对振动性白指的实验方法曾有过许多报道,但这些方法的可靠性尚未得到证实。本文对常用的冷水试验和反应性充血试验进行了可靠性和有效性研究。作者选择10名从事室内非振动作业的健康男性自愿者为非暴露组,进行冷水试验和反应性充血试验。每人每周进行一次,共10周,两试验间隙至少为2小时,用于研究两项试验的可靠性。另以52名接触手臂振动的工人为暴露组,并按症状有 There have been many reports of experimental methods of vibrating white fingers, but the reliability of these methods has not been confirmed. In this paper, the reliability and validity of commonly used cold water test and reactive hyperemia test were studied. The authors selected 10 healthy male volunteers who did non-vibration work indoors as non-exposed group and conducted cold water test and reactive hyperemia test. Per person per week for 10 weeks with a minimum of 2 hours between test runs to study the reliability of both trials. The other 52 workers exposed to the arm vibration were exposed group, and according to the symptoms
