The EMST 150 is an innovative handheld device that has been scientifically tested for its ability to improve muscle strength. A one of a kind device, the EMST 150 was designed by a team of researchers who understood the impact that muscle weakness can have on a person's overall health. The EMST 150 team recognized that increasing exhaled strength could improve basic breathing related functions such as cough, swallow and speech. The most exciting results to date have been through working with the elderly and individuals suffering from neurological disorders. In clinical trial after trial, the EMST 150 produced significant improvements in both healthy individuals and person's with Parkinsons, multiple sclerosis, spinal cord injury, and other types of neuromuscular disease. Weve also found that therapists could use the device with these types of patients to strengthen weakened muscles improving breathing, cough, swallowing and speech. And because the EMST 150 is the only device of this kind that is calibrated, therapists are able to measure and document progress during therapy programs.
