: To investigate how two types of body representation (body schema and body image) were affected in people with and without apraxia following a supratentorial stroke.: Observational cross-sectional study: Level 1 Specialist Neurological Rehabilitation Unit: 30 participants post-stroke diagnosed with (n = 10) and without apraxia (n = 20) according to a modified version of the short Ideomotor Apraxia Test.: Not applicable: Body schema assessed using the hand laterality recognition test and body part knowledge test; Implicit body image assessed using the sidedness test.: Left-sided lesions were more common in the apraxic group. Compared to people without apraxia post-stroke, those with apraxia showed significantly reduced accuracy and longer reaction times on the hand laterality test and fewer correct responses on the body part knowledge test. There was no between-groups difference in the sidedness test.: People with apraxia showed deficits in online body representations (body schema) that are used to plan and execute actions. Future research studies could target body schema deficits as an adjunct in the rehabilitation of apraxia.
: 探讨在大脑上矢状窦卒中后，有和无失用症的个体的两种身体表象（身体图式和身体意象）是如何受到影响的。
: 观察性横断面研究
: 1 级专家神经康复单位
: 30 名卒中后参与者，根据改良版 Ideomotor Apraxia Test 诊断为（n=10）和无失用症（n=20）
: 无
: 使用手偏向识别测试和身体部位知识测试评估身体图式；使用偏侧性测试评估内隐身体意象。
: 失用症组中左侧病变更为常见。与无卒中后失用症的个体相比，有失用症的个体在手偏向测试中的准确性明显降低，反应时间更长，在身体部位知识测试中的正确回答较少。偏侧性测试中无组间差异。
: 有失用症的个体表现出在线身体表象（身体图式）缺陷，这些缺陷用于计划和执行动作。未来的研究可以将身体图式缺陷作为失用症康复的辅助手段。
