对10例脑血管意外（中风）后3周轻度吞咽困难患者、10例正常受试者和8例神经功能受损的中度至重度吞咽困难患者的口咽吞咽进行了视频荧光成像研究，以检查2种丸剂温度的影响（室温和33华氏度），2体积，和2粘度对咽阶段吞咽事件的持续时间以及口咽吞咽问题和食团输送的频率和性质的影响。正常受试者表现出显着较长的咽部反应时间和较长的喉抬高只有1毫升冷液体。中风患者和8例明显吞咽困难的神经功能受损患者的吞咽障碍或吞咽措施表现出非常少的显着影响的温度。在两个神经功能受损的患者组中，推注量和粘度的增加减少了咽部延迟时间。与正常受试者相比，中风患者在某些推注量和粘度方面表现出明显更长的咽部延迟时间，但更短的咽部反应时间，喉关闭，颈咽开口和喉提升。结果进行了讨论，在潜在的治疗效果的丸量和粘度。
The oropharyngeal swallow of 10 patients with mild dysphagia at 3 weeks after a cerebrovascular accident (stroke), 10 normal subjects, and 8 neurologically impaired patients with moderate to severe dysphagia was studied videofluorographically to examine the effects of 2 bolus temperatures (room temperature and 33-degrees-F), 2 volumes, and 2 viscosities on the durations of pharyngeal stage swallow events and the frequency and nature of oropharyngeal swallowing problems and bolus transit. Normal subjects exhibited significantly longer pharyngeal response times and longer laryngeal elevation only for 1 ml cold liquid. The stroke patients and the 8 significantly dysphagic neurologically impaired patients exhibited very few significant effects of temperature on swallowing disorders or swallow measures. Increases in bolus volume and viscosity decreased pharyngeal delay times in both neurologically impaired patient groups. Stroke patients exhibited significantly longer pharyngeal delay times but shorter pharyngeal response times, laryngeal closure, cricopharyngeal opening, and laryngeal elevation than normal subjects on some bolus volumes and viscosities. Results are discussed in terms of the potentially therapeutic effects of bolus volume and viscosity.
