The Predictors of Carpal Tunnel Syndrome Study in Saint Louis
The Predictors of Carpal Tunnel Syndrome (PrediCTS) study is an ongoing prospective study of carpal tunnel syndrome (CTS) in newly hired workers aimed at assessing 1) the usefulness of post-offer pre-placement nerve conduction testing and 2) personal and workplace exposures associated with CTS. Subjects (n=1108) were newly hired workers recruited from three union apprenticeship programs and eight employers in the St. Louis area. Data include physical examination, nerve conduction studies, self-administered questionnaires, and worksite exposure observations; subjects were followed for three years. At baseline, 1.6％ of workers met a clinical case definition of CTS; the rate among construction apprentices was 3.0％. Previous work in hand-intensive industries was an independent risk factor for CTS at baseline. Job physical exposures of the hand and wrist, as well as psychosocial and personal risk factors, predicted symptoms and work disability at 6 months and 18 month follow-ups. Baseline abnormalities of nerve conduction predicted hand symptoms and clinical diagnoses of CTS at 36 months followup. However, this association was not strong enough to warrant the practice of screening of asymptomatic workers. In methodological studies using the PrediCTS data, we examined the reliability of hand diagrams, and agreement between different methods of assessing workplace physical exposures.
