What this trial studies

This observational study aims to evaluate and compare respiratory muscle strength, endurance, and core muscle endurance in children diagnosed with cystic fibrosis (CF) against healthy peers. By measuring various aspects of muscle endurance, including core and peripheral muscle endurance, the study seeks to understand the impact of CF on muscle function and overall physical capacity. The study includes children aged 6-18 years, with specific inclusion and exclusion criteria to ensure accurate assessments. The findings could provide insights into the physical challenges faced by children with CF and inform future interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 6-18 diagnosed with cystic fibrosis and having a forced expiratory volume in one second (FEV1) above 40% of the predicted value.

Not a fit: Patients who may not benefit from this study include those with orthopedic, neurological, or vestibular issues that affect assessment methods, or those with a history of recent exacerbations or organ transplants.

Why it matters

Potential benefit: If successful, this study could enhance understanding of muscle endurance in children with cystic fibrosis, potentially leading to improved management strategies and interventions.

How similar studies have performed: While some studies have compared respiratory and lower extremity muscle endurance in children with CF, this specific focus on core muscle endurance is novel and has not been previously evaluated.
