ABSTRACT

The therapy for unilateral spatial neglect (USN) is unclear. This case report investigated the effect of standing and walking training using a laser pointer based on stimulus-driven attention for USN. The patient was a right-handed 79-year-old man with cardiogenic cerebral embolism in the right middle and posterior cerebral arteries. Initially, we evaluated the absence of hemiparalysis in the lower limb and sensory disorder; almost all daily activities were performed independently. Intervention effects were verified using the BABA method. The course of the four phases (B1, A1, B2, A2) was conducted for 5 days. In the B1 and B2 phases, standing and walking training using a laser pointer was performed additionally to conventional physical therapy. Outcomes were measured using the Behavioural Inattention Test conventional subtest (BIT-c), Catherine Bergego Scale (CBS), and modified Posner task (MPT). The BIT-c remained unchanged in each phase. CBS scores improved after B1 and B2. In the MPT, the reaction time in the left space reduced after B1 and B2 compared with those in the A1 and A2 control phases. In this case, training may have contributed to the improvement in the response to the neglected space and behavioural assessment of USN.

摘要

单侧空间忽视 (USN) 的治疗尚不清楚。本案例报告调查了使用基于刺激驱动注意力的激光指示器对 USN 进行站立和行走训练的效果。患者是一位右利手的 79 岁男性，右大脑中动脉和后大脑动脉发生心源性脑栓塞。最初，我们评估了下肢偏瘫和感觉障碍的情况；几乎所有的日常活动都是独立进行的。采用BABA法验证干预效果。四个阶段（B1、A1、B2、A2）的课程进行了 5 天。在 B1 和 B2 阶段，除了常规物理治疗外，还进行了使用激光指示器的站立和行走训练。使用行为注意力不集中测试常规子测试 (BI​​T-c) 测量结果，Catherine Bergego 量表 (CBS) 和修改后的 Posner 任务 (MPT)。BIT-c 在每个阶段都保持不变。CBS 分数在 B1 和 B2 之后有所提高。在 MPT 中，与 A1 和 A2 控制阶段相比，B1 和 B2 后左侧空间的反应时间减少。在这种情况下，培训可能有助于改善对 USN 被忽视的空间和行为评估的反应。
