Pre-Existing Conditions And Psychosocial Factors; Vary Your Workday - NEC Generation N3000 M760s User Manual

The Three Stages of Repetitive Strain Injury
Real RSI-pain implies that the problems persist for a longer period of time, normally for a minimum of
three months. The development can be divided into three stages:
•
Stiffness, numbness, irritation, sometimes in combination with light or sharp pains. These problems
disappear, but return when similar work is done.
•
The problems do not disappear overnight. Continuous light pain, also after a period of rest. After a
longer period of rest (holidays) the pain does go away, but returns easily when similar work is done.
•
Continuous pain often combined with reduced strength and less accurate control. At work, the pain
intensifies. When rested, the pain remains.

Pre-Existing Conditions and Psychosocial Factors

Pre-existing conditions that may cause or make some people more susceptible to musculoskeletal
disorders include the following: hereditary factors, vascular disorders, obesity, nutritional deficiencies
(e.g., Vitamin B deficiency), endocrine disorders (e.g., diabetes), hormonal imbalances, connective tissue
disorders (e.g., arthritis), prior trauma (to the hands, wrists, arms, shoulders, neck, back, or legs), prior
musculoskeletal disorders, aging, fluid retention due to pregnancy, poor physical conditioning, dietary
habits and other conditions.
Psychosocial factors associated with these disorders include: workplace stress, poor job satisfaction, lack
of support by management and/or lack of control over one's work.
