A Comparative Biomechanical Analysis during Planned and Unplanned Gait Termination in Individuals with Different Arch Stiffnesses

Although values of arch stiffness index (ASI) have been used to evaluate structure and injury susceptibility, investigations are limited regarding the influence ASI on biomechanical characteristics during gait termination, which involves a challenging balance transition from walking standing. This study aimed explore plantar pressure distribution lower extremity joint kinematic differences between individuals with both stiff flexible (SA FA, respectively) planned unplanned termination (PGT UGT, respectively). Following calculation ASI, sixty-five asymptomatic male subjects were classified participated in two types tests acquire data. Parameters compared SA FA using two-way ANOVA PGT respectively. UGT was found larger range motion hip sagittal plane knee transverse when PGT. The limb joints caused by difference mainly concentrated ankle metatarsophalangeal joints. Plantar data, represented maximum pressure, showed significant forefoot rearfoot areas. These results suggest that could change freedom joints, tends conduct compensatory adjustment for kinetic chain. An understanding structures may provide additional insights into foot function prediction termination.
