Functional strengthening exercises have been proven to be effective in patients with spastic cerebral palsy. However, which exercise is the most effective is unknown. The aim of this study is to examine the effectiveness of three different progressive functional exercise programs in children with unilateral and bilateral spastic cerebral palsy.

Children with Cerebral Palsy have weakness in thier muscles due to cortical lesions leading to deficiencies in motor control, balance and functional abilities. All children with Cerebral Palsy have shown to present with foot and ankle disorders; the ankle dorsi and plantar flexor muscles are both problematic; the plantarflexors are usually spastic and the dorsiflexors are usually not active enough and usually these muscle problems lead to problems in the childrens' gait abilities. When rehabilitation programs are examined, the results of exercises addressing these problems do not have precise answers. Functional strengthening exercises have been proven to be effective in patients with spastic cerebral palsy. However, which exercise is the most effective is unknown. Which muscle goup has the most effect on gait, balance and functional activities is still unclear. Therefore, the investigator's aim in planning this study is to examine the effectiveness of three progressive functional exercise programs in children with unilateral and bilateral spastic cerebral palsy.
