Clinical Trial Summary

Several studies have demonstrated that direct currents delivered through the skin at the level of the lumbar spinal cord can influence spinal cord function. In human volunteers, anodal lumbar 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.

Description:

The investigators will compare the effects on the nociceptive processing of healthy volunteers of cervical and lumbar tsDCS. This study will be a double-blinded, sham-controlled, cross-over trial. Each participant will undergo two experimental sessions (anodal cervical tsDCS and sham lumbar tsDCS vs. sham cervical tsDCS and anodal lumbar tsDCS), separated by at least one week.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in contact-heat evoked potentials amplitude	N2/P2 amplitude	Change from Baseline, at 15-minutes after the end of stimulation
Secondary	Change in intensity of perception to contact-heat nociceptive stimuli	Difference in temperature (°C) needed to elicit a pain sensation of similar intensity in the upper and lower limb	Change from Baseline, at 15-minutes after the end of stimulation
Secondary	Change in temporal summation of pain	Wind-up ratio (WUR) to mechanical pinprick stimuli	Change from Baseline, at 15-minutes after the end of stimulation
Secondary	Change in intensity of perception to mechanical pinprick nociceptive stimuli	Numerical rating scale (0-100)	Change from Baseline, at 15-minutes after the end of stimulation
