The purpose of this research study is to evaluate effects of respiratory strengthening exercises on breathing function, in people who have orthopedic surgery. It is known that breathing function decreases for a few days after surgery. in In this study, we want to see if exercising before surgery strengthens the breathing muscles and improves recovery after surgery.
Preoperative inspiratory muscle training (IMT) has been shown to reduce post operative complications (PPC's) following prolonged cardiac surgeries, but its potential benefits have not been investigated in shorter surgeries with expected brief post-operative hospitalizations. We intend to address this unmet need by investigating preoperative IMT, an evidence-based rehab strategy to optimize lung function, prior to total joint arthroplasty surgery. The fundamental hypothesis guiding this proposal is that preoperative IMT will attenuate post-operative declines in breathing function and offset PPC…
