Introduction: Kinesiophobia is a common symptom associated with high levels of disability and has also been observed in patients with headache. However, the relationship between kinesiophobia and clinical factors in this population is unknown.

Objective: We aimed to investigate the relationship between kinesiophobia and fear of falling, quality of life, and physical activity in children with headache.

Methods: We included 127 children aged 6-18 years with headache complaints in our study. The Tampa Kinesiophobia Scale (TKS) was used to assess kinesiophobia, the International Falls Efficacy Scale (IFSES) was used to assess fear of falling, the International Physical Activity Questionnaire (IPAQ)- short form was used to measure physical activity, and the Quality of Life Scale for Children (QOLS) was used to assess quality of life. A visual analog scale (VAS) was used to assess pain intensity.

Data for this cross-sectional study were collected from a convenient sample of patients aged 6-18 years with headache complaints who presented to a tertiary care pediatric neurology outpatient clinic between April 2022 and April 2023. The sampling size was determined as 88 at the beginning of the study and 127 patients were reached in our study. The inclusion criteria were determined as patients aged 6-18 years with headache complaints who applied to the pediatric neurology outpatient clinic of a training and research hospital, and the absence of any orthopedic, neurological, etc. disease that would prevent physical activity. The exclusion criteria were determined as having communication problems that would not allow evaluation and having a history of additional chronic diseases that would prevent physical activity. All participants filled out a case evaluation form including demographic information, information about headache complaints, and scores of the questionnaire results. Participants completed the Tampa Kinesiophobia Scale (TKS) for kinesiophobia assessment. The TKS consists of 17 questions inquiring about the increase in pain with movement, fear of injury, and avoidance of movement due to pain. The International Fall Efficacy Scale (IFES) used in our study is a questionnaire consisting of 16 questions that provide information about the level of fear of falling during daily life activities. In our study, the visual analog scale (VAS), one of the most commonly used, oldest, and best validated scales, was used to measure pain intensity. The short form of the International Physical Activity Questionnaire (IPAQ)- consisting of seven questions- was used in our study. In the questionnaire, respondents report the duration and frequency of their activities in the previous week. Measuring the quality of life of the individual with psychological tests is important for determining the quality of life of patients before and after treatment, evaluating the effectiveness and side effects of medical interventions, guiding health policies, and conducting medical research. The Quality of Life Scale for Children (QoLSC) is a general quality of life scale that is widely used in research and evaluates the physical and psychosocial experiences of children between the ages of 2 and 18, independent of illness.

• 6-18 years with headache complaints who applied to the pediatric neurology outpatient clinic
• absence of any orthopedic, neurological, etc. disease that would prevent physical activity.

Exclusion Criteria:

• having communication problems
• having a history of additional chronic diseases
