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 effort is to develop a shoulder injury risk and assessment tool based on shoulder joint injury criteria and task motion that incorporates an anatomically-specific shoulder joint complex into the existing CFDRC Human Model to build and demonstrate a proof of concept exposure model. Typical use cases will be developed and the integrated model will be exercised through these use case scenarios of activity load and exposure schedule. The model will be further developed into a user tool. The user tool will be exercised to develop a hazard risk assessment based on the modeled hazard severity, hazard probability, and AR 40-10 for simple vertical overhead push.
