Inspiratory Muscle Training for Total Joint Surgery

This study is looking at whether breathing exercises before orthopedic surgery can help improve your breathing and recovery. We know that breathing can be harder for a few days after surgery. This study will test if doing daily Inspiratory Muscle Training (dIMT) for 2-4 weeks before surgery, or a single session of Acute Inspiratory Muscle Training (aIMT) right before surgery, helps compared to standard care. We'll measure your breathing strength (Maximal Inspiratory Pressure) and lung capacity (Forced Vital Capacity) 24 hours after surgery to see if these exercises make a difference. You might be able to join if you are 18 to 100 years old and have certain risk factors for breathing problems after surgery, like a history of tobacco use or a lung condition. The current status of this study is unclear.

Study design
This is a randomized pilot study with 36 participants. Participants will be assigned by chance to one of three groups: daily Inspiratory Muscle Training, acute Inspiratory Muscle Training, or standard care.
What's involved
Participants will either do daily breathing exercises for 2-4 weeks before surgery, a single breathing exercise session right before surgery, or receive standard care. Breathing function will be checked before surgery and 24 hours after surgery.
Compensation
Not stated in the trial record.
Follow-up
Breathing function will be monitored through the first 24 hours after surgery.
