Validación de kinovea como herramienta para el análisis de posturas en tareas sedentarias: validación de kinovea con fotogrametría.

Abstract

The objective of the study is to validate the Kinovea software for the analysis of postures in sedentary tasks, the postures of students and workers who, due to the pandemic caused by the SAR-CoV-2 virus, adopted teleworking in their homes and present ailments are analyzed. caused by remaining in non-ergonomic postures during their working day. To determine the ergonomic risk, the statistical analysis of the information obtained from the survey is carried out and videos of the volunteers are observed in their normal work day to establish movements, postures and scenarios that will be reproduced in the biomechanics laboratory of the National Polytechnic School. in order to obtain position data for validation. The selected postures and movements are reproduced in a controlled environment according to the established experimental procedure, it is monitored with two systems, the first is the set of cameras of the photogrammetry laboratory associated with Kinescan and the second with a mobile device and the normal camera. In the laboratory, the videos that are analyzed with Kinovea are recorded. A correlation analysis is performed comparing the averages of the neck movement cycles obtained with both programs, which determines that Kinovea can be used for the analysis of sedentary postures.
