局部振动对人体的影响。早期以神经系统的改变为主,往往以末梢神经炎的形态出现。调查证明,肢端麻木和感觉异常的主诉较多,尤其手麻、手痛、手冷感、手无力等局部症状出现较早,并且与振动性白指共同成为局部振动病的主要症候群。因此,末梢神经机能(指端感觉)检查的研究有重要意义。本文报道,用定量方法对振动性白指患者、局部振动接触者和对照组工人进行痛觉、振动觉、两点分辨觉、深度觉检查,并且进行冷水负荷试验前后的比较分析,以 Local vibration on the human body. Early changes in the nervous system, often appear in the form of peripheral neuritis. Surveys have shown that there are more main complaints of numbness and sensory abnormalities in the extremities. In particular, local symptoms such as hand anesthesia, hand pain, hand cold sensation and hand weakness appear earlier and become the main syndromes of local vibration diseases together with white vibrating fingers. Therefore, the study of peripheral nerve function (fingertip sensation) is of great significance. In this paper, quantitative methods were used to evaluate the pain sensation, vibration sensation, two-point sensation and depth sensation in patients with shaky white finger, local vibration contact and control group, and comparative analysis before and after the cold water load test
