RESUMO

Idiopathic clubfoot is the most prevalent congenital deformity in orthopedics. Locomotion studies in children with such a deformity can help towards better rehabilitation. The aim of this study was to analyze the gait and countermovement jump biomechanics, and to describe the perception threshold in children with congenital clubfoot who have been surgically treated. For data analysis, non-parametric statistical tests were applied. Changes in plantar sensitivity were not found. Despite similar force, kinematics, and electromyography curves along groups, it was found differences for some biomechanical variables. For gait, children with clubfoot showed higher vertical force increase to the first peak. At midstance, they showed higher knee flexion and ankle dorsiflexion, and lower vertical force. At toe off, they presented lower anterior-posterior force, second vertical force peak, and plantar flexion. For jump, during the preparation phase, they presented smaller dorsiflexion; during propulsion, they showed larger knee flexion and smaller plantar flexion, vertical force and m medial gastrocnemius activity. In landing, there was a higher vertical force growth rate, less plantar flexion, and larger knee flexion. The understanding of how the locomotion system work contributes to choose the best stimuli to be applied during physical activity for those children
