This paper briefly reviews information available on exercise stimulus intensity and its interaction with stimulus duration, as well as reviews the current information on different dysphagia treatment modalities as they relate to treatment intensity and duration. The available literature in this area suggests that exercise modalities are distinct and different with regard to the metabolic pathways accessed as a function of both stimulus intensity and duration. Defining treatment prescriptions for dysphagia is difficult at this time, however, because only limited data on stimulus duration or intensity is available for existing indirect and direct treatments. Acknowledgment of exercise physiology paradigms and mechanisms of muscle response to treatment is critical to design of rehabilitation protocols.
