The present study had two purposes. The first was to provide variability data on objectively measured durational parameters of swallowing as accomplished by dysphagic patients secondary to stroke. The second was to examine the short-term effects of thermal application on these same durational measures. The study employed a cross-over design with each dysphagic stroke subject swallowing 10 times in both untreated and treated conditions. Two findings emerged: (1) swallowing durations in the 22 dysphagic stroke subjects were highly variable within and across subjects and have distributions that were nonnormal with nonhomogeneous variances; (2) thermal application reduced duration of stage transition (DST) and total swallow duration (TSD). Implications of these findings are discussed.
本研究有两个目的。第一个目的是提供因中风导致吞咽困难的患者客观测量的吞咽持续时间参数的变异性数据。第二个目的是研究热刺激对这些相同持续时间测量指标的短期影响。该研究采用交叉设计，每位吞咽困难的中风患者在未治疗和治疗条件下均吞咽10次。得出了两个结果：（1）22名吞咽困难的中风患者的吞咽持续时间在个体内部和个体之间差异很大，其分布呈非正态且方差不齐；（2）热刺激缩短了阶段转换持续时间（DST）和总吞咽持续时间（TSD）。讨论了这些结果的意义。
