Trial Summary

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Inspiratory Muscle Training for Orthopedic Surgery Recovery?

Inspiratory muscle training (IMT) has shown potential benefits in improving respiratory muscle strength and endurance, particularly in patients with respiratory muscle weakness, as seen in studies involving chronic obstructive pulmonary disease (COPD) and lung surgery. Additionally, IMT has been found to improve oxygenation and reduce complications in high-risk patients after lung cancer surgery.12345

Is inspiratory muscle training safe for humans?

Inspiratory muscle training (IMT) has been used safely in various conditions, including for patients with prolonged mechanical ventilation and those with pulmonary diseases. While the effectiveness can vary, no significant safety concerns have been reported in the studies available.12367

How is the treatment Inspiratory Muscle Training (IMT) unique for orthopedic surgery recovery?

Inspiratory Muscle Training (IMT) is unique because it focuses on strengthening the muscles used for breathing, which can help improve overall respiratory function and physical performance. This approach is different from typical orthopedic recovery treatments that may not specifically target respiratory muscles.12358

Eligibility Criteria

This trial is for adults over 18 who have smoked or currently smoke, may have lung disease, and are undergoing orthopedic surgery. They should be able to do breathing exercises and report any issues like pain. People with severe lung obstruction, very poor health status, recent serious infections, oxygen dependency, certain neurological conditions or those in pulmonary rehab can't join.

Treatment Details

Interventions

  • Acute Inspiratory Muscle Training (aIMT)
  • Daily Inspiratory Muscle Training (dIMT)
  • Standard of Care (SOC)
Trial OverviewThe study tests if pre-surgery breathing exercises (acute or daily) can improve recovery compared to standard care in patients having joint surgery. It aims to see whether these exercises before surgery help strengthen the respiratory muscles and enhance postoperative breathing function.
Participant Groups
3Treatment groups
Experimental Treatment
Active Control
Group I: Daily IMT (dIMT)Experimental Treatment1 Intervention
IMT (inspiratory muscle training) is a treatment strategy aimed to strengthen the muscles of inspiration, the diaphragm and external intercostals, by increasing their force-generating capacity. Participants in the dIMT (daily IMT) will complete daily inspiratory training exercises 2-4 weeks prior to surgery. A pressure threshold training device containing an adjustable-tension spring to provide resistance during inspiration will be used. Subjects will complete 5 sets of 5 maximal volume and speed breaths daily at a pressure 70% of MIP and will rest 1 minute between sets. They will be asked to keep a log to track their sessions to evaluate compliance with the exercise regimen.
Group II: Standard of Care (SOC)Active Control1 Intervention
The SOC group will receive the usual surgical standard of care only.
Group III: Acute IMT (aIMT)Active Control1 Intervention
Patients in the aIMT (acute IMT) experimental group will complete a single session of IMT guided by a physical therapist within 30 minutes of anesthesia induction in addition to standard of care. The adjustable pressure threshold training device to provide resistance during inspiration will be used. Subjects will complete 5 sets of 5 maximal volume and speed breaths, and rest 1 minute between sets. The training intensity will be set at 70% of MIP.

Findings from Research

Inspiratory muscle training (IMT) combined with pulmonary rehabilitation (PR) did not show significant improvements in dyspnea, functional exercise capacity, or health-related quality of life in COPD patients, based on a review of 55 randomized controlled trials involving 4,467 participants.
However, IMT alone may lead to better outcomes in these areas, suggesting that while IMT can be beneficial, its effectiveness may be diminished when combined with PR.
Inspiratory muscle training, with or without concomitant pulmonary rehabilitation, for chronic obstructive pulmonary disease (COPD).Ammous, O., Feki, W., Lotfi, T., et al.[2023]
A study involving 40 critically ill patients showed that using an electronic device for inspiratory muscle training (IMT) was feasible, with 81% of planned sessions completed, indicating good adherence to the intervention.
The electronic IMT was found to be safe, with no major adverse events and only 10% minor adverse events that were transient and without clinical consequences, while over 85% of participants reported it as helpful for their recovery.
Feasibility, safety, and patient acceptability of electronic inspiratory muscle training in patients who require prolonged mechanical ventilation in the intensive care unit: A dual-centre observational study.Nickels, M., Erwin, K., McMurray, G., et al.[2023]
Inspiratory muscle training (IMT) improves the strength and endurance of inspiratory muscles, reduces dyspnoea during daily activities, and enhances quality of life, but does not offer additional benefits when combined with standard pulmonary rehabilitation programs.
IMT is beneficial for patients who cannot engage in full exercise training, and it shows promise in pre-operative programs, suggesting it may be a useful intervention in specific contexts.
