What is “Total Force Fitness”?

Do you know what “Total Force Fitness” is? It’s a Department of Defense model for building and maintaining health, wellness, and resilience.

Have you heard of Total Force Fitness, but you aren’t sure what it is? It’s a framework for building and maintaining health, readiness, and performance in the Department of Defense. It views health, wellness, and resilience as a holistic concept that recognizes “total fitness” as a “state in which the individual, family and organization can sustain optimal well-being and performance under all conditions”—a connection between mind, body, spirit, and family/social relationships. Total fitness shifts the perspective from treatment to wellness and focuses on prevention and strengths.

The Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury created a slide presentation for units and groups on Total Force Fitness: A Brief Overview that describes what TFF is, its core components, and each of its eight “domains” (behavioral, social, physical, environmental, medical and dental, spiritual, nutritional, and psychological). For more in-depth reading, check out the original Military Medicine Supplement that started it all, including a scholarly chapter for each domain.

Antibacterial soaps – beneficial or not?

The U.S. Food and Drug Administration (FDA) plans to revise their guidelines for the use and production of antibacterial soaps

The word “antibacterial” is all too familiar to 21st-century consumers. Soaps and cleaning products that tout “antibacterial” or “kills germs” in large print seem to be everywhere. So it may surprise you to learn that recent studies suggest the use of antibacterial soaps may not be as beneficial as once thought. Research now shows that overuse of these soaps contributes to antibiotic resistance, which makes bacteria stronger and less responsive to antibiotic treatment—a potentially major problem in combat zones and hospitals. In addition, recent animal studies have shown that triclosan, the most common active ingredient in antibacterial soaps, may alter the way hormones work in the body. While these soaps are sometimes necessary in hospital settings, scientists caution against using them in our everyday lives.

FDA will now require that over-the-counter antibacterial soaps must prove that their benefit to a consumer’s health is greater than the current risk for harm to the user and the environment. Manufacturers of over-the-counter antibacterial soaps will be given until December 16, 2014, to provide this evidence or FDA will ban their products.

The ban will not affect hand sanitizers and soaps used in hospital settings. To learn more about the proposed ban of antibacterial soaps, read the FDA consumer update.

A holistic approach to performance

Check out the customizable “One Shot One Kill” (OSOK) performance enhancement program to jumpstart your performance.

Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.

There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.

Sub terra firma

Combat training is moving underground. New tactics—and, potentially, new doctrine—are being developed to help troops perform in underground environments where enemies could hide.

The U.S. Army’s Asymmetric Warfare Group has been training joint forces in some unusual places—underground venues such as tunnels, caves, and sewers. As battlefields become more urban and enemies move underground, subterranean environments pose unique operational challenges. Although the Army does not currently have an official field manual for underground combat, this new tactical training has developed units’ ability to perform in these environments. Combat training centers are starting to integrate these kinds of complex environments into their facilities, and the Army is urging home-station training to “get creative” and use simple techniques to simulate their own underground environments. Something as simple as training in a dark room with obstacles can simulate underground areas. Israeli Defense Forces have also had success with this type of training. Being able to adapt and perform in challenging environments is a vital part of warrior resilience.

One small step for man, one giant leap for lower-limb amputees

Thought-controlled bionic technology previously only available for arms now exists for legs. The once-farfetched idea of a bionic man is becoming a reality.

In 2013, the Research Institute of Chicago (RIC) presented the first mind-controlled bionic leg, thanks to support from the U.S. Army Medical Research and Material Command's (USAMRMC) Telemedicine and Advanced Technology Research Center (TATRC). Until now, this technology was only available for prosthetic arms. These brainy bionic legs are still being studied and perfected, but it’s hoped that they will be available in the next few years. This life-changing technology will be able to help the more than 1,600 service members who have returned from Iraq and Afghanistan with amputations. Bionic limbs will make the transition to active duty or civilian life smoother for wounded warriors.

