In a group of 429 glass cutters complaints in the region of the ulnar nerve were reported in 44.7%, the local findings in 36.8%. Most complaints in men were reported between the eleventh and twentieth year of glass cutting, in women during the first five years of occupation. Electromyographic studies showed in 24.0% the limit of the normal, in 14.0% discrete pathological findings. The fewest subjective complaints were reported in workers, who had leaned on their forearms instead of their elbows and had been using a rubber rest. In a group of 40 glass cutters a lot of clinical examinations and epidemiological parameters was evaluated. It was found that the upper limits of vibrations transferred to the arms were exceeded. X-ray-examinations of the cervical spine showed pathological findings in 39 of 40 glass cutters. Electromyographic studies revealed disturbances of the ulnar nerve and the median nerve, too. Clinical findings in a group of 422 apprentice glass grinders were discrete but increased year by year. Most clinical findings were seen either during the fourth or during the seventh respectively eighth year of glass cutting.
在一组429名玻璃切割工中，44.7%的人报告有尺神经区域的不适，36.8%有局部症状。男性的大多数不适报告出现在从事玻璃切割工作的第11年至第20年之间，女性则出现在工作的前5年。肌电图研究显示，24.0%处于正常范围，14.0%有轻微病理表现。主观不适最少的是那些靠前臂而非肘部支撑且使用橡胶垫的工人。在一组40名玻璃切割工中，评估了许多临床检查和流行病学参数。发现传递到手臂的振动上限超标。40名玻璃切割工的颈椎X线检查显示39人有病理表现。肌电图研究也揭示了尺神经和正中神经的紊乱。一组422名学徒玻璃研磨工的临床症状不明显，但逐年增加。大多数临床症状分别出现在玻璃切割工作的第4年或第7年及第8年。
