Pre-operative Inspiratory Muscle Strength Training in Total Joint Surgery

Recruiting now · Not applicable

Conditions studied: Arthropathy of Knee, Arthropathy of Hip, Lower Extremity Fracture, Orthopedic Disorder

In brief

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.
