Intervention / Treatment
Detailed Description
Background: Patients with Parkinson's disease have difficulty performing a dual-task, a condition present in everyday life. It is possible that strategies such as Transcranial Direct Current Stimulation can be associated with motor training enriched with dual-task and cognitive training to improve the performance of two concurrent tasks. It is currently unclear whether specific tasks and clinical conditions of PD patients have different results after the intervention. Therefore, the proposed randomized controlled trial will examine task-dependency in enhancing the effects of tDCS-linked rehabilitation training on PD and the relationships between baseline outcomes in responders and non-responders to therapy.
Discussion: This study will evaluate the effectiveness of an intervention protocol with transcranial direct current stimulation, dual-task training and cognitive training in patients with Parkinson's disease. The study will also highlight whether the clinical factors and variability between individuals that could interfere in the training of a specific task and influence the therapeutic effect.

- associated diseases of the peripheral or central nervous system
- undergoing physical therapy at another location
- inability to walk 10 meters
- presence of important dyskinesia that prevents the participant from sitting in a chair

---|---|
Active Comparator: Active group
In the group G1 will be administered: tDCS active + dual-task motor training + cognitive training.

Both groups will undergo the motor training where only the type of received electric current is varied (active or simulated sham type) associated cognitive training.
The twelve sessions will be performed in three sessions per week for 30 minutes.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Changes dual-task gait speed by the Auditory Stroop Task
Time Frame: [Baseline, after 04 weeks]
|
For this outcome, the Auditory Stroop Task participants will be asked to walk while listening to words spoken loudly and softly and indicate if the volume heard was loud or low, irrespective of the word pronounced.
|
[Baseline, after 04 weeks]

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in executive functions assessed by Wisconsin Card Sorting Test (WCST)
Time Frame: [Baseline, after 04 weeks]
|
The Wisconsin Card Sorting Test (WCST) is a neuropsychological test of "set-shifting", i.e. the ability to display flexibility in the face of changing schedules of reinforcement.
A number of stimulus cards are presented to the participant.
The participant is told to match the cards, but not how to match; however, they are told whether a particular match is right or wrong.
The original WCST used paper cards and was carried out with the experimenter on one side of the desk facing the participant on the other.
The test takes approximately 12-20 minutes to carry out and generates a number of psychometric scores, including numbers, percentages, and percentiles of: categories achieved, trials, errors, and perseverative errors.
|
[Baseline, after 04 weeks]
|
Changes in executive functions assessed by Trail Making Test (TMT)
Time Frame: [Baseline, after 04 weeks]
|
The Trail Making Test (TMT) is a neuropsychological test of visual attention and task switching.
It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy.The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning
|
[Baseline, after 04 weeks]
|
Changes in executive functions assessed by Verbal Fluency Test
Time Frame: [Baseline, after 04 weeks]
|
The Verbal Fluency Test are a kind of psychological test in which participants have to produce as many words as possible from a category in a given time (usually 60 seconds).
This category can be semantic, including objects such as animals or fruits, or phonemic, including words beginning with a specified letter, such as p, for example
|
[Baseline, after 04 weeks]
|
Changes in executive functions assessed by Montreal Cognitive Assessment (MoCA)
Time Frame: [Baseline, after 04 weeks]
|
The Montreal Cognitive Assessment (MoCA) is a cognitive screening tool.
MoCA is composed of eight cognitive domains, which are scored within a range of 0 to 30 points (higher scores indicate better function): short-term memory; visuospatial skills; executive function; verbal fluency; attention, concentration and working memory; language; sentence repetition; and spatiotemporal orientation.
|
[Baseline, after 04 weeks]
|
Changes in motor functions assessed by Dynamic Gait Index (DGI)
Time Frame: [Baseline, after 04 weeks]
|
The Dynamic Gait Index (DGI) assess gait, balance and fall risk.
It evaluates not only usual steady-state walking, but also walking during more challenging tasks.
A four-point ordinal scale, ranging from 0-3. "0" indicates the lowest level of function and "3" the highest level of function (total score = 24).
|
[Baseline, after 04 weeks]
|
Changes in motor functions assessed by 10-meter walk test
Time Frame: [Baseline, after 04 weeks]
|
The 10-meter walk test to estimate gait speed by recording the average time the patient takes to cover a distance of 10m in three attempts
|
[Baseline, after 04 weeks]
|
Changes in motor functions assessed by Timed Up and Go (TUG) test
Time Frame: [Baseline, after 04 weeks]
|

|
[Baseline, after 04 weeks]
|
Changes in motor functions assessed by Kinematics of Gait

[Baseline, after 04 weeks]
|
Changes in motor function assessed by the Unified Parkinson's Disease Rating Scale - Part III (UPDRS - III)
Time Frame: [Baseline, after 04 weeks]
|
For this outcome, the Unified Parkinson's Disease Rating Scale - Part III will be used.
Section III provides an overall score for movement-related functions and activities (tremor, stiffness, gait, alternating movements, among others).
This section is made up of 33 items, which can range from zero (normal) to four (severe), with responses that are linked to commonly accepted clinical terms.
The higher the score, the greater the impairment of motor function.
