National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Occupational Risk Factors: Cumulative Trauma Disorders of the Hand and Wrist.

PB87164380

Publication Date	1985
Personal Author	Armstrong, T. J.; Fine, L. J.; Silverstein, B. A.
Page Count	218
Abstract	Possible associations were sought between cumulative trauma disorders (CTDs) and jobs which require highly repetitive or highly forceful hand and wrist motions, irrespective of other factors. Efforts were made to develop field instruments to identify occupationally related upper extremity cumulative trauma disorders in active workers; to estimate the prevalence of upper extremity CTDs among workers in jobs needing force and repetitiveness; to estimate individual and multiplicative contributions of occupational and nonoccupational factors which may be associated with these disorders; and to test the null hypothesis of no association between the prevalence of CTDs among workers with different force and repetitive work requirements. Hand wrist CTDs were strongly associated with high force/high repetitive work and to a lesser extent with high repetitiveness or high force alone. The findings suggest that primary prevention can be accomplished through job modification and reductions in force, repetitive and postural stresses.
