A case-referent study was carried out among meatcutters, sausage makers, and packers in a large meat-processing plant to investigate the association between psychomotor capacity and occurrence of tenosynovitis. Reaction time, movement time, manual dexterity, visual attention and visuospatial ability were measured in 26 cases with a history of two or more episodes of tenosynovitis and 26 referents of similar gender, occupation, age, and job seniority with no episodes of the disease. No differences were found between the cases and the referents in any of the tests of psychomotor capacity. The results suggest that psychomotor capacity, as measured with the tests of this study, is a poor predictor of wrist tenosynovitis.
