在身临其境的 VR 环境中, 我们详细介绍了一种运动捕捉系统的日常生活运动测量协议。首先, 实验设置指导如何设置, 准备, 并使参与者熟悉身临其境的虚拟现实环境。其次, 我们在 VR 中开发了两个标准化的 IADL 任务。第三, 步骤3和步骤5在协议部分是最关键的步骤, 以尽量减少 VR 疾病。在虚拟环境中设置运动捕获系统 (步骤 3) 时, 很重要的一点是, 将跟踪摄像机安装到足够高的高度, 以便完全覆盖捕...

日常生活的工具活动 (IADL), 例如处理金融交易, 使用公共交通和烹调, 是医学标记, 因为他们需要多重神经心理学功能1。因此, IADL 能力受损被认为是神经疾病的前体, 如轻度认知障碍 (MCI) 和痴呆症2。黄金对 IADL 任务的全面审查3表示, 更具认知性要求的任务, 例如管理财务和使用公共交通, 是 MCI 和痴呆症的最早预测因素。
迄今为止, 最常用的 IADL 评估是自报告的调查表、基于线人的调查表和基于性能的评估4。基于问卷的 IADL 评估方法具有成本效益和易用性, 但容易引起主观偏见。例如, 当自我报告时, 患者倾向于过度或低估他们的 IADL 能力5。同样, 由于观察者的误解或知识缺口4, 举报人误判 IADL 能力。因此, 要求患者执行特定 IADL 任务的基于绩效的评估是可取的, 尽管许多任务不适用于一般临床设置6。
最近, 虚拟现实 (VR) 研究表明, 这项技术可以在医学和医疗领域有重要的应用, 其中包括从训练到康复到医疗评估的所有内容7。所有参与者都可以在相同的 VR 条件下进行测试, 这会模仿真实世界。例如, Allain et 。8开发了一个虚拟的咖啡制作任务, 并表明有认知障碍的患者执行的任务很差。科林格et 。9为邮件和购物任务开发了另一个虚拟现实环境, 并发现 vr 中任务完成时间与神经心理测试结果之间有意义的关系。以前的 VR 研究 IADL 评估主要集中在简单的性能指标, 如反应时间或准确性时, 使用传统的输入设备, 如鼠标和键盘8,9。因此, 需要更详细的 IADL 性能数据, 以便有效地筛选 MCI4的患者。
实时运动捕获数据的运动学分析是定量记录与 IADL 任务相关的详细性能数据的有力方法。例如, 白色et 。10开发了一个虚拟厨房, 它在日常生活任务期间捕获参与者的联合角度数据, 并使用捕获的数据定量地评估物理治疗的有效性。Dimbwadyo-Terrer et11开发了一个身临其境的 VR 环境来评估在进行基本日常生活任务时上肢的表现, 并表明在 vr 环境中记录的运动学数据与上肢功能尺度高度相关。这些运动学分析与运动捕捉系统可以提供进一步的机会, 以快速评估患者的认知障碍12。将详细的运动学数据纳入 MCI 患者的筛查, 大大改善了与健康对照组比较的患者的分类13。
在这里, 我们描述了一个协议, 以评估在身临其境的 VR 环境中的运动捕捉系统的日常生活运动的运动学。该协议包括两个复杂的 IADL 任务: "任务 1: 取款" (处理金融交易) 和 "任务 2: 乘坐公交车" (使用公共交通)。在完成任务的同时, 一个运动捕捉系统跟踪了支配手和头部的位置和方向。完成任务1后, 收集了主手轨迹、移动距离和完成时间。在任务2中, 收集了头部轨迹、移动距离和完成时间。本文的 "代表性结果" 部分详细介绍了 MCI 患者 (即、IADL 功能受损) 与健康控制 (即、IADL 功能完好) 的初步测试。

measuring the kinematics of daily living movements with motion capture systems in virtual reality

无法完成日常生活中的工具性活动 (IADL) 是各种神经心理疾病的前兆。基于问卷的 IADL 评估很容易使用, 但容易引起主观偏见。在这里, 我们描述了一个新的虚拟现实 (VR) 测试, 以评估两个复杂的 IADL 任务: 处理金融交易和使用公共交通。当参与者在 VR 设置中执行任务时, 运动捕获系统会跟踪占主导地位的手和头部在三维笛卡尔坐标系中的位置和方向。运动学原始数据被收集和转换成 ' 运动性能测量, '即, 运动轨迹, 移动距离和完成时间。运动轨迹是空间中特定身体部分 (例如、主导的手或头) 的路径。移动距离指的是轨迹的总距离, 完成 IADL 任务所花费的时间。这些运动措施可能会歧视患者的认知障碍, 从健康的控制。这个运动测量协议的发展允许检测早期 IADL 相关的认知障碍。

用统计软件 R 分析了 "任务 1: 提取资金" 的 CSV 文件, 计算了主手轨迹、移动距离和完成时间。主导手运动的轨迹是可视化的 (图 6)。占主导地位的手的移动距离是通过在执行任务1的同时总结出顺序手位置之间的总距离来计算的。位置之间的距离是欧式距离。完成时间意味着完成整个任务所花费的时间 (即, 从步骤 1 "将卡插入 atm" 到步骤 8 "从 atm...
