| Outline of Final Research Achievements |
A detailed analysis of the involvement of anti-gravity muscles,and how posture is controlled in healthy adults was conducted and the differences in posture control between adults and older people were examined. The body equilibrium function test and electromyography were synchronized and simultaneously recorded to measure EMG of anti-gravity muscles. The subjects were 24 healthy adults and 19 older people aged 65 years or older.
It was found that as people aged, their ability to maintain posture decreased and muscle activity increased. There was a left-right difference in the rate of muscle activity in holding the posture, which was thought to be related to the other non-dominant foot. In the dynamic body balance function test, older adults who were better at tracking made particularly good use of their gastrocnemius.It was found that it is important to train the inferior triceps muscle, including the gastrocnemius, to prevent falls in the older adults.

| Academic Significance and Societal Importance of the Research Achievements |
加齢性前庭障害は、2019年にBarany SocietyがPresbyvestibulopathy（PVP）としてその診断基準を策定した疾患の日本語名である。PVPは高齢者において不安定感，歩行障害，繰り返す転倒などの慢性の前庭症状を呈し，臨床検査で軽度の両側前庭機能障害を示す症候群と定義される。本研究は、重心動揺検査、動的体平衡機能検査を用いており、姿勢保持障害，不安定感についての他覚的検査として重要である。
また、高齢社会を迎えている現在、転倒・転落は社会的な問題である。本研究により転倒・転落の予防にもつなげていくことが可能であり、社会的意義は大きいと考える。
