研究背景对偏瘫患者的上肢运动功能进行定量评估具有重要意义。目的研究偏瘫患者可达工作空间的特点，评价其在脑卒中患者中的效度、信度、测量误差和反应性。设计：一项描述性、重复测量、观察性研究。评估偏瘫和非偏瘫UE的RWS，并通过将偏瘫UE的RWS除以非偏瘫UE的RWS来确定RWS比率。RWS的同时效度通过检查与Fugl-Meyer评估UE运动评分的关系来确定。对40名受试者进行了重测可重复性检验。对32名受试者在强化训练前和训练后3周的RWS成绩进行检测。结果RWS肩部下部面积明显大于上部，RWS肩部内下部面积明显大于外侧下部。RWS比率与Fugl-Meyer UE运动评分高度相关(r=0.81)。RWS比值具有较好的内部相对信度(组内相关系数=0.94)，无固定偏倚或比例偏倚。RWS比值的最小可检测变化为16.6。RWS量表的反应度较大(标准化回答均数t=0.83)。局限性未对检查者间信度进行评估。结论RWS量表在脑卒中偏瘫患者中具有足够的效度、信度和反应性。基于深度传感器的RWS评估对于临床环境下的轻瘫UE运动功能的可视化和量化是有用的。
BackgroundQuantitative evaluation of upper extremity (UE) motor function is important in people with hemiparetic stroke. A depth sensor–based assessment of reachable work space (RWS) was applied to visualize and quantify paretic UE motor function.ObjectiveThe objectives of this study were to examine the characteristics of RWS and to assess its validity, reliability, measurement error, and responsiveness in people with hemiparetic stroke.DesignThis was a descriptive, repeated-measures, observational study.MethodsFifty-eight people with stroke participated. RWS was assessed on both paretic and nonparetic UEs, and the RWS ratio was determined by dividing the RWS of the paretic UE by that of the nonparetic UE. The concurrent validity of the RWS was determined by examining the relationship with the Fugl-Meyer Assessment UE motor score. Test-retest reproducibility was examined in 40 participants. Responsiveness was determined by examining the RWS results before and after 3 weeks of intensive training of the paretic UE in 32 participants.ResultsThe lower area of RWS bordering shoulder was significantly larger than the upper area, and the medial-lower area of RWS bordering shoulder was significantly larger than the lateral-lower area. The RWS ratio was highly correlated with the Fugl-Meyer Assessment UE motor score (r= 0.81). The RWS ratio showed good intrarater relative reliability (intraclass correlation coefficient = 0.94) and no fixed or proportional bias. The minimal detectable change of the RWS ratio was 16.6. The responsiveness of the RWS ratio was large (standardized response mean = 0.83).LimitationsInterexaminer reliability was not assessed.ConclusionsThe RWS assessment showed sufficient validity, reliability, and responsiveness in people with hemiparetic stroke. A depth sensor–based RWS evaluation is useful for visualizing and quantifying paretic UE motor function in the clinical setting.
