目的：开发一种上肢假肢使用者活动表现的自我报告测量方法，根据截肢水平和假肢类型量化结果。材料与方法对423例主要上肢截肢（ULA）使用假体的成人患者进行电话调查。项目生成、认知测试和试点测试之后是现场测试。项目被分类为单手或双手。因子分析和Rasch分析评估了单维性、单调性、项目拟合、差异项目功能（DIF）和可靠性。用类内相关系数（ICCs）评价重测信度。已知组效度采用方差分析评估。结果单侧ULA患者使用假体完成单侧任务的24%和双侧任务的38%。双侧ULA患者使用假体完成64%的单侧任务和46%的双侧任务。因子分析发现单手任务因子（CFI = 0.963, TLI = 0.950, RMSEA = 0.064）和双手任务因子（CFI = 0.958, TLI = 0.953, RMSEA = 0.053）。响应类别被折叠以解决单调性问题。经DIF调整后，单手和双手任务量表的人信度分别为0.49和0.82，ICCs分别为0.88和0.91。两种量表在截肢程度上存在差异（p< 0.001）。结论义肢使用者上肢功能量表（ufs - p）对义肢使用者上肢功能的测量具有良好的心理测量特性。截肢者上肢功能的测量具有挑战性，因为目前可用的测量方法不能明确地对假肢的活动表现进行分级。假肢使用者上肢功能量表（ufs - p）建立在原始的矫形术和假肢用户调查（OPUS） UEFS量表的基础上，修改了说明，修订了项目集，反应类别和评分算法。ufs - p量表由单手任务量表和双手任务量表两个维度组成。ufs - p量表比现有的上肢功能自我报告量表有明显的优势，后者询问在不考虑假体使用的情况下进行功能活动的困难程度，并且不区分使用和不使用假体的人。
PurposeTo develop a self-report measure of activity performance for upper limb prosthesis users that quantifies outcomes by level of amputation and prosthesis type.Materials and methodsTelephone survey of 423 adults with major upper limb amputation (ULA) who used a prosthesis. Item generation, cognitive, and pilot testing were followed by field testing. Items were categorized as one- or two-handed. Factor and Rasch analyses evaluated unidimensionality, monotonicity, item fit, differential item functioning (DIF), and reliability. Test–retest reliability was evaluated with intraclass correlation coefficients (ICCs). Known group validity was assessed with ANOVAs.ResultsRespondents with unilateral ULA utilized prosthesis for 24% of unilateral and 38% of bilateral tasks. Those with bilateral ULA utilized prostheses for 64% of unilateral and 46% of bilateral tasks. Factor analyses identified a One-handed Task factor (CFI = 0.963, TLI = 0.950, and RMSEA = 0.064) and a Two-Handed Task factor (CFI = 0.958, TLI = 0.953, and RMSEA = 0.053). Response categories were collapsed to address monotonicity. After DIF adjustment, person reliability was 0.49 and 0.82 for One-handed and Two-handed Task scales, respectively, and ICCs were 0.88 and 0.91. Both scales differed by amputation level (p< 0.001).ConclusionsThe Upper Extremity Functional Scale for Prosthesis Users (UEFS-P) measure of upper limb function of prosthesis users has promising psychometric properties.Implications for rehabilitationMeasurement of upper limb function in persons with amputation is challenging, given currently available measures which do not explicitly grade activity performance with a prosthesis.The Upper Extremity Functional Scale for Prosthesis Users (UEFS-P) builds upon the original Orthotics and Prosthetics User Survey (OPUS) UEFS Scale with modified instructions, a revised item set, response categories and scoring algorithm.The UEFS-P consists of two unidimensional scales, the One-handed Tasks scale and the Two-handed Tasks scale.The UEFS-P scales have clear advantages over existing self-report measures of upper limb function that ask about difficulty with performing functional activities without accounting for prosthesis use, and do not differentiate persons who use and do not use a prosthesis.
