Effects of an Intensive Exercise-Based Swallowing Program for Persons With Parkinson's Disease and Complex Medical History: A Single-Case Experiment.

Purpose Dysphagia treatments to address the deterioration of oropharyngeal and respiratory functions in Parkinson's disease (PD) are few and rarely researched in persons with complex medical histories. This research note explored the effects of an intensive exercise-based swallowing program (ISP) that incorporated lingual and respiratory exercises for persons with PD and complex medical history. Method A single-case experiment was conducted across a 4-week ISP of lingual training and expiratory muscle strengthening for 2 participants (67-year-old man and 61-year-old woman).
