This study aimed to examine the impact of family centered, goal-oriented physiotherapy and rehabilitation on body function, activity, participation, and quality of life in severely affected children with dyskinetic cerebral palsy (DCP). The first assessment was conducted and recorded for all patients at the beginning of the study. Subsequently, the study group was taught family centered physiotherapy practices in addition to routine physiotherapy for 10 weeks to be performed at home. The control group only received routine physiotherapy. Weekly remote monitoring, regular meetings, and a second assessment at the 10th week were conducted. The study concluded with all face-to-face assessments. According to the research protocol, the primary aim of this study was to evaluate the effectiveness of a 10-week family centered physiotherapy application. The goal of this intervention was to improve movement and posture, thereby enhancing daily activities and quality of life. The primary endpoint of the study was to determine the impact of family physiotherapy application taught to families during the 10-week education period. This study was conducted at the Faculty of Physical Therapy and Rehabilitation, Hacettepe University. This study aimed to structure and define a family centered, goal-oriented, personalized physiotherapy, and rehabilitation application for the treatment of children with cerebral palsy. One of the significant objectives of this study was to examine the effects of this intervention within the framework of the International Classification of Functioning, Disability, and Health (ICF) on body function, activity, participation, and quality of life.
