Primary outcomePrimary: Change in Time-to-laryngeal-vestibule-closure Thin Liquids — 0 milliseconds
Summary
Context: Many people with Parkinson Disease (PwPD) experience swallowing difficulties, particularly with food/liquid going down the wrong way or remaining in the throat after swallowing. Prior studies suggest that exercise-based treatments targeting swallowing strength may be effective in reducing these difficulties.
Research question: Does an exercise-based treatment involving the effortful swallow maneuver improve swallowing function in PwPD?
Study plan: The investigators will study the effects of a four-week intensive swallowing rehabilitation program in PwPD, over a 2-year period.

Eligibility Criteria
Inclusion Criteria
- At least 18 years old
- English-speaking
- Able to follow study instructions
- Neurologist confirmed diagnosis of PD
- Hoehn and Yahr scale score of 2 or 3
- Self-report of one or more swallowing or related symptoms:
- Difficulty with secretion management
- Coughing at the meal time
- Choking on food
- Respiratory infection in the past 6 months (other than COVID)
Exclusion Criteria
- History of head and neck cancer
- Radical neck dissection (e.g. anterior cervical spine surgery) or neck/ oropharyngeal surgery (not excluded - tonsillectomy, adenoidectomy)
- Past medical history of any neurological disease other than PD (e.g. multiple sclerosis, amyotrophic lateral sclerosis, traumatic brain injury, stroke)
- Cognitive or receptive communication difficulties that preclude the participant's ability to follow study instructions provided in English. This will be determined by the participant's physician prior to referring them to the study.
