简要总结
A tele-health treatment study for individuals with early stage ALS with the aim to improve communication, cough response, and respiratory strength. All participants complete a respiratory strength training program using an Expiratory Muscle Strength Training (EMST 150) device from the comfort of their homes for 6 weeks.
详细描述
The investigators are looking for people with early stage ALS to participate in a completely tele-health (no in-person visits required) treatment study examining the effects of an Expiratory Muscle Strength Training device (EMST-150) on communication, cough, and respiratory strength. Participants will be required to attend 2 virtual baseline assessment sessions followed by 12 additional virtual training sessions (2 per week for 6 weeks). Participants should plan to be actively enrolled in the study for ~10 weeks (3 weeks of baseline monitoring followed by 6 weeks of training). Participants will also be required to fill out a series of questionnaires assessing the EMST's effectiveness via tele-health.

研究组 & 干预措施
Expiratory Muscle Strength Training
All participants will forcefully breathe out into an Expiratory Muscle Strength Training device (EMST-150) 25 times per day for 6 weeks. The EMST device will be set at a moderate intensity level (50% of each participant's maximum expiratory pressure).
干预措施: Expiratory Muscle Strength Training (EMST-150) (Device)
