在 UGT 期间分析步态生物力学的大多数先前研究在生物力学评估中忽略了行走速度的重要性。因此，本研究调查了 NWS 和 FWS UGT 中发生的下肢生物力学变化，目的是揭示与速度相关的影响。
在 Nws 和 Fws 的 Ugt 期间， 在下垂平面的臀部、膝盖和脚踝关节的 ROM 上发现了显著差异。我们的发现显示，在 FWS 的 UGT 期间，下垂平面中 3 个关节的 ROM 与 NWS 相比更大。这些结果与先前关?...

人类运动被认为是一个极其复杂的过程，需要用多学科的方法1，2来描述。最具代表性的方面是生物力学方法的步态分析。人类步态旨在维持从启动到终止的进展，在位置运动中应保持动态平衡。虽然步态终止（GT）作为步态的子任务被广泛研究，但它受到的关注较少。麻雀和Tirosh3在其审查中将GT定义为运动控制期，当双脚根据位移和时间特征停止向前或向后移动时。与稳态步态相比，GT的执行过程要求对神经肌肉系统4的姿势稳定性和复杂的整合与合作进行更高的控制。在GT期间，身体需要迅速增加制动冲动和减少推进冲动，以形成一个新的身体平衡5，6。计划外的步态终止（UGT）是对未知刺激6的压力反应。当面对需要突然停止的意外刺激时，最初的动态平衡将会被打破。由于需要持续控制身体的质量中心（COM）和反馈控制，UGT对姿势控制和稳定性3，7提出了更大的挑战。
据报道，UGT是导致跌倒和受伤的一个重要因素，特别是在老年人和平衡障碍患者3，8。在 UGT9期间，更快的步行速度可能导致电机控制进一步下降。Ridge 等人10调查了 UGT 期间儿童在正常行走速度 （NWS） 和快速行走速度 （FWS） 期间的峰值关节角度和内部关节时刻数据。结果显示，与首选速度相比，膝盖弯曲角度和延长时刻的速度更大。他们指出，加强下肢关节周围的相关肌肉可能是在GT期间预防伤害的有用干预。
虽然在稳态步态下行走速度对下肢生物力学特征的影响已得到广泛研究，但不同行走速度下的UGT生物力学机制有限。据我们所知，只有三项研究特别评估了健康个体在速度效应9、10、14方面的表现。然而，这些研究的受试者主要是14岁老人和10岁儿童，UGT期间年轻人的生物力学机制仍不明朗。下肢运动学和植物压可以提供运动生物力学的精确分析，这些也被认为是临床步态诊断的关键组成部分15，16。例如，Serrao等人17日使用下肢运动学数据来检测小脑厌食症患者与健康患者在突然停止期间的临床差异。此外，与计划中的步态终止 （PGT） 相比，UGT 期间横向骨体中较大的峰值压力和力可以观察到7，这可能与更高的伤害风险相关。
因此，探索GT的生物力学机制可以为伤害预防和进一步的临床研究提供见解。这项研究提出了一个协议，以调查在GT期间，在不同行走速度下年轻人的任何生物力学变化。据推测，随着行走速度的提高，参与者在 UGT 期间将表现出不同的下肢生物力学特征。

lower-limb biomechanical characteristics associated with unplanned gait termination under different walking speeds

意外刺激导致的盖特终止是日常生活中的常见现象。这项研究提出了一个协议，以调查在计划外步态终止（UGT）期间在不同的行走速度下发生的下肢生物力学变化。15名男性参与者被要求分别以正常行走速度（NWS）和快速行走速度（FWS）在人行道上表演GT。应用运动分析系统和植物压力平台收集下肢运动和植物压力数据。配对采样 T 测试用于检查下肢运动学和植物压力数据在两个行走速度之间的差异。结果显示，与 NWS 相比，在 FWS 的 UGT 期间，下垂平面的臀部、膝盖和脚踝关节的运动范围更大，前脚和脚跟区域的植物压力也更大。随着行走速度的提高，受试者表现出不同的下肢生物力学特征，显示FWS与更大的潜在伤害风险相关。

15 个科目的 NWS 和 FWS 的平均和 SD 值分别为 1.33 ± 0.07m/s 和 1.62 ± 0.11m/s。
图 3 显示在 Nws 和 Fws 的 Ugt 期间， 下垂平面中臀部、膝盖和脚踝关节的平均 ROM 。与 NWS 相比，FWS 的三个接头的 ROM 显著增加（p&lt：0.05）。详细说来，臀部、膝盖和脚踝关节的ROM从22.26±3.03， 29.72 ± 5.14 和 24.92 ± 4.17 到 25.98 ± 2.94， 31.61 ± 4.34 和 28.05 ± 5.59 （图 3</str...
