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 degrees reclining with 60 degrees 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 degrees reclining positions. We conclude that 60 degrees reclining from vertical with 60 degrees 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.
低头姿势和斜躺姿势已被用于吞咽困难患者，以防止吞咽时发生误吸。然而，这两种行为治疗方法都可能影响呼吸功能。本研究旨在检验以下假设：如果低头姿势和身体斜躺会影响呼吸功能，那么这将与呼吸和吞咽之间协调性的改变有关。为了探究这一假设，我们在斜躺姿势和低头姿势的四种组合中，分别使用呼吸参数和测压法进行研究。在60度斜躺并伴有60度低头姿势时，与直立坐姿和30度斜躺姿势相比，吞咽呼吸暂停的持续时间（平均标准差0.89秒，标准差0.17秒）和颏下肌电图爆发（平均标准差2.34秒，标准差0.84秒）明显更长。我们得出结论，从垂直方向60度斜躺并伴有60度低头姿势可能会影响口腔处理阶段，从而延迟并减少各种口咽运动。这些反过来又会显著影响呼吸和吞咽之间的协调性。
