The aim of this study is to compare two physical therapy training consisting of gait training that are distinguished by one being associated with tasks that require handling of the main executive functions, performed by individuals with Parkinson's Disease.
The investigators hypothesis is that the experimental group (EG), which hold gait training with higher cognitive demands (dual-task condition), will make improvements in the parameters measured (functionality of gait and cognitive ability) to a greater extent compared to the control group (CG), which hold gait training without executive tasks (single-task condition).

The aim of this study is to compare two physical therapy training consisting of a gait training that are distinguished by one being associated with tasks that require handling of the main executive functions (protocol designed by the same team), performed by individuals with Parkinson's Disease.
Both training consists of 30 minutes of global exercises that involves stretching, muscle strengthen and axial mobility exercises, with the following difference:
- the experimental group (EG) will hold another 30 minutes of gait training in a dual-task condition associated with distracting tasks that require handling of the main executive functions;
- the control group (CG) will hold an additional 30 minutes of gait training without associated tasks.
It will be a prospective study, single blind, randomized, where 30 patients with PD in stages 1 to 3 on Hoehn & Yahr scale will participate in the study, to be held in Brazil Parkinson Association. Patients will be randomized into an experimental and control group, 15 in each one.
The training will consist of 10 sessions, two times per week for five weeks. The executive tasks concomitant with gait training cover the following executive functions: volition, self-awareness, planning, response inhibition, response monitoring and attention.
The main outcome measures are: (1) Dynamic Gait Index (DGI), (2) Montreal Cognitive Assessment (MoCA), (3) Trail Making Test A and B, (4) Unified Parkinson's Disease Rating Scale (UPDRS) and (5) Falls Efficacy Scale (FES).

Experimental: Gait training executive functions tasks
The experimental group will perform a gait training associated with the tasks that require the main executive functions (dual-task condition).
|
Behavioral: Gait training executive functions tasks
The training will consist of 10 sessions, two times per week for five weeks, and consists of 30 minutes of global exercises that involves stretching, muscle strengthen and axial mobility exercises, and another 30 minutes of gait training in a dual-task condition associated with distracting tasks that require handling of the main executive functions: volition, self-awareness, planning, response inhibition, response monitoring and attention. |
Active Comparator: Gait training alone
The control group will perform a gait training alone, without associated tasks (single-task condition).
|
Behavioral: Gait training alone
The training will consist of 10 sessions, two times per week for five weeks, and consists of 30 minutes of global exercises that involves stretching, muscle strengthen and axial mobility exercises, and another 30 minutes of gait training alone, without other tasks. |
- Dynamic Gait Index [ Time Frame: 05/2013 (Up to ten months) ]The scale assesses the ability to adapt the gait during motor tasks with different demands.
- Montreal Cognitive Assessment [ Time Frame: 05/2013 (Up to ten months) ]This scale was developed in order to detect mild degrees of cognitive impairment. The instrument assesses different cognitive domains such as attention and concentration, executive functions, memory, language, visuo-constructive skills, calculations, and orientation.
