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.

Biomechanics of Occupational Shoulder Injuries, Final Performance Report.

PB2004104285

Publication Date	2004
Personal Author	Karduna, A.; Gracely, E.
Page Count	22
Abstract	The first aim of this proposal was to determine if low load repetitive arm motion would lead to altered scapular motion patterns, thus providing a biomechanical basis for NIOSH's recent report. Since it would have been impractical to implement this type of protocol in an actual work environment to assess muscle impairments, the second aim of This proposal was to identify an index of muscle fatigue that will explain altered motion patterns with repetitive motion. It was believed that this would provide a basis for the development of a screening tool to assess impairment, analogous to that currently being investigated for the low back.
