Children with CP usually have difficulties in mobility, transfer and social participation due to many motor and sensory disorders such as muscle weakness, decreased postural control, balance, spasticity. Abnormal motor patterns and tone, poor trunk control, and postural disorders adversely affect the physical development of these children. Children with CP show deficits in proximal muscle co-contraction and posture stabilization, which leads to limitations in postural reactions and antigravity movements. Dysfunctions are also observed in antisipatory and reactive postural adjustments, and limitations occur especially in upper extremity functions such as walking, reaching, and eating. Although these limitations associated with postural control dysfunctions are known, optimal intervention methods have not yet been determined. Because of these dysfunctions, many individuals with CP have difficulty walking independently, walking on slopes/uneven ground, and performing daily physical functions. Trunk control, which is formed by the activation of the core muscles, is the determinant of postural control, automatic postural reactions, balance, walking and functional activities from the early period.By focusing on the TrAb muscle with Pilates, the stabilization of the trunk muscles can be increased by creating control thanks to the core stabilization training. In addition, the TrAb muscle works together with the diaphragm muscle, which is the main respiratory muscle. The expected increased respiratory capacity with training may also affect hemodynamic responses. Proximal extremity muscles around the hip are also important for maintaining upright posture and maintaining mobility. Studies have shown that hip abductor muscle strength is more associated with gait variables and motor functions in children with CP compared to knee and ankle muscles. Although the importance of this in terms of gait has been determined, studies investigating the activation patterns of trunk and hip muscles during walking of individuals with CP are limited.For this reason, it is thought that pilates training can be applied in terms of muscle strength and postural control in selected individuals with CP who can walk, stand independently, but need to develop some components for controlled movement.Although there are a limited number of studies investigating the effects of modified pilates exercises (MPE) in individuals with CP in different clinical types, their effects on trunk control, core muscle endurance, hemodynamic responses and gait have not been investigated. It is known that most children with CP have significantly lower performance in cardiorespiratory and metabolic tests than their healthy peers.For many of these children, these mobility limitations associated with physical activity adversely affect musculoskeletal and cardiovascular function and increase the risk for secondary medical conditions. Therefore, viable, effective interventions are needed to improve the mobility and cardiorespiratory performance of children with CP. For example, bodyweight supported treadmill training has been used to address these children's walking and fitness goals. However, its routine use in smaller clinics, schools and home settings is often not feasible given the physical requirements associated with helping a child with significant weakness, spasticity or cardiovascular endurance deficiencies keep pace.For this purpose, it is noteworthy that the effects of MPE training targeting the TrAb muscle on gait and hemodynamic responses have not been investigated, especially in children with CP.This study aims to determine the effects of modified pilates exercises (MPE) and traditional neurodevelopmental therapy (NDT-Bobath) on hemodynamic responses in children with CP.
