| Outline of Final Research Achievements |
In patients with peripheral vertigo,it is hard to evaluate the affected side and severity of ear with postural tests aside from ocular motor tests. We examined whether new type of postural tool as measured by weight bearing detects the lesioned side and severity. Patients with dizziness received the weight bearing test in the static standing. We calculated the laterality of weight bearing between left and right. The laterality was not significantly higher in patients with peripheral vertigo than in those with other etiologies. However peripheral vertigo subjects with unilateral vestibular disturbance (UVD) determined by caloric paresis showed about 2 times higher laterality than those without UVD.
These results suggest that the laterality between left and right weight bearing indicate the affected side and severity of vestibular functional disturbance. The weight bearing test might be useful a postural diagnostic tool in patients with peripheral vestibular disturbance.

| Academic Significance and Societal Importance of the Research Achievements |
本研究において考案された下肢荷重平衡テスト（仮称）が、身体の偏倚性を正確に定量化して、前庭機能の活動性の左右差を検出する可能性が示唆された。本検査が実用化されれば、将来的には前庭障害の体平衡機能を調べるのに有用な検査法として一般診療で汎用される期待がある。
