The hypothesis of the loss of complexity with aging and disease has received strong attention. Especially, the decrease of complexity of stride interval series in older people, during walking, was shown to correlate with falling propensity. However, recent experiments showed that a restoration of walking complexity in older people could occur through the prolonged experience of synchronized walking with a younger companion. This result was interpreted as the consequence of a complexity matching effect. The aim of the present study was to analyze the link between the restoration of walking complexity in older people and clinical measures usually used in the context of rehabilitation or follow-up of older people. We evidenced a link between restoring complexity, improving overall health and reducing fear of falling. In addition, we showed that 3 weeks of complexity matching training can have a positive effect on complexity up to 2 months post-protocol. Finally, we showed that the restoration of walking complexity obtained in the previous works is not guide-dependent.
随着衰老和疾病而出现复杂性丧失的假说受到了广泛关注。特别是，研究表明老年人在行走过程中步幅间隔序列复杂性的降低与跌倒倾向相关。然而，最近的实验表明，通过与年轻同伴同步行走的长期体验，老年人的行走复杂性可以得到恢复。这一结果被解释为复杂性匹配效应的结果。本研究的目的是分析老年人行走复杂性恢复与通常用于老年人康复或随访的临床指标之间的联系。我们证实了恢复复杂性、改善整体健康状况和减少跌倒恐惧之间存在联系。此外，我们还表明，为期3周的复杂性匹配训练在训练结束后长达2个月的时间里都能对复杂性产生积极影响。最后，我们表明，先前研究中获得的行走复杂性恢复并不依赖于引导。
