Run by Izmir Democracy University · NCT06984679 · Data updated 2026-11-12

This project will compare breathing difficulty, exercise capacity, muscle strength, bladder control, and quality of life in children aged 6–18 with cystic fibrosis versus healthy peers to see where support is needed.

Is this trial a fit for you?

Likely a good fit

Children and adolescents aged 6–18 with a confirmed diagnosis of cystic fibrosis who are clinically stable for at least three weeks and able to cooperate with testing are ideal candidates.

Probably not a fit

Children who are not clinically stable, have recent orthopedic, neurological, psychological, or cardiovascular problems, cannot cooperate with tests, or are current/former smokers are unlikely to be included or to benefit from this protocol.

What this trial studies

This observational study compares dyspnea, functional capacity, muscle strength, urinary incontinence, and quality of life between children and adolescents with cystic fibrosis and age- and gender-matched healthy peers. Participants aged 6–18 will undergo clinical evaluations, exercise tests, physical measurements, and standardized questionnaires. Data will be collected at Izmir Democracy University and analyzed to identify differences in physical impairments and symptom burden. Results are intended to inform health management and rehabilitation priorities for children with cystic fibrosis.

Why it matters

Potential benefit: If successful, the findings could identify specific physical or symptom areas to target with therapy and rehabilitation to improve daily functioning and quality of life for children with CF.

How similar studies have gone: Previous observational studies have reported reduced exercise capacity and muscle strength in children with CF and have helped guide rehabilitation, so the basic approach is established though local data may be limited.
