This study depicts the use of a three-dimensional virtual modeling approach to create a representation of a physical orthosis commonly utilized in the clinical rehabilitation of the elbow joint. A finite element analysis (FEA) was conducted, involving static and dynamic analysis. A comprehensive understanding of orthosis stiffness, coupled with the ability to regulate it both statically and dynamically, holds considerable promise in the treatment of elbow diseases. A data acquisition system (Biometrics Ltd.) was employed to record elbow flexion-extension and rotation angles before and after a rehabilitation program for a patient suffering from arthritis disease. The findings from this research show that an elbow orthotic device designed for stability has a considerable impact.
