As a result of 5-year-long electromyographic observation of 144 persons engaged in ferroalloy production, the parkinsonism syndrome was diagnosed in 4 persons. The disease development was slow, gradual, with the muscular tension growth against the asthenovegetative symptoms. This particularity did not correspond to the traditional view of the three-stage development of chronic manganese intoxication prior to the acute phase of manganese parkinsonism. The contributors hold that the stretch reflex proved to be the most early-stage oriented, prognostically and diagnostically reliable among the other electromyographic techniques.
对144名从事铁合金生产的人员进行了为期5年的肌电图观察，结果在4人身上诊断出帕金森综合征。疾病发展缓慢、渐进，肌肉张力增加并伴有无力性植物神经症状。这种特殊性与锰中毒帕金森症急性期之前慢性锰中毒三阶段发展的传统观点不符。作者认为，在其他肌电图技术中，牵张反射在预后和诊断方面被证明是最具早期指向性且可靠的。
