To evaluate neurological symptoms in the vibration syndrome, 55 patients with vascular and neurological symptoms in the hand who had been exposed to vibration were examined. Their exposure to vibration was estimated and neurological vascular symptoms were evaluated according to symptom scales. Temperature thresholds were measured on the right thenar eminence and on the distal volar aspect of the second and third fingers held together on both sides. Vibration thresholds were measured dorsally on the second and fifth metacarpal bones and on the second and fifth fingers proximal to the nail roots. Subjects with advanced neurological symptoms had higher temperature and vibration thresholds than subjects with less advanced symptoms. No such relation was found between vascular symptoms and the outcome of sensory testing. Thus neurological but not vascular symptoms are reflected by the outcome of quantitative sensory testing. In subjects with advanced neurological symptoms the tests gave a high proportion of abnormal results, indicating that these tests may be used for the diagnosis of vibration syndrome on an individual basis. Patients with advanced vascular and neurological symptoms had higher exposure dose scores than patients with less advanced symptoms, indicating a dose response relation between vibration "dose" and neurological and vascular symptoms.
为评估振动综合征中的神经症状，对55名手部有血管和神经症状且接触过振动的患者进行了检查。评估他们的振动接触情况，并根据症状量表对神经血管症状进行评估。在双侧并拢的右手鱼际隆起处以及第二和第三指的远侧掌面测量温度阈值。在第二和第五掌骨背侧以及指甲根部近端的第二和第五指测量振动阈值。神经症状较重的受试者比症状较轻的受试者具有更高的温度和振动阈值。在血管症状与感觉测试结果之间未发现此类关系。因此，定量感觉测试的结果反映的是神经症状而非血管症状。在神经症状较重的受试者中，测试结果异常的比例较高，这表明这些测试可用于个体振动综合征的诊断。血管和神经症状较重的患者比症状较轻的患者具有更高的接触剂量评分，表明振动“剂量”与神经和血管症状之间存在剂量反应关系。
