tDCS and Its Therapeutic Effects in CK Fever

One of the major challenges faced by researchers working in the field of rehabilitation science is the ability to provide integrative approaches to the use of clinical practice. In this context it becomes increasingly necessary to construct investigative approaches, so that they can reach clinical practice in a shorter period of time,since the large volume of information produced globally does not impact in the short or medium term on new therapeutic recommendations. Among the various chronic painful entities, there is chikungunya fever as a highlight for having a rich clinical chronology in relation to pain. Its therapy is used done by drugs in almost all national and international consensuses, therefore therapy against pain in chikungunya fever is limited during the rehabilitation process. It is very important that the science of rehabilitation enhances methods of noninvasive brain modulation that enable, through the excitation or inhibition of specific cortical areas to produce pain inhibiting effects, providing a simple and low cost treatment to the clinical routine.Technological advances and non-invasive techniques to modulate brain function have been developed, for instance, Transcranial Direct Current Stimulation (tDCS).

The objective of the present project is to present the tDCS as a new modality of physical rehabilitation for the patient with chronic pain resulting from chikungunya fever. The purpose of the study is to present physical, behavioral and social results of the application of tDCS in chikungunya fever, suggesting an improvement in the quality of life and functional status of the individual.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Laboratory or medical diagnosis of chikungunya fever, being in the chronic phase of the disease, intellectual and physical capacity preserved for conducting research tests.

Exclusion criteria

  • History of seizures or epileptic disease, pregnancy, states associated with other previously diagnosed rheumatic diseases such as rheumatoid arthritis, gout and lupus, under 18 years and over 65 of age, patients with signs of severity and/or indication for hospitalization.

Treatment and study plan

Transcranial Direct Current Stimulation

Device

For electrode placement, the criteria used by the 10/20 electroencephalography system will be obeyed and the electrodes will be positioned area C3 for the anode and Fp2 (contralateral supraorbital area) for the cathode electrode. A constant current of 2mA will be applied for 20 minutes.

Sham Transcranial Direct Current Stimulation

Device

For electrode placement, the criteria used by the 10/20 electroencephalography system will be obeyed and the electrodes will be positioned area C3 for the anode and Fp2 (contralateral supraorbital area) for the cathode electrode, but the stimulator was turned off after 30 seconds of stimulation. Therefore, patients in the sham group felt the initial itching sensation but received no current for the rest of the stimulation period.
