PBMT with a pulmonary rehab program for COPD patients

Official title: Photobiomodulation Therapy (PBMT) Associated With a Pulmonary Rehabilitation Program on the Functional Capacity of Patients With Chronic Obstructive Pulmonary Disease (COPD): a Randomized, Placebo-controlled, Double-blind Clinical Trial.

Run by Federal University of Health Science of Porto Alegre · NCT07878884 · Data updated 2026-11-12

A small randomized trial tests whether adding photobiomodulation therapy before exercise in a COPD pulmonary rehab program helps improve functional capacity.

Is this trial a fit for you?

Likely a good fit

Adults with COPD in the maintenance phase (GOLD 3-4) who can walk.

Probably not a fit

Patients unable to walk or with exclusion criteria (e.g., recent MI, uncontrolled hypertension, implanted pacemaker/defibrillator) may not benefit.

What this trial studies

This randomized, double-blind, placebo-controlled trial investigates whether photobiomodulation therapy (PBMT) added to a standard pulmonary rehabilitation program improves functional capacity in COPD patients. Twenty participants with moderate-to-severe COPD are assigned to active PBMT or placebo, receiving treatments before the rehab exercises over eight weeks (16 sessions total). The study keeps the rehab protocol identical for all participants and uses sham PBMT in the control group. Primary outcomes focus on functional capacity, with eligibility limited to adults with COPD in the maintenance phase who can walk. The trial is conducted at Santa Casa de Porto Alegre with sponsorship from the Federal University of Health Science of Porto Alegre.

Why it matters

Potential benefit: If successful, PBMT could enhance the benefits of pulmonary rehabilitation for COPD patients.

How similar studies have gone: Prior work shows PBMT can improve muscle performance and reduce fatigue in various populations; results in COPD populations are still emerging.
