本研究旨在探讨脑卒中对视觉和言语刺激记忆过程（编码、存储和检索）的影响及其对运动训练的启示。研究对象为12例（右脑病变6例，左脑病变6例，病变后6-36个月）和12例健康者，年龄45-65岁，男女均可。在测试过程中评估编码和存储过程，每个受试者有三次尝试识别两个列表，每个列表有10个刺激（10个数字和10个涉及动物和物体的单词）。通过即时自由检索和识别测试来评价检索过程。数据分析采用Mann-Whitney检验。患者的表现较差（编码-视觉：p = 0.0001和语言：p = 0.0001；存储-语言：p = 0.0001），右侧病变患者的视觉编码表现较差（p = 0.0005），左侧病变患者的语言存储（p = 0.0246）和检索表现较差（p = 0.0001）。结果表明，患者不能充分编码和存储这些信息，但他们有足够的能力通过识别来恢复，这意味着在脑血管疾病患者的治疗中有必要进行观察性、分布式和多样化的实践。
This study intended to evaluate the influence of stroke on memory processes (encoding, storage and retrieval) of visual and verbal stimuli and its implications to the motor practice. Twelve patients (6 with right and 6 with left brain lesions; 6-36 months post-lesion) and 12 healthy subjects, 45-65 years old from both sexes were studied. The encoding and storage processes were evaluated during test sessions where each subject had three attempts to identify two lists with 10 stimuli each (10 figures and 10 words referring to animals and objects). The retrieval process was evaluated by immediate free retrieval and by recognition tests. Data were analyzed by Mann-Whitney test. Performance was worse in patients (encoding-visual: p = 0.0001 and verbal: p = 0.0001; storage-verbal: p = 0.0001) and those with right lesions had worse performance in visual encoding (p = 0.0005) and those with left lesions had in verbal storage (p = 0.0246) and retrieval (p = 0.0001). According to results it is suggested that the patients were not able to adequately codify and store the information, however, they were adequately able to recover by recognition and this implicates the necessity to make a observational, distributed and varied practice in cerebrovascular disease patients therapy.
