Balance is one of the fundamental components of motor control and plays an essential role in performing daily and sports-related activities. It results from a complex interaction among sensory, motor, and central nervous system processes. Maintaining static balance requires the integration of visual, vestibular, and proprioceptive information and its processing at different levels of the brain. In this process, the cerebral cortex, particularly sensorimotor areas, plays an important role in regulating appropriate responses to maintain postural stability.



The foot, as the body’s primary base of support, also has a significant influence on balance control. Structural abnormalities of the foot can affect balance by altering force distribution, movement patterns, and sensory input. Flexible flatfoot is one of the most common foot abnormalities and is characterized by a reduced medial longitudinal arch during weight-bearing. This condition may be associated with increased postural sway and reduced efficiency of balance control.



Although numerous studies have investigated the effects of corrective exercises on biomechanical characteristics and balance performance, the neural adaptations resulting from these exercises have received less attention. Given the importance of balance and the potential role of corrective exercises in promoting neural adaptations, examining brain activity in individuals with flexible flatfoot may provide a better understanding of the relationship between biomechanical changes and neural responses. Therefore, the present study aims to compare brain activity before and after a period of corrective exercises during static balance in individuals with flexible flatfoot.
