Objective: Determine the reported prevalence and characteristics of limitations on oral motor activities, mastication, swallowing, and other oral motor activities in patients with McArdle disease. Methods: An observational study was carried out in 28 patients using a standardised questionnaire on mastication and oral motor function. Results: 57\% of the participants reported difficulties with mastication. Muscle cramps during mastication occurred in 57\% of the patients. A feeling that food remains in the throat occurred in 32\%. Adaptations during mastication were needed in 42\% of the patients. Mastication difficulties, muscle cramps during mastication and mastication adjustments were inversely correlated with age (r2 = -0.445, p {\ensuremath{<}} 0.05; r2 = -0.509, p {\ensuremath{<}} 0.01; r2 = -0.456, p {\ensuremath{<}} 0.05). Feeling of food remaining in throat, cramps during mastication and during other oral motor muscle activities, were correlated with disease severity (r2 = 0.476, p {\ensuremath{<}} 0.01; r2 = 0.463, p {\ensuremath{<}} 0.01; r2 = 0.461, p {\ensuremath{<}} 0.01; r2 = 0.432, p {\ensuremath{<}} 0.05). Conclusions: In short, reported mastication difficulties are prevalent in people with McArdle disease, most frequently in younger people. Therefore, awareness of mastication and oral motor problems is required}, keywords = {McArdle disease, glycogen storage disease type V, mastication, oral motor function}, issn = {2214-3599}, url = {https://doi.org/10.3233/JND-180320} }
