The EMST150 training system was originally tested on high school band students, both boys, and girls, nearly 20 years ago. The objective was to see if young people playing musical instruments that required strong expiratory power could increase their exhaled air pressure by power training with the EMST150. All the students that received training with the EMST150 experienced increased exhaled strength.

From this simple beginning, the EMST150 research team went on to apply the training to a diverse range of people and found the EMST150 trainer increased exhaled air pressure, or strength, in all who participated in the training. The EMST150 team recognized that various basic breathing-related functions such as coughing, swallowing, and speech were also improved by increasing expiratory power. Some of the most rewarding results came from working with individuals suffering from chronic neurological conditions and those seeking to stay healthy as they age.
Today, the EMST150 and the IA150 adapter for inspiratory strengthening are used to strengthen the most important muscles in the human body – those involved in breathing and airway protection.

Our experience, working hand in hand with doctors and clinicians around the globe, verifies EMST150’s nearly immediate and straightforward results and its ability to maintain its positive benefits with continued use. Simply put, the EMST150 is the only device of its kind that has been rigorously tested, is accurately calibrated, with countless reports of verifiable patient outcomes.

The Four D’s – Conditions Explained

Dysphagia (difficulty swallowing)
Dystussia (disordered cough)
Dysphonia (weakened speaking voice)
Dyspnea (shortness of breath)

These are clinically known by those involved in respiratory health as the ‘Four Ds.’ One or more of these health conditions are typically present in most people that are utilizing an Aspire Respiratory product. The most common of the Aspire devices used is the EMST150 which provides effective respiratory muscle strength training backed up by evidence-based clinical validation by specific patient need(s). The EMST150 has been clinically determined to effectively in addressing these needs as follows…

For Difficulty Swallowing (Dysphagia): EMST150 training improves swallowing function by improving hyoid and laryngeal excursions and improved laryngeal vestibule closure.

For A Disordered Cough (Dystussia): EMST150 training improves respiratory function by increasing maximum expiratory pressure and improving cough airflow measures.

For A Weakened Speaking Voice (Dysphonia): EMST150 training improves voice quality by improving subglottal pressure.

For Shortness of Breath (Dyspnea): EMST150 training decreases breathlessness, the paralyzing feeling of running out of breath, improving the ability to do exercise-based tasks with longer endurance.
