RESUMO
The authors demonstrated that work of female molders, acquisitors and stacking packers is characterized by physical load, great number of cliched manual movements, intensive inclinations of corpse and constrained working posture. Prolonged exposure to unfavorable occupational factors results in neuromuscular and cardiovascular stress that induces pathologic changes with increasing length of service. Complex of prophylactic measures suggested by the authors proves effective as releases working strain and delays fatigue during the working shift.

The article presents laboratory results describing influence of hand and arm temperature on capacity of fingers' flexor muscles for dynamic physical work. New means and method for individual protection from local vibration are designed. The authors discuss efficiency of these novelties for exposure of hands to local physical load and vibration.

The examination covered female operators of sewing pickup, engaged into the work at video-displays. The total work load appeared to equal 77.6% and the work at video-display--75.2% of the shift time. Functional state of the vision demonstrated a decrease even after 2 hrs of the work, then stabilized by midpoint of the shift and afterwards lowered by 10-12 hrs of the work. Those objective changes correlated with the sensation of orbital discomfort. The findings served as a base for prophylaxis to restore the performance during the regulated breaks.
