背景和目的---很少有专门为中风患者设计的用于姿势能力评估的临床工具。方法脑卒中患者姿势评定量表（PASS）是由BL运动评定量表（BL Motor Assessment）改编而成的，主要有3个方面：（1）必须评定患者保持给定姿势和改变姿势时保持平衡的能力;（2）量表应适用于所有患者，即使是那些姿势表现非常差的患者;（3）量表应包含难度递增的项目。本量表在70例脑卒中患者发病后第30天和第90天进行了验证，结果：在30名年龄匹配的健康受试者中获得了规范性数据，PASS符合以下要求：（1）良好的结构效度;与伴随的功能独立性测量（functional independence Measure，FMD）评分高度相关（r = 0.73，P = 10（-6）），与下肢运动功能评分（r = 0.78，P < 10（-6）），并与姿势稳定性的仪器测量（2）良好的预测效度：第30天PASS评分与第90天的RISK评分高度相关（r = 0.75，P < 10（-6））;（3）内部一致性高（克朗巴赫α系数= 0.95）;（4）较高的评分者间信度和重测信度（平均kappa值分别为0.88和0.72）。我们的结果证实，PASS是第一次中风患者姿势控制最有效、最可靠的临床评估之一中风后3个月。
Background and Purpose-Few clinical tools available for assessment of postural abilities are specifically designed for stroke patients. Most have major floor or ceiling effects, and their metrological properties are not always completely known.Methods-The Postural Assessment Scale for Stroke patients (PASS), adapted from the BL Motor Assessment, was elaborated in concordance with 3 main ideas: (1) the ability to maintain a given posture and to ensure equilibrium in changing position both must be assessed; (2) the scale should be applicable for all patients, even those with very poor postural performance; and (3) it should contain items with increasing difficulty. This new scale has been validated in 70 patients tested on the 30th and 90th days after stroke onset.Results-Normative data obtained in 30 age-matched healthy subjects are presented, The PASS meets the following requirements: (1) good construct validity: high correlation with concomitant Functional Independence Measure (FIM) scores (r = 0.73, P = 10(-6)), with lower-limb motricity scores (r = 0.78, P < 10(-6)), and with an instrumental measure of postural stabilization (r = 0.48, P < 10(-2)); (2) excellent predictive validity: high correlation between PASS scores on the 30th day and FIM scores on the 90th day (r = 0.75, P < 10(-6)); (3) high internal consistency (Cronbach alpha-coefficient = 0.95); and (4) high interrater and test-retest reliabilities (average kappa = 0.88 and 0.72).Conclusions-Our results confirm that the PASS is one of the most valid and reliable clinical assessments of postural control in stroke patients during the first 3 months after stroke.
