为了区分功能障碍步态，临床医生需要测量每个人群的参考步态参数。这项研究为1,400多名65岁以上的健全成年人提供了广泛使用的参数的标准值。我们还测量了脚部间隙参数（即，在摆动阶段期间脚离地面的高度），这对于理解步态和福尔斯之间的复杂关系以及障碍物克服策略是至关重要的。我们在每只脚上使用了一个穿鞋的惯性传感器和先前验证的算法来提取步态参数，在20米的步行试验中，在走廊中以自选的步伐。我们通过考虑年龄和身高因素的影响，研究了男性和女性参与者之间步态参数的差异。此外，我们研究了间隙参数与步态速度的相互关系。本研究提供的步态参数的样本量和广度为研究人员提供了独特的参考资源。
In order to distinguish dysfunctional gait, clinicians require a measure of reference gait parameters for each population. This study provided normative values for widely used parameters in more than 1,400 able-bodied adults over the age of 65. We also measured the foot clearance parameters (i.e., height of the foot above ground during swing phase) that are crucial to understand the complex relationship between gait and falls as well as obstacle negotiation strategies. We used a shoe-worn inertial sensor on each foot and previously validated algorithms to extract the gait parameters during 20 m walking trials in a corridor at a self-selected pace. We investigated the difference of the gait parameters between male and female participants by considering the effect of age and height factors. Besides; we examined the inter-relation of the clearance parameters with the gait speed. The sample size and breadth of gait parameters provided in this study offer a unique reference resource for the researchers.
