Falls are a recognized risk factor for unintentional injuries among older adults, accounting for a large proportion of fractures, emergency department visits, and urgent hospitalizations. Human balance and gait research traditionally uses linear or qualitative tests to assess and describe human motion; however, human motion is neither a simple nor a linear process. The objective of this research is to identify and to learn more about what factors affect balance using nonlinear dynamical techniques, such as basin boundaries. Human balance data was collected using dual force plates for leans using only ankle movements as well as for unrestricted leans. Algorithms to describe the basin boundary were created and compared based on how well each method encloses the experimental data points as well as captures the differences between the two leaning conditions.

吸引人类平衡的盆地。

跌倒是公认的老年人意外伤害的危险因素，占骨折，急诊就诊和紧急住院的很大一部分。传统上，人体平衡和步态研究使用线性或定性测试来评估和描述人体运动。但是，人体运动既不是简单的过程也不是线性的过程。这项研究的目的是使用非线性动力学技术（例如盆地边界）来识别并了解哪些因素会影响平衡。使用双力板收集人体平衡数据，仅通过脚踝运动以及无限制的倾斜来获得倾斜。
