Abstract

INTRODUCTION/AIMS Limitations exist in evaluating mechanical detection thresholds (MDTs) due to a lack of dependable electronic instruments designed to assess Aβ fibers and measure MDTs across different body areas. This study aims to evaluate the test-retest and inter-rater reliability of the cutaneous mechanical stimulator (CMS), an electronic tactile stimulator, in quantifying MDTs. METHODS Using a test-retest design, participants underwent assessments of MDTs using Semmes-Weinstein monofilaments (SWM) and the CMS. This study included 27 healthy volunteers (mean age 24.07 ± 3.76 years). Two raters assessed MDTs using SWM and the CMS at two stimulation sites (the left hand and foot) in two experimental sessions approximately 2 weeks apart. RESULTS MDTs using SWM and the CMS showed excellent reliability on the hand (intraclass correlation coefficient [ICC] = .84) and foot (ICC = .90). A comparison of results obtained at the two sessions showed that MDTs on the hand displayed good reliability for both SWM (ICC = .63) and the CMS (ICC = .73), whereas MDTs on the foot displayed fair reliability for SWM (ICC = .50) and the CMS (ICC = .42). MDTs exhibited good inter-rater reliability with SWM (ICC = .66) and excellent inter-rater reliability with the CMS (ICC = .82) on the hand, as well as showing fair inter-rater reliability with SWM (ICC = .53) and good inter-rater reliability with the CMS (ICC = .60) on the foot. DISCUSSION The CMS showed superior inter-rater reliability, indicating its potential as a valuable tool for assessing tactile sensitivity in research and clinical settings.

测量健康成年人触觉机械检测阈值的两种设备的测试重复可靠性和评分者之间的可靠性：塞姆斯-温斯坦单丝和皮肤机械刺激器。

简介/目的由于缺乏可靠的电子仪器来评估 Aβ 纤维和测量不同身体部位的机械检测阈值 (MDTs)，因此在评估机械检测阈值 (MDTs) 方面存在局限性。本研究旨在评估皮肤机械刺激器（CMS）（一种电子触觉刺激器）在量化 MDTs 方面的重复测试和评分者之间的可靠性。方法采用重复测试设计，参与者使用塞姆斯-温斯坦单丝（SWM）和皮肤机械刺激器进行 MDTs 评估。这项研究包括 27 名健康志愿者（平均年龄为 24.07 ± 3.76 岁）。结果使用 SWM 和 CMS 的 MDT 在手（类内相关系数 [ICC] = .84）和脚（ICC = .90）上显示出极佳的可靠性。对两次测量结果的比较显示，手部的 MDT 在 SWM（ICC = .63）和 CMS（ICC = .73）方面均显示出良好的可靠性，而足部的 MDT 在 SWM（ICC = .50）和 CMS（ICC = .42）方面显示出一般的可靠性。在手部，MDT 与 SWM 的评定者间可靠性良好（ICC = .66），与 CMS 的评定者间可靠性极佳（ICC = .82）；在足部，MDT 与 SWM 的评定者间可靠性一般（ICC = .53），与 CMS 的评定者间可靠性良好（ICC = .60）。

期刊介绍： Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified. Appearing monthly, Muscle & Nerve publishes clinical studies and clinically relevant research reports in the fields of anatomy, biochemistry, cell biology, electrophysiology and electrodiagnosis, epidemiology, genetics, immunology, pathology, pharmacology, physiology, toxicology, and virology. The Journal welcomes articles and reports on basic clinical electrophysiology and electrodiagnosis. We expedite some papers dealing with timely topics to keep up with the fast-moving pace of science, based on the referees'' recommendation.
