External cues improve walking by evoking internal rhythm formation related to gait in the brain in patients with Parkinson's disease (PD). This study examined the usefulness of using a portable gait rhythmogram (PGR) in music therapy on PD-related gait disturbance. A total of 19 subjects with PD who exhibited gait disturbance were evaluated for gait speed and step length during a 10 m straight walking task. Moreover, acceleration, cadence, and trajectory of the center of the body were estimated using a PGR. Walking tasks were created while incorporating music intervention that gradually increased in tempo from 90 to 120 beats per minute (BPM). We then evaluated whether immediate improvement in gait could be recognized even without music after walking tasks by comparing pre- (pre-MT) and post-music therapy (post-MT) values. Post-MT gait showed significant improvement in acceleration, gait speed, cadence, and step length. During transitions throughout the walking tasks, acceleration, gait speed, cadence, and step length gradually increased in tasks with music. With regard to the trajectory of the center of the body, we recognized a reduction in post-MT medio-lateral amplitude. Music therapy immediately improved gait disturbance in patients with PD, and the effectiveness was objectively shown using PGR.
外部提示通过在大脑中唤起与步态相关的内部节律形成来改善帕金森病（PD）患者的步行。本研究探讨了在 PD 相关步态障碍的音乐治疗中使用便携式步态节奏图（PGR）的有用性。评估了 19 名表现出步态障碍的 PD 患者在 10 米直线行走任务中的步态速度和步长。此外，还使用 PGR 估计了身体中心的加速度、步频和轨迹。行走任务是在音乐干预的情况下创建的，音乐干预的节奏从 90 拍/分钟（BPM）逐渐增加到 120 BPM。然后，我们通过比较音乐治疗前（预-MT）和音乐治疗后（后-MT）的值，评估在行走任务后即使没有音乐是否可以立即识别到步态的改善。后-MT 步态在加速度、步态速度、步频和步长方面均有显著改善。在行走任务的整个过渡过程中，加速度、步态速度、步频和步长在有音乐的任务中逐渐增加。关于身体中心的轨迹，我们注意到后-MT 横向幅度减小。音乐治疗立即改善了 PD 患者的步态障碍，并且使用 PGR 客观地显示了其有效性。
