An interventional study of Transcranial direct current stimulation in Pain Processing in Healthy Volunteers, sponsored by Universidad Rey Juan Carlos. Completed at 1 site in Spain. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-10-30.
Sponsored by Universidad Rey Juan Carlos · Not applicable, Interventional, and Treatment
The purpose of this study is to evaluate the effects of a direct current applied transcranial over two cortical areas on healthy volunteers' pain processing.
Universidad Rey Juan Carlos is the lead sponsor of 111 studies on the registry; 22 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
A 20 minutes 1mA direct current stimulation over left M1.
Device: Transcranial direct current stimulation
A 20 minutes 1mA direct current stimulation over left M1 and 1mA direct current stimulation over left DLPFC.
Device: Transcranial direct current stimulation
A 20 minutes sham stimulation where the device only is working first 30s and last 30s of the intervention and have a 10 seconds fade out in intensity at each ramp.
Device: Transcranial direct current stimulation
Direct current application over the scalp to stimulate and change the excitability of the cortical areas underneath the electrodes (in this case left primary motor cortex and left dorsolateral prefrontal cortex).
Conditioned Pain Modulation
Pain pressure threshold change after a painful ischemic stimulus
Time frame: Pre-intervention and immediately after treatment
Pain pressure algometer temporal summation
Change in pain perceived between the first and tenth painful pressure stimulus
Time frame: Pre-intervention and immediately after treatment
Pain pressure threshold
Measurement of pressure applied until the perception of pain
Time frame: Pre-intervention and immediately after treatment
Pain pressure tolerance
Measurement of maximal painful pressure tolerate using a pressure algometer
Time frame: Pre-intervention and immediately after treatment
Neural mechanosensitivity
Measurement of range of motion achieved until the perception of tension
Time frame: Pre-intervention and immediately after treatment
Cold hyperalgesia with a cold pack
Pain rated in a visual analogue scale after 10 seconds of a cold stimulus
Time frame: Pre-intervention and immediately after treatment
Isometric grip strength
Maximal pressure achieved in a isometric gripping task
Time frame: Pre-intervention and immediately after treatment
