In patients with cerebral palsy, motor loss and changes in muscle tonus significantly affect the movement system including hip, knee, and foot, and cause functional deficiencies. Timely diagnosis of the affected muscle structures and joints can enable us to recover some of the functions lost over time. Well done physical examination could provide us knowledge of the main pattern causing these deformities. In this way, it is possible to collect information about the process of the disease, and prevent potential problems.
