A lordotic curve of the cervical spine in the aged is a physiological curvature of the cervical spine. The swallowing disorder precipitated by lordosis of the cervical spine in the aged, the swallowing function and intervention were reported on. An 86-year-old woman complained of swallowing difficulty for a few months. A lordotic curve (physiological curvature) of the cervical spine was observed. In the neutral neck position, the cervical lordotic angle was 29° using the Cobb C2-C7 method. When the lordotic curve of the cervical spine was intentionally straightened, the lordotic angle became 0°, the laryngeal elevation changed from 0.5 times the height of a cervical vertebra to 1.75 times, the laryngeal elevation delay time changed from 0.5 seconds to 0.23, the percent laryngeal elevation changed from 50% to 72% and pharyngeal transit time changed from 0.83 seconds to 0.75. Lordosis of the cervical spine inhibited laryngeal elevation and influenced the swallowing function. In cases in which lordotic curvature of the cervical spine adversely influences the swallowing function in the aged, rehabilitation to manage the lordosis of the cervical spine is useful. For the purpose of effective intervention, not only diagnostic but also therapeutic videofluorographic examination of swallowing is very important.
老年人颈椎的前凸曲线是颈椎的生理曲度。本文报告了颈椎前凸导致的老年人吞咽障碍、吞咽功能和干预措施。一位 86 岁的女性抱怨吞咽困难已有数月。观察到颈椎存在前凸曲线（生理曲度）。采用 Cobb C2-C7 方法，在中立位颈部时，颈椎前凸角为 29°。当颈椎前凸曲线被有意拉直时，前凸角变为 0°，喉抬高从颈椎高度的 0.5 倍变为 1.75 倍，喉抬高延迟时间从 0.5 秒变为 0.23 秒，喉抬高百分比从 50%变为 72%，咽通过时间从 0.83 秒变为 0.75 秒。颈椎前凸抑制了喉抬高，影响了吞咽功能。在颈椎前凸曲线对老年人吞咽功能产生不利影响的情况下，康复管理颈椎前凸是有用的。为了进行有效的干预，吞咽的诊断性和治疗性视频荧光检查都非常重要。
