What is the difference between resistive and threshold devices?
With a threshold device, you have to overcome an initial pressure to open a valve, and that’s the target pressure.
Once the valve is opened, there is no resistance to the airflow anymore.
The difference between resistive devices like The Breather is that the resistance that your muscles are working against is constant throughout the entire breath cycle, so your inspiratory and expiratory muscles are working for the entire 2 to 3 seconds during inhale and during exhale. This puts a more sustained workload on the muscles.
On a study commissioned by Dr. Watts of Texas Christian University, they confirmed considerable muscle activation using sEMG during both inspiration and expiration through The Breather. Texas Christian University Clinical Study (Poster) https://www.pnmedical.com/clinical-trials/hyolaryngealmuscleactivation/. Direct comparisons between both methods have shown that both threshold and resistive devices strengthen the respiratory muscles, but that the curve of activation looks different, confirming this sustained muscle activation with resistive devices such as the Breather.

How does the Breather differ from a threshold device?
Threshold devices are dominating the scientific literature and the market, while resistive devices were initially lacking clinical evidence. However, clinical evidence for resistive devices is accumulating now, and head-to-head comparisons are ...
What are the differences between each of the devices?
The Breather (the blue and white device that you may have seen) is the original device. This device and the companion resources target adults and children with Respiratory Muscle Weakness. Breather Fit (black and orange device) generates higher ...
What is the difference with this and the inspiratory muscle trainer?
The primary difference is that The Breather is both an inspiratory and expiratory muscle trainer. The combination of both IMT and EMT has been demonstrated to be more effective than just one alone. The Breather is also highly customizable. With 6 ...
How does the Breather differ from a PEP (Positive Expiratory Pressure) or OPEP (Oscilating PEP) device?
PEP or OPEP devices provide improved mucus clearance and airway defense. However, they have little or no long-term effect on respiratory muscle strength. The respiratory muscle strength provided by the Breather improves immediate and long-term cough ...
Breather vs Flutter
The Breather is the first drug-free evidenced based Inspiratory/Expiratory Respiratory Muscle Training (RMT) device used by COPD, CHF, Dysphagia, and Neuromuscular disease patients, as well as athletes, singers, and musicians. It trains both ...
