Conditions

Parkinson&#39

Interventions

In cross-sectional study, we assess the speech of participants. The correlation between characteristics of speech in Parkinson&#39

s disease patients and other patients is analyzed. Parkinson&#39

s disease patients treated only with medical therapy. Cerebellar disease patients. Patients of upper motor neuron disease. Patients of lower motor neuron disease.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: 1. Parkinson's disease patients who undergo deep brain stimulation in Nagoya university hospital. 2. Patients of cerebellar and upper/lower motor neuron disease in Nagoya university hospital.

Exclusion criteria

Exclusion criteria: Patients with further neurological disease, severe cognitive impairment or psychiatric disorders that may hinder the assessment.

Design outcomes

Primary

Measure	Time frame
Characteristics of speech rhythm disturbance in Parkinson's disease patients differs from the cerebellar, upper/lower motor neuron disorders patients. Acoustically, we'll use the syllable repetition /pa/. To assess the speech intelligibility and speech characteristics we use perceptual assessment.	—
