| dc.description.abstract | 步行於移動平面而失去平衡是跌倒的主要原因之一，且極可能造成嚴重的後果。建立步行於不同速度之移動平面，下肢的完整下肢運動學與穩定度分析將有助於設計預測或預防跌倒之方法，因此本研究發展一可量測力量之跑步機，旨在藉此跑步機，建立年輕人步行於不同速度之移動平面時之下肢力動學資料進而用以評估其穩定性，以瞭解步行於不同速度之移動平面時之動作的穩定性及其調控機制。本研究利用一配有五台紅外線攝影機之動作分析系統量測十位健康年輕人步行於不同速度之移動平面時之全身運動學資料，並利用自行研發之測力跑步機量測其運動過程中之地面反作用力，接著以逆向動力學分析獲得終端點參數、骨盆、下肢關節角度、力矩、以及全身質量中心與足底壓力中心的運動，並以單因子變異數分析，比較步行於不同速度之移動平面的生物力學差異。本研究成功的運用校正後的測力跑步機完成一套人體動作分析研究，由比較過去文獻以及實驗的各項數據結果直接驗證測力跑步機已經可以正式的運用在未來任何的人體動作研究上。健康年輕人藉由改變下肢關節角度及角速度變化來因應移動平面速度的增加，並利用調節身體質量中心位置，速度，及加速度來維持平衡控制。當比較身體質量中心與足底壓力中心之間的夾角及角速度方面，不論是前後方向或者是左右方向，振幅皆大於行走至靜止平面之相對應瞬間的數值。顯示需要在速度增加時作必要的調節，尤其是在單腳支撐及雙腳支撐轉換時，其較小的向內身體質量中心及足底壓力中心之角度，提供神經肌肉骨骼系統較多的餘力來控制速度增加所造成的挑戰。關於動作執行之變異性來表示穩定度之研究，顯示隨著移動平面的速度增加，行走於移動平面之步態過程中，健康年輕人之動作不穩定性，主要發生在前後方向，且在行走於移動平面之步態過程中，健康年輕人作了一些下肢關節運動的改變，以至於關節間的協調也都有顯著的改變。使之能穩定地應付速度所造成的負荷，藉由關節間協調之型態及變異性，來控制動態平衡。 | zh_TW |
| dc.description.abstract | Instrumented treadmill allowing collecting ground reaction force during a large number of successive cycles make possible for the method to analyze motor control errors defined as movement variability. Since dynamic stability is closely related to variability, the observed variability during dynamic tasks can thus offers insight into neuromuscular control mechanisms. In the current study, an instrumented treadmill were developed providing vertical ground reaction force and centre of pressure (COP). Being synchronized together with a motion capture system, a complete kinematic and dynamic stability analysis were performed on 10 young subjects during treadmill walking to provide quantified biomechanical data of gait performance. Gait variables, joint angles as well as motion of the centere of mass (COM) and pelvis were calculated. The differences between eight speed conditions were analyzed using one-way ANOVA (12333 | en |
