目的下巴向下的姿势是医疗保健专业人员常用的姿势，用于缓解吞咽困难的症状。然而，该技术如何影响吞咽生理学尚不清楚。我们的目标是检查姿势技术对患有各种健康状况和吞咽障碍的患者的影响。方法通过电视透视检查对 15 名患者进行下巴朝下和中立头位的颞部和功能测量。此外，还检查了头部位置之间的时间差异，以确定下巴向下姿势期间是否存在改善。结果主要发现是，与中立头部位置相比，下巴向下姿势吞咽延长了过早溢出的药团进入咽部到吞咽开始之间的经过时间（p = .006）。此外，在执行姿势技术时，没有发现气道保护得到改善。结论：下巴向下的姿势可能有益于患有特定吞咽障碍的患者。然而，对所有吞咽困难的患者普遍使用该技术可能会被忽视，并且可能对患者的治疗结果产生不利影响或没有影响。未来需要对具有相同病理生理学的患者进行研究，以了解基于吞咽障碍的下巴姿势的益处。
PurposeThe chin-down position is a commonly prescribed posture by health care professionals to alleviate the symptoms of dysphagia. Yet, how the technique influences swallowing physiology lacks clarity. Our goal was to examine the impact of the postural technique on patients with various medical conditions and swallowing impairments.MethodTemporal and functional measures were examined with videofluoroscopy in the chin-down and neutral head position on 15 patients. Also, timing differences between head positions were examined to determine the presence of improvement during the chin-down posture.ResultsThe primary finding was chin-down posture swallows prolonged the elapsed time between when the prematurely spilled bolus entered the pharynx relative to swallow onset compared to the neutral head position (p= .006). Also, no improvement in airway protection was found when performing the postural technique.ConclusionsThe chin-down posture may benefit patients with specific swallowing impairments. However, the general use of the technique for all patients who experience swallowing difficulty might be negligent and could potentially have adverse or no effect on patient outcomes. Future studies examining patients with the same pathophysiology are needed to understand the benefit of the chin-down posture based on swallowing impairment.
