About

The main objective of this research is to evaluate and quantify hypoalgesic effects caused by imagination and observation with or without the presence of transcranial direct current (tDCS) in healthy participants. The secondary objective of this research is to evaluate the possible relationships between hypoalgesic effects and different physical and cognitive variables such as the ability to generate motor mental images, mental chronometry and levels of physical activity.

45 participants in 3 patient groups, including a placebo group

transcranial direct current plus Brain training tools

Experimental group

Description:

20 minutes of transcranial direct current stimulation along with the application of motor imagery and action observation

Treatment:

Device: Sooma transcranial direct current stimulation device plus Brain training tools

Placebo transcranial direct current plus Brain training tools

Placebo Comparator group

Description:

A placebo intervention of direct transcranial stimulation being active during 15 seconds and then it will be turned off the rest of the time until 20 minutes. This group will also carry out the training of action observation and motor imagery.
