| Outline of Final Research Achievements |
In this study, we proposed a method to create a stability index for a fall avoidance strategy by simulating a fall avoidance strategy with bipedal support against slip and fall using a mechanical model. In addition, considering the decrease in joint range of motion with aging, we conducted simulations in which only the range of motion of a single joint was restricted in order to investigate which of the joints in the lower limb was affected by the decrease in stability. The results showed that the reduction in stability was greater when the ankle joint range of motion was restricted than when the other joints were restricted.

本研究で得られた成果は，滑り転倒時の回避動作における関節可動域の低下が転倒リスクに与える影響を力学モデルを用いて定量的に評価したものである．滑り転倒刺激を加えることで疑似的に実現象を再現し，回避動作の実験解析を行うだけでなく，その知見に基づき，力学モデルをベースとした順動力学シミュレーションを構築することで，下肢の関節可動域の低下が及ぼす安定性の減少量を理論的に解析している．そのため，今後はこの手法を用いることで，医師や専門家が個人の転倒リスクを屋内で安全かつ事前に判断することができ，可動域の低下量に基づいて最も効果的な訓練手法の選択，提示を行うことに応用可能である．
