震动病首先由Loriga(1911)和Hamilton(1918)发现和报道,是一种某些行业中较常见的职业病.引起震动病的原因是长期接触频率在25～35赫兹以上的震动.震动频率愈高,幅度(即能量)愈大,愈容易致病.寒冷、噪音、疲劳、紧张的姿势可降低对震动的耐受性,耐受性存在个体差异.因此病的发生可在接触震动6～9个月之后,但有早至1个月和晚至数十年以后者,有些接触 Shock disease was first discovered and reported by Loriga (1911) and Hamilton (1918) and is a common occupational disease in some industries. The cause of shock disease is the long-term exposure to vibration at frequencies above 25-35 Hz. High, the magnitude (ie, energy) is greater, the more likely to cause disease.Cold, noise, fatigue, stressful posture can reduce the vibration tolerance, tolerance there are individual differences.So the disease can occur in contact with vibration 6 ~ After 9 months, but as early as 1 month and late to several decades later, some contact
