Similar Weaning Success Rate with High-Intensity and Sham Inspiratory Muscle Training: A Randomized Controlled Trial (IMweanT)
Authors' conclusion
Both high-intensity IMT and sham low-intensity IMT, with high adherence to the protocol, resulted in similar weaning success rates and pronounced improvements in maximal inspiratory muscle strength.
Study context
- Population
- Patients with weaning difficulties
- Comparison
- High-intensity inspiratory muscle training (IMT) vs sham low-intensity IMT
Methodological detailssham-controlled
- Sham-controlled
