Sequential Visual Isometric Pinch for Task (SVIPT). Participants squeezed a force transducer to control movement of an on-screen cursor. Participants were instructed to navigate the cursor as quickly and accurately as possible between a HOME position and 5 gates by alternating the force exerted onto the transducer. Subjects trained 4 blocks of 30 trials of the SVIPT (Training Day – Day 1) and then returned the following day and trained another 4 blocks of 30 trials of the SVIPT (Retention Day – Day 2). In all subjects, MEP amplitudes (black arrows) were measured before (Pre), immediately after (0 min, P1), and at 5 min increments up to 25 min after application (P2-P6) of 7 min of AtDCS (grey ray). This was assessed immediately after training on the first day (occlusion), then on a separate day but without motor training (Baseline).
