Title 1st place, PREMUS best paper competition: Workplace and individual factors in wrist tendinosis among blue-collar workers -The San Francisco study
Bibliographic information Mar. 2011, Vol.37, No.2, p.85-98. Illus. 23 ref.
Abstract This study reports findings from a prospective study of right wrist tendinosis among blue-collar workers. It involved 413 workers in four industries, who were followed for 28 months with questionnaires and physical examinations every four months to identify incident cases of right wrist tendinosis. Exposure assessment of force and repetition were based on field measurements and video analysis to determine repetition rate and the percent time in heavy pinch or power grip. All exposure variables were measured at the level of the individual and task. For workers responsible for more than one task, a time-weighted average exposure was calculated based on task hours per week. A proportional hazards model was used to assess the relationship between exposures and incidence of wrist tendinosis. During the 481 person-years of follow-up, there were 26 incident cases of right wrist tendinosis. Adjusting for age, gender and repetition, wrist tendinoses were associated with percent time spent in heavy pinch tasks. An exposure-response relationship was observed for the percent time spent in heavy pinch. The percent time spent in power grip was not a significant predictor, nor were any measures of repetition.
