| Outline of Final Research Achievements |
This study aimed to maintain and improve gait function essential for independent living in the elderly by developing a classification system for standing postures and intervention methods. First, posture types were classified based on pelvic tilt angles and knee joint angles. Furthermore, a method for estimating pelvic tilt angles was developed to enable accurate posture classification by measurers without specialized skills.
Utilizing these techniques, large-scale measurements of standing posture and physical function were conducted on community-dwelling elderly individuals. The results revealed differences in the determinants of gait function for each posture type. Consequently, the study demonstrated the necessity of developing intervention programs that address the individual characteristics of the elderly according to their standing posture types.

| Academic Significance and Societal Importance of the Research Achievements |
学術的意義として，立位姿勢を骨盤傾斜角度（前傾・後傾）および膝角度（屈曲・伸展）で４タイプに分類した際，歩行機能に有意な差が認められないこと，また歩行速度の規定要因がタイプごとに異なることが明らかになった点が挙げられる。さらに，骨盤傾斜角度の推定が触診やレントゲン等の特別な技術・機器を用いずに可能になった点の社会的意義も大きいと考えている。
