A follow up study of hand/wrist disorders was conducted among investment casting factory workers 3 years after the original 1983 study. Participants were divided into four exposure categories according to hand force requirements and repetitiveness characteristics of their jobs: low force, low repetitive; high force, low repetitive; low force, high repetitive; and high force, high repetitive. The same standardized interview and noninvasive physical examination performed in 1983 were repeated in 1986, and additional questions on job satisfaction were added to the interview. Of the 152 participants in the original study, 136 participated in the follow up; approximately 25 percent had different jobs in 1986. Thirty five percent of participants who had different jobs in 1986 were transferred because of hand/wrist disorders. Eleven percent of workers who had the same job during both surveys, had had temporary job changes due to disorders in the preceding 3 years. Transfer was more frequent for workers with high force and high repetitive jobs. No relationship between ergonomic changes and change in prevalence of chronic hand/wrist disorders was found.
