人的步行稳定性随年龄增长而变化,老年人步行稳定性降低。步行稳定性较差会导致老年人多次摔倒。本文采用近似熵这一非线性时间序列分析方法,对青年和老年受试者的步行稳定性进行了研究。本文的重点是使用一种可用于日常步行的便携式仪器来研究步行的稳定性。用近似熵技术分析了重心加速度的变异性,并以此作为评价青年和老年人步行稳定性的指标。利用所提出的方法,可以评估老年人的步行稳定性,并观察到老年人的步行稳定性在横向上下降。此外,还可以向老年受试者建议一个可以改善他们步行稳定性的步行速度。
Walking stability of human beings varies with age and reduces in the elderly people. Lesser walking stability causes many falls in the elderly people. In this paper, we have investigated the walking stability of young and elderly subjects using approximate entropy, a non-linear time series analysis method. Our emphasis in this paper is to investigate the walking stability using a portable instrumentation that can be used in the daily life walking. The variability of the acceleration of the centre of gravity is analysed by using approximate entropy technique and is used as an index to assess the walking stability of young and elderly people. By using the proposed method, it is possible to assess the walking stability of the elderly subjects and it is observed that the walking stability of elderly subjects decreases in the lateral direction. Moreover it is also possible to suggest a walking speed to the elderly subjects that can improve their walking stability.
