Abstract

ABSTRACTThe effects of footedness and aging on postural maintenance function were examined in this study. Using the postural maintenance task, the trajectories of the centre of pressure (COP) were measured with a stabilometer in the lateral and posterior/anterior directions. One hundred and ninety-three right-footers (112 middle-aged: 40-64 years old and 81 old-aged: 65-80 years old) and thirty-two left-footers (14 middle-aged and 18 old-aged) among healthy community members participated in this study. Using the ratio of the COP deviation area sizes for the open- vs. closed-eye conditions as an index, the ratios in the lateral and the posterior/anterior directions were compared in relation to the footedness and the age groups. The results indicated that the left-footers of the older adults group showed a larger COP deviation ratio than that of the middle-aged group, and the left-footers showed a larger deviation ratio in the lateral direction than in the posterior-anterior direction. These findings suggest a weak postural maintenance function of the older adults left footers. As most left-footers are left-handed, health promotion staff should notice that older adults who are left-handers are at a higher risk of falling.

足行性和年龄在姿势控制上的关系:来自Yakumo研究的证据。

摘要本研究探讨足性和年龄对体位维持功能的影响。使用姿势维持任务，用稳定计测量压力中心(COP)在外侧和后/前方向的轨迹。在健康的社区成员中，193名右足者(中年40-64岁112名，老年65-80岁81名)和32名左足者(中年14名，老年18名)参与了本研究。以睁眼与闭眼状态下COP偏差面积的比值为指标，比较侧面和前后方向的比值与足性和年龄组的关系。结果表明:老年人组左脚的COP偏差比中年人组大，且左脚在外侧方向上的偏差比在后前方向上的偏差大。这些发现表明，老年人左脚的姿势维持功能较弱。由于大多数左撇子都是左撇子，健康促进人员应该注意到，左撇子的老年人摔倒的风险更高。

期刊介绍： Laterality: Asymmetries of Body, Brain and Cognition publishes high quality research on all aspects of lateralisation in humans and non-human species. Laterality"s principal interest is in the psychological, behavioural and neurological correlates of lateralisation. The editors will also consider accessible papers from any discipline which can illuminate the general problems of the evolution of biological and neural asymmetry, papers on the cultural, linguistic, artistic and social consequences of lateral asymmetry, and papers on its historical origins and development. The interests of workers in laterality are typically broad.
