The analysis of stride series revealed a loss of complexity in older people, which correlated with the falling propensity. A recent experiment evidenced an increase of walking complexity in older participants when they walked in close synchrony with a younger companion. Moreover, a prolonged experience of such synchronized walking yielded a persistent restoration of complexity. This result, however, was obtained with a unique healthy partner, and it could be related to a particular partner’s behavior. The authors’ aim was to replicate this important finding using a different healthy partner and to compare the results to those previously obtained. The authors successfully replicated the previous results: synchronization yielded an attraction of participants’ complexity toward that of their partner and a restoration of complexity that persisted in two posttests, 2 and 6 weeks after the end of the training sessions. This study shows that this complexity restoration protocol can be applied successfully with another partner, and allows us to conclude that it can be generalized.

步幅系列的分析揭示了老年人复杂性的降低，这与跌倒倾向相关。最近的一项实验证明，当老年参与者与年轻同伴密切同步行走时，他们行走的复杂性会增加。此外，这种同步行走的长期体验产生了复杂性的持续恢复。然而，这个结果是在一个独特的健康伴侣身上获得的，它可能与特定伴侣的行为有关。作者的目的是使用不同的健康伴侣复制这一重要发现，并将结果与​​之前获得的结果进行比较。作者成功复制了之前的结果：同步产生了参与者的复杂性对他们的伴侣的吸引力，并在培训课程结束后的 2 周和 6 周的两个后测中持续了复杂性的恢复。这项研究表明，这种复杂性恢复协议可以与其他合作伙伴一起成功应用，并让我们得出结论，它可以推广。
