Shoulder injury risk and exertion assessment tool

Musculoskeletal injury among military personnel is an under-recognized problem where shoulder injuries are significant and result in inflammation and pain from overuse, joint derangement, sprain/stain/rupture, and dislocation. Health hazard assessment is essential to ensure that fielded equipment and occupational duties do not exceed human capabilities over short and long term exposures. Hazard assessment encompasses determination of the hazard severity and hazard probability. This effort is based on the desire to enhance health hazard assessment through the development of methodologies using injury criteria that can translate into hazard severity and probability. The purpose of this Phase II effort is to develop a software shoulder injury risk and assessment tool based on the Phase I developed shoulder injury criteria and integrated anatomically-specific shoulder joint complex. The tool will be validated for one and two handed push and pull using human subjects. The user tool will be exercised to develop design standards for one and two handed push and pull motions based on the modeled hazard severity and hazard probability reflected in AR 40-10.
