Abstract

Introduction: Upper limb dysfunction is common in people with Parkinson's. This study aimed to pilot and establish the initial psychometric properties of the timed upper limb assessment (TULA), a 10-item timed functional upper limb assessment tool.

Method: A prospective observational study was conducted with 381 participants (202 with Parkinson's, 179 controls). The TULA was administered to both groups, with inter-rater reliability assessed in a subset (n = 47). Principal component analysis examined structural validity, while convergent validity was explored through correlations with cognitive and motor assessments.

Results: The TULA demonstrated high internal consistency (Cronbach's α = 0.81 for Parkinson's group) and high inter-rater reliability (intraclass correlation coefficient (ICC) > 0.9). People with Parkinson's took significantly longer to complete all items (mean (SD) 22.2 ± 7.5) compared to controls (16.8 ± 3.7, p < 0.001). The tool showed moderate correlation with the timed up and go test (r = 0.56, p < 0.001), a significant low correlation with the Hoehn and Yahr Scale (r = 0.44, p ⩽ 0.001) and a significant low correlation with both the Montreal Cognitive Assessment (r = -0.37, p ⩽ 0.001) and the Mini Mental Status Examination (r = -0.31, p ⩽ 0.001).

Conclusion: This study provides an alternative functional upper limb assessment tool for people with Parkinson's attending occupational therapy. Initial data have been provided to support the reliability and validity of the TULA.

老年帕金森病患者上肢时间评估的发展和初始心理测量学特征。

上肢功能障碍在帕金森氏症患者中很常见。本研究旨在初步建立一套包含10个项目的定时上肢功能评估工具（TULA）的初始心理测量特性。方法：对381名参与者进行前瞻性观察研究（202名帕金森病患者，179名对照组）。两组均采用TULA，并在一个子集（n = 47）中评估了评分者间的可靠性。主成分分析检验结构效度，而聚合效度通过认知和运动评估的相关性来探索。结果：TULA具有较高的内部一致性（帕金森组Cronbach′s α = 0.81）和较高的组间信度（类内相关系数(ICC) > 0.9）。与对照组（16.8±3.7,p r = 0.56, p r = 0.44, p < 0.001）相比，帕金森病患者完成所有项目所需的时间明显更长（平均（SD） 22.2±7.5），与蒙特利尔认知评估（r = -0.37, p < 0.001）和迷你精神状态检查（r = -0.31, p < 0.001）的相关性都很低。结论：本研究为帕金森病患者参加职业治疗提供了另一种上肢功能评估工具。已经提供了初步数据来支持TULA的可靠性和有效性。

期刊介绍： British Journal of Occupational Therapy (BJOT) is the official journal of the Royal College of Occupational Therapists. Its purpose is to publish articles with international relevance that advance knowledge in research, practice, education, and management in occupational therapy. It is a monthly peer reviewed publication that disseminates evidence on the effectiveness, benefit, and value of occupational therapy so that occupational therapists, service users, and key stakeholders can make informed decisions. BJOT publishes research articles, reviews, practice analyses, opinion pieces, editorials, letters to the editor and book reviews. It also regularly publishes special issues on topics relevant to occupational therapy.
