Temporal-spatial symmetry allows for optimal metabolic economy in unimpaired human gait. The gait of individuals with unilateral transfemoral amputation is characterized by temporal-spatial asymmetries and greater metabolic energy expenditure. The objective of this study was to determine whether temporal-spatial asymmetries account for greater metabolic energy expenditure in individuals with unilateral transfemoral amputation. ⋯ There is mixed evidence for the relationship between temporal-spatial asymmetries and metabolic energy expenditure. This preliminary study may suggest optimal metabolic energy expenditure in individuals with transfemoral amputation occurs at an individualized level of symmetry and resultant deviations incur a metabolic penalty. The results of this study support the idea that addressing only temporal-spatial gait asymmetries in individuals with transfemoral amputation through rehabilitation may not improve metabolic economy. Nevertheless, future prospective research is necessary to confirm these results and implications for clinical practice.

Physical activity (PA) has a great influence on bone mineral density (BMD) and bone mineral content (BMC), however longitudinal studies that seek to relate bone mass to physical activity are scarce and have a small sample size. The aim of this study was to evaluate and compare the effect of 7 months of military physical training (MPT), impact sports (IS), and swimming in the bone mass of young military adults. ⋯ After 7 months of training, there were significant increases in BMC and BMD of all the groups evaluated. The bone response was associated with the muscular group used in the physical exercise and the IS group showed greater gain in BMD.

The United States Military Health System provides healthcare to a diverse patient population throughout the world. There are three distinct challenges that the Military Health System faces. (1) Providers have varying degrees of clinical training expertise and may be called upon to practice outside their usual scope of care. (2) There is geographic isolation of patients and providers with limited resources while stationed overseas. (3) Patients are at higher risk of breaks in continuity of care because of permanent change of duty stations, deployments, and retirement. ⋯ Mobile health is a powerful platform which can help deliver standardized care in missions around the world and improve access to care for patients at military treatment facilities in the United States. The United States Military Health System would benefit greatly from creating universal mobile health applications to assist providers in patient access to care, military mission readiness, and disease specific modules. Future resources should be dedicated to the development of a mobile health application pool that is universally implemented across services to improve quality of care delivered at home and in theater by military providers.

Randomized Controlled Trial
Self-Managed Strength Training for Active Duty Military With a Knee Injury: A Randomized Controlled Pilot Trial.
Knee injuries among active duty military are one of the most frequent musculoskeletal injuries and are often caused by exercise or intense physical activity or combat training. These injuries pose a threat to force readiness. Our objective was to assess feasibility (including recruitment and retention rates) of three self-managed strengthening strategies for knee injuries and determine if they resulted in improvements in lower extremity strength, function, pain, and activity compared to usual physical therapy (PT) in military members. ⋯ Knee extensor strength improvements in the COMBO group were significantly higher compared to usual PT. Pain, functional measures, and ADLS all improved during the study with no group differences. Further research is required to confirm these findings.

The identified number of isolated populations with unique medical characteristics is growing. These populations are difficult to study. Civil-military humanitarian operations are part of our medical force readiness training, and are also a venue through which unique populations can be simultaneously served and evaluated. Continuing Promise 2017 was a collaborative effort between the US Navy, non-governmental organizations, and the Colombian Ministry of Health, Navy and Army to provide primary medical care to the Wayuu indigenous people in the La Guajira Department of Colombia. ⋯ This study is the first to document the general health characteristics of the Wayuu people. It demonstrates that in addition to providing important readiness training to our own personnel, humanitarian missions can provide medical care and explore unique, isolated populations. Although retrospective and limited in size, it can be used to shape future medical missions to their region, and will hopefully stimulate formal research into their remarkable characteristics.
