Inspiratory Muscle Training: Background
IMT has demonstrated a number of benefits in a wide range of studies, both in healthy subjects and in patients with clinical conditions.
What is it?
- Inspiratory muscle training (IMT) is a technique designed to directly affect functioning of respiratory muscles, which are skeletal in nature and, therefore, amenable to training1
When should it be used?
- IMT can benefit patients with COPD and other conditions involving inspiratory muscle weakness2, 3
- Often reported benefits by several IMT technologies/protocols are:
- Increased inspiratory muscle strength2,4,5,6
- Reduced dyspnoea2,4,5
- Increased exercise performance4,7,8
- Improved quality of life2,4,9,10
