. The crosssectional studies of active workers and population based studies are sound enough to say that there is not a significant relationship between B6 levels and carpal tunnel syndrome.

If a causal relationship between obesity and a slowing of median conduction across the wrist exists, it may relate to increased fatty tissue within the carpal canal or to increased hydrostatic pressure throughout the carpal canal in obese individuals compared to normal or slender individuals. The median nerve at the wrist is more compartmentalized than the ulnar, peroneal or sural nerves and may be subjected to compression due to fatty build up within the carpal canal among obese individuals.

number of studies that explore the relationship between specific genetic markers and the incidence of CTDs. it is clear that genetics plays a role in the risks associated with gender, obesity, carpal canal size and several connective tissue disorders, but an art from these relationships, the role of genetics in the etiology of CTDs is not well established.

In the main, the findings are drawn from multivariate analyses that controlled for selected physical job demands and workers' personal characteristics. To summarize the results from these studies, non-biomechanical work-related predictors were first placed into six categories based on the name of the factor.

out of nine that investigated job control or related factors found significant associations with musculoskeletal outcomes. The sixth and seventh studies found significant associations for control specifically over temporal aspects of the job, but no associations for general job control or influence (Bergqvist et al.

Overall, where there were significant associations between the six categories of work factors and musculoskeletal outcomes, they typically indicates! modest to moderate increases in risk for the worker with a poorer work environment.

Furthermore, occupational health literature focusing on work stress and general health conditions suggests other risk factors that may be associated with musculoskeletal disorders. The work system paradigm offered by Smith and Carayon (1996)

In terms of the broader category of musculoskeletal disorders, non-biomechanical occupational factors appear to have significant associations with health outcomes, even after controlling for personal factors and biomechanical work factors. Although the time to produce this report was limited, it is doubtful that these overall concussions would have differed in a more extensive review.
