Abstract

Background and Aims

The Inflammatory Rasch-built Overall Disability Scale (I-RODS) is an effective activity measure for use in inflammatory peripheral neuropathy. The aim of this study was to validate the Korean version of the I-RODS in patients with chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain-Barré syndrome (GBS), anti-myelin-associated glycoprotein (MAG) neuropathy, and autoimmune nodopathy.

Methods

A total of 120 patients underwent clinical evaluations, which included the I-RODS, Inflammatory Neuropathy Cause and Treatment (INCAT) assessment, and Jamar grip strength (kg) measurement. Follow-up assessments were performed for 83 patients during their regular clinic visits. To estimate the test–retest reliability of the I-RODS, the scale was reapplied to a subset of 16 patients within 2–7 days of the initial test. Overall, reliability, validity, and responsiveness of the I-RODS were evaluated.

Results

Internal consistency was good, as indicated by a person separation index of 0.966. The raw and standardized Cronbach's alpha values were both 0.974. The test–retest reliability analyzed using the intraclass correlation coefficient (ICC) was also high (ICC = 0.972). The I-RODS showed a strong correlation with INCAT scores (ρ = −0.81, p < .001) and a moderate correlation with grip strength (ρ = 0.61, p < .001). Furthermore, the sensitivity for detecting clinically meaningful improvement was highest for grip strength (60.4%) followed by I-RODS (52.1%), while for capturing deterioration, it was highest for I-RODS (80.0%).

Interpretation

The Korean version of the I-RODS is a reliable and valid tool for measuring disability in patients with inflammatory neuropathy. The I-RODS is useful for both clinical practice and research applications.

韩式炎性rasch量表在炎性神经病变患者中的应用验证。

背景和目的：炎症性拉希德构建的整体残疾量表（I-RODS）是一种用于炎性周围神经病变的有效活动测量方法。本研究的目的是验证韩国版I-RODS在慢性炎症性脱髓鞘多神经病变（CIDP）、格林-巴勒综合征（GBS）、抗髓鞘相关糖蛋白（MAG）神经病变和自身免疫性淋巴结病患者中的应用。方法：对120例患者进行临床评估，包括i - rod、炎症性神经病变病因与治疗（INCAT）评估和Jamar握力（kg）测量。对83例患者在常规门诊就诊期间进行随访评估。为了估计I-RODS的重测可靠性，在初始测试后2-7天内将量表重新应用于16名患者的子集。总体而言，评估了i - rod的信度、效度和反应性。结果：内部一致性好，人分离指数为0.966。原始和标准化Cronbach’s alpha值均为0.974。用类内相关系数（ICC）分析的重测信度也很高（ICC = 0.972）。I-RODS与INCAT评分有很强的相关性（ρ = -0.81, p）解释：韩国版I-RODS是测量炎症性神经病变患者残疾的可靠有效工具。I-RODS对临床实践和研究应用都很有用。

期刊介绍： The Journal of the Peripheral Nervous System is the official journal of the Peripheral Nerve Society. Founded in 1996, it is the scientific journal of choice for clinicians, clinical scientists and basic neuroscientists interested in all aspects of biology and clinical research of peripheral nervous system disorders. The Journal of the Peripheral Nervous System is a peer-reviewed journal that publishes high quality articles on cell and molecular biology, genomics, neuropathic pain, clinical research, trials, and unique case reports on inherited and acquired peripheral neuropathies. Original articles are organized according to the topic in one of four specific areas: Mechanisms of Disease, Genetics, Clinical Research, and Clinical Trials. The journal also publishes regular review papers on hot topics and Special Issues on basic, clinical, or assembled research in the field of peripheral nervous system disorders. Authors interested in contributing a review-type article or a Special Issue should contact the Editorial Office to discuss the scope of the proposed article with the Editor-in-Chief.
