Clinicians and researchers recognize the need for measures offunctional status that possess linear properties and are reliable and valid. Rasch rating scale analysis provides the means for converting raw scores from functional assessment tools to linear measures for which measurement error can be quantified. The extent to which clinicians perceive patients who are undergoing rehabilitation after stroke as similarto other patient groups was investigated using the Functional Independence Measure (FIM). Earlier work demonstrated that the first 13 items of the FIM represent a measure of motor function and that the last 5 items represent a measu re of cognitive function. The FIM was used for patients with stroke in a manner similar to that for most other impairment groups on the motor items. Patients with stroke were, however, unlike many impairment groups in their ratings on the cognitive items. Tables showing raw score to scaled measure conversions are provided for two sets of impairment groups on the motor items and three sets of impairment groups on the cognitive items. Clinicians can be confident that the measures derived from the FIM are linear across the range of the instrument and are attuned to the uniqueness of patients with stroke and other specific impairments.
临床医生和研究人员认识到需要具备线性特性、可靠且有效的功能状态测量方法。拉施评分量表分析提供了将功能评估工具的原始分数转换为可量化测量误差的线性测量方法的手段。使用功能独立性测量(FIM)研究了临床医生将中风后正在接受康复治疗的患者视为与其他患者群体相似的程度。早期的研究表明,FIM的前13项代表运动功能测量,后5项代表认知功能测量。FIM用于中风患者的方式与用于大多数其他损伤组的运动项目的方式类似。然而,中风患者在认知项目评分上与许多损伤组不同。提供了运动项目两组损伤组和认知项目三组损伤组的原始分数到量表测量转换表。临床医生可以确信,从FIM得出的测量在整个仪器范围内是线性的,并且适合中风患者和其他特定损伤患者的独特性。
