Title Psychophysiology of work: Stress, gender, endocrine response, and work-related upper extremity disorders
Bibliographic information May 2002, Vol.41, No.5, p.383-392. Illus. 98 ref.
Abstract Mental stress may induce muscle tension and has been proposed as a contributing cause of the development of work-related upper extremity disorders (WRUEDs) by driving low-threshold motor units into degenerative processes through overload. Perceived stress, catecholamines, blood pressure and heart rate are associated with stress-induced elevation of trapezius electromyographic activity. In repetitive tasks, where WRUEDs are common, psychophysiological arousal is generally high both during and after work. A possible explanation of the high prevalence of WRUEDs among women could be that women often perform repetitive tasks and are exposed to additional stress from unpaid work. It is concluded that both physical and psychosocial work conditions may contribute to WRUEDs by inducing physiological stress and muscle tension.
