摘要目的：最近的证据表明，一些左脑损伤（LBD）患者难以使用熟悉的工具，因为无法推理物理对象的性质。一个基本问题是了解LBD患者在选择工具方面的剩余能力。方法：3名工具使用障碍的LBD患者、3名右脑损伤（RBD）患者和6名匹配的健康对照者进行了一项新的工具选择任务，包括从8个、4个或2个工具中选择相关工具从盒子中提取目标。三个标准被操纵，使相关和不相关的工具（尺寸，刚性，形状）。结果：与RBD患者和对照组相比，LBD患者选择的无关工具数量更多，解决任务的难度更大。所有参与者在基于刚度和形状选择相关工具时所犯的错误都大于基于尺寸的错误。在一些LBD患者中，即使在2-Choice条件下，困难仍然存在。结论：我们的研究结果证实，工具使用障碍是由于技术推理能力受损，导致患者在根据其物理特性选择工具时遇到困难。我们还进一步表明，这些困难可以随着选择的减少而减少，至少对于某些房产来说，这为康复计划开辟了新的途径。（黄金，2018,24,524-529）
Abstract Objectives: Recent evidence indicates that some left brain-damaged (LBD) patients have difficulties to use familiar tools because of the inability to reason about physical object properties. A fundamental issue is to understand the residual capacity of those LBD patients in tool selection. Methods: Three LBD patients with tool use disorders, three right brain-damaged (RBD) patients, and six matched healthy controls performed a novel tool selection task, consisting in extracting a target out from a box by selecting the relevant tool among eight, four, or two tools. Three criteria were manipulated to make relevant and irrelevant tools (size, rigidity, shape). Results: LBD patients selected a greater number of irrelevant tools and had more difficulties to solve the task compared to RBD patients and controls. All participants committed more errors for selecting relevant tools based on rigidity and shape than size. In some LBD patients, the difficulties persisted even in the 2-Choice condition. Conclusions: Our findings confirm that tool use disorders result from impaired technical reasoning, leading patients to meet difficulties in selecting tools based on their physical properties. We also go further by showing that these difficulties can decrease as the choice is reduced, at least for some properties, opening new avenues for rehabilitation programs. (JINS, 2018, 24, 524–529)
