NCT04127253

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.

Outcome Measures

Primary Outcomes (1)

  • Pressure pain threshold

    Pressure pain threshold has been defined as the minimal amount of pressure at which a sense of pressure first changes to pain or discomfort

    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

Secondary Outcomes (3)

  • Ability to generate motor images

    Just before the start of the intervention

  • Mental Chronometry

    Just before the start of the intervention

  • The degree of physical activity

    Just before the start of the intervention

Study Arms (3)

transcranial direct current plus Brain training tools

EXPERIMENTAL

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

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

Placebo transcranial direct current plus Brain training tools

PLACEBO COMPARATOR

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.

Device: Placebo Sooma transcranial direct current stimulation deviceplus Brain training tools

Brain training tools in isolation

SHAM COMPARATOR

This group will act as a control, they will only carry out the training of action observation and motor imagery.

Behavioral: Brain training tools in isolation

Interventions

This group will carry out an observation training of actions and motor imagery in combination with the stimulation of the transcranial direct current.

transcranial direct current plus Brain training tools

This group will carry out an observation training of actions and motor imagery in combination with the placebo stimulation of the transcranial direct current, where it will be acrtivo during 15 seconds and then it will be turned off during the rest of the intervention.

Placebo transcranial direct current plus Brain training tools

This group will act as a control, they will only carry out the training of action observation and motor imagery.
