采用Fugl-Meyer上肢聚类分析（FM-UE）对有无反射项目的上肢运动障碍进行定量分析。根据5项研究的基线检测（采用一致的检测程序）汇编的FM-UE单项评分的次要分析。大学和VA研究中心。参与者：慢性卒中（卒中后>6个月）患者（N=-247）。不适用因通过两个分层聚类分析确定的聚类的总FM-UE评分定义的截止评分对FM-UE单个项目评分的全样本进行分析（有/无反射）。运动功能的模式由聚类的总项目分数定义。FM-UE评分范围为2-63（平均值=26.9±15.7）（有反射项目）和0-57（平均值=22.1 ±15.3）（无反射项目）。确定了三个集群。FM-UE评分的分布显示聚类之间有相当大的重叠，因此还推导出四个不同的卒中损伤水平。对于慢性卒中，上肢FM的聚类分析支持三或四损伤级别分类方案。
To quantitatively define levels of upper extremity movement impairment using cluster analysis of Fugl-Meyer upper extremity (FM-UE) with and without reflex items. Secondary analysis of FM-UE individual item scores compiled from baseline testing of 5 studies with consistent testing procedures. University and VA research centers. Participants: Individuals (N=−247) with chronic stroke (>6 months post-stroke). Not applicable. Cut-off scores defined by total FM-UE scores of clusters identified by two hierarchical cluster analyses run on full sample of FM-UE individual item scores (with/without reflexes). Patterns of motor function defined by aggregate item scores of clusters. FM-UE scores ranged from 2–63 (mean=26.9±15.7) with reflex items and 0–57 (mean=22.1 ±15.3) without reflex items. Three clusters were identified. The distributions of the FM-UE scores revealed considerable overlap between the clusters, therefore four distinct stroke impairment levels were also derived. For chronic stroke, the cluster analyses of the upper extremity FM support either a three or a four impairment level classification scheme.
