Summary

The purpose of this study is to investigate the effects of two treatment techniques called Expiratory Muscle Strength Training (EMST) and Lung Volume Recruitment (LVR) on breathing, swallowing, speech, and cough function in persons with mild to moderate ALS. Half of the participants will do EMST alone, and the other half of the participants will do EMST and LVR.

Conditions

Interventions

PROCEDURE

Expiratory Muscle Strength Training (EMST)

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.

PROCEDURE

EMST + Lung Volume Recruitment (LVR)

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. LVR is a technique to increase cough function that is performed with a resuscitation bag fitted with a mouthpiece and a one-way valve. 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.
