Intercostal mobilization to improve breathing strength and lung function

Effect of Intercostal Mobilization on Respiratory Muscle Strength, Respiratory Function Parameters and Shuttle Walking Test Performance: A Randomized Controlled Study

NA · Abant Izzet Baysal University · NCT07352722

We will test whether gentle intercostal mobilization can improve breathing muscle strength, lung function, and walking performance in healthy sedentary adults aged 18–30.

What this trial studies

This is a prospective, randomized, controlled, double-blind study enrolling 90 healthy but sedentary volunteers aged 18–30, randomized into intercostal mobilization, sham mobilization, or rest groups (30 per group). Baseline measures include a sociodemographic form, Sedentary Behavior Questionnaire, pulmonary function tests, respiratory muscle strength (MIP/MEP), and the Incremental Shuttle Walking Test. Participants receive the assigned intervention and then repeat pulmonary function, respiratory muscle strength, and the shuttle walking test after the intervention. The design compares real manual intercostal mobilization to a sham and a no-treatment control to isolate any immediate effects on respiratory mechanics and performance.

Who should consider this trial

Good fit: Healthy adults aged 18–30 with a sedentary lifestyle who have no neurological, orthopedic, or cardiopulmonary conditions and are willing to participate are the intended participants.

Not a fit: People with existing cardiopulmonary, neurological, or orthopedic diseases that affect breathing, older adults, or those who are physically active were excluded and are unlikely to experience benefit from these specific results.

Why it matters

Potential benefit: If successful, the approach could provide a simple hands-on technique to boost chest mobility, respiratory muscle strength, and short-term exercise performance, and inform use as a complementary therapy for breathing problems.

How similar studies have performed: Some small trials and case reports suggest manual thoracic techniques can modestly improve chest mobility and lung function, but high-quality randomized evidence remains limited.
