Methods and Procedures: Thirty children with cerebral palsy from both sexes were included in this study. The children ages ranged from 3 to 11 years old. Children were evaluated using spirometer to assess forced expiratory volume at first second and peak expiratory flow and gross motor function classification system to assess the functional level.
Aim: To investigate the relation between forced expiratory volume at first second and peak expiratory flow with gross motor function level in the children with cerebral palsy.~Methods and Procedures: Thirty children with cerebral palsy from both sexes were included in this study.
