Comparing lung function and exercise ability in children with hemophilia and healthy peers

Comparison of Pulmonary Function, Exercise Capacity, and Physical Activity Level Between Children with Hemophilia and Healthy Controls

Observational Hacettepe University · NCT06636565

This study looks at how hemophilia affects lung function and exercise ability in children compared to their healthy peers to better understand the importance of physical activity for them.

What this trial studies

This observational study aims to compare pulmonary function, exercise capacity, posture, and physical activity levels between children diagnosed with hemophilia and healthy controls. It focuses on understanding how hemophilia affects physical activity and respiratory mechanics, which may be influenced by chronic pain and joint issues. The study will involve children aged 8-18 who are clinically stable and on prophylaxis treatment, assessing their ability to cooperate with various tests. The findings could provide insights into the importance of exercise for children with hemophilia.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 8-18 with a diagnosis of hemophilia who are clinically stable and on prophylaxis treatment.

Not a fit: Patients who are inhibitor positive, have a history of acute joint or intramuscular bleeding, or severe cardiovascular, orthopedic, or neurological issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the physical capabilities of children with hemophilia, potentially leading to improved management and encouragement of physical activity.

How similar studies have performed: While there may be limited studies directly comparing these specific parameters in children with hemophilia, the approach of assessing exercise capacity and pulmonary function is supported by existing literature on the benefits of physical activity in chronic conditions.
