This controlled study examined the effects of a gait prioritization strategy on walking in people with Parkinson's disease (PD). Participants in the training group (n=6) received 30-min therapy to prioritize their attention to take big steps while performing serial three subtractions. Participants in the control group (n=6) received no therapy. Stride length, gait velocity, and accurate enumeration rate were measured at baseline, immediately after training and 30 min after training under both single-task (walk only or subtract only) and dual-task (walk and subtract) conditions. Performance was also assessed during therapy for the training group. Stride length and gait velocity increased immediately when participants followed instructions to prioritize their attention to take big steps (p=.005, p=.04). Further, the gait variables increased for both single and dual-task conditions for at least 30 min after training when compared to the controls; with a simultaneous reduction in the magnitude of dual-task interference (p=.03, p=.03). No difference in the accurate enumeration rate was found at any of the assessment time points. Therefore, prioritizing attention to take big steps can be an effective strategy to increase the stride length and walking speed in some people with PD.
本对照研究旨在探讨步态优先化策略对帕金森病（PD）患者行走的影响。训练组（n=6）参与者接受 30 分钟的治疗，以优先注意迈大步进行连续三项减数运算。对照组（n=6）参与者不接受治疗。在基线、训练后即刻和训练后 30 分钟，在单任务（仅行走或仅减数）和双任务（行走和减数）条件下，测量步长、步态速度和准确计数率。还在训练组治疗期间评估了表现。当参与者按照优先注意迈大步的指示时，步长和步态速度立即增加（p=.005，p=.04）。此外，与对照组相比，在训练后至少 30 分钟内，单任务和双任务条件下的步态变量均增加，同时双任务干扰的幅度减小（p=.03，p=.03）。在任何评估时间点均未发现准确计数率的差异。因此，优先注意迈大步可能是增加某些 PD 患者步长和行走速度的有效策略。
