Transcranial Direct Current Stimulation (tDCS) in the Primary Motor Cortex in Healthy Individuals

October 31, 2019 updated by: Roy La Touche Arbizu, Universidad Autonoma de Madrid

Transcranial Direct Current Stimulation (tDCS) in the Primary Motor Cortex and Its Effects on Sensitivity, Pressure Pain Threshold, and Electromyographic Activity in Healthy Individuals: A Quasi-experimental Single-blind Sham-controlled Trial

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: transcranial direct current stimulation
This group received brain training through transcranial direct current for 20 minutes.
PLACEBO_COMPARATOR: Sham transcranial direct current stimulation
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pressure pain threshold through an algometer
Time Frame: Change in pressure pain threshold immediately at 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
Change in pressure pain threshold immediately at the end of the intervention
Tactile acuity threshold
Time Frame: Change in tactile acuity threshold immediately at the end of the intervention
Tactile acuity threshold is an important variable to know the somatosensory state and Von Frey monofilaments and Aesthesiometer were used
Change in tactile acuity threshold immediately at the end of the intervention
Muscle recruitment through electromyographic activity
Time Frame: Change in electromyographic activity immediately at the end of the intervention
The activity of surface electromyography (sEMG) during an isometric maximal voluntary contraction was measured in the biceps brachii and rectus femoris.
Change in electromyographic activity immediately at the end of the intervention
