RESUMO:

Age-related structural and functional changes in the foot may explain the biomechanical alterations, particularly, in the lower extremity distal powers during gait. Triditionally, these distal powers have been estimated through inverse dynamics approach where the human segments, including the foot, are considered rigid bodies and the foot-and-ankle complex is modelled considering only the 3 rotational degrees of freedom. However, it is well-known that the foot deforms during gait and, thus, adopting it as a rigid body consists of a methodological limitation that challenges the clinical application of the results of previous studies. To overcome this limitation, some studies have recently proposed simplified methods where the foot is considered a deformable elemento. However, these studies have examined only young individuals and, to our knowledge, no studies have applied these methods in older individuals. Therefore, the aim of this study was to apply these diferent methods to estimate the power of the foot-and-ankle complex during gait in young and older individuals. These methods address the deformation of the foot and the translational degrees of freedom in the foot-and-ankle complex during gait that are typically ignored in previous studies that investigated age-related gait biomechanics. To apply the methods, we used kinematic and kinetic data of 4 individuals (2 young and 2 older) from a previously published public data set. In agrément with previous studies, the preliminary results demonstrated correspondence across different methods to estimate power. Moreover, the presente results indicate that aging reduces the distal lower extremity power during walking when young and older subjetcs are compared. The employed methods and the presented results may be reproduced using the Jupyter notebook and raw data available in the Github repository. A more throughful analysis will be performed, considering a large number of young and older subjetcs to provide conclusive findings.
