The present labour motor activity is characterized by local loading with constant increase of the static muscular tension. The static work is the cause of reduction of capacity for work, of early advancing fatigue and various occupational diseases of the locomotory system in case of long-lasting activity. With the purpose if studying the connection between the occupational diseases of the locomotory apparatus (LMA) and the characteristics of the labour motor activity--a study on the diseases of the LMA was carried out at the Neurological Department of the Clinic of Occupational Diseases, looking for the correlation between them and the labour physiological data about the severity and tension of the motor activity and some parameters of working movements. The following main characteristics of the motor activity are indicated as risk factors of the occupational diseases--number of movements per a working shift, their velocity and duration, movements needing strength and movements with a big volume, pronounced motor monotony. The correlation between the occupational diseases of LMA, age, sex, length of service, etc. are stressed on. The problem of the optimization pf motor labour activity is discussed as a basic element of prophylaxis of overstrain and occupational diseases of the locomotory system.
当前的劳动运动活动的特点是局部负荷，同时静态肌肉张力持续增加。静态工作是导致工作能力下降、过早疲劳以及在长期活动情况下引发运动系统各种职业病的原因。为了研究运动器官职业病（LMA）与劳动运动活动特征之间的联系，在职业病诊所的神经科对LMA疾病进行了一项研究，寻找它们与劳动生理数据之间的相关性，这些数据涉及运动活动的强度和紧张程度以及工作动作的一些参数。运动活动的以下主要特征被指出是职业病的风险因素——每个工作班次的动作数量、动作速度和持续时间、需要力量的动作和大量动作、明显的运动单调性。强调了LMA职业病与年龄、性别、服务年限等之间的相关性。作为预防运动系统过度劳损和职业病的基本要素，讨论了优化运动劳动活动的问题。
