腕关节稳定性、腕关节活动度和上肢Fugl-Meyer（W/H UE FM）手部项目的临床管理可能证明是轻度受损卒中幸存者运动障碍的一种严格、易于管理的床边测量方法。本研究的目的是评估项目结构的W/H UE FM使用Rasch分析。采用潜在平行分析、有序因素分析和部分信用模型Rasch分析对轻度受损卒中幸存者临床试验中的W/H UE FM数据进行次要分析。潜在平行分析和有序因素分析表明，所有W/H UE FM项目代表一个单一的一维结构，手腕和手的运动能力。对150例轻度受损卒中幸存者（94例男性;平均年龄57.1 ± 11.4岁;卒中后平均时间19.5个月）的数据进行Rasch分析，结果显示W/H UE FM是腕部和手部运动能力的可靠、有效和有效的测量方法。这些数据与Rasch模型假设兼容，并与以前的W/H UE FM研究一致。质量屈曲和伸展运动是W/H UE FM项目中难度最小的。W/H UE FM非常适合轻度受损的卒中幸存者，这些患者表现出进行大量屈曲和大量伸展运动的能力。对于能力水平较低的卒中幸存者，全量表UE FM可能更可取。
Clinical administration of the wrist stability, wrist mobility, and hand items of the upper extremity Fugl-Meyer (W/H UE FM) may prove a rigorous, easily administered, bedside measure of motor impairment in mildly impaired stroke survivors. The purpose of this study was to evaluate the item-structure of the W/H UE FM using Rasch analysis. Secondary analysis of W/H UE FM data arising from clinical trials of mildly impaired stroke survivors using latent parallel analysis, ordinal factor analysis, and partial credit model Rasch analyses. Latent parallel analysis and ordinal factor analysis indicated that all W/H UE FM items represent a single unidimensional construct, wrist and hand motor ability. Rasch analysis of data from 150 mildly impaired stroke survivors (94 men; mean age, 57.1 ± 11.4y; mean time since stroke, 19.5 months) revealed that the W/H UE FM operated as a reliable, valid, and effective measure of wrist and hand motor ability. These data were compatible with Rasch model assumptions and are consistent with previous W/H UE FM research. Mass flexion and extension movements were the least difficult W/H UE FM items. The W/H UE FM is well suited to mildly impaired stroke survivors who exhibit the ability perform mass flexion and mass extension movements. The full scale UE FM may be preferable for stroke survivors with lower levels of ability.
