The main aim of this study is to assess the short-term effects of active-tDCS (a-tDCS) on the M1 regarding sensorimotor variables such as discriminative sensation, pressure pain threshold and electromyographic activity compared with a sham-tDCS (s-tDCS) in healthy individuals. The main objective was to determine whether there were clinically relevant changes generated by tDCS and if they were superior to a sham intervention.

This group received sham brain training through transcranial direct current for 20 minutes. The current is active for 15 seconds and then switches off until the intervention is finished.

Pressure pain threshold through an algometer
Pressure pain threshold has been defined as the minimal amount of pressure at which a sense of pressure first changes to pain or discomfort
Time frame: Change in pressure pain threshold immediately at the end of the intervention
Tactile acuity threshold
Tactile acuity threshold is an important variable to know the somatosensory state and Von Frey monofilaments and Aesthesiometer were used
Time frame: Change in tactile acuity threshold immediately at the end of the intervention
Muscle recruitment through electromyographic activity
The activity of surface electromyography (sEMG) during an isometric maximal voluntary contraction was measured in the biceps brachii and rectus femoris.
Time frame: Change in electromyographic activity immediately at the end of the intervention
