The effects of education on hand use with industrial workers in repetitive jobs.

Eighteen subjects participated in a preliminary study to determine the effects of two types of educational programs on the hand-use patterns of industrial workers at risk for developing cumulative trauma disorder (CTD). The subjects were divided into three groups: Two groups received different educational programs and the third group served as the control. One program used a handout as the only educational tool; the other used the handout as well as a hands-on demonstration of the concepts in the handout. Pretests and posttests of the frequency of movements identified with CTD of the hand and wrist during work were administered to all subjects. Both educational programs were significantly effective in reducing the number of at-risk movements performed by workers tested 1 week after receiving the education. No significant difference was found between the two educational programs. The results of this study show that education can affect hand-use patterns, and a similar study on a larger sample is recommended.
