Inclusion Criteria:
- Diagnosis of adult onset of PD
- A history of freezing of gait (FOG) as evidence by clinical assessment
- A stable regimen of anti-parkinsonian medications
- Ability to walk at least 10m without assistance
- Ability to walk on a treadmill for 20 minutes
- Personal weight of less than 500 Lb (because the suspension harness over the treadmill is limited to 500 Lb
- Stage 3 of the Hoehn and Yahr disability scale
- A score of >24 on the Mini Mental State Examination
Exclusion Criteria:
- Evidence of any clinically significant functional impairment related to cardiovascular, pulmonary, metabolic, other neurologic or musculoskeletal disease criterial that would preclude participation in training
- Any medical condition that might require other medical or surgical treatment during the study period
- A history of brain surgery or placement of a deep brain stimulator
- Dyskinesias > grade 2 on the Unified Parkinson's Disease Rating Scale (UPDRS)

Experimental: Single Group
10 subjects with Parkinson's Disease receiving tPCS during the first session, treadmill walk, 7-10 days later (second session, and combined tPCS and treadmill 7-10 days week later (third session)
|
We will follow the procedure described by several investigators as safe and effective.
The participant will sit on a standard chair.
Two commercially available surface electrodes will be embedded in an elastic head cup.
Each electrode will be covered with a water soaked absorbent fabric.
One positive (+) electrode will be placed over the primary motor cortex (M1) and pre-motor areas.
One negative (-) electrode will be placed over the skin overlying the contra lateral supra-orbital region.
The electrodes will be connected via 2 leads to a battery powered direct current stimulator.
The stimulator will be programmed to deliver 0.975mA (peak 4mA) over 20 minutes.
The participant will walk on a treadmill for 20 minutes at the individually self-selected velocity determined at baseline.
Participants will have a combined session with CES while walking on the treadmill for 20 minutes at the individually self-selected velocity determined at baseline.

Number of Steps to Regain Balance
Periodo de tiempo: Data collection occurred before and immediately after each training session
|
Steps to regain balance were measured by the number of steps needed to recover standing balance.
The steps were counted using a custom software of the motion capture system.
|
Data collection occurred before and immediately after each training session

First Step Length
Periodo de tiempo: Data collection occurred before and immediately after each training session
|
First step length was measured in meters from the starting position of the foot to the maximum displacement of the foot after the first step.
Measurements were taken separately for forward and backward first step.
