The present research has identified that the work Quality of life of parents of children with cerebral palsy is a cross-sectional design with a control group. It is not experimental in the sense that cerebral palsy is inflicted on the subjects. Instead, a post-test study is apparent, where the post-results of the effects of having cerebral palsy are examined. The authors wanted to know the differences and similarities in the quality of life conditions between parents with children who have cerebral palsy and parents who have healthy children. The authors chose the right research design because they aimed to know how cerebral palsy affects the parents, instead of children with cerebral palsy per se. The author has rightly presented that through the comparative approach, they can determine these differences and similarities and make deductions from the data. Sample Size: 40 parents of children with cerebral palsy aged 6-17 years. The control group was composed of 40 parents of healthy children (27 mothers and 13 fathers). Sample characteristics: They are parents of children with cerebral palsy aged 6-17 years. These children were treated at the Department of Pediatric Rehabilitation of the Medical University of Bialystok. Their cerebral palsy conditions are as follows: spastic tetraplegia – 18 (45%), spastic hemiplegia (hemiplegia spastica) -15 (37.5%), spastic diplegia (diplegia spastica) -7 (17.5%).
