背景由于运动启动和执行困难，帕金森病（PD）患者通常被鼓励有意识地监测和控制其动作的力学。这被描述为“再投资”，并已被证明有助于调解有效的运动输出。奇怪的是，在PD患者特别有动力有效移动的情况下，再投资可能会加剧现有的移动赤字。objective.研究PD患者样本的再投资倾向。方法. 55名PD患者的志愿者样本被要求完成先前验证的测量，再投资量表。一个子样本（和年龄匹配的控制）被要求完成一个最近开发的，运动特定的，版本的规模。数据收集采用简易精神状态检查和Hoehn & Yahr量表。参与者的人口统计资料，包括发病年龄和疾病持续时间，也进行了整理。结果多元回归分析表明，疾病的持续时间与再投资规模和运动具体再投资规模的再投资得分。结论.随着时间的推移，参与者似乎越来越意识到他们行动的机制。可能的解释，这一发现进行了讨论，参考康复。
Background. As a consequence of difficulties in movement initiation and execution, people with Parkinson's disease (PD) are typically encouraged to consciously monitor and control the mechanics of their actions. This is described as 'reinvestment' and has been shown to help mediate effective motor output. Paradoxically, in situations where people with PD are particularly motivated to move effectively, reinvestment may exacerbate existing movement deficits. Objective. To examine the propensity for reinvestment in a sample of people with PD. Methods. A volunteer sample of 55 people with PD was asked to complete a previously validated measure, the Reinvestment Scale. A sub-sample (and age matched controls) was asked to complete a recently developed, movement specific, version of the Scale. Data was collected on Mini Mental State Examination and the Hoehn & Yahr Scale. Participant demographics, including age of onset and duration of disease, were also collated. Results. Multiple regression analyses showed that duration of disease was associated with reinvestment score on both the Reinvestment Scale and the Movement Specific Reinvestment Scale. Conclusions. Participants appeared to become more aware of the mechanics of their actions over time. Possible explanations for this finding are discussed with reference to rehabilitation.
