Study Overview
Brief Summary
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.

Arms & Interventions
transcranial direct current plus Brain training tools
20 minutes of transcranial direct current stimulation along with the application of motor imagery and action observation
Intervention: Sooma transcranial direct current stimulation device plus Brain training tools (Device)
Placebo transcranial direct current plus Brain training tools
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.
Intervention: Placebo Sooma transcranial direct current stimulation deviceplus Brain training tools (Device)
Brain training tools in isolation
This group will act as a control, they will only carry out the training of action observation and motor imagery.
Intervention: Brain training tools in isolation (Behavioral)
Outcomes
Primary Outcomes
Pressure pain threshold
Time Frame: Change in Pressure pain threshold just before the start of the intervention, immediately at the end of the intervention and 15 minutes after the end of the intervention
Pressure pain threshold has been defined as the minimal amount of pressure at which a sense of pressure first changes to pain or discomfort
Secondary Outcomes
- The degree of physical activity(Just before the start of the intervention)
- Ability to generate motor images(Just before the start of the intervention)
- Mental Chronometry(Just before the start of the intervention)
