Chronic non-progressive encephalopathy (CNE), also known as cerebral palsy, is a disorder of movement and posture resulting from non-progressive damage to the immature or developing brain, which causes clinical manifestations (BAX et al., 2005). Aquatic physiotherapy is a physiotherapeutic resource that contributes to the treatment of patients with NPC, as it improves balance, motor coordination, temporal and spatial orientation, gait, muscle flexibility and social function. There is a need for studies with a larger number of homogeneous patients, control and experimental groups with statistical significance tests and treatments of choice for improving these aspects in these patients.
