Abstract
Oral diadochokinesis (oral-DDK) is one of the common maximum performance task used in clinical practice to evaluate the oral motor mechanism. Although there are reference values for some languages, there are no recent publications of adult population speaking Spanish, German or Czech.
Aims: 1) to describe the values of oral-DDK in adult speakers of Spanish, German and Czech, 2) to determine the influence of gender on the values of oral-DDK, 3) to determine the influence of age on the values of oral-DDK and, 4) to compare the inter-language values of the oral-DDK.
Methods & Procedures: the recordings of 189 healthy adults were considered (between 26 to 86 years), 94 females and 95 males, while producing the sequential motion rate (SMR) /pa-ta-ka/. Count-by-time method was used using an acoustic analysis software. Oral-DDK averages were established for each language and the effect of gender and age was determined. The variability of the measure among languages was also established.
Results: reference data were obtained for each language. Age did not show any significant effect on oral-DDK despite its decline as age advanced; there was no gender effect on the oral-DDK, and the comparison of the oral-DDK among languages showed statistically significant differences.
Conclusions: This study determined the reference data of the oral-DDK for Spanish, German and Czech and found significant differences among the three languages and no significant effects of age or gender on the measure studied.
