To assess upper extremity (UE) capabilities following stroke, the Wolf Motor Function Test (WMFT) measures time to complete 15 UE tasks and 2 strength tasks, but takes 30 to 45 minutes for the clinician to complete.
In an effort to streamline the WMFT, this study evaluated the association between the magnitude of improvement on any timed task of the WMFT and the change score on all other tasks among participants in the Extremity Constraint Induced Therapy Evaluation (EXCITE) trial.
This association was evaluated using regression methods according to chronicity and controlling for key covariates (functional level, gender, concordance) for log mean WMFT scores.
After controlling for covariates, 6 tasks (hand to table [front], hand to box [front], reach and retrieve, lift can, lift pencil, and fold towel) influenced the overall WMFT score for survivors meeting EXCITE criteria and treated within 3 to 9 months poststroke. Six different tasks (extend elbow weight, hand to box [front], lift can, lift pencil, turn key in lock, and fold towel) influenced the overall WMFT score for those receiving constraint-induced movement therapy (CIMT) 1 year later. The importance of certain tasks relative to others may best represent overall UE function, but this streamlining enables the clinician to prioritize these tasks in the evaluation.
The delineation of those tasks depends on the time poststroke from enrollment to CIMT. This study demonstrates that the WMFT can be streamlined from 17 to 6 tasks.
为评估中风后上肢（UE）功能，狼运动功能测试（WMFT）测量完成15项UE任务和2项力量任务所需的时间，但临床医生完成该测试需要30至45分钟。
为简化WMFT，本研究评估了肢体约束诱导疗法评估（EXCITE）试验参与者中，WMFT任何定时任务的改善幅度与所有其他任务变化分数之间的关联。
根据病程，采用回归方法评估这种关联，并对log平均WMFT分数的关键协变量（功能水平、性别、一致性）进行控制。
在控制协变量后，6项任务（手到桌子[前方]、手到盒子[前方]、伸手取物、举起罐子、举起铅笔和折叠毛巾）影响了符合EXCITE标准且在中风后3至9个月内接受治疗的幸存者的总体WMFT分数。6项不同的任务（伸展肘部负重、手到盒子[前方]、举起罐子、举起铅笔、转动锁中的钥匙和折叠毛巾）影响了1年后接受约束诱导运动疗法（CIMT）的患者的总体WMFT分数。某些任务相对于其他任务的重要性可能最能代表整体UE功能，但这种简化使临床医生能够在评估中对这些任务进行优先排序。
这些任务的划分取决于从中风登记到接受CIMT的时间。本研究表明，WMFT可从17项任务简化为6项任务。
