(1) Background: Observational scales are the most common methodology used to assess postural control and balance in people with stroke. The aim of this paper was to analyse the construct validity of the Postural Assessment Scale for Stroke Patients (PASS) scale in post-stroke patients in the acute, subacute, and chronic stroke phases. (2) Methods: Sixty-one post-stroke participants were enrolled. To analyze the construct validity of the PASS, the following scales were used: the Functional Ambulatory Category (FAC), the Wisconsin Gait Scale (WGS), the Barthel Index (BI) and the Functional Independence Measure (FIM). (3) Results: The construct validity of the PASS scale in patients with stroke at acute phase was moderate with the FAC ( = -0.791), WGS ( = -0.646) and FIM ( = -0.678) and excellent with the BI ( = 0.801). At subacute stage, the construct validity of the PASS scale was excellent with the FAC ( = 0.897), WGS ( = -0.847), FIM ( = -0.810) and BI ( = -0.888). At 6 and 12 months, the construct validity of the PASS with the FAC, WGS, FIM and BI was also excellent. (4) Conclusions: The PASS scale is a valid instrument to assess balance in post-stroke individuals especially, in the subacute and chronic phases (at 6 and 12 months).
(1) 背景：观察量表是评估中风患者姿势控制和平衡最常用的方法。本文旨在分析中风患者姿势评估量表（PASS）在急性、亚急性和慢性中风阶段的结构效度。(2) 方法：招募了61名中风后参与者。为分析PASS的结构效度，使用了以下量表：功能性步行分类（FAC）、威斯康星步态量表（WGS）、巴氏指数（BI）和功能独立性测量（FIM）。(3) 结果：PASS量表在急性期中风患者中与FAC（=-0.791）、WGS（=-0.646）和FIM（=-0.678）的结构效度为中等，与BI（=0.801）的结构效度为优。在亚急性期，PASS量表与FAC（=0.897）、WGS（=-0.847）、FIM（=-0.810）和BI（=-0.888）的结构效度为优。在6个月和12个月时，PASS与FAC、WGS、FIM和BI的结构效度也为优。(4) 结论：PASS量表是评估中风后个体平衡的有效工具，尤其是在亚急性和慢性阶段（6个月和12个月时）。
