[A Public Database of biomechanical parameters of gait in young Chileans].

Biomechanical analysis of gait encompasses the measurement of spatiotemporal (STVs), kinematics, and kinetics variables. The behavior of these variables can provide clinicians and researchers with insights into the normality or alteration of this motor act across different populations. However, there is a lack of reference data for the Chilean population.

Aim: To present a freely accessible database including STVs, kinematics, and joint kinetics of 51 healthy Chilean individuals during gait.

Methods: 51 healthy volunteers aged 18-30 years were included in the sample. The MOCAP Vicon system with the Plug-in Gait Lower Body Functional model was utilized for biomechanical model creation and analysis. At least five valid gait trials per individual were recorded at a self-selected speed, with participants stepping on embedded force platforms. Based on this information, STVs, kinematics, and joint kinetics were computed. These data were graphically represented for each plane, utilizing the average value of both lower extremities.

Results: The findings were summarized in a table and five distinct figures. The variables of interest were exported and made available in ".csv" format on the Figshare platform (DOI: https://doi.org/10.6084/m9.figshare.22151474). Similarities in morphology and magnitude were observed compared to other databases from foreign studies.

Conclusion: Data regarding STVs, kinematics, and kinetics of gait in the Chilean population are provided, facilitating future research and clinical applications in this demographic.
