Abstract: Compared with normal children,the children with cerebral palsy are different in respiratory movement and respiratory function,showing a less concordant in respiratory muscles,abnormal thoracic cage,disturbance in ventilation and air exchange,decreased compliance,changed distribution in muscle fiber types,and so on.Dynamic and static lung volumes have also changed.Pronunciation and oxygen uptake are involved for the respiratory disturbance too.Hydrotherapy is an effective training in improving respiratory function,proper temperature can reduce respiratory muscular tension,hydrostatic pressure provides extensive stimulation of the exteroceptors and proprioceptors.This is expected to improve coordination,respiration,and related functions such as eating and speaking.

Key words: children, cerebral palsy, respiration, hydrotherapy, review
