Abstract

The Musculoskeletal disorders lead to disabilities in places of work. The statistics by the government show that these disorders were responsible for a quarter of benefits from incapacity claims in the United Kingdom. This high occurrence of MSD has been confirmed with published research. For example, random survey that was carried out in large scale in 1995, show that MSD was accountable for 57 percent of reports of illnesses that are work related. Likewise, analysis of data by some researchers in Netherlands showed a 27% report of back pains, 8% problems of chronic back and 24% joint and muscle complains (Bongers et al., 2002). The task performed by environmental and personal factors that are related to MSD, in particular pain at the lower back, have been studied in medicine, psychology, and epidemiology. Demographic variables, physical demands, and psychological conditions importance have been involved. Example of recent prospective lessons shows typical findings.

From the findings it was concluded that psychological, organizational, social factors and mechanical exposures are associated to increased cases of back pain. Similarly, work related psychosocial and physical factors affected both the recurrence and incidence of this pain. Particularly, demand of high work, low control and manual handling, were related to back pain recurrence. A new start of paining backs was found predictable merely by y combining psychosocial and physical work factors inclusive of pulling weights, kneeling, monotonous and stressful and hot conditions of work.

[...] Missing control in duties the work dissatisfaction indicates Positive relation with the upper limits MSDs even though this data may not be supportive. Evidence in the connection between upper limits and the psychological factors looks stronger in the neck or shoulder abnormalities or even to the musculoskeletal signs than for hand or wrist disorders. There are a number of reasons for the relationship of the neck/shoulder disorders. These are: the big number of research carried out in Nordic countries. The studies have dealt more on neck/shoulder health outcome as compared to that of the hand/wrist; the second reason is that a lot of neck/shoulder research incorporates various psychological factors in their features, which the research on hand /wrist have not exhausted, which is a requirement.

[...] Some research results indicate that the back pain disorders are totally not associated with the dissatisfaction at work. These findings however are limited in that they depended on the mailed questionnaires used in the survey as much as workplace factors (biochemical) were not exactly measured too.

[...] Another ULD risk factor are due application of force to the extremes which can either be static or repetitive. However, if the risk influences of these factors that are in these tasks are compared with some other working group that is not exposed to the risk factors tend modest in characteristics (Bartys, 2004). MSDs and work place conditions relationship is difficult to establish because the exposure levels some times are just impossible to measure and definitions that are not clear exist for light and heavy work.

[...] In the second section, back disorders are studied. Relationships that are reported under this review are substantial in almost all cases. Odd ratios have been reported where possible. In the interpretation of these studies, it is vital to be equipped with awareness. Generally, there have not been use of standardize methods of psychosocial assessment in relating to MSDs. Above that as much as psychosocial factors related to work are composed of many investigators that are similar, measurement may be done using different ways and variety of scales can be employed that differ in psychometric quality.
