VOR gain for medial (PICAM) and lateral (PICAL) PICA stroke based on the involvement or non-involvement (PICAL) of the nodulus or uvula (PICAM). The VOR gain for PICAM tended to increase more than PICAL in all three semicircular canals; however, statistical significance was observed only in the ipsilesional horizontal semicircular canal (*p-value < 0.05, Mann–Whitney U-test).
