Swallowing in Parkinson Patients versus Healthy Controls: Reliability of Measurements in Videofluoroscopy
Table 4
(a) Descriptive statistics of temporal data (quantitative assessment) and level of significance () for the comparison of differences between Parkinson patients and the healthy control subjects (Mann-Whitney test asymp. sig., 2-tailed). (b) Descriptive statistics of spatial-temporal data (hyoid motion) and level of significance () for the comparison of differences between Parkinson patients and the healthy control subjects (Mann-Whitney test asymp. sig., 2-tailed). (c) Crosstabulation of visuoperceptual data and level of significance () for the comparison of differences between Parkinson patients and the healthy control subjects (Chi-Square test asymp. sig., 2-sided). The number of swallows per level of the three or five point scales is in parentheses.
