What this trial studies

This study evaluates the effects of preoperative inspiratory muscle training (IMT) on breathing function in patients undergoing total joint arthroplasty or lower extremity orthopedic surgery. Participants will be randomized into three groups: those completing daily IMT, those receiving a single acute IMT session before surgery, and those receiving standard surgical care. The study aims to determine if preoperative IMT can reduce post-operative declines in breathing function and minimize pulmonary complications. Assessments will be made before surgery and during the first 24 hours post-operation to evaluate outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older with a history of tobacco use or risk factors for post-operative pulmonary complications.

Not a fit: Patients with severe pre-existing respiratory conditions or those requiring continuous supplemental oxygen may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance recovery and reduce complications related to breathing after orthopedic surgery.

How similar studies have performed: Previous studies have shown that inspiratory muscle training can reduce complications in cardiac surgeries, suggesting potential benefits in orthopedic settings, though this specific application is novel.
