Patients with neurodegenerative diseases (ND) frequently experience concomitant impairments in pulmonary, cough, and swallow function. These impairments can lead to accelerated morbidity and mortality due to adverse events (e.g. aspiration pneumonia, respiratory failure, malnutrition/dehydration). Historically, exercise-based interventions have been avoided in patients with ND due to fear that they may lead to faster disease progression and increased fatigue, yet, emerging evidence has revealed moderate exercise training in patients with ND may prolong function, life, and quality of life. This has led to the proposal of a paradigm shift from reactive to proactive management of these patients. Therefore, there is high demand for noninvasive, portable methods for continuously monitoring pulmonary and swallow function in patients with ND to proactively implement palliative interventions and mitigate adverse events. Yet, few exist. Gold standard assessments (e.g. spirometry, videofluoroscopy) require in-person clinic visits, which can be challenging for patients with ND to attend due to physical mobility impairments, transportation issues, multifactorial health problems, and compromised immune systems (e.g. COVID-19 pandemic). Therefore, this dissertation examined: 1) The safety, tolerability, and impact of exercise-based interventions on function and quality of life in patients with amyotrophic lateral sclerosis (PALS); and 2) The ability of a novel, non-invasive, sensor-based technology (high-resolution cervical auscultation [HRCA]) to characterize swallow function in patients with ND. To examine Aim 1, the first experiment examined the impact of respiratory interventions on pulmonary, cough, and surrogates of swallow function in PALS and the second experiment investigated the impact of exercise-based interventions on function and quality of life in PALS via a systematic review. To investigate Aim 2, the third experiment explored HRCA’s ability to differentiate betwee
