SUMMARY:

This research aims to develop a 3D printed modular hand orthosis for patients with Amyotrophic Lateral Sclerosis (ALS) and other neuromuscular diseases, seeking to provide greater autonomy and independence in performing daily activities. The orthosis offers support for the wrist and hand, allowing for quick attachment and exchange of different utensils, such as cutlery, brushes, and writing tools, adapting to individual needs and disease progression.

The study seeks to offer a low-cost, customizable, and easy-to-produce solution, with the goal of making it accessible through the Unified Health System (SUS) in Brazil. To this end, the research investigates the feasibility of 3D printing as a manufacturing method, evaluating the resistance and functionality of the orthosis through simulations and practical tests, aiming at its future clinical application.

The methodology employed included a literature review on the use of orthoses in patients with ALS, mapping their needs and challenges. The prototype was developed using Fusion 360 software, with special attention to comfort and efficiency of use. Finite element simulations were used to test the resistance of the orthosis under different conditions of use. 3D printing of the prototypes used Polylactic Acid (PLA) for the main structure and Thermoplastic Polyurethane (TPU) for the utensil engagement system, combining durability and flexibility.

Preliminary results indicate that the modular hand orthosis has the potential to be a viable, accessible, and effective solution in assisting patients with neuromuscular diseases. However, clinical tests with users are needed to validate its usability in real-world scenarios and to prove its effectiveness in promoting functional independence and social inclusion.
