Lung Volume Recruitment Combined With Expiratory Muscle Strength Training in ALS

EMST uses a training device that has a valve set to 50% of a patient's maximum expiratory pressure (MEP). The patient exhales forcefully until the valve releases. Patients perform 5 sets of 5 repetitions a day, 5 days a week.

The bag is used to expand the lungs, after which the patient makes a voluntary cough. Half of the participants will perform the LVR technique in addition to the ESMT technique."
