在极使用的术语保持一致的重要性是该协议内的关键。特别是，为了正确极化技术，以及适当的极适当的步骤设置均保持不同研究的一致性非常重要。因此，一个特定的越野行走的组织指导和说明应遵循对等协议这一点。此外，特别是使用加速度计，使用一个完整的身体组三轴向显示器的重要的是要获得被检者的全身体运动的一个完整的了解（ 例如 ，步态和姿势），包括每一个特定的身?...

北欧式健走（NW）被认为是使用专门设计的杆1健身走的简单和安全的方式。有人建议，极提供增加稳定性，改善姿势，减少下肢关节的压力。然而，有限的或相互矛盾的证据存在关于关节负荷和姿势的调整。一方面，Schwameder 等 2，威尔森等 3和小泉等人在运动的措施和/或在地面反应，压缩减少量，并与他们的极行走研究的剪切力4报告的改进。另一方面，在制动/推进力和力矩的方面下降运动的措施，提高关节负荷已经报道由Hansen等 5，Stief 等 6和Hagen等 7而极行走。此外，改善姿势的调整的说法似乎已经消失了entirelŸ通过科研这点不支持。 与步态模式，不同的方法和设备发现了相反的结果类似在这方面的研究被用作良好。几项研究已经使用的3维动作捕捉系统4,6和数码摄像机2,5，全部用并入系统力板，以充分评估步态。而另外，其他研究评估采用北欧极化步态包括使用electrogoniometry 7，肌电图（EMG）8的其他手段，应变计安装在电线杆2,9。在这个协议中所使用的技术，提出了能够超过更多集中在较短的持续时间和单步态循环的替代技术来证明个人的北欧极化步态的更适当的表示（ 即重复步态周期）的特定优势。另外，该方法使用加速度计，一个有效的工具，这一点在越野行走的研究被稀疏使用。根据个别的研究项目的目标，如在本协议所述，特别是对短期和长期的持续时间步态此协议的应用程序可能是适当的情况下。要注意，这两个运动捕捉和加速度计是适于获得各种步态特征，包括重要的是：时空（ 如步幅长度，步态速度等 ），运动（ 例如 ，运动的范围），和动力学（ 例如力，输出功率等 ）的参数。 尽管使用这些不同设备的，只是时间短步态事件（ 即单步态周期）进行了评估，留下的问候问题，最好的评估持续时间较长的步态（ 即重复步态周期）。因此，对于开发和使用该技术的基本原理是基于第i塑造北欧极化步态的完整画面的mportance。 本研究的目的是双重的。第一，主要目标是确定和证实在步态和姿势的评估使用两个加速度计系统和三维运动捕获系统的过短和长持续时间。其次，我们的目标是确定对步态模式包括时间空间和动能措施以及老年人的姿势的调整越野行走手杖的整体效果。迄今为止，极少的研究主要集中在老成人NW对那些为已经出版，功能（ 即力量，平衡，柔韧性）代表了主要的结果变量。因此，需要对有关的步态可测量变量拐杖的作用，知识，能洞察随着年龄的增长极可以怎么玩到我​​们的步态模式。

substantiating appropriate motion capture techniques for the assessment of nordic walking gait and posture in older adults

越野行走（NW）已成为运动的安全和简单的形式，近年来，并且在研究该步态模式，各种数据收集技术已采用，每个阳性和阴性。这样做的目的是要确定NW对老年人成年步态和姿势的影响，并确定在短期和长期持续时间分析不同的数据收集系统的最佳利用。 NW和正常行走时步态和姿势在17名健康的老年人进行了评估（年龄：69±7.3）。参加演出的6分钟步行试验（6MWT）两项试验（1极点（WP）和1个无杆（NP））和5米之遥（3 WP和3 NP）6试验。使用两个系统，一个6传感器加速度计系统和一个8摄像机的三维运动捕捉系统运动被记录，以量化的时空，运动学和动力学参数。 与这两个系统中，参与者表现出增加步幅和双拥增减ED步态速度和节奏WP相比，NP（P &lt;0.05）。此外，动作捕捉，大单支持时间被发现WP（P &lt;0.05）。随着3-D采集，较小的臀部发电和力量的瞬间被发现在相对于NP，当超过评估脚跟接触和预摆以及较小的膝盖功率吸收在脚跟接触，预摆，和终端摆动WP周期（p &lt;0.05）。另外，可湿性粉剂在步态周期（P &lt;0.05）的立脚中间产生了在后跟的接触和与较大的时刻沿终端摇摆力小的时刻。被发现的姿势没有变化。 NW看起来适合中老年人促进正常的步态。三维运动捕捉应主要短持续时间的步态分析（ 即单步态周期）期间使用，而加速度计系统应在需要更长的持续时间的分析，如6MWT期间实例中主要使用。

时空步态参数当越野行走手杖行走，并评估使用运动捕捉和力板，步幅（P &lt;0.01），双拥时间（P &lt;0.001），而单支持时间（P &lt;0.001）进行比较，没有极走路都显著较长。另外，步态速度（P &lt;0.05）是显著较慢和韵律（P &lt;0.001）是具有极显著较小比不含老年人。此外，检查步态，当在一个较长时间的步行与6MWT和使用加速度...
