简要总结
Several studies have demonstrated that direct currents delivered through the skin at the level of the low-thoracic spinal cord can influence spinal cord function. In human volunteers, anodal low-thoracic transcutaneous spinal direct current stimulation (tsDCS) alters spinal processing of nociceptive inputs. Whether cervical tsDCS is able to do the same is less well known. In this double-blinded, sham-controlled and cross-over trial, the investigators will compare the effects on the nociceptive processing of healthy volunteers of cervical and low-thoracic tsDCS.
详细描述
The investigators will compare the effects on the nociceptive processing of healthy volunteers of cervical and low-thoracic tsDCS. This study will be a double-blinded, sham-controlled, cross-over trial. Each participant will undergo three experimental sessions (anodal cervical tsDCS and sham thoracic tsDCS vs. sham cervical tsDCS and anodal thoracic tsDCS vs. sham cervical tsDCS and sham thoracic tsDCS), separated by at least one week.
