Carpal tunnel syndrome (CTS) has been reported as one of the most common injuries experienced by office personnel since most of them have become computer users.
The purpose of this study was to develop a predictive model of the risk of acquiring work-related CTS among office employees.
A total of 100 female employees belonging to the clerical staff at a major Midwestem university were studied.
Data were collected on job exposure, anthropometry and posture factors using self-administered questionnaires, direct observation and video recording.
A discriminant function model with six variables (i.e., task duration, trunk incline, wrist extension, wrist ulnar deviation, overall anthropometric measure, weighted anthropometric measure) correctly classified 73% of the CTS group and 72% of non-CTS group.
Using a six variable logistic regression model, the probabilities associated with changes in the predictive variables as effecting CTS risk may be obtained.
The results of the study also suggest that the main causation of CTS is job design, followed by sitting and wrist postures and the individual's anthropometric make-up.
