PurposeThis prospective investigation evaluates oral weakness and its impact on swallow function, weight, and quality of life in patients with oculopharyngeal muscular dystrophy (OPMD).

MethodIntraoral pressure, swallow pressure, and endurance were measured using an Iowa Oral Performance Instrument in participants with OPMD and matched controls. Timed water swallow, weight, and quality of life were also assessed.

ResultsParticipants with OPMD were weaker than controls. Oral weakness impacted strength, swallow pressure, swallow capacity, swallow volume, swallow time, and quality of life. Tongue endurance was not affected by oral weakness.

ConclusionThis investigation provides further insight into the swallow function of patients with myopathic disease. Muscle fiber loss leads to weakness, which results in reductions in swallow function and quality of life. Weight and endurance are not greatly altered.
