| Outline of Final Research Achievements |
We conducted measurements twice, at intervals of one to two years, on standing balance using a balance assessment device with handrails, ultrasonic assessments of lower leg muscle thickness, and balance evaluations among community-dwelling elderly individuals. Low grip strength and slow walking speed were the primary classification factors for the pre-frail group. As a result, no differences were found in standing balance ability (center of pressure sway, force applied to handrails) or lower leg muscle thickness between the healthy group and the pre-frail group. However, in the pre-frail group, there was a negative correlation between total trajectory length during both open-eye conditions with and without handrails and the thickness of the calf muscles. These results suggest that in the pre-frail stage, along with a decrease in calf muscle thickness, there is an increase in body sway during standing with eyes open, regardless of the presence of handrails.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、フレイル評価基準によって健常者群、プレフレイル群に分類された高齢者を対象にして、立位保持能力、下腿筋厚、及びバランススケールを縦断的に測定した（半年～１年ごとを３年間）。そして、各群ののデータにより、フレイルの予防に立位保持能力と下腿筋筋厚を客観的に捉え、理学療法介入の適切なタイミングを考察した。本研究の結果では、経時的にタイムアップアンドゴ（TUG)テストのタイムの増加、手すりを使った立位保持時の足圧中心の総動揺の増加、そして腓腹筋の筋厚の減少が最も注意するべき項目であり、介入するタイミングであると示唆された。
