Abstract: The discussed matter is comprised of a biomechanical vest designed to optimize body posture and movement. Specifically, the equipment consists of a vest which has areas reinforced by a material that simulates the elastic tension usually provided by body structures. These areas of tensional reinforcement follow patterns of the musculoskeletal system architecture and aim to give appropriate support for posture and movements of children and adults with motor dysfunctions, as well as optimizing the performance of workers and sports practitioners during their activities.
