&NA;事实证明，增加手臂摆动或步长的口头指导可以改善帕金森病 (PD) 患者的整体步态模式。目前，我们的目的是确定这两种指令对于改善帕金森步态的相对功效。 6 名 PD 患者被随机分配到 2 个教学组中的 1 个：步长 (SL) 或摆臂 (AS)。两组都获得了有关先前试验和过渡信息（即改进下一次表现的指导方针）的录像带反馈。在训练前、训练中和训练后立即测量步态参数。为了确定改进是否能在较长时间内保持，训练后 1 周进行了保留测试。研究结果表明，两个教学组在训练期间的步态参数都有所改善，指导参数的变化更为明显。然而，SL 组的步态速度比 AS 组增加更多。尽管 SL 组在 1 周保留测试中保持了步态速度的这种改善，但受试者之间的效果并不一致。相反，受试者特征似乎会影响教学线索的有效性和步态变化的保留。这项试点研究的结果将有助于指导未来研究的主题选择。
&NA; Verbal instruction to increase either arm swing or step length has been shown to improve the overall gait pattern of individuals with Parkinson disease (PD). Presently, the aim was to determine the relative efficacy of these 2 instructions for improving Parkinsonian gait. Six individuals with PD were randomly assigned to 1 of 2 instructional groups: step length (SL) or arm swing (AS). Both groups were given videotape feedback about the prior trial and transitional information (ie, guidelines to improve the next performance). Gait parameters were measured prior to, during, and immediately after training. To determine if improvements were maintained over an extended period of time, a retention test was administered 1 week after training. Findings indicated that both instructional groups improved on gait parameters during training, with more marked change evident for the instructed parameter. Gait velocity, however, increased more for the SL than the AS group. Although the SL group maintained this improvement in gait velocity on the 1‐week retention test, the effects were not consistent across subjects. Rather, subject characteristics seemed to affect the efficacy of instructional cues and the retention of gait changes. The findings from this pilot study will be useful in guiding subject selection in future research.
