[Electromyography of the neuromuscular fatigue caused by posture of drivers of the loading machines].

The authors studied strain degree and fatigue severity in long-standing inconvenient postures at work of automobile loader operators. Those workers perform tasks in various postures due to the design of automobile loaders. Compared to standardized postures, long-standing inconvenient ones of automobile loader operators, characterized by left turn of corpse, appear to result in marked overstrain and significant fatigue of neuromuscular apparatus. If specific prophylaxis is absent, the work in such postures could induce considerable fatigue.
