随着年龄的增长，体位稳定性下降，威胁到老年人的健康和生活质量。单腿站立（OLS）是一种标准且常用的姿势稳定性评估方法，OLS中的姿势摇摆已被证明与年龄有关。体位摇摆在身体各节段之间的传播可能暗示了平衡控制的潜在机制。然而，它还没有被完全理解。因此，本文的目的是研究健康老年人头部、躯干和下肢的角摆动及其传播。对标准化的角速度进行了相互关联，并对68名老年人进行了实验。结果表明，头、髋、踝关节对角度摇摆传递的影响相关性较低，潜伏期较长。
Postural stability degrades with age, threating the health and life quality of the older adults. One Leg Stance (OLS) is one of the standard and commonly adopted assessments for postural stability, and the postural sway in OLS has been demonstrated to be related with age. The propagation of postural sway between body segments could be a hint to the underlying mechanism of balance control. However, it is not yet fully understood. Therefore, the aim of this paper was to study the angular sways and their propagation of the head, trunk, and lower limb in healthy older adults. A cross-correlation of the normalized angular speeds was performed and the experiment with 68 older adults was conducted. The results showed that the head, hip and ankle joints affected the transfer of angular sway with a relatively lower correlation and longer latency.
