行动不便的老年人需要使用滚动步行者来防止跌倒，但不正确的使用可能会导致事故。本研究的目的是调查疲劳对步态的影响，包括使用滚动助行器，老年人使用滚动助行器。在我们的方法中，使用由与滚动步行者的距离和步态速度建模。正常步态区域由这些数据的第5和第95百分位确定。每10 s的偏差率由数据超出正常步态区域的比率计算。三名老年滚动助行器使用者参与了我们的数据收集。他们从养老院的房间门口走到食堂（出站），再走回来（入站）。出站路线数据用于确定正常步态区域，入站路线数据用于分析。通过视频分析，记录16个异常行走行为，并与超过阈值0.2的偏差率进行比较。通过越轨率成功检测出与疲劳相关的5种行为和11种异常行为。它还检测到步态的8个细微变化。这些变化很难通过观察发现。检测和提醒这些变化可能对护理人员监督可能有跌倒风险的老年人有用。
Older adults with limited mobility are prescribed rolling walkers to prevent falls, but incorrect usage may cause accidents. The purpose of this study is to investigate the effects of fatigue on gait, including rolling walker usage, of older adult rolling walker users. In our approach, the usage is modelled by distance from rolling walker and gait velocity. The normal gait area is determined by the 5th and 95th percentile of these data. The deviance rate for every 10 s is calculated by the ratio of data exceeding the normal gait area. Three older adult rolling walker users participated our data collection. They walked from the entrance of their room in a nursing home to the canteen (outbound) and back (inbound). Outbound route data was used to determine area of normal gait while inbound route data for analysis. Through video analysis, 16 abnormal walking behaviors were noted and then compared to deviance rate that exceeded threshold value of 0.2. Five behaviors related to fatigue and another 11 abnormal behaviors were successfully detected by the deviance rate. It also detected eight slight changes in gait. These changes were difficult to detect through observation. Detecting and alerting these changes may be useful for caregivers to supervise older adults who may be at risk of falling.
