A Pilot Study of Lung Volume Recruitment Combined With Expiratory Muscle Strength Training in ALS

Study Purpose:

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.
