Abstract

Objectives: This study aims to investigate the validity, reliability and clinimetric features of the Duruöz Hand Index (DHI) in patients with lateral epicondylitis.

Patients and methods: Between October 2019 and January 2020, a total of 78 patients (28 males, 50 females; mean age: 46.4±9.4 years; range, 20 to 65 years) who presented with pain in the forearm and were diagnosed with lateral epicondylitis were included in the study. The patients were evaluated using the Visual Analog Scale (VAS), Health Assessment Questionnaire (HAQ), the Patient-Rated Tennis Elbow Evaluation Questionnaire (PRTEEQ), the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire at Weeks 0, 1 and 4. The DHI reliability (Cronbach alpha, intraclass correlation [ICC]), validity and factor analyses were performed with the data of 70 and 49 patients who attended to follow-up visit at Weeks 1 and 4. The effect size (ES), standard response mean (SRM), and minimum detectable change (MDC) values of the DHI were calculated.

Results: Of the patients, 84.6% were right-handed. The ICC coefficients of DHI were found to be perfect with the test-retest method (ICC; total=0.943). It showed a well-excellent consistency with the internal consistency method (Cronbach alpha; total=0.90). In the structural validity of the DHI, it was very strongly correlated with the DASH (r=0.801; p<0.01), strongly correlated with the PRTEEQ and HAQ total scores (r=0.793; p<0.01; r=0.785; p<0.01), and acceptably correlated with PRTEEQ pain score (r=0.570; p<0.01). The DHI was acceptably correlated with the VAS and grip strength as measured by the hand dynamometer (p<0.05). In our study, three main factors were obtained and MDC and responsiveness sensitivity were found to be moderate (MDC=4.4; SEM=1.61; ES=0.246 p<0.001; SRM=0.538 p<0.001).

Conclusion: Duruöz Hand Index is a reliable, valid, and practical functional assessment scale in patients with lateral epicondylitis.

Duruöz手部指数在外上髁炎患者中的效度和信度。

目的:本研究旨在探讨Duruöz手部指数(DHI)在外上髁炎患者中的效度、信度和临床特征。患者与方法:2019年10月~ 2020年1月，共78例患者(男28例，女50例;平均年龄:46.4±9.4岁;范围为20至65岁)，表现为前臂疼痛并被诊断为外侧上髁炎的患者被纳入研究。于第0、1、4周采用视觉模拟量表(VAS)、健康评估问卷(HAQ)、患者评分网球肘评估问卷(PRTEEQ)、臂、肩、手功能障碍问卷(DASH)对患者进行评估。对70例和49例在第1周和第4周随访的患者进行DHI信度(Cronbach alpha, class内相关性[ICC])、效度和因子分析。计算DHI的效应量(ES)、标准响应平均值(SRM)和最小可检测变化(MDC)值。结果:84.6%的患者为右撇子。用重测法(ICC;总= 0.943)。与内部一致性法(Cronbach alpha;总= 0.90)。在DHI的结构效度上，DHI与DASH呈极强相关(r=0.801;结论:Duruöz手部指数是一种可靠、有效、实用的外上髁炎功能评估量表。

期刊介绍： The Archives of Rheumatology is an official journal of the Turkish League Against Rheumatism (TLAR) and is published quarterly in March, June, September, and December. It publishes original work on all aspects of rheumatology and disorders of the musculoskeletal system. The priority of the Archives of Rheumatology is to publish high-quality original research articles, especially in inflammatory rheumatic disorders. In addition to research articles, brief reports, reviews, editorials, letters to the editor can also be published. It is an independent peer-reviewed international journal printed in English. Manuscripts are refereed by a "double-blind peer-reviewed" process for both referees and authors. Editorial Board of the Archives of Rheumatology works under the principles of The World Association of Medical Editors (WAME), the International Council of Medical Journal Editors (ICMJE), and Committee on Publication Ethics (COPE).
