简要总结
This study consists of a randomized, double-blind, clinical trial with two months' duration of follow-up. The variable used was the VAS for pain, considering the values of any difference between the data before and after stimulation.
详细描述
The average between the analyzed values was 1.20, with a standard deviation of 0.84, taking into account a type I error of 5%, a type II error of 10% and a power of 80%. From the sample calculation was found an n = 10 for each group. The sample is amplified in order to avoid possible effects of dropout ending with a n = 15 in each group with a total N = 45.
Randomization was performed by a blinded therapist using sealed envelopes for each individual. The subjects will be divided into three intervention groups: tDCS (tDCS - DC stimulator, Neurocom, Germany) / AE Group, in which will receive active intervention of aerobic exercise training and active tDCS intervention. AE group, which will receive active intervention of aerobic exercise and placebo tDCS. And tDCS group, which will receive placebo AE and active intervention for tDCS.
Participants will be blinded to the intervention groups as well as therapists involved in the evaluation process.
The evaluation methods were carried out one week before the beginning of the intervention (baseline) for all variables. After the first week of intervention (neuromodulatory period) was performed ratings for level of cortical excitability (T1), and after the end of the one month period of intervention for all variables (T2). Follow-up evaluations were conducted one month (T3) and two months (T4) after the end of the intervention period."

结局指标
主要结局
Change in Visual Numeric Scale (VNS)
时间窗: Up to 2 months
Pain intensity is measured using a scale from 0 to 10. A straight 10 cm line is displayed for the subject enumerated from zero to 10, where zero represents no pain and 10 the worst pain possible. Subjects should mark the number that most represents the symptom of pain at the moment. Outcome will be measured 24 hours after each intervention session, after 1 month of the end of protocol and 2 months after the end of protocol for evaluation of long term effects.
