Abstract

Background

Falls are a key cause of injury across all age groups. Perturbation-based training, particularly trip-induced perturbation, has shown promise in enhancing balance recovery in lab and real-world scenarios. This study aimed to synthesize the effects of trip-based perturbation training on fall risk, quantified by the fall rate, recovery step length, margin of stability, and maximum trunk flexion angle in healthy adults.

Methods

A literature search in major databases led to 11 qualified studies. Meta-analyses were conducted on the lab-induced fall rate, recovery step length, and maximum trunk flexion angle. Other outcome measures, such as fall rate in daily living conditions and margin of stability, were systematically reviewed to further assess the effects of trip-based perturbation training.

Findings

The pooled effect size was −0.30 (p < 0.001) for the lab-induced fall rate, 0.27 (p = 0.38) for the recovery step length, and − 9.81 (p = 0.20) for the maximum trunk flexion angle. The review also revealed that the training reduced all-cause prospective falls and improved the margin of stability after a trip.

Interpretation

Trip-based perturbation training significantly reduces the fall rate and enhances postural stability, as evidenced by improvements in the recovery step length, margin of stability, and trunk kinematics.

基于旅行的扰动训练降低跌倒风险效果的meta分析

背景：跌倒是所有年龄组受伤的主要原因。基于微扰的训练，特别是由绊倒引起的微扰，在实验室和现实世界中都显示出增强平衡恢复的希望。本研究旨在综合基于绊倒的扰动训练对跌倒风险的影响，通过跌倒率、恢复步长、稳定裕度和最大躯干屈曲角度对健康成人进行量化。方法对各大数据库进行文献检索，筛选出11篇符合要求的研究。对实验室诱发的跌倒率、恢复步长和最大躯干屈曲角度进行了meta分析。其他结果测量，如日常生活条件下的跌倒率和稳定裕度，被系统地审查，以进一步评估基于行程的扰动训练的效果。合并效应值为- 0.30 (p <；0.001), 0.27 （p = 0.38）为恢复步长，- 9.81 （p = 0.20）为躯干最大屈曲角度。该综述还显示，训练减少了所有原因的预期跌倒，并提高了旅行后的稳定性。基于行程的扰动训练可以显著降低跌倒率并增强姿势稳定性，这可以从恢复步长、稳定余量和躯干运动学的改善中得到证明。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
