Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Twenty participants with OPMD, with dysphagia, will be recruited from Neuromuscular clinics within Calgary. The investigators will enrol patients in a parallel group, sham-controlled, randomized clinical trial, with 10 participants in each group (active EMST and sham EMST).
Participants will have baseline measurements of: (i) global swallowing function via modified barium swallow study, (ii) maximum expiratory pressure, (iii) voluntary cough spirometry, (iv) forced vital capacity, (v) functional oral intake, (vi) patient report of self-perceived swallowing impairment (EAT-10 Questionnaire), and (vii) biomarker analyses.
Participants will undergo 5-weeks of EMST (active or sham). All baseline measurements will be repeated after 5-weeks of EMST and 10-weeks post-EMST to measure durability of effect.
Outcomes:
The end-goal of the current research is to obtain preliminary data for the benefit of EMST in a new study population, and direct future studies that may provide evidence for a new standard of care in treating neuromuscular diagnoses.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
EMST therapy
Participants use the EMST device as per study protocol, set to 50% of the patient's maximal expiratory pressure, as measured by handheld manometer.
Expiratory muscle strength therapy (EMST150, Aspire LLC)
Active therapy calibrated to the participant's maximum expiratory pressure
Sham EMST therapy
Participants use a sham EMST device that has the spring removed as per study protocol, with no significant airflow resistance.
Expiratory muscle strength therapy (EMST150, Aspire LLC)
Active therapy calibrated to the participant's maximum expiratory pressure

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* 18 years of age or older
* Must be capable of providing informed consent
* Must be able to undergo respiratory function testing and swallowing studies
* Must have a forced vital capacity (FVC) greater than 60%
* A score of 3 or greater on the Eating Assessment Tool-10 (EAT-10; self-administered, symptom-specific outcome instrument for dysphagia. A score of 3 or greater indicates increased stress around eating)
* A score of 26 or greater on the Montreal Cognitive Assessment (MoCA; 30-point screening assessment used for detecting cognitive impairment. A score of 26 or greater is considered to be within functional limits.)
Exclusion Criteria
* Acute myocardial infarction
* Moderate to severe hypovolemia
* Acute neurological events
* Unstable cardiac status
* Recent hernia
* Severe chronic obstructive pulmonary disease (COPD)
* Uncontrolled reflux issues
* Women who are pregnant, or who suspect they may be pregnant
* Cognitive impairment that would prevent comprehension of instructions and adherence to intervention guidelines (a score of less than 26 points on the MoCA)
