Concerns about the preparation of thickened beverages for patients with dysphagia highlight the need for objective measurements with application to clinical settings. This cross-sectional study examined the line spread test (distance a liquid flows) to determine reproducibility of the measurements and whether specific line spread measurements can differentiate nectar- and honey-like thickness levels in the National Dysphagia Diet. Two common thickeners were tested in three different beverages. Replication of preparation procedures allowed comparison of product/beverage line spread results to viscometer-determined viscosity measured at a similar temperature and time to thicken. Analysis of variance showed a significant two-way interaction for both levels of thickness, indicating that line spread measurements differentiated products mixed with different beverages. Standard deviations and confidence intervals confirmed that measurements were highly repeatable. Line spread distance (cm) and viscosity measured in centipoise (cP) for a similar product/beverage statistically correlated with one another, suggesting that line spread and viscometry provided some similar information about thickness across the six product/beverage combinations tested.
对于吞咽困难患者制备增稠饮料的担忧凸显了在临床环境中进行客观测量的必要性。这项横断面研究检查了线扩散试验（液体流动的距离），以确定测量的可重复性，以及特定的线扩散测量是否能够区分国家吞咽困难饮食中的花蜜状和蜂蜜状浓稠度水平。在三种不同的饮料中测试了两种常见的增稠剂。制备程序的重复使得能够将产品/饮料的线扩散结果与在相似温度和增稠时间下用粘度计测定的粘度进行比较。方差分析显示，两种浓稠度水平均存在显著的双向交互作用，表明线扩散测量能够区分与不同饮料混合的产品。标准差和置信区间证实测量具有高度可重复性。对于相似的产品/饮料，以厘米为单位测量的线扩散距离和以厘泊（cP）为单位测量的粘度在统计学上相互关联，这表明线扩散和粘度测定在测试的六种产品/饮料组合中提供了一些关于浓稠度的相似信息。
