OBJECTIVE Seated balance (SB) is substantially compromised and greatly impacts the function of individuals living with a spinal cord injury (SCI). A clinically applicable gold standard measure for SB does not exist for this population. Initial validation and reliability analysis of the Function in Sitting Test (FIST) in SCI has been published but the authors of this study report that modifications to the tool may be necessary. This study aimed to explore the psychometrics and clinical utility of a modified version of the FIST to better measure SCI-specific functional tasks in sitting. DESIGN The FIST was modified (FIST-SCI) by an expert panel and used by two graders to evaluate the SB of individuals with chronic SCI (cSCI) on two separate days. The Motor Assessment Scale item 3 (MAS-SCI) was included as a comparison measure. SETTING Research Facility PARTICIPANTS: Individuals with cSCI (>1 year) participated in the study (n=38). Injury levels of individuals participating in this study spanned C1 to T10 (AIS A: 17 subjects, B: 12 subjects, and C: 9 subjects). Thirteen individuals required assistance to transfer. INTERVENTIONS na MAIN OUTCOME MEASURES: Validity, Reliability, Internal Consistency, Sensitivity, Specificity, Responsiveness RESULTS: Validity testing found a moderate relationship between the MAS-SCI and the FIST-SCI (rs: .522, p< .05). FIST-SCI scores distinguished individuals requiring assistance to transfer from those who were independent (t=4.51, p<.05). Inter-rater and intra-rater reliability was excellent (ICC(2,k)= .985, .983, respectively) and internal consistency was excellent (α =.94). A FIST-SCI cut-off score of 45 or greater was 92% sensitive and specific in characterizing transfer ability. SEM (1.3) and MDC (3.5) were similar to previous work. CONCLUSION Initial validity of the FIST-SCI is reported but further assessment is required. Reliability is excellent in the cSCI population. FIST-SCI scores provide clinical insight into the seated functional ability of individuals with cSCI.

慢性 SCI 患者坐位测试功能修改版本的心理测量测试和临床效用

目的 坐姿平衡 (SB) 严重受损，严重影响脊髓损伤 (SCI) 患者的功能。对于该人群，不存在临床适用的 SB 黄金标准衡量标准。SCI 中坐位测试功能 (FIST) 的初步验证和可靠性分析已经发表，但本研究的作者报告说，可能需要对该工具进行修改。本研究旨在探索改良版 FIST 的心理测量学和临床效用，以更好地测量坐姿时 SCI 特定的功能性任务。设计 FIST 由专家小组修改 (FIST-SCI)，并由两名评分者用于在两个不同的日子评估慢性 SCI (cSCI) 个体的 SB。包括运动评估量表第 3 项（MAS-SCI）作为比较措施。设置研究机构参与者：cSCI 患者（>1 年）参与了研究（n=38）。参与本研究的个体的损伤水平跨越 C1 到 T10（AIS A：17 名受试者，B：12 名受试者，C：9 名受试者）。13 个人需要协助才能转移。主要结果指标的干预措施：有效性、可靠性、内部一致性、敏感性、特异性、响应性 结果：有效性测试发现 MAS-SCI 和 FIST-SCI 之间存在中等关系（rs：.522，p<.05）。FIST-SCI 评分区分需要帮助的个体从独立个体转移（t=4.51，p<.05）。评分者间和评分者内的可靠性非常好（分别为 ICC(2,k)= .985, .983），内部一致性非常好（α = .94）。45 或更高的 FIST-SCI 截止分数在表征转移能力方面的敏感性和特异性为 92%。SEM (1.3) 和 MDC (3.5) 与之前的工作相似。结论 报告了 FIST-SCI 的初始有效性，但需要进一步评估。cSCI 人群的可靠性非常好。FIST-SCI 评分提供了对 cSCI 患者坐姿功能能力的临床洞察。
