Diseño y simulación de una órtesis con materiales pla y abs mediante un software cad/cae para el tratamiento de la parálisis del nervio radial

This study focuses on designing and simulating an orthosis for Radial Nerve Palsy using materials such as ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid). Hand load levels of 0.4, 0.5, and 0.7 kg were tested at three wrist joint angles: extension, flexion, and horizontal. This analysis assessed various parameters, including stress, displacement, deformation, and safety factors. CAD (Computer-Aided Design) and CAE (Computer-Aided Engineering) software created a 3D forearm, hand, and wrist model, considering anthropometric data from the Latin American population. The design methodology included computational simulations and specific anthropometric data, ensuring adaptability and enabling the development of an orthosis design that meets the particular requirements for treating this condition. The results showed a static analysis of the orthosis for the condition, indicating that PLA offers advantages over ABS in parameters such as stress, displacement, deformation, and safety factors. These features suggest that the orthosis presents enhanced stability, support, and durability when subjected to high loads. However, ABS has greater flexibility, making it more comfortable to wear. The study demonstrated that PLA is a superior material to ABS in design. PLA offers enhanced resistance and stability because of its mechanical properties. PLA's rigidity allows for maintaining the correct position of the wrist and fingers, aiding in treating common radial nerve injuries, such as humeral fractures and elbow dislocations, which cause palsy.
