Abstract

BACKGROUND

Impaired gait adaptability is one of the major causes of falls among older adults owing to inappropriate gait adjustments in cluttered environments. Training programs designed to improve gait adaptability behavior in a systemic approach may prevent falls in older adults. Recently, virtual reality (VR) technology has been prominent as a relevant gait training tool because of its training implementation potential.

OBJECTIVE

This study was designed to compare the effectiveness of a VR-based gait training program (VR group) for improving gait adaptability behavior and, thus, reducing the risk of falls relative to a conventional training program such as Nordic walking (NW; NW group). We hypothesized that the VR-based gait training program will lead to greater gait adaptability improvements.

METHODS

We will be conducting a randomized controlled trial with pretests, posttests, retention tests, and follow-up. In total, 40 healthy independent-living community dwellers (aged between 65 and 80 years) will be allocated, after a general medical examination, to the VR or the NW group for a training program of 6 weeks. Primary outcomes related to gait adaptability capacities (ie, analysis of adjustments made in different locomotor tasks) and acceptance of the VR device (ie, analysis of acceptance) will be assessed before and after the intervention and 1 month after the completion of the training program (retention). A follow-up will be done during the 12 months after the completion of the gait training program.

RESULTS

Data collection will begin in September 2025, and the first results are expected in December 2025.

CONCLUSIONS

The findings of this study may demonstrate the relative relevance of a gait training program in VR versus a conventional one for improving gait adaptability behavior in healthy older adults and, thus, prevent the chances of a fall.

摘要

背景

步态适应性受损是老年人跌倒的主要原因之一，这是由于在杂乱环境中步态调整不当所致。以系统方式设计的旨在改善步态适应性行为的训练计划可能会预防老年人跌倒。最近，虚拟现实（VR）技术因其训练实施潜力而成为一种重要的步态训练工具。

目的

本研究旨在比较基于VR的步态训练计划（VR组）在改善步态适应性行为方面的有效性，从而相对于诸如越野行走（NW；NW组）等传统训练计划降低跌倒风险。我们假设基于VR的步态训练计划将带来更大的步态适应性改善。

方法

我们将进行一项包含预测试、后测试、保留测试和随访的随机对照试验。总共40名健康的独立生活社区居民（年龄在65至80岁之间）在进行全面体检后，将被分配到VR组或NW组，进行为期6周的训练计划。在干预前后以及训练计划完成后1个月（保留期），将评估与步态适应能力相关的主要结局（即分析在不同运动任务中所做的调整）以及VR设备的接受度（即接受度分析）。在步态训练计划完成后的12个月内将进行随访。
