the characteristics of human joint and muscle diseases. In this paper, an experiment to measure the characteristics of the disease was conducted and the data is used to reproduce the symptoms of spasticity in an upper limb patient simulator. The developed patient simulator is built with the joint and three bones of human arm: humerus, radius and ulna and is evaluated in term of reproducibility of the spasticity stiffness by two experiences physiotherapist.
