About this trial

This is an interventional treatment trial for Parkinson Disease

Eligibility Criteria

50 Years - 90 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • patients with clinically established PD (Postuma et al. 2016)

Exclusion Criteria:

  • psychiatric disorders, including major depression, hallucinations
  • any MRI-incompatible metal in the body
  • epilepsy
  • lack of cooperation
  • presence of dementia

Sites / Locations

  • Central European Institute of Technology

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Sham Comparator

Arm Label

PD patients with real rTMS

PD patients with sham rTMS

Arm Description

Patients will receive real rTMS in a two weeks long sessions (10 sessions).

Patients will receive sham rTMS in a two weeks long sessions (10 sessions).

Outcomes

Primary Outcome Measures

Changes in score of the 3F Test (the unabbreviated title- "the 3F Test Dysarthric Profile")
The 3F Test Dysarthric Profile enables clinicians to characterize a wide range of signs and symptoms of dysarthria. The minimum value of this scale is 0 (anarthria), the maximum value is 90 (no disorder). Higher scores of this scale mean better outcome. This test will be administrated by speech pathologist.

Secondary Outcome Measures

Resting state
The effect of stimulation on the resting state networks will be studied using fMRI measurement.

5. Study Description

Brief Summary
Hypokinetic dysarthria (HD) is common in Parkinson's disease (PD) patients and responds only partially to pharmacotherapy and surgery. The investigators will explore long-term effects of repetitive transcranial magnetic stimulation (rTMS) applied over right superior temporal gyrus, brain area known to be engaged in the feedback control of voiced speech. The project results will allow for the identification of potential therapeutic effects of rTMS as a tool that could contribute to the speech therapy of HD in PD patients. The results will also enhance our understanding of brain mechanisms underlying specific long-term effects of rTMS.
Detailed Description
A two parallel group, randomized, placebo controlled design will be used. Twenty PD patients will be stimulated in a two weeks long therapeutical sessions (10 sessions). Other twenty PD patients will be stimulated with the same protocol using sham stimulation. An MRI protocol consisting of T1, EPI BOLD, and DTI (diffusion tensor imaging) sequences and speech evaluation (acoustic signal processing and 3F test) will be performed prior to and after 10 days of rTMS and then repeated after 4, 8 and 12 weeks.
