Evaluation of Sleep Quality and Caregiver Burden in Children With Cerebral Palsy

Cerebral palsy (CP) is the most common cause of motor disability in childhood and often requires long-term daily care provided by family members. Sleep disorders are highly prevalent in children with CP compared with typically developing peers and are frequently associated with spasticity, seizures, pain, and behavioral issues. Poor sleep may further compromise the child's functional capacity and quality of life. At the same time, caregivers of children with CP often face increased physical and psychological demands, including high levels of stress, anxiety, and depression, which may be exacerbated by poor sleep quality and increased caregiving burden.

Although prior studies have investigated these factors separately, there is limited research examining the combined relationship between child sleep quality, functional status, caregiver sleep quality, caregiver burden, and psychological health. A comprehensive evaluation of these interrelated aspects may help in identifying high-risk groups and developing supportive interventions for both children and caregivers.

This single-center, observational, cross-sectional study will be conducted in the outpatient Physical Medicine and Rehabilitation clinics of Istanbul Physical Medicine and Rehabilitation Training and Research Hospital. The study will recruit at least 100 child-caregiver pairs. Children aged 2-18 years with a confirmed diagnosis of CP and their primary caregivers (aged ≥18 years) will be included. Sampling will be based on convenience and voluntary participation.

Data collection will include standardized questionnaires and clinical classifications. For children, sleep quality will be assessed using the Children's Sleep Habits Questionnaire (CSHQ), while functional levels will be determined by the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS). Spasticity will be evaluated with the Modified Ashworth Scale. For caregivers, sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), caregiver burden with the Zarit Burden Interview (ZBI), and psychological status with the Hospital Anxiety and Depression Scale (HADS).

All assessments will be performed by trained researchers through face-to-face interviews following standardized protocols. Data will be analyzed using descriptive statistics, correlation tests, and multivariable regression analyses to explore the associations between child sleep quality, caregiver sleep quality, caregiver burden, and psychological outcomes.
