Intrepid Dynamic Exoskeletal Orthoses IDEO and Running-Specific Prostheses RSPs have been designed to allow people with lower extremity limb salvage LS and transtibial amputations TTA to more effectively run, an activity used to improve fitness and health, and to assess physical endurance in military populations. Exercise such as running is extremely important for and strongly associated with quality of life. Moreover, compared to us e of conventional orthoses and prostheses, use of IDEOs and RSPs has resulted in significantly higher functional ability and quality of life for service members with LS and TTA. However, existing practices use a trial-and-error approach for prescription based on a male cohort and do not necessarily optimize performance and satisfaction for women service m embers. Our goals are to determine the optimal IDEO and RSP components and develop quantitative guidelines for prescribing orthoses and prostheses for running in women service m embers with LS and TTA so that these women can regain the greatest possible level of functional ability and return to an active lifestyle andor active duty. The purpose of this study is to determine the physiological and biomechanical effects of using different IDEO and RSP stiffness and weight in women service members with LS or TTA, which will maximize recovery, restore function, and improve quality of life for women with LS or TTA. The specific goals of this project are 1.Verify inter- and intra-session reliability of the Naval Medical Center San Diego Gait AnalysisBiomechanics Laboratory and VA Applied Biomechanics Lab. 2. Quantify metabolic rates, biomechanics, and satisfaction of running in 10 females with unilateral LS using IDEOs with different stiffness and weight. 3. Quantify metabolic rates, biomechanics, and satisfaction of running in 10 females with unilateral TTA using RSPs with different stiffness and weight. 4. Based on Specific Aims 2 and 3, we will disseminate evidence-
