跑步机为研究帕金森氏病(PD)患者的步态提供了一种安全和方便的方法，但从跑步机步态得出的结果可能不同于地面步行。目的：研究帕金森病患者和健康对照组在地面步行和跑步机步行之间步态指标和步行速度之间的关系。我们比较了29名健康对照和27名非用药状态的帕金森病患者。受试者首先在仪表化步道上行走，然后以地面步行速度的85%、100%和115%在仪表化跑步机上行走。计算了每个受试者在地面行走和跑步机行走时的平均步长和步频。地面步行和跑步机步行的步长和节奏都不同。在PD组和对照组中，步长和步频对步速的回归显示出地面步态和跑步机步态的对数-对数关系。对于跑步机步态，地面步态中PD和对照组之间的差异保持不变，不仅在跑步机速度与地面速度匹配时，而且在跑步机速度与地面速度相差±15%的情况下。这些结果表明，与地面步行相比，跑步机上PD对步长和节奏的影响及其与步速的关系被保留下来。我们得出结论，跑步机方案适合在实验室用于帕金森病步态疗法的研究。
Treadmills provide a safe and convenient way to study the gait of people with Parkinson’s disease (PD), but outcome measures derived from treadmill gait may differ from overground walking. To investigate how the relationships between gait metrics and walking speed vary between overground and treadmill walking in people with PD and healthy controls. We compared 29 healthy controls to 27 people with PD in the OFF-medication state. Subjects first walked overground on an instrumented gait walkway, then on an instrumented treadmill at 85, 100 and 115% of their overground walking speed. Average stride length and cadence were computed for each subject in both overground and treadmill walking. Stride length and cadence both differed between overground and treadmill walking. Regressions of stride length and cadence on gait speed showed a log-log relationship for both overground and treadmill gait in both PD and control groups. The difference between the PD and control groups during overground gait was maintained for treadmill gait, not only when treadmill speed matched overground speed, but also with ±15% variation in treadmill speed from that value. These results show that the impact of PD on stride length and cadence and their relationship to gait speed is preserved in treadmill as compared to overground walking. We conclude that a treadmill protocol is suitable for laboratory use in studies of PD gait therapeutics.
