Preventing falls is important in the elderly. One reason for falling is tripping or stumbling; hence, it is important to improve the crossing motion. This study aimed to compare speed- and accuracy-oriented crossing training and establish a useful training method. To investigate the effects of crossing motion training, we conducted a randomized controlled trial. Twenty healthy elderly individuals (aged 71.7 ± 1.5 years) were randomly assigned to two groups: speed training and accuracy training groups. They practiced initiating their crossing motion faster or more accurately for 12 weeks. Using a three-dimensional motion analysis system, the data on the crossing motion was captured before and after the training period. We set four conditions (normal speed, fast, leaning stance, and leaning stance and fast) and two directions (anterior and lateral) to analyze the crossing motion. The crossing motion of the speed training group became significantly faster compared to baseline (p < 0.05); however, the accuracy of the crossing motion of the accuracy training group was not statistically significant. Speed training in this study had clear effects on crossing motion. It is surprising that crossing motion training from a normal upright stance can also improve swing speed from the leaning stance. We believe that this training is easy and useful in the elderly population.
预防老年人跌倒很重要。跌倒的一个原因是绊倒或踉跄；因此，改善跨越动作很重要。本研究旨在比较速度和准确性导向的跨越训练，并建立一种有用的训练方法。为了研究跨越运动训练的效果，我们进行了一项随机对照试验。20 名健康的老年人（年龄 71.7 ± 1.5 岁）被随机分为两组：速度训练组和准确性训练组。他们进行了 12 周的更快或更准确地开始跨越动作的练习。使用三维运动分析系统，在训练前后捕获跨越运动的数据。我们设置了四个条件（正常速度、快速、倾斜姿势和倾斜姿势加快速）和两个方向（前后）来分析跨越运动。与基线相比，速度训练组的跨越动作明显变快（p < 0.05）；然而，准确性训练组的跨越动作准确性没有统计学意义。本研究中的速度训练对跨越运动有明显的效果。令人惊讶的是，来自正常直立姿势的跨越运动训练也可以提高倾斜姿势的摆动速度。我们相信这种训练在老年人中既简单又实用。
