摘要
衰老通常会导致老年人步态特征为速度变慢、步幅变短和周期增加;改善步态可以显著提高生活质量。早期的步态训练有助于减少日后的步态障碍。增强现实(AR)技术在步态训练中大有可为,它能提供实时反馈和指导练习,以改善行走模式和步态参数。本研究的目的是观察同步行走化身提供的渐进空间和时间线索对老年参与者步态的影响。这项实验有 19 名 70 岁以上的参与者参加,他们一边行走一边与提供视听空间和时间提示的同步行走化身互动。空间提示和时间提示分别通过距离变化和相位差变化提供。WalkMate AR 系统用于使虚拟人的行走周期与参与者的行走周期同步,并提供与脚部接触相匹配的听觉提示。这项研究评估了距离和相位差变化对步幅、周期时间和步速的直接影响和延续影响。结果表明,渐进的空间和时间提示会显著影响老年人的步态参数,在步态康复和训练中具有潜在的应用价值。
Effects of Gradual Spatial and Temporal Cues Provided by Synchronized Walking Avatar on Elderly Gait
Aging often leads to elderly gait characterized by slower speeds, shorter strides, and increased cycle; improving gait can significantly enhance the quality of life. Early gait training can help reduce gait impairment later on. Augmented reality (AR) technologies have shown promise in gait training, providing real-time feedback and guided exercises to improve walking patterns and gait parameters. The aim of this study was to observe the effects of gradual spatial and temporal cues provided by a synchronized walking avatar on the gait of elderly participants. This experiment involved 19 participants aged over 70 years, who walked while interacting with a synchronized walking avatar that provided audiovisual spatial and temporal cues. Spatial cueing and temporal cueing were provided through distance changes and phase difference changes, respectively. The WalkMate AR system was used to synchronize the avatar’s walking cycle with the participants’, delivering auditory cues matched to foot contacts. This study assessed the immediate and carry-over effects of changes in distance and phase difference on stride length, cycle time, and gait speed. The results indicate that gradual spatial and temporal cueing significantly influences elderly gait parameters, with potential applications in gait rehabilitation and training.
