In the study we planned, 42 individuals diagnosed with cerebral palsy will be divided into 2 groups according to age groups. Individuals aged 4-11 will be included in the child group, and individuals aged 12-18 will be included in the adolescent group. Individuals with cerebral palsy in the child and adolescent group will also be randomized and divided into treatment and control groups. In addition to the conventional treatment created in accordance with neurodevelopmental treatment approaches, video-based virtual reality games will be played for a total of 10 weeks for treatment groups in both age groups. The patients will be followed up with a video-based game application for an average of 20 minutes, after the physiotherapy and rehabilitation application, which consists of an average of 45 minutes, twice a week. Individuals in the control group in both age groups will be followed for 10 weeks with conventional treatment created in accordance with neurodevelopmental treatment approaches.

The entire sample will be evaluated at the beginning of the study and at the end of the 10th week. Our main aim in the study is to compare the effects of video-based games applied in different age groups on balance, trunk proprioception, motivation and quality of life.

A total of 42 patients with cerebral palsy who agreed to participate in the study, 22 patients between the ages of 4-11 and 22 patients between the ages of 12-18, will be included. Parents of the patients will be informed about the study.

42 individuals diagnosed with cerebral palsy will be divided into 2 groups according to age groups. Individuals aged 4-11 will be included in the child group, and individuals aged 12-18 will be included in the adolescent group. Individuals with cerebral palsy in the child and adolescent group will also be randomized within themselves and divided into treatment and control groups. In addition to conventional treatment created in accordance with neurodevelopmental treatment approaches, video-based virtual reality games will be played for a total of 10 weeks for treatment groups in both age groups. The patients will be followed up with an average of 20 minutes of video-based games, after the physiotherapy and rehabilitation application, consisting of an average of 45 minutes, twice a week. Individuals in the control group in both age groups will be followed for 10 weeks with conventional treatment created in accordance with neurodevelopmental treatment approaches.

A treatment plan will be created for the entire sample group according to neurodevelopmental treatment approaches. In the content of the treatment plan; In order to regulate muscle tone and increase sensory input, intramuscular stretching and soft tissue mobilization, exercises that improve protective, balance and correction reactions, and support the development of postural control will be included. In addition, studies aimed at ensuring proper posture and increasing body awareness during standing without support, facilitation of trunk extension will be carried out. For the development of postural control in the same position, facilitation of trunk elongation and weight transfer to the affected and less affected side will be emphasized. Exercises will be performed on stepping and descending from the affected and less-affected side. Supported with appropriate hand grips, forward jumping with two feet, one foot, and weight transfer on one foot will be carried out.

In the evaluation of the patient, the pediatric motivation scale, balance, trunk proprioceptive sense and quality of life will be evaluated at the 1st and 10th weeks.
