ABSTRACT The broad objective of this project is to determine whether standardized cognitive tests could be used in motor rehabilitation to better identify patients at risk for not responding to therapy. Older patients typically show smaller gains in motor rehabilitation than do younger patients, which may be due to cognitive impairments that interfere with their ability to relearn motor skills in therapy. Cognitive impairments have been shown to affect responsiveness to other types of rehabilitation. We therefore propose the use of standardized visuospatial tests for predicting responsiveness to upper extremity task-specific training in normal aging and after stroke. This motor skill learning paradigm uses household objects and mimics functional task-specific training, a motor rehabilitative approach that has been cited as superior to standard care for improving upper extremity skill post-stroke. Based on our preliminary work, we expect that older adults with better visuospatial scores will retain more motor skill one month after completing three sessions of task-specific training, compared to those with poorer visuospatial scores. Findings from this study will yield readily-available tools to help clinicians identify patients in upper extremity motor rehabilitation who are at risk for minimal treatment responsiveness. Findings will also determine which visuospatial tests have the most predictive value and should therefore be prioritized in screening when time or resources are limited. Further, if patients with lower visuospatial scores are more likely to show little to no improvement after a given motor rehabilitation protocol, then improving their visuospatial scores through cognitive rehabilitation could be a feasible, non-invasive strategy to maximize older patients’ motor rehabilitation responsiveness.

摘要 这个项目的主要目标是确定标准化的认知测试是否可以用于运动 康复，以更好地识别患者的风险，不响应治疗。老年患者通常表现为 运动康复的收益比年轻患者小，这可能是由于认知障碍， 干扰他们在治疗中重新学习运动技能的能力。认知障碍会影响 对其他类型康复的反应。因此，我们建议使用标准化的视觉空间 用于预测正常老化和中风后上肢任务特异性训练的反应性的测试。 这种运动技能学习范例使用家用物品，并模仿功能性任务特定训练，即运动技能训练。 一种康复方法，被认为在改善上肢技能方面优于标准护理上级 中风后根据我们的初步工作，我们预计具有更好视觉空间分数的老年人将 在完成三次特定任务训练后一个月， 他们的视觉空间分数更低这项研究的结果将产生现成的工具，以帮助临床医生 识别上肢运动康复中存在最小治疗反应风险的患者。 研究结果还将确定哪些视觉空间测试具有最大的预测价值，因此应该 在时间或资源有限的情况下优先进行筛选。此外，如果视觉空间评分较低的患者 在给定的运动康复方案后，更有可能表现出很少或没有改善，然后改善他们的 通过认知康复的视觉空间评分可能是一种可行的、非侵入性的策略， 患者的运动康复反应性。
