这项研究的主要目的是调查部分和完全头部旋转和下巴收起对正常健康成年人咽部和UES咽部和UES吞咽压力和持续时间的即时影响。10人(3男7女，年龄54-76岁)作为参与者。受试者在直立姿势下进行固态腔内测压，同时执行吞咽动作，头部处于正常位置，头部旋转(部分和完全)，下巴收起，下巴向下。使用颈椎活动度(CROM)测斜仪准确测量头部旋转和下巴内翻的程度。CROM倾斜仪以前从未使用过，因此这是我们所知的第一个量化头部旋转程度和下巴内翻程度的研究。来自这些健康受试者的测压数据表明，部分和完全头部旋转都可以增加UES放松的持续时间，降低UES残余压力。下巴内翻可能有效地延长上咽的持续时间。部分下巴收起(下巴向下)可减少残馀压力。完整的头部旋转和下巴收拢比部分动作提供了更多的整体好处。然而，对于头颈部活动受限的患者，部分体位改变以类似的方式影响咽部，并可能提供临床上有意义的好处。有必要对患者群体进行额外的研究。
The primary aim of this study was to investigate the immediate effects of partial versus complete head rotation and chin tuck on pharyngeal swallowing pressures and durations in the pharynx and UES of normal, healthy adults. Ten individuals (3 men and 7 women; age range 54-76 years) served as participants. Solid-state intraluminal manometry was performed with the participants in the upright position while performing swallows with the head in the normal position, head rotated (partial and complete), chin tucked, and chin down. A cervical range of motion (CROM) inclinometer was used to accurately measure the degree of head rotation and chin tuck. The CROM inclinometer has not been used before so this is the first study to our knowledge to quantify degree of head rotation and chin tuck. Manometric data derived from these healthy participants indicate both partial and complete head rotations can increase the duration of UES relaxation and decrease UES residual pressure. Chin tuck may be effective in increasing durations in the upper pharynx. Partial chin tuck (chin down) decreases UES residual pressure. Complete head rotation and chin tuck provide more overall benefit than partial maneuvers. However, for patients with limited head and neck mobility, partial posture changes impact the pharynx in similar ways and may provide clinically meaningful benefits. Additional research on patient populations is warranted.
