“…In a previous study, to confirm the manner in which the subject adjusted the COP while tracking a visual target, principal component analysis was employed. As a result, it was determined that the tracking axis of the AP BTT was not parallel to the Y-axis [11]. We thought that this result could be influenced by the dominant foot of the subjects to some extent.…”

ConclusionThe antero-posterior (AP) body tracking test (BTT) showed that the dominant foot could affect the tilt angle of the sway movement, delineated by primary component analysis. Differences associated with the dominant foot could represent the difference in space perception of each person.ObjectivesTo examine whether the dominant foot could affect the postural control mechanism using the BTT. MethodsNinety-seven healthy participants enrolled in the study were classified into right-foot and left-foot dominance groups, and their performances were compared. For the BTT, each participant stood on a stabilometer and caught the movement of a visual target moving vertically (anterior-posterior) or horizontally by the center of pressure movement, displayed on a 14-inch screen monitor at 100 cm in front of the subject. The mean displacement angle of the obtained stabilogram was evaluated by principal component analysis.ResultsThe AP BTT in the right-foot dominance group showed a clockwise tilt with a mean displacement angle of 3.022 ± 3.761°, whereas the group with left-foot dominance had a modest counter-clockwise tilt with a mean displacement angle of –0.694 ± 4.497°. This difference was found to be significant by the independent t test (p < 0.0001). In the lateral BTT, the mean displacement angles were not significant.
