Dysphagia post-stroke represents a substantial health issue. The rates of pneumonia are lesser among those individuals who have passed a dysphagia screening test. Only few among the existing screening tests meet the required standards; the timed water swallow test (TWST) is one among them. The purpose of the study was to establish normative data for the TWST in Indian population.
The present study involved 480 typical individuals in the age range of 8-80.11 years. All the participants performed TWST and indices of volume per swallow, time per swallow, and swallow capacity were obtained for the tasks of normal and rapid swallow across age and gender.
In the first phase of the study, normative data were obtained and summarized by age and gender. The second phase of the study dealt with additional analyses on measures of reliability and validity. Two-way mixed ANOVA was performed with age and gender as the between-group variables, and normal and rapid swallowing as the within-group variables.
Normative values for the performance of Indian population on TWST were obtained. The results revealed a significant difference for all the three indices of swallow performance across age, gender, and type of swallowing. These norms can be used as a screening tool for identifying swallowing dysfunction.
中风后吞咽困难是一个重大的健康问题。通过吞咽困难筛查测试的个体患肺炎的几率较低。现有的筛查测试中只有少数符合要求标准；定时饮水吞咽测试（TWST）就是其中之一。本研究的目的是建立印度人群TWST的标准数据。
本研究纳入了480名年龄在8至80.11岁之间的典型个体。所有参与者都进行了TWST，并获取了不同年龄和性别的正常吞咽和快速吞咽任务的每次吞咽量、每次吞咽时间和吞咽能力指标。
在研究的第一阶段，按年龄和性别获取并总结了标准数据。研究的第二阶段对可靠性和有效性指标进行了额外分析。以年龄和性别作为组间变量，正常吞咽和快速吞咽作为组内变量进行双向混合方差分析。
获得了印度人群TWST表现的标准值。结果显示，吞咽表现的所有三个指标在年龄、性别和吞咽类型方面均存在显著差异。这些标准可作为识别吞咽功能障碍的筛查工具。
