Zusammenfassung
Background: The temporal coordination of respiration and swallowing is provided by an extended pontomedullary neuronal network. However, it is not well known which factors influence swallowing parameters and the breathing pattern during normal swallowing. Methods: The study included 60 healthy subjects, median age 49y. A 2-channel computer assisted system was used to obtain concurrent respiratory and submental surface electromyography signals. Subjects were seated in an upright position and asked to swallow a bolus of 5,10, 25ml water and 5ml applesauce presented in random order. Eight swallows of each bolus vol…
