Upper- and lower-limb exercise program for children with cystic fibrosis

Effects of Upper and Lower Limb Exercises on Muscle Strength, Aerobic Capacity and Respiratory Functions in Children With Cystic Fibrosis

NA · Riphah International University · NCT07508904

This program will test whether supervised upper- and lower-limb cycling and resistance exercises improve muscle strength, aerobic capacity, and lung function in children aged 6–18 with cystic fibrosis.

What this trial studies

This randomized clinical trial will enroll clinically stable children aged 6–18 with confirmed cystic fibrosis at pediatric CF centers in Lahore using convenience sampling. Participants will be randomized to supervised upper-limb (arm cycle ergometry) or lower-limb (leg cycle ergometry) exercise programs added to usual physiotherapy care. Primary outcomes include changes in peripheral muscle strength, aerobic capacity (VO2 peak), and pulmonary function/respiratory muscle endurance measured before and after the intervention. Patients who are oxygen- or ventilator-dependent, recently hospitalized or post-surgical, or with significant cardiovascular or orthopedic limitations will be excluded.

Who should consider this trial

Good fit: Children aged 6–18 with a confirmed diagnosis of cystic fibrosis who are clinically stable, able to perform exercise, and have parental/guardian consent are ideal candidates.

Not a fit: Patients who are oxygen- or ventilator-dependent, recently hospitalized or post-surgical, or have major cardiac or orthopedic limitations are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the intervention could improve muscle strength, exercise tolerance, and respiratory function, which may translate into better daily function and reduced pulmonary decline.

How similar studies have performed: Previous pediatric CF research combining aerobic and resistance training has shown modest improvements in VO2 peak, muscle strength, and functional capacity, so the approach has supportive but not definitive evidence.
