背景：步态动力学和步态可变性等步行不稳定性的测量方法已被证明可以在步态受限或活动障碍的老年人群中识别未来的跌倒者。这项研究调查了一组健康和活跃的老年女性，步行不稳定性的测量是否可以预测未来12个月的跌倒。方法：97名年龄在55岁到90岁之间的健康活跃女性绕着一个连续的步行回路步行7分钟。由GAITRite(注册商标)步行道和脚上安装的加速计记录的步态数据被用来计算步幅动力学和步态可变性的测量。对参与者的身体功能和平衡能力进行了评估。结果：肢体间差异有统计学意义(P<0.05)。
Background: Measures of walking instability such as stride dynamics and gait variability have been shown to identify future fallers in older adult populations with gait limitations or mobility disorders. This study investigated whether measures of walking instability can predict future fallers (over a prospective 12 month period) in a group of healthy and active older women.Methods: Ninety-seven healthy active women aged between 55 and 90 years walked for 7 min around a continuous walking circuit. Gait data recorded by a GAITRite (R) walkway and foot-mounted accelerometers were used to calculate measures of stride dynamics and gait variability. The participant's physical function and balance were assessed. Fall incidence was monitored over the following 12 months.Results: Inter-limb differences (p
