Currently, there are no efficacious behavioral treatment approaches to address uncompensated aspiration, or aspiration without appropriate cough response, in Parkinson's disease (PD). This is of particular public health concern given that aspiration pneumonia is the leading cause of death in persons with PD. The overarching aim of the proposed study is to determine the efficacy of two distinct intensive rehabilitation paradigms, expiratory muscle strength training (EMST) and sensorimotor treatment for airway protection (smTAP), on airway protective clinical outcomes in persons with PD and dysphagia. The investigators anticipate the results will lead to reductions in the risks associated with airway protective deficits.
