Abstract

Foot misalignments, such as forefoot varus (FV), have been associated with musculoskeletal injuries in the proximal joints of the lower limb. Previous theories suggested that this association occurs because FV influences knee and hip kinematics during closed kinetic chain activities. However, research on the effects of FV in the kinematics of the lower limb is very scarce. Therefore, the purpose of this study was to compare the knee and hip kinematics between subjects with and without FV during a functional weight-bearing activity. Forty-six healthy adolescents were divided into two groups: group of subjects with FV (VG, n = 23) and group of subjects with aligned forefoot (CG, n = 23). A kinematic evaluation was conducted while the subjects performed a single-leg squat task. The variables of interest were hip internal rotation and adduction and knee abduction excursions at 15°, 30°, 45° and 60° of knee flexion. Between-group comparisons were performed with multivariate analysis of variance. Results showed that the VG presented greater hip internal rotation when compared with the CG across all evaluated knee flexion angles (P = 0.02-0.0001). No differences between groups were observed in hip adduction or knee abduction (P > 0.05). These results indicate that FV influences the transverse plane hip movement patterns during a functional weight-bearing activity. Considering that excessive hip internal rotation has been associated with knee injuries, these findings might contribute for a better understanding of the link between FV and injuries of the proximal joints of the lower limb.

Efecto del varo de antepié en la cadera y rodilla

Una mecánica del pie alterada se asocian con lesiones de la columna lumbar, la cadera, la rodilla y la pantorrilla. Este estudio investigó el efecto del varo de antepié (resultante de la relación entre las cabezas de los metatarsianos supinadas y la parte trasera del pie) en la cinemática de la cadera y de la rodilla durante la sentadilla a una pierna.

El varo de antepié (VA) aumenta la pronación de la articulación subtalar para permitir que las cabezas de los metatarsianos mediales se contacten con el suelo. Los autores encontraron que los sujetos con VA demostraron una mayor rotación interna de la cadera durante la sentadilla a una pierna en comparación con los sujetos con un pie neutral. No hubo ningún efecto sobre la posición de la rodilla o de la aducción de la cadera.

La evaluación de la posición del antepié en relación con el retropié puede estar indicada en pacientes con dolor en las articulaciones de la cadera, sobre todo los que presentan síntomas de pinzamiento.
