背景：在中风发作时，口语单词产生的障碍是常见的。识别预测早期恢复的因素对于识别那些持续功能受损的风险更大的患者以及患者出院后的护理管理具有重要意义。目的：识别作为中风后口语产生能力急性恢复的预测因素的表现模式;识别早期和更慢性恢复之间的任何关联。方法和程序：急性中风患者在入院后1-2天内接受口头单词生产任务，并在7天内重复测试;一部分患者在三周到一年后进行了重复检测。性能进行了检查的错误率和类型，以确定潜在的预测因素的早期recovery.Outcome和结果：迂回的比例，并没有响应错误在初始测试与恢复的语言功能中风后的第一周内的幅度。发现患者的年龄和性别特征对观察到的早期恢复程度没有影响。没有检查的因素预测后期恢复。早期恢复的程度与后来recovery.Conclusions的程度不相关：目前的研究确定的任务表现，增加我们的理解如何口头文字生产恢复急性中风后的模式。早期恢复的程度并不能预测后期恢复的程度，这一发现与早期和晚期恢复是由于不同机制（急性中风中恢复的血流和后期恢复中的重组）的假设一致。
Background: Impairments in oral word production are common at the onset of stroke. The identification of factors that predict early recovery has important implications for identifying those at greater risk of continued impaired functioning, and the management of the patient's care following discharge.Aims: To identify patterns of performance that are predictors of acute recovery of oral word production abilities following stroke; to identify any association between early and more chronic recovery.Method and procedures: Acute stroke patients were administered oral word production tasks within 1-2 days of hospital admission, with repeat testing by 7 days;. a subset of patients had repeat testing between three weeks to one year later. Performance was examined for error rate and type to identify potential predictors of early recovery.Outcome and results: The proportion of circumlocution and no response errors at initial testing were associated with the magnitude of recovery of language functioning within the first week following stroke. Patient characteristics of age and gender were found to have no influence on the degree of early recovery observed. None of the examined factors predicted late recovery. The degree of early recovery was not associated with the degree of later recovery.Conclusions: The current study identified patterns of task performance that increase our understanding of how oral word production recovers following acute stroke. The finding that the degree of early recovery does not predict the degree of later recovery is consistent with the hypothesis that early and late recovery are due to different mechanisms (restored blood flow in acute stroke, and reorganization in later recovery).
