STUDY OF STRESSES AND VIBRATIONS OF A VIRTUAL ELBOW ORTHOSIS MODEL BASED ON FINITE ELEMENT ANALYSIS

Daniela TARNITA, Cristian-Emilian CHIHAIA

Abstract


The principal objectives of this research endeavor are to mitigate the symptoms associated with osteoarthritis, including joint discomfort and restricted mobility, thereby enhancing patients' overall quality of life. In addressing this research topic, a three-dimensional virtual modeling approach was employed to generate a representation of a market existent physical orthosis, which is frequently used in clinical rehabilitation of the elbow joint. Finite element analysis (FEA) was performed to ascertain the elastic behavior of an elbow orthosis model and its effect on the hand-arm system during demanding instances of customer usage using the Ansys software. A data acquisition platform (Biometrics Ltd.) was utilized to meticulously document elbow flexion-extension and pronation-supination prior to and following a rehabilitation program implemented for a patient affected with osteoarthritis disease.
