Resumen

The aim of this study was to determine the impact of the forefoot varus (FV) on the kinematics of the lower limb, in standing and during walking, in a group of children aged between 7 and 10 years. The Oxford Foot Model was used, simultaneously with a conventional lower limb model, to compare the kinematics of 10 forefoot varus children (9.3 ± 1.7 years; 6.1º ± 2.3º of FV) and 11 healthy controls (9.2 ± 1.6 years). Data acquisition was performed using a six-camera motion capture system. The independent t- test was used to compare normal data and the Mann-Whitney test to compare non-normal data. In standing, the FV group showed a higher hindfoot eversion, a lower height of the internal longitudinal arch and a higher flexion in the 3 main joints of the lower limb. During walking, this group presented a higher hindfoot eversion and a lower height of the internal longitudinal arch in all the studied phases; on the other hand, a higher pelvis anterior tilt, a higher flexion of the 3 main joints of the lower limb and a higher external rotation of the hip were found. There were no differences in the gait speed but, to achieve this speed, the FV group needed a higher cadence, due to a lower length and duration of the step.
