Thoracoabdominal rebalancing for better breathing after coronary bypass
Official title: Acute Effect of the Thoraco-abdominal Rebalance Method on Diaphragmatic Function, Respiratory Discomfort, Pulmonary Complications and Hemodynamic Variables in Postoperative Cardiac Surgery Patients: Randomized Clinical Trial
Run by Instituto de Cardiologia do Rio Grande do Sul · NCT06814951 · Data updated 2026-11-12
This study will try the thoracoabdominal rebalancing (TAR) method versus standard physiotherapy to see if it improves diaphragmatic movement and lung function in adults over 35 after coronary artery bypass surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are hemodynamically stable adults over 35 who underwent CABG within the past 24 hours and have a prescribed postoperative physiotherapy plan.
✕Probably not a fit
Patients who were intubated or on mechanical ventilation for more than 12 hours, or who require non-invasive ventilation before or during the study period, are unlikely to benefit from this protocol.

What this trial studies
This randomized, single-blind trial enrolls adults older than 35 who are hemodynamically stable within 24 hours after coronary artery bypass grafting and who have a prescription for postoperative physiotherapy. Participants are randomized to receive either the thoracoabdominal rebalancing (TAR) method or conventional physiotherapy. Outcomes include diaphragmatic ultrasound and pulmonary spirometry, plus vital signs, respiratory distress scales, and postoperative pulmonary complications. The trial excludes patients intubated or on mechanical ventilation for more than 12 hours or requiring non-invasive ventilation, and is conducted at the Cardiology Institute of Rio Grande do Sul in Porto Alegre.
Why it matters
Potential benefit: If successful, TAR could improve diaphragmatic movement and lung function after CABG, reducing short-term respiratory complications and speeding recovery.
How similar studies have gone: Diaphragmatic ultrasound and targeted physiotherapy have shown benefits in other surgical populations, but specific evidence for the TAR method after CABG is limited and relatively novel.

Inclusion Criteria: * Individuals over 35 years of age who undergo coronary artery bypass graft surgery with prescribed physiotherapy treatment will be included in the study. Exclusion Criteria: * Patients who are intubated and/or have remained on mechanical ventilation for more than twelve hours, or who require non-invasive mechanical ventilation (NIV) before or during the collection period will be excluded.
