Clinical Trial Summary

The purpose of this study is to investigate the impact of expiratory muscle strength training (EMST) on the swallowing, breathing, oral intake, quality of life and cough function of people with oculopharyngeal muscular dystrophy (OPMD).


Clinical Trial Description

Outline: 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. ;
