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.
18名受试者参与了一项初步研究，以确定两种教育方案对有发展为累积性创伤障碍（CTD）风险的产业工人手部使用模式的影响。受试者被分为三组：两组接受不同的教育方案，第三组作为对照组。一个方案仅使用一份讲义作为教育工具；另一个方案除了使用讲义外，还对手册中的概念进行实际演示。对所有受试者进行了工作期间手部和手腕CTD相关动作频率的前测和后测。两个教育方案在减少接受教育1周后测试的工人的危险动作数量方面均具有显著效果。两个教育方案之间未发现显著差异。本研究结果表明，教育可以影响手部使用模式，建议对更大样本进行类似研究。
