Advanced Composite Insoles for the Reduction of Stress Fractures
Musculoskeletal injuries of the lower legs, as a result of strenuous and prolonged walking and running activities, are a primary problem for Army soldiers and other military populations. This proposal is focused on demonstrating the feasibility of a patent-pending orthotic device pioneered by Kingetics LLC to reduce injury and enhance ambulatory performance. Utilizing high modulus advanced composites, the orthotic design is based on innovative implementation of the well-known lever-fulcrum spring mechanism. The device efficiently reduces loading rates while increasing energy storage and energy return, thereby decreasing the risk of stress fracture injuries, and is also lightweight and puncture resistant. Whereas a preliminary pre-prototype device has undergone some promising early testing, Phase I efforts will generate a range of systematically varied concept designs, from which two of the most promising will be selected for prototyping under well controlled fabrication conditions. Numerous replicates of the selected prototypes will be manufactured for evaluation of puncture resistance and other mechanical properties. In addition, the Phase I efforts will make predictive assessments of the orthotics effects on human biomechanics, based on input from prototype mechanical data, and will provide quantitative concepts and models for incorporation of the orthotic into a synergistic military boot housing.
