Diseño e implementación de una plataforma para la evaluación biomecánica de sobrecargas en la región cervical

Abstract

This study describes the development of Postural Assessment and Testing for You (Paty) as a tool for measuring angles in the cervical region and analyzing postural changes through images to support the biomechanical evaluation of overloads in this area. The tool was developed in Python with PyQt5 to measure angles in the frontal and sagittal planes, identifying postural deviations through vector calculations. Based on weight data, it can also determine whether the backpack load is excessive. Tests were conducted comparing Paty with the Kinovea software, showing a high correlation, with angular differences of less than 1°. The evaluation included conditions with and without a backpack and carrying it on the right and left shoulders. Results showed that carrying a backpack on one shoulder leads to trunk inclination and increased head tilt. The study concludes that the tool is reliable and emphasizes the need for postural education to prevent overload-related injuries.
