Abstract: Purpose: to explore whether the diadochokinetic index of syllable production variability (DDKcvp%) is useful for the detection of articulatory inaccuracies in different stages of Parkinson's disease (PD). Methods: a diadochokinetic speech task of the consonant-vowel type [pa-pa-pa] was applied to 18 people with PD (classified in stages of progression from 1 to 5 according to the Hoehn & Yahr scale) to determine their diadochokinetic performance. Records of the study group were compared to a reference valu… Show more
