Abstract

Aim: To assess the adaptive response of older adults with a history of falls in a single Perturbation-Based Balance Training (PBT) session by examining the margin of stability (MoS) and the number of falls.

Methods: Thirty-two older adults with a history of falls underwent a treadmill walking session lasting 20-25 min. During the PBT protocol, participants experienced 24 unexpected perturbations delivered in two ways: acceleration or deceleration of the treadmill belt, with 12 perturbations in each direction. The MoS in the anteroposterior direction was assessed for the first and last perturbations of the session, during the perturbation step (N) and the recovery step (REC), along with the number of falls during the training session.

Results: There was no statistically significant difference in MoS between the first and last perturbations (acceleration and deceleration) for steps N and REC. Regarding the number of falls, a significant reduction was found when comparing the first half with the second half of the training session (p = .033). There were 13 falls in the first half and only three in the second half of the PBT session.

Conclusion: Older adults with a history of falls exhibited an adaptive response with a reduction in the number of falls during a single session of PBT despite not showing changes in the MoS.

基于扰动的平衡训练对有跌倒史的老年人适应性运动反应的影响

目的：通过研究稳定幅度（MoS）和跌倒次数，评估有跌倒史的老年人在一次惯性平衡训练（PBT）中的适应性反应：32名有跌倒史的老年人在跑步机上进行了20-25分钟的步行训练。在 PBT 方案中，参与者经历了 24 次意外扰动，扰动有两种方式：跑步机带加速或减速，每个方向各 12 次。在扰动步骤（N）和恢复步骤（REC）中，对训练过程中第一次和最后一次扰动的前后方向MoS以及训练过程中跌倒的次数进行了评估：在 N 步和 REC 步中，第一次和最后一次扰动（加速和减速）之间的 MoS 没有明显的统计学差异。在摔倒次数方面，训练前半段与后半段相比，摔倒次数明显减少（p = .033）。前半部分有 13 次跌倒，后半部分只有 3 次：结论：有跌倒史的老年人表现出了一种适应性反应，在单节 PBT 课程中跌倒次数减少，尽管 MoS 没有发生变化。

期刊介绍： Motor Control (MC), a peer-reviewed journal, provides a multidisciplinary examination of human movement across the lifespan. To keep you abreast of current developments in the field of motor control, it offers timely coverage of important topics, including issues related to motor disorders. This international journal publishes many types of research papers, from clinical experimental to modeling and theoretical studies. These papers come from such varied disciplines as biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. Motor Control, the official journal of the International Society of Motor Control, is designed to provide a multidisciplinary forum for the exchange of scientific information on the control of human movement across the lifespan, including issues related to motor disorders. Motor Control encourages submission of papers from a variety of disciplines including, but not limited to, biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. This peer-reviewed journal publishes a wide variety of types of research papers including clinical experimental, modeling, and theoretical studies. To be considered for publication, papers should clearly demonstrate a contribution to the understanding of control of movement. In addition to publishing research papers, Motor Control publishes review articles, quick communications, commentaries, target articles, and book reviews. When warranted, an entire issue may be devoted to a specific topic within the area of motor control.
