Neuromodulation on Motor Function in Parkinson's Disease
2014年9月24日 更新者：Adriana Carla Costa Ribeiro Clementino、Universidade Federal de Pernambuco
Transcranial Direct Current Stimulation (tDCS) Associated With Gait Training in Improving Motor Function in Parkinson's Disease
The aims of the present study was to analyze the effect of consecutive sessions of Transcranial direct current stimulation associated to kinesiotherapy about gait performance of Parkinson' s disease.
For this, the primary outcome was evaluation of gait performance by means of space and temporal parameters as speed (meter/second ), stride frequency (steps/min) and stride length (m).
The secondary outcome is motor cortex excitability which is analyzed by means of single pulse transcranial magnetic stimulation (TMS) intends to determine: motor evoked potential amplitude (MEP) and rest motor threshold (rMT).

详细说明
This study consist by interventions involving screening followed by evaluation, where volunteers were subjected to the many tests: history, session III of the Unified Scale Modified Parkinson's Disease - Unified Parkinson 's Disease Rating Scale, Ten meters walk test - Walk Test 10 meters and shoot gait, (using Studio Version 8 software).
On the same day, the subjects underwent assessment of brain excitability to determine motor threshold and amplitude of the motor evoked potential (MEP).
The randomization of the volunteers was conducted by an external search through opaque envelopes ordered according to a random distribution.
The subjects were divided into two groups : control group , this group submitted to Transcranial Stimulation sessions a sham Continuous Current (sham tDCS) and gait training , and Experimental group, subjected to the stimulation by Transcranial Direct Current sessions (active tDCS ) and gait training.

实验性的：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.

假比较器：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.
