已知长期振动作用引起机体不同生理系统活动的障碍,是青壮年工人劳动力降低的原因之一,本文研究振动病晚期患者的生物电活动,大脑血液动力学,以及神经—肌肉系统的机能。采用脑电图、脑血流图和肌电图检查97例(男55,女42),大多数患者是钢筋水泥联合企业的混凝土工和造型工,30～40％的劳 It is known that long-term vibration causes obstacles to the activities of different physiological systems. This is one of the reasons for the decrease of labor force among young adults. In this paper, bioelectrical activities, cerebral hemodynamics, and neuromuscular system functions in patients with late vibration sickness were studied. Ninety-seven cases (male 55, female 42) were examined by EEG, cerebral blood flow and electromyography. Most of the patients were concrete workers and molders in steel-reinforced concrete joint ventures and 30 to 40% of workers
