Musculoskeletal Disorders

Musculoskeletal disorders were recognized as being based etiological factors and occupational. However, only since the 1970s is that occupational factors were studied using epidemiological methods, and studies that linked the work with these factors began to appear regularly in international scientific literature. Since then, the evidence resulting from the development of more than six thousand scientific articles published only address the importance of ergonomics in the workplace. However, the relationship between the musculoskeletal disorders work-related and other factors, it remains a matter of debate. The same kind of controversy has been the subject of study under other conditions, including cancer and lung problems, both with multifactorial causes. musculoskeletal symptoms may still arise or be exacerbated if the work involves exposure to low temperatures. Some authors found a high prevalence of musculoskeletal symptoms workers in areas of very cold (2°C), especially in the lower back, neck and shoulders. Other authors state that the cold reduced muscle performance, leading progressively to a voltage increase fatigue and subsequent premature. Moreover, the psychosocial burden that the worker is subject, plus a weak social support and low job satisfaction develop a mechanism that stress leads to increased muscle tone and activation of pain receivers, enhancing musculoskeletal pain.
