summary Chin‐tuck position and reclining posture have been used in dysphagia patients to prevent aspiration during swallowing. However, both behavioural treatments may affect respiratory function. This study was carried out to test the hypothesis that if chin‐tuck posture and body reclining affected respiratory function, this would be associated with altered coordination between respiration and swallowing. To investigate this hypothesis, respiratory parameters and manometry were used in each of four combinations of reclining posture and chin‐tuck position. In the 60 °reclining with 60 °chin‐tuck position, duration of swallowing apnea (0·89 s.d. 0·17 s) and submental electromyography burst (2·34 s.d. 0·84 s) were significantly longer when compared to both upright sitting and 30 °reclining positions. We conclude that 60 °reclining from vertical with 60 °chin‐tuck may affect oral processing stages which delay and reduce a variety of oropharyngeal movements. These in turn significantly influence the coordination between respiration and swallowing.
