Experimental: experimental group - tDCS
The tDCS intervention occur at 10 sessions of intervention where electrodes are connected to head specifically in supplementary motor area placed at 2 cm in front of vertex.
The clinical stimulator (NeuroConn, Germany) provided the direct current using two silicon-sponge electrodes with a surface area of 35 cm2 (5 × 7cm) embedded in a saline-soaked solution.
Immediately after 13 minutes of tDCS application, patient was submitted to gait training three times a week during 4 weeks with visuals cues.
The patients were asked to walk along at a 7 meters rubber carpet to at different speed, forward and backward gait, side walk during thirty minutes with three intervals of two minutes.
The patient may be at on state of drug administration and the training is applied by another physiotherapist.

Schein-Komparator: Control group (tDCS sham)
The sham character is ensured by the stimulation time, once the device is programmed to turn off 30 seconds after the beginning of stimulation.
The current is switched in ascending ramp mode for 10 seconds until 2 mili ampere and a descending ramp similar also for 10 seconds will be used until the end of stimulation.
The sham stimulation is commonly perceived by the patient as the actual treatment and all procedures for the application of the technique should be similar to those adopted for the active stimulation.
Immediately after tDCS stimulation, the gait training consisting of a protocol based on sensory cues for 30 minutes is administered three times a week for four weeks.
Sham stimulation will be held for 30 seconds in order to mimic the perceived lowering effect of ramp current.

This outcome will be measure in three different moments of evaluation and at all interventions (sessions) days - before and after intervention.
Beyond these evaluations, the voluntairs will be evaluate at: T1- before ten sessions; T2- Immediately after ten sessions and T3- after a period of 1 month without intervention.

Change on Balance
Zeitfenster: This outcome will be measure before ten sessions, 1 and 2 months after ten session
|
Berg Balance scale (BBS) is measured asking to the patient for change posture in sit position for search balance during transferences and standing with one foot at single or double support, with open and closed eyes, narrow support base body, rotation around the own body axis; take up an object at floor and others.
This outcome is done using a scale with scores range from 0 to 56.
