Study design schematic. During the first visit, initial evaluations (UEMS, AIS) and questionnaires (SCIM III, VAS) were completed. During the 20-minute intervention period, participants received either 1 or 2mA of a-tDCS or sham. Neurophysiology and muscle strength measures were recorded at 3 time points (pre, post, follow-up). Abbreviation: SCIM III, Spinal Cord Independence Measure version III.

Electric field (normative component) generated by the montage (+C3, -AF8) using Pi electrodes (3.14cm2 silver/silver chloride electrodes). Positive/negative values indicate anodal/cathodal stimulation (normative component of the electric field pointing inward/outward at the cortical surface).
