静态工作（焊接在船厂）进行了研究，定量肌电图[EMG]。将有经验和无经验的焊工进行的高空焊接与不太艰苦的工作情况进行了比较。肩部肌肉的肌电图记录在磁带上。肌电频谱的发展表明，本地化的肌肉疲劳是常见的，在长时间的架空工作在没有经验的组，而有经验的焊工表现出疲劳的迹象，在冈上肌肌肉。随后的几个焊接电极在头顶上熔化，导致肌肉反应逐渐增加，这在有经验的工人中也可以看到。
Static work (welding at a ship-yard) was studied by quantitative electromyography [EMG]. Overhead welding by experienced and inexperienced welders was compared to less arduous working situations. EMG from shoulder muscles was recorded on tape. The myoelectric spectral developments indicated that localized muscle fatigue was common in prolonged overhead work in the inexperienced group, whereas experienced welders showed signs of fatigue in the supraspinatus muscle only. Melting of several subsequent welding electrodes overhead entailed a progressive increased in muscular reaction, also seen in experienced workers.
