National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	The goal of this project was to develop and validate a method for testing the biomechanical risk factors for occupational hand injury due to overuse. This project focused on the risk factors of force and frequency in order to determine how hard and fast a worker can perform a repeating hand task without injury. This is an important problem for the United States workforce because manual handling and similar tasks are on the rise along with upper musculoskeletal disorders. Even some jobs considered white collar such as dental hygiene are seeing increasing hand injuries which may be due to forceful and repetitive hand tasks like periodontal scaling. The design approach of this project was to measure the biological changes in finger joint tissues following repeated grip-like motions with groups of experiments testing different force levels and different frequency levels. Because measuring biological effects of joint tissues requires destructive methods (biochemistry, histology, etc.), it was necessary to first create an animal model for cyclical finger joint loading. Thus, the first aim of the project was to create an in vivo model that would simulate hand tasks using occupationally relevant loads and speeds. The second and third aims of the project were to measure the structural and biochemical changes resulting from the loading and to determine if these changes are co-localized. The fourth aim of the project was to test different force levels and different frequency levels to determine if thresholds of loading exist.
