Summary

The purpose of this study is to investigate the modulatory effect of a novel tDCS configuration on the pain sensitivity in healthy subjects.

Detailed description

The purpose of this study is to investigate the modulatory effect of a single session 20 min anodal primary motor cortex (M1) and cathodal primary somatosensory cortex (S1) transcranial direct current stimulation (tDCS) on the pain sensitivity on the descending part of musculus trapezius in healthy young adults.

Conditions

• Healthy

Interventions

Type	Name	Description
DEVICE	Active tDCS	Using the 2-channel neuro-stimulator Sooma tDCS equipment we provide 20 minutes of 2 mA anodal stimulation of the primary motor cortex (M1) with the cathode located over the right primary somatosensory cortex (S1).
DEVICE	Sham tDCS	Using the 2-channel neuro-stimulator Sooma tDCS equipment we provide a sham stimulation with the anode place over the primary motor cortex (M1) and cathode located over the right primary somatosensory cortex (S1). The sham stimulation consists of 30 seconds of stimulation ramping up to a maximum of 2 mA, then 19 minutes of the device providing no stimulation and then ramping down from 2 mA intensity to 0 in the last 30 seconds. This configuration is designed to mimic the sensory experience of active tDCS.
