Clinical trials have shown that COPD patients who complete EMST training show improvements in breathing, both at rest and moderate physical activity, as well as improved swallowing function

The EMST150 is the most clinically validated expiratory muscle trainer and has been proven to be effective in strengthening weakened respiratory muscles that in turn cause shortness of breath (Dyspnea) and trouble swallowing (Dysphagia) for many COPD patients.

Although COPD is a progressive disease that gets worse over time, COPD is treatable. With proper management, most people with COPD can achieve good symptom control and quality of life and reduce the risk of other associated conditions. One effective way of delaying life-impacting symptoms, including shortness of breath, is to utilize the EMST150. EMST training can significantly improve expiratory muscle strength. Clinical trials have shown that COPD patients who complete EMST training show improvements in breathing, both at rest and moderate physical activity, and improve swallowing function. Alone or in combination, these improvements provide a general improvement in the quality of life.

Inspiratory Muscle Strength Training (IMST) with the IA150 adapter for People with COPD

People with COPD can also benefit from training their inspiratory muscles in addition to their expiratory muscle training with the EMST150. Inspiratory muscle strength training has been proven to strengthen the respiratory muscles, thereby improving the breathing ability and the overall strength of the respiratory system. Additionally, inspiratory muscle strength training has been proven to be efficient in enhancing physical performance and increasing physical endurance.

Inspiratory training with the EMST150 is achieved by simply attaching the available IA150 adapter to the device, making the one device capable of providing both expiratory and inspiratory muscle strength training.

Key Benefits for COPD Patients with EMST150 and IA150 Adapter 

  • Can Improve Breathing Capability by Strengthening Respiratory Muscles
  • Can Improve Swallowing Function and Reduce Related Choking Risks
  • Enhanced Quality of Life for COPD Patients
  • Improved Breathing & Swallowing Capability in as Little as Three to Four Weeks of Using the EMST150
  • Easy to Use, Drug-Free, No Risk Solution for COPD Patients


When patients with Chronic obstructive pulmonary disease (COPD) trained with the EMST150, the strength of the expiratory muscle was increased. Improvements in exhalatory breath pressure for persons with COPD can lead to decreased feelings of breathlessness and beneficial effects on exercise performance and quality of life.

“The main finding of the present study is the significant improvement in dyspnea at rest, health-related quality of life, and timed walking distance in COPD patients following a short expiratory muscle training period. Most of these changes were proportional to the improvement in expiratory muscle strength. It should be noted that improvements in SGRQ scores and walking test distance were not only statistically significant but also should be considered clinically relevant.”
