The EMST150  is the most scientifically tested, clinically proven, handheld expiratory muscle strength trainer available! Designed by a well-respected team of researchers, the one-of-a-kind EMST150 device now has nearly two decades worth of evidence-based outcomes. The EMST150 research team and scientists worldwide know that the simple use of the EMST150 over a short period of time results in an unquestionable improvement in breathing force while improving the strength of cough, swallow, and voice. In trial after trial, the EMST150 training system has shown significant improvements in the strength of healthy individuals and individuals diagnosed with neurological/neurogenic diseases such as Parkinson’s disease, stroke, head and neck cancer, multiple sclerosis, ALS, and spinal cord injury, as well as snoring and sleep apnea (OSA). The latest studies also show promising results in other types of disease, including Pompe and Huntington’s chorea.

How it Works

The EMST150’s exceptional design uses a unique, calibrated pressure relief valve that creates an isometric load to the muscles used for coughing, swallowing and breathing out. This is similar to the experience of lifting weights to strengthen muscles in other parts of your body. It uses the same principle as the weight machines in the gym. The EMST150™ is quite simply your hand-held “weight machine.”

The EMST150™ can be carried with you anywhere and used anytime to improve and maintain your muscle strength even after you complete your initial training! It is calibrated so you can measure your progress over time as you progress to higher levels of ability, again, just like lifting weights. The calibration on the EMST150 is adjustable from 30-150cm of H20 (water pressure), allowing for a safe and full range of use as the breathing, swallow, cough, and voice strength increases during your training program. This calibration feature allows you to measure your progress over time accurately. The EMST150 device is so lightweight and compact it can travel anywhere with you, in your gym bag, handbag or briefcase, or simply exercise in the comfort of home.
