背景和目的：Tinetti运动能力评估（POMA）通常用于测量老年人的平衡能力。本研究的目的是确定的重测信度和最小可检测变化（MDC）的POMA，并探讨其横截面和纵向结构效度用于人中风后早期afterstrok.Methods：参与者被招募，如果他们有第一个记录中风，并在住院康复期间接受物理治疗。在入院和住院康复出院时收集POMA、步态速度和运动功能独立性测量（FIM）评分。在第一次试验后1天进行POMA的第二次试验，以进行可靠性分析。相关性（斯皮尔曼rho）之间的原始分数的入院和出院结果的措施，以及在入院和出院之间的分数变化，被用来探讨POMA的结构效度。55人，平均年龄75 +/- 11岁，首次记录中风的患者参加了研究，并在中风后平均8 +/-5天开始住院物理治疗。重测信度的组内相关系数（ICC 2，1）为0.84，MDC为6分。POMA评分与入院时（rs = 0.55和0.70）和出院时（r（s）= 0.55和0.82）的运动速度和步态速度评分中度相关。所有3个措施的变化分数有一个公平的相关性（rs = 0.28-0.51）。讨论和结论：重测信度和MDC的POMA在中风的人是类似于以前的研究在老年人长期护理居民。结果支持横截面和纵向结构效度的POMA在中风后早期的人，并证明有效性和可靠性，以衡量在这一人群的平衡能力。
Background and Purpose: The Tinetti Performance-Oriented Mobility Assessment (POMA) is commonly used to measure balance ability in older adults. The purpose of this study was to determine the test-retest reliability and minimal detectable change (MDC) of the POMA and explore its cross-sectional and longitudinal construct validity for use in people early after stroke.Methods: Participants were recruited if they had a first documented stroke and were receiving physical therapy during inpatient rehabilitation. The POMA, gait speed, and motor Functional Independence Measure (FIM) scores were collected at admission and at discharge from inpatient rehabilitation. A second trial of the POMA was conducted 1 day after the first trial for reliability analysis. Correlations (Spearman rho) between raw scores of admission and discharge outcome measures, as well as change in scores between admission and discharge, were used to explore the construct validity of the POMA.Results: Fifty-five people, with average age of 75 +/- 11 years, who had experienced first documented stroke participated in the study and began inpatient physical therapy at a mean of 8 +/- 5 days poststroke. Test-retest reliability intraclass correlation coefficient (ICC2,1) was 0.84 and MDC was 6 points. The POMA scores were moderately correlated to motor FIM and gait speed scores at admission (rs = 0.55 and 0.70) and discharge (r(s) = 0.55 and 0.82.) Change scores of all 3 measures had a fair correlation (rs = 0.28-0.51).Discussion and Conclusions: Test-retest reliability and MDC of the POMA in people with stroke is similar to previous research in older adult long-term care residents. Results support cross-sectional and longitudinal construct validity of the POMA in persons early after stroke and demonstrate validity and reliability to measure balance ability in this population.
