背景：帕金森病（PD）患者的步态障碍在同时执行另一项任务时加重。本研究探讨是否实践使PD的人走大的步骤，同时执行额外的任务，并确定如果训练PD的人走增加工作记忆任务导致改善步态时，步行和执行其他tasks simultaneous.Methods：步行模式记录前和后20分钟的双任务训练会议在20人PD。参与者在七种条件下进行了一系列10米步行试验：仅步态，以及六种不同的任务类型（例如，G.运动、认知）、领域（例如姿势、手动操作、语言、计算、听觉、视觉空间）和难度水平。双任务训练的目的是提高步长，同时进行各种语言和计数的工作记忆任务，是不同的那些使用在assessment.Results：以下培训，步长增加时，执行五个六个增加的任务，表明转移的双任务训练时，行走发生跨任务类型和域。步态速度的改善发生在六个增加的任务中的三个。当其他步态变量进行了检查，如步长的变化，很少改善与培训被发现。结论：训练可以导致更大的步骤时，在PD患者的双重任务条件下行走。在双任务训练过程中强调的步态变量似乎是一个重要的因素，使跨任务的训练改进的转移。(C)2009年爱思唯尔B。V.保留所有权利。
Background: Gait disorders in people with Parkinson's disease (PD) are accentuated when they perform another task simultaneously. This study examines whether practice enables people with PD to walk with large steps while performing added tasks, and to determine if training people with PD to walk with added working memory tasks leads to improvements in gait when walking and performing other tasks simultaneously.Methods: Walking patterns were recorded pre and post a 20 min dual task training session in 20 people with PD. Participants performed a series of 10 m walking trials under seven conditions: gait only, and with six different added tasks varying by task type (e. g. motor, cognitive), domain (e.g. postural, manual manipulation, language, calculation, auditory, visuospatial), and difficulty level. Dual task training aimed to improve step length while simultaneously undertaking a variety of language and counting working memory tasks that were different to those used in assessment.Results: Following training, step length increased when performing five of the six added tasks, indicating transfer of dual task training when walking occurred across task types and domains. Improvements in gait speed occurred in three of the six added tasks. When other gait variables were examined, such as step length variability, few improvements with training were found.Conclusions: Training can lead to larger steps when walking under dual task conditions in people with PD. The gait variable emphasised during dual task training appears to be an important factor in enabling the transfer of training improvements across tasks. (C) 2009 Elsevier B. V. All rights reserved.
