Our results evaluating the correlations between nasal mucosal and serum levels of antigen-specific IgE indicate that IgE produced in the nasal mucosa affects the IgE levels in the serum, especially the cedar pollen-specific IgE.

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.

Body Tracking Test (BTT) is a testing method of the dynamic body balance function wherein movement of the center of gravity in accordance with a moving visual target stimulus is examined to evaluate the tracking function of the body. The objects were the patients who were diagnosed as having vestibular neuronitis at the Department of Otolaryngology in Toho University medical center Sakura hospital, and were undergoing hospital treatment. Lateral BTT was performed in 31 subjects, and antero-posterior (A-P) BTT in 45 subjects. Although gaze nystagmus was noted, inspection was enforced when a standing position posture was possible. In lateral BTT, the average (cm/second) horizontal direction body sway speed was compared, however, no clear lateral difference was noted. In the antero-posterior (A-P) BTT, it inquired using the direction body sway average center displacement (cm) of X. Deviation was seen by the affected side in stabilometry. Deviation was seen by the unaffected side in the antero-posterior (A-P) BTT. This phenomenon differs from the deviation pattern until now and is considered to involve participation of the higher centers.
