Purpose: This study investigated the effect of movement speed on task accuracy and precision when participants were provided temporally oriented vibrotactile prompts. Materials and methods: Participants recreated a simple wrist flexion/extension movement at fast and slow speeds based on target patterns conveyed via vibrating motors affixed to the forearm. Each participant was given five performance-blinded trials to complete the task at each speed. Movement accuracy (root mean square error) and precision (standard deviation) were calculated for each trial in both the spatial and temporal domains. Results: 28 participants completed the study. Results showed temporal accuracy and precision improved with movement speed (both: fast > slow, p < 0.01), while all measures improved across trials (temporal accuracy and precision: trial 1 < all other trials, p < 0.05; spatial accuracy: trial 1 and 2 < all other trials, p < 0.05; spatial precision: trial 1 < all other trials, p < 0.05). Conclusions: Overall, temporal and spatial results indicate participants quickly recreated and maintained the desired pattern regardless of speed. Additionally, movement speed seems to influence movement accuracy and precision, particularly within the temporal domain. These results highlight the potential of vibrotactile prompts in rehabilitation paradigms aimed at motor re-education.

目的：本研究调查了当向参与者提供时间导向的振动触觉提示时，移动速度对任务准确性和精确度的影响。材料和方法：参与者根据通过固定在前臂上的振动电机传达的目标模式，以快速和慢速重新创建简单的手腕弯曲/伸展运动。每个参与者都接受了五次盲法试验，以在每种速度下完成任务。在空间和时间域中为每次试验计算运动精度（均方根误差）和精度（标准偏差）。结果： 28 名参与者完成了研究。结果显示时间准确度和精确度随着移动速度的提高而提高（两者：快 > 慢，p < 0.01），而所有测量都在试验中得到改善（时间精度和精度：试验 1 < 所有其他试验，p  < 0.05；空间精度：试验 1 和 2 < 所有其他试验，p  < 0.05；空间精度：试验 1 < 所有其他试验，p  < 0.05）。结论：总体而言，时间和空间结果表明，无论速度如何，参与者都能快速重建并保持所需的模式。此外，移动速度似乎会影响移动准确度和精确度，尤其是在时间域内。这些结果突出了振动触觉提示在旨在运动再教育的康复范例中的潜力。
