Abstract

Diadochokinetic (DDK) speech task has been utilized as an evaluating tool for speakers with dysarthria for many years. This study attempted to differently diagnose multiple system atrophy (MSA) from idiopathic Parkinson's disease (PD) using patients' performance of DDK (i.e., alternate motion rate (AMR)). The subjects included 11 cases of pathologically confirmed MSA and 16 IPD patients who commonly presented with parkinsonian syndrome. The speech sample of each patient was analyzed acoustically using the MSPTM(Motor Speech Profile, a module of CSL). The results showed that the average DDK rate was significantly faster in the IPD than the MSA groups in all three syllables (i.e., /puh/, /tuh/. and /kuh/). We propose the average DDK rate variable as a core clinical trait in differentiating the two pathological conditions.
