Evaluación de riesgos ergonómicos asociados a las posturas y movimientos adoptados por el personal del área de pediatría encargado del cuidado de neonatos, mediante análisis cinemático por fotogrametría.

In Ecuador, hospital staff are at high risk of developing musculoskeletal disorders due to the physical demands of their tasks. However, this issue has not been thoroughly studied in order to mitigate ergonomic risks effectively. This project aims to evaluate the postures of healthcare personnel responsible for neonatal hygiene and feeding using photogrammetry tools, and to identify potential ergonomic issues arising from these activities. This methodology allows for the recording and analysis of movement patterns. Data were collected using the Kinescan camera system and the Kinect depth sensor, and the analysis was supported by software tools such as Tracker. Angular kinematics were calculated using the Mozzi/Rodrigues method, and the results were validated using the Coefficient of Multiple Correlation (CMC) and the Standard Error of Measurement (SEM), ensuring the reliability and accuracy of the method. A total of 21 participants with no prior musculoskeletal injuries took part in the study, and a mannequin with anthropometric characteristics similar to those of a real newborn was used. This study provides a quantitative basis for identifying ergonomic risk factors and proposes guidelines for redesigning clinical tasks to improve occupational health for medical staff. Additionally, a specific analysis of head and neck effects was conducted using jerk acceleration as a dynamic variable.
