RecruitingDevice studyCombined Respiratory Training in Persons With ALSThe goal of this interventional trial is to learn about lung volume recruitment (LVR) and expiratory muscle strength training (EMST) in a total of up to 39 patients diagnosed with ALS. The following aims will be addressed: 1. Determine the impact of combined LVR and EMST on cough strength and respiratory function in individuals with ALS. 2. Determine the impact of combined LVR and EMST on patient-reported dyspnea and bulbar impairment. 3. Describe the effect of combined LVR and EMST on patient- and caregiver reported burden and quality of life.
