A MODEL FOR PREDICTION CTDS DUE TO REPETITIVE LOADING

手和手腕的累积创伤障碍(CTD)对于今天的劳动力来说是一个日益严重的问题。这项工作的长期目标是减少工作场所累积创伤障碍的扩散。拟议研究的具体目的是展示和评估一种在工作场所处理四氯化碳的创新方法。拟议的工作重点是展示一种对重复、力量、姿势和工人人体测量敏感的肌腱适应模型。此外，还将对模型性能进行评估，并对模型参数进行灵敏度分析。建议的模型在预防伤害和帮助设计更好的产品方面都具有巨大的潜力。经进一步验证，该模型可用于建立CTDS与工作条件之间的定量关系。最终的结果将是：识别高风险的工作条件，量化问题，提供改变这些条件的合理手段，并验证这些改变确实会降低风险。因此，这种模式将提供早期发现和预防，而不是等到CTD达到衰弱状态。

Cumulative trauma disorders (CTDs) of the hand and wrist are an ever increasing problem for today's workforce. The long-term objective of this work is to decrease the proliferation of cumulative trauma disorders in the workplace. The specific aim of the proposed research is to demonstrate and evaluate an innovative method for dealing with CTDs in the workplace. The proposed effort is focused on the demonstration of a tendon adaptation model that is sensitive to repetition, force, posture and worker anthropometry. In addition, the model performance will be evaluated and sensitivity analysis performed on the model parameters. The proposed model has enormous potential in both preventing injuries and helping to design better products. With further validation the model can be used to establish a quantitative relationship between CTDs and work conditions. The ultimate result will be the ability to: identify high risk work conditions, quantify the problems providing a rational means of altering these conditions, and verify that the changes will indeed reduce the risks. Thus, rather than waiting until CTDs are reaching a debilitating state, this model will provide early detection and prevention.
