摘要

BackgroundPronated foot is one of the most important factors that may lead to musculoskeletal injuries of the lower extremities. It is known that in a pronated foot, excessive mechanical loads are applied to the lower limb structures, which result in the altered foot biomechanics, including vertical ground reaction forces (VGRFs) and rate of loading (ROL). Therefore, the aim of this study was to determine the changes in foot kinetic parameters in the pronated compared to the normal foot structures. MethodsIn this cross-sectional study, 15 individuals (mean age of 23.27?±?3.28 years) with asymptomatic pronated feet and 15 normal subjects (mean age of 23.40?±?3.11 years) were recruited from both genders by using a simple non-random sampling method. VGRF, ROL, and the resultant vector of time to stabilization (RVTTS) were evaluated during the forward jump landing task by using a force plate. ResultsThe findings showed that the following parameters were significantly higher in the group of pronated feet than in the normal subjects: VGRF (3.30?±?0.17 vs. 2.81?±?0.15,p?=?.042), ROL (0.10?±?0.01 vs. 0.07?±?0.006,p?=?.020), and RVTTS (2592.80?±?141.24 vs. 2114.00?±?154.77,p?=?.030). ConclusionAll the measured foot kinetic parameters were higher in the pronated foot subjects than in the normal participants. An impaired movement control and greater forces imposed on the foot region of the pronated foot, compared to the normal foot individuals, were discovered indicating the former group's possible increase of susceptibility to various musculoskeletal injuries.
