The lower extremity consists of sequent columns. The deviation of one segment from its normal alignment in the lower extremity also affects the alignment of the other segments. The alignment of the parts of the foot during weight bearing is called foot posture. Foot posture is divided into neutral, pronation, and supination. Foot posture varies significantly from person to person, and deviations from normal foot posture are associated with lower extremity injuries. Increased or prolonged pronation has been identified as both a risk factor and etiologic factor for increased navicular drop, a lower extremity malalignment pattern. In pronation posture, the foot may not adequately adapt to the ground, and there is increased movement of the lower extremity in the frontal plane. As a result, the person's postural stability is compromised. The fact that the foot is the most distal segment of the lower extremity chain indicates that even small biomechanical changes in the bearing surface can significantly affect postural control strategies. There are studies in the literature that examine the effect of foot pronation on dynamic balance and postural stability in individuals with different foot postures. However, to our knowledge, there is no study that examines differences in postural stabilization and lower extremity alignment by classifying individuals with varying degrees of subtalar joint pronation into pronation and hyper pronation groups.
