Speech evaluation protocols include oral diadochokinesia tests that consist of rapid repetition of a syllable or syllable sequences as quickly as possible [14].
We also hypothesized that oral diadochokinesia would show higher correlations with part A of TMT (motor measure) than with part B of TMT (cognitive-motor measure) or delta of TMT (cognitive measure).
Then, participants were assessed with TMT, phonemic/semantic verbal fluency test, and oral diadochokinesia test.
In the oral diadochokinesia test, participants were asked to say the /pataka/ sequence as fast as they could.
Analyses of variance (ANOVA) were performed to compare executive function, verbal fluency, and oral diadochokinesia (considered as dependent variables) of both groups.
Pearson correlation tests examined possible correlations between executive function, verbal fluency, and oral diadochokinesia in PD group.
Pearson correlation tests investigated possible relationships between the times on part A, part B, and delta of TMT, the number of words said on phonemic/semantic verbal fluency tests, and the number of syllables repetitions in oral diadochokinesia test.
The correlations between parts A and B of TMT and oral diadochokinesia were significantly stronger than the correlation between delta of TMT and oral diadochokinesia (p = 0.011 and p = 0.018, resp.) (Table 3).
The present study compared the performance of people with PD with a control group on executive function, phonemic/semantic verbal fluency, and oral diadochokinesia tests.
People with PD said less syllables/second than controls in oral diadochokinesia. In dual tasks with motor and cognitive demands, patients with PD have difficulty in both components (e.g., gait [20] and alternating steps [21]).

Disturbances to the cerebellum result in decrease muscle tone on the ipsilateral side, poor coordination of fine motor movements and problems with gait.[23] Other problems include ataxia, intention tremor,
diadochokinesia, dysmetria, hypotonia and asthenia.[11] Another important problem which may occur, especially in a hemorrhagic stroke or other situations leading to increased intracranial pressure, is the downward movement of the cerebellar tonsils through the foremen magnum resulting in a tonsillar herniation and compression of the medulla.[18]
