Electrode displacements. The 1-day postoperative (Near-term: Red) and 3-weeks postoperative (Long-term: Green) electrode locations were compared to the preoperative plan (Planned: Blue) (Wilcoxon Signed-Rank Test p < 0.05). A) Left electrode displacement, B) Right electrode displacement, C) Left and right comparison in near-term, and D) Left and right comparison in long-term. Significant anterior direction shift was observed in left long-term compared to left planned and near-term. Significant right, anterior, and superior direction shift was observed in right long-term compared to right planned and near-term. Electrode displacement in right hemisphere was significantly higher than left hemisphere in the superior direction for the near-term, and the right and superior directions for the long-term.
