To assist occupational health professionals to interpret the results of standardised tests for components of the hand-arm vibration syndrome by presenting data for healthy subjects and identifying the effects of some of the confounding variables.
Thermal thresholds, vibrotactile thresholds, the finger skin temperature (FST) response to cold provocation and percentage finger systolic blood pressures (%FSBP) were measured by standardised procedures. Normative data were obtained for healthy men of working age (17-62 years) during 237 experimental sessions encompassing ten different studies. Hot thermal thresholds and cold thermal thresholds were assessed independently with 38 subjects; 152 measurements of both hot and cold thresholds were made. Vibrotactile thresholds were measured at several locations on 81 subjects, giving a total of 216 measurements at 125 Hz and at 31.5 Hz. The FST response to cold provocation at 15 degrees C was monitored by thermocouples throughout a 2-min settling period, a 5-min immersion period and a 10-min recovery period. A total of 302 measurements was made on 70 subjects. The %FSBPs were measured in four test fingers and one reference finger by strain-gauge plethysmography. Measurements were made on 97 subjects. A total of 351 measurements was made at 15 degrees C, with 341 measurements at 10 degrees C.
Normative data and some example normal limits are presented from the current data set and from data presented in other studies. Age was found to influence thermal thresholds, vibrotactile thresholds and the FST response to cold provocation; older subjects exhibited deteriorated vascular and neurological function. Room temperature was found to influence %FSBPs and the FST response to cold provocation; warmer environments resulted in improved vascular response to cold. Outdoor temperature had a small effect on the FST response to cold provocation and on the vibrotactile thresholds. Thermal thresholds showed some influence of smoking habits and of the FST measured prior to testing. For all four tests, any differences between measurement locations were small and there were no differences between left-handed and right-handed subjects.
The current data can assist occupational health professionals to interpret the results of the standardised tests. Comparison with the current data is considered valid for men of working age. Age and room temperature should be recognised as being capable of causing changes in neurological and vascular function.
通过提供健康受试者的数据并确定一些混杂变量的影响，协助职业健康专业人员解读手臂振动综合征各组成部分标准化测试的结果。
采用标准化程序测量热阈值、振动触觉阈值、手指皮肤温度（FST）对冷刺激的反应以及手指收缩压百分比（%FSBP）。在包括十项不同研究的237次实验过程中，获取了工作年龄（17 - 62岁）健康男性的标准数据。38名受试者分别独立评估热阈值和冷阈值；对热阈值和冷阈值进行了152次测量。在81名受试者的多个部位测量振动触觉阈值，在125Hz和31.5Hz下共进行了216次测量。在整个2分钟稳定期、5分钟浸泡期和10分钟恢复期内，通过热电偶监测15摄氏度时FST对冷刺激的反应。对70名受试者共进行了302次测量。通过应变片体积描记法在四个测试手指和一个参考手指上测量%FSBP。对97名受试者进行了测量。在15摄氏度下共进行了351次测量，在10摄氏度下进行了341次测量。
从当前数据集以及其他研究提供的数据中给出了标准数据和一些示例正常范围。发现年龄会影响热阈值、振动触觉阈值以及FST对冷刺激的反应；年龄较大的受试者血管和神经功能有所下降。发现室温会影响%FSBP以及FST对冷刺激的反应；温度较高的环境会使血管对寒冷的反应得到改善。室外温度对FST对冷刺激的反应和振动触觉阈值有较小影响。热阈值显示出吸烟习惯和测试前测量的FST的一些影响。对于所有四项测试，测量部位之间的任何差异都很小，左撇子和右撇子受试者之间没有差异。
当前数据可协助职业健康专业人员解读标准化测试的结果。与当前数据进行比较对于工作年龄的男性被认为是有效的。年龄和室温应被视为能够引起神经和血管功能变化的因素。
