Abstract

Objectives: Early detection of neurosensory injury among workers exposed to hand-arm vibration is crucial. The aim of our study was to evaluate the diagnostic test performance of clinical point-of-care testing using a tuning fork and temperature rollers in relation to vibrotactile and thermal quantitative sensory testing.

Methods: We recruited 225 vibration-exposed workers who underwent clinical point-of-care testing using a Rydel Seiffer tuning fork and temperature rollers (25 and 40°C) applied to the distal phalanges of the index and little fingers bilaterally. Quantitative sensory testing was conducted at the same locations. Sensitivity, specificity, and other measures of diagnostic test performance were calculated.

Results: The study sample consisted of 208 men and 17 women with a median (IQR) age of 38 (26) years and with a median (IQR) hand-arm vibration exposure duration of 12 (21) years. Using vibrotactile quantitative sensory testing as the reference method, the sensitivity for the Rydel Seiffer tuning fork to detect reduced perception of vibration ranged from 30.0 to 61.1%, depending on the tested finger. The corresponding values for specificity were 91.1 to 94.4%. The sensitivity of temperature roller discrimination in relation to warm detection thresholds ranged from 31.6 to 48.2% and the specificity from 82.7 to 87.5%. The corresponding sensitivity of temperature roller discrimination in relation to cold detection thresholds ranged from 28.9 to 42.5% and the specificity from 86.0 to 94.7%.

Conclusions: The sensitivity of clinical point-of-care testing was rather low, indicating that quantitative sensory testing add value to the diagnostic procedure.

临床护理点测试与定量感觉测试对暴露于手臂振动的工人的神经感觉损伤的诊断测试表现。
目的:早期发现工人暴露于手臂振动的神经感觉损伤是至关重要的。我们研究的目的是评估临床护理点测试使用音叉和温度滚轮的诊断测试性能与振动触觉和热定量感官测试的关系。方法:我们招募了225名暴露于振动的工人,他们接受了临床护理点测试,使用Rydel Seiffer音叉和温度滚轮(25°C和40°C)应用于双侧食指和小指的远端指骨。在相同位置进行定量感官测试。计算敏感性、特异性和其他诊断测试性能指标。结果:研究样本包括208名男性和17名女性,中位年龄(IQR)为38(26)岁,中位手臂振动暴露时间(IQR)为12(21)年。以振动触觉定量感官测试作为参考方法,根据被测手指的不同,Rydel Seiffer音叉检测振动减少感知的灵敏度在30.0% ~ 61.1%之间。特异性对应值为91.1 ~ 94.4%。温度辊识别对温度检测阈值的敏感性为31.6 ~ 48.2%,特异性为82.7 ~ 87.5%。温度辊识别对低温检测阈值的敏感性为28.9 ~ 42.5%,特异性为86.0 ~ 94.7%。结论:临床即时检测的敏感性较低,说明定量感觉检测对诊断有一定的价值。

期刊介绍: The scope of the journal is broad, covering toxicology, ergonomics, psychosocial factors and other relevant health issues of workers, with special emphasis on the current developments in occupational health. The JOH also accepts various methodologies that are relevant to investigation of occupational health risk factors and exposures, such as large-scale epidemiological studies, human studies employing biological techniques and fundamental experiments on animals, and also welcomes submissions concerning occupational health practices and related issues.
