The validity of function tests on the upper extremities as prognostic tools in vibration syndrome was evaluated over a sequence of observation periods. The subjects examined were 672 forest workers using chain saws who had had some complaints and who had shown abnormal findings in the function tests. The function tests consisted of peripheral circulatory and sensory tests, including cold provocation and motor tests of functional capacity in the upper extremities. From the results of testing, 23 variables were selected and examined by multivariate analysis. The four principal components were extracted by principal component analysis, and the factor score of the peripheral circulatory disturbances component was found to be highly correlated with the severity of VWF (Vibration-induced White Finger). The course of VWF and the nail compression test had high standard regression coefficients with the severity of vibration syndrome. The course of finger numbness, pinching power, pain threshold, skin temperature and X-ray findings in the elbow joints had high discriminant function values for the evaluation of the severity of vibration syndrome.
在一系列观察期内，对上肢功能测试作为振动综合征预后工具的有效性进行了评估。接受检查的受试者为672名使用电锯的林业工人，他们有一些不适症状，并且在上肢功能测试中显示出异常结果。功能测试包括外周循环和感觉测试，其中有冷激发试验以及上肢功能能力的运动测试。从测试结果中选取了23个变量，并通过多变量分析进行检验。通过主成分分析提取了四个主要成分，发现外周循环障碍成分的因子得分与振动性白指（VWF）的严重程度高度相关。VWF病程和甲床压迫试验与振动综合征严重程度具有较高的标准回归系数。手指麻木病程、捏力、痛阈、皮肤温度和肘关节X线表现对评估振动综合征严重程度具有较高的判别功能值。
