title: Workshop--cough: exercise, speech and music.
abstract: Twelve distinguished scientists attended the workshop, heard three presentations, and took part in the discussions. Fontana first described his unpublished studies on cough in exercise and during hyperventilation with healthy subjects. Both activities depressed cough induced by inhalation of distilled water aerosol (fog). The possible mechanisms were discussed. Gibson then described the successful use of speech therapy to treat chronic cough, and discussed the possible mechanisms, centering on the role of the larynx and its neural control. A comparison was made with the ability of speech and laughter to precipitate cough. Widdicombe discussed the scanty literature on the effect of singing and playing wind instruments on cough, most of the evidence being anecdotal. In the discussion periods several matters for future study arose. It is usually not clear if the modulation of cough, its depression, enhancement or excitation, arose primarily at peripheral sites (reflexes from the airways), or at a cortical level, or both. Nor is it clear whether the same results would be obtained with provoked cough and with spontaneous cough. But all three aspects of 'behavioual' changes in cough sensitivity (exercise, speech and music) could be further explored, and current techniques should make this possible.
