Numerical Modelling of Trascutaneous Spinal Direct Current Stimulation (tsDCS)

This work estimates the distribution of the current density on the spinal cord due to transcutaneous spinal direct current stimulation. We used computation method applied to realistic human model of different age and sex and we compared three different electrode montages. Data showed that the current density tends to be primarily directed longitudinally along the spinal cord with the region of higher amplitude influenced by the reference electrode position, while on transversal sections the J amplitude distributions were quite uniform.
