Desenvolvimento e validação de um dispositivo para mobilização de tecidos moles com uso de tecnologias 3D

Abstract

Introduction: Instrument-assisted soft tissue mobilization (IASTM) is a therapeutic technique widely used by healthcare professionals to treat musculoskeletal disorders. Aiming to meet patient satisfaction and well-being, new technologies capable of optimizing the use of unique instruments that apply to different treatment cases without compromising the grip and effectiveness of the expected result are welcome in the segment in question. Objective: Develop a device design for soft tissue mobilization through the use of three-dimensional technologies. Methodology: This is an exploratory action research with a qualitative approach, developed in the three-dimensional technologies laboratory (LT3D) of the Center for Strategic Health Technologies (NUTES), located at the State University of Paraíba (UEPB). To achieve the objectives, the study goes through four methodological stages: Marketing and Literary Survey; Conceptual Design; Virtual Modeling through the integration of CAD and CAE; Device manufacturing. After manufacturing, the device was clinically validated. Results and Discussion: A unique device was developed with an arched surface that forms curvatures of different sizes. The computer simulation confirmed that the device was suitable without any risk of failure. Clinical analysis showed that the device is effective. Final Considerations: The model under development is intended for stimulation of superficial tissues, mobilization of deep tissues and breakdown of scar tissue, with a preference for curvatures of different sizes throughout the design with surface variability between concave and convex, with tips similar to a hook, favoring the ideal anatomical fit between the most varied parts of the human body.
