Since the gastrocnemius muscle crosses both joints, the joint kinematics of the ankle are affected by knee flexion. According to the Kendall \& McCreary assessment of normal joint motion angles, the generally accepted normal range of motion for ankle dorsiflexion is 20° when the knee joint is in extension and can approach 30° when the knee joint is flexed due to relaxation of the gastrocnemius. In the mid-stance phase of gait, it is observed that the ankle joint allows 8-10° dorsi flexion movement. In this study, a minimum 13° increase in dorsiflexion with knee flexion compared to dorsiflexion with knee extension will be considered as isolated gastrocnemius muscle tightness. Isolated gastrocnemius muscle tightness has been associated with many biomechanical changes such as pes planus, talar equinus, hindfoot pronation and symptoms such as plantar fasciitis, leg pain, metatarsalgia, achilles tendinopathy by compensatory effects on the lower extremity and foot during gait. The association of increased hindfoot pronation with isolated gastrocnemius tightness has been shown in many studies. Regardless of the etiology of pronation of the hindfoot, there will be adaptive isolated gastrocnemius tightness with talar plantar flexion. Isolated gastrocnemius tightness, which causes plantar flexion in the ankle joint and pronation in the subtalar joint, also prevents the distribution of the load to the base of the foot within normal limits during weight bearing. However, no study investigating the effect of physiotherapy program on function and gait has been encountered. The aim of this study was to investigate the effect of a physiotherapy program on lower extremity function and gait in children with isolated gastrocnemius muscle tightness.
