About this trial
This is an interventional treatment trial for Parkinson's Disease
Eligibility Criteria
Inclusion Criteria:
Inclusion criteria: patients diagnosed with PD, with Hoehn and Yahr Stage between 1-3.5, who suffer from FOG, as measured at screening by the previously validated new FOG questionnaire (NFOG-Q), whose medications have not changed within 1 month of the study and are not anticipated to change during the study, are able to walk independently, and who are between the ages of 40-80 inclusive.
Exclusion Criteria:
Subjects who show no FOG during testing in the lab in response to a FOG provoking protocol, any diagnosed psychiatric or other neurological disorder, stroke, unbalanced and high blood pressure, pregnancy, participation in any clinical trial in the last three months, unwillingness to be randomized; implanted with deep brain stimulation, pacemakers, intracranial electrodes, implanted defibrillators or any other prosthesis; or a perceived inability to complete the study. Additional exclusion criteria related to tDCS safety will include a personal or family history of epilepsy, the use of neuro-active drugs, or risk of metal fragments in the eyes or head.

Sham Comparator
Active tDCS
Sham tDCS
The active tDCS condition will consist of 20 min of continuous stimulation. This amount of stimulation is safe for healthy young and older adults and has been shown to induce acute beneficial changes in cortical excitability and cognitive functions.
The Sham tDCS - an inactive stimulation.
