[Purpose] The purpose of this study was to identify the optimal visual cues for gait disturbance in patients with Parkinson's disease based on the luminous duration and the individual patient preferences for a wearable visual cue device. [Participants and Methods] Twenty-four patients with Parkinson's disease walked while wearing only a visual cue device in the control condition. They then walked while the device was set to two stimulus conditions: the luminous duration at 10% and 50% of the individual gait cycle. After walking under the two stimulus conditions, the patients were asked for their preferred visual cue condition. The walking results were compared between the two stimulus conditions and the control condition. Gait parameters were compared among the three conditions. The comparisons with preference, non-preference, and control conditions were also made for the same gait parameter. [Results] When compared to the control condition, walking with visual cues in the stimulus conditions reduced stride duration and increased cadence. The preference and non-preference conditions had shorter stride durations than the control condition. Furthermore, the preference condition also resulted in a faster gait speed than the non-preference condition. [Conclusion] This study suggests that a wearable visual cue device with the patient's preferred luminous duration may help manage gait disturbance in patients with Parkinson's disease.
[目的] 本研究旨在基于发光持续时间以及患者对可穿戴视觉提示装置的个人偏好，确定帕金森病患者步态障碍的最佳视觉提示。[参与者与方法] 24名帕金森病患者在对照条件下仅佩戴视觉提示装置行走。然后，在将装置设置为两种刺激条件时行走：发光持续时间为个体步态周期的10%和50%。在两种刺激条件下行走后，询问患者他们偏好的视觉提示条件。比较两种刺激条件与对照条件下的行走结果。比较三种条件下的步态参数。还对相同的步态参数进行了偏好、非偏好和对照条件的比较。[结果] 与对照条件相比，在刺激条件下使用视觉提示行走可缩短步幅持续时间并提高步频。偏好和非偏好条件下的步幅持续时间均短于对照条件。此外，偏好条件下的步态速度也比非偏好条件快。[结论] 本研究表明，具有患者偏好发光持续时间的可穿戴视觉提示装置可能有助于管理帕金森病患者的步态障碍。
