Neuropathic Pain Intervention With tDCS in Brazilian Military Personnel (NeuBRAIN Trial)
Sponsor: Hospital da Polícia Militar de Goiás
Summary
This project protocol investigates the efficacy of transcranial direct current stimulation (tDCS) in treating neuropathic pain and improving sleep quality among Brazilian military personnel. Given the high prevalence of chronic pain and sleep disturbances in this population, and the limitations of current pharmacological treatments, our randomized, triple-blinded, sham-controlled trial explores the potential of tDCS as a non-invasive therapeutic intervention. The results of this study could have a significant impact on improving the well-being and performance of military personnel, while also reducing healthcare costs associated with long-term medication use.

Interventions
tDCS
This group will receive single-phase direct current with an intensity of 2 mA up. Electrodes with a size of 35cm² (5 x 7 centimeters) will be used. Electrodes will be placed on the scalp, fixed with elastic bands, and immersed in 10 to 12 mL of saline solution.
sham intervention
The device displays will be identical across active and sham groups, and to ensure blinding, an active current will be applied for 30 seconds at the beginning and end of the sham stimulation to mimic the sensation of the current ramp experienced in active stimulation. Stimulations of less than 3 minutes of tDCS do not induce cortical excitability effects, according to Nitsche and Paulus (2000), being safely inactive for the expected results.
