This study assessed whether the use of an "anchor system" benefited older adults who performed a tandem walking task. Additionally, we tested the effects of practice with the anchor system during walking on trunk stability, in the frontal plane, of older adults. Forty-four older adults were randomly assigned to three groups: control group, 0g anchor group, and 125g anchor group. Individuals in each group performed a tandem walking task on the GaitRite system with an accelerometer placed on the cervical region. The participants in the 125g anchor group held, in each hand, a flexible cable with a light mass attached at the end of the cable, which rested on the ground. While the participants walked, they pulled on the cables just enough to keep them taut as the masses slid over the ground. The 0g anchor group held an anchor tool without any mass attached to the end portion. The results of this study demonstrated that the use of the anchor system contributed to the reduction of trunk acceleration in the frontal plane. However, this effect did not persist after removal of the anchors, which suggests that the amount of practice with this tool was insufficient to generate any lasting effect, or that the task was not sufficiently challenging, or both.
本研究评估了使用“锚定系统”是否对执行串联步行任务的老年人有益。此外，我们还测试了在步行过程中使用锚定系统进行练习对老年人躯干在额状面稳定性的影响。44名老年人被随机分为三组：对照组、0克锚定组和125克锚定组。每组个体在GaitRite系统上执行串联步行任务，同时在颈部放置一个加速度计。125克锚定组的参与者每只手握住一根柔性电缆，电缆末端连接一个轻质物体，该物体放置在地面上。当参与者行走时，他们拉动电缆，使物体在地面上滑动的同时保持电缆绷紧。0克锚定组的参与者握住一个末端没有附加任何质量物体的锚定工具。本研究结果表明，使用锚定系统有助于降低额状面的躯干加速度。然而，移除锚定物后这种效果并未持续，这表明使用该工具的练习量不足以产生任何持久效果，或者该任务的挑战性不够，或者两者皆有。
