Brief Summary
Up to 90% of patients with Parkinson's disease (PD) have hypokinetic dysarthria (HD) in the early phase of the illness. HD is characterized by a harsh breathy voice quality, reduced variability of pitch and loudness and imprecise articulation. This project investigates the novel combination of speech therapy and home-based non-invasive brain stimulation (tDCS) treatment in order to increase overall positive effects on HD in PD. Using a novel multimodal analysis approach based on functional magnetic resonance and acoustic signal processing, we will be able to monitor changes in different domains of speech, as well as associated changes in brain plasticity.

Outcome Measures
Primary Outcomes (1)
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.
At baseline assessment (Visit- V0), after completion of 4 weeks of intervention (stimulation+ speech therapy) (Visit V1) and 4 weeks after completion of intervention (Visit V2)
Secondary Outcomes (1)
Resting state fMRI
At baseline assessment (Visit- V0), after completion of 4 weeks of intervention (stimulation+ speech therapy) (V1) and 4 weeks after completion of intervention (V2)
Study Arms (2)
PD patients with real tDCS and speech therapy
ACTIVE COMPARATORPatients will receive real tDCS during 4 weeks, 5 sessions per week. Altogether 20 sessions, each 20 minutes long. Stimulation is combined with Lee-Silverman voice treatment, 4 sessions per week. Altogether 16 sessions, each 1 hour long.
PD patients with sham tDCS and speech therapy
SHAM COMPARATORPatients will receive sham tDCS during 4 weeks, 5 sessions per week. Altogether 20 sessions, each 20 minutes long. Stimulation is combined with Lee-Silverman voice treatment, 4 sessions per week. Altogether 16 sessions, each 1 hour long.
Interventions
Home-based transcranial direct current stimulation- anode over right STG, cathode over left STG, 2 mA stimulation with 1x1 tDCS mini-CT device by Soterix Medical
Home-based transcranial direct current stimulation- anode over right STG, cathode over left STG, sham stimulation with tDCS mini-CT device by Soterix Medical
Remote Lee Silverman Voice Treatment (LSVT) delivered via telepractice by speech therapist. LSVT is a high-effort speech therapy that is primarily focused on improving speech loudness during 16 individual one-hour sessions in one month.