In one case study, a civilian who lost his lower leg in a motorcycle accident underwent a procedure called “Targeted Muscle Re-innervation”. This procedure redirects nerves that originally went to muscles in the amputated limb to still-healthy muscles in the limb above the amputation. As these healthy muscles contract, they generate signals that are detected by sensors within the prosthetic and analyzed by a specially-designed computer chip and program The program rapidly decodes the type of movement the individual is preparing to do, such as bending the knee, and then sends those commands to the leg. This allows the person to walk up and down ramps and stairs and transition between activities without stopping. The user also can move (reposition) the bionic leg just by thinking about it, which is not possible with current motorized prosthetics.

The bionic leg is also showing a decreased rate of falling and quicker response time. Stay tuned for availability of this groundbreaking technology.

Water pollution and birth defects

HPRC Fitness Arena: Environment, Total Force Fitness
New study from Centers for Disease Control link previously contaminated water to birth defects.

The U.S. Centers for Disease Control (CDC) confirmed what has been suspected for a long time: Previously contaminated tap water at U.S. Marine Corps Base Camp Lejeune was linked to serious birth defects in babies born between 1968 and 1985.

Pregnant women on base were drinking tap water primarily contaminated by chemicals from an off-base dry-cleaning facility. Other chemicals from underground storage tanks, industrial spills, and waste-disposal sites were also detected in the water.

The water wells on base were shut down in 1985, but the damage had already been done. Pregnant women at Camp Lejuene were four times more likely to have babies with serious birth defects (such as spina bifida) as well as a slightly higher risk of developing childhood cancers.

The Veterans Administration continues to provide compensation for those affected by this exposure.

New year, new coveralls for the Navy

By early 2014, more sailors will be better protected against fires with new flame-resistant coveralls.

Before 2013 comes to a close, the Navy will begin distributing Flame Resistant Variant (FRV) coveralls to all Sailors assigned to surface ships and aircraft carriers. Previously, only Sailors working in engineering departments, on flight decks, and in other high-risk areas were issued flame-resistant clothing. However, a recent review found that the highest risk of severe injury from flames was from major fires or explosions, which puts any Sailor at risk. Tests revealed that the Navy Working Uniforms (NWU) type I, made of a polyester cotton blend, are susceptible to melting in a fire, which could cause even greater injury to the wearer. The new FRV coveralls are 100% cotton with a fire-resistant coating, which is self-extinguishing. The Navy plans to improve and standardize all coveralls over the next couple years by combining the protective effects of flame resistance, arc-flash protection, and low-lint specifications into one safe and effective uniform.

Listen up!

Filed under: Hearing, Hearing loss
Hearing loss is a silent epidemic in the military, but it isn’t inevitable. When not around firearm explosions or helicopter noise, follow safe listening practices to help prevent hearing loss.

Veterans who served in the U.S. and abroad between September 2001 and March 2010 were four times more likely than civilians to suffer from severe hearing loss. In fact, two of the most common disabilities affecting service members today are hearing loss and tinnitus, says the Hearing Center of Excellence (HCoE). Hearing loss and tinnitus seriously impact force readiness as well as the emotional and social well-being of those affected.

However, not all hearing loss results from the noise pollution Warfighters experience in the field. Many everyday exposures, such as your MP3 player or loud music in your car, can be just as damaging as firearms or helicopters. To maintain good hearing and operational readiness, Warfighters must use safe listening practices at all times. HCoE recommends these safe listening practices:

  • Never listen to your MP3 player at maximum volume.
  • Following the “60:60” rule: 60 percent maximum volume on your MP3 player for no more than 60 minutes a day.
  • Take periodic breaks of 15–20 minutes when listening to loud music to allow your ears to recover.
  • Select headphones or earbuds designed to remove background noise.
  • Exercise caution when listening to music in the car. Listening in a confined space increases the risk of hearing damage.
  • Wear hearing-protection devices such as earplugs at concerts, sporting events, parades, and other high-noise situations.

For more information on how to protect your hearing, as well as treatment and rehabilitation for hearing loss, please read this article from HPRC and visit HCoE.

Regaining a sense of touch

Filed under: Prosthetic limbs
Prosthetic arms are becoming more sophisticated—improving the quality of life for individuals with missing upper limbs. The only thing lacking is a sense of touch, but perhaps not for long.

Prosthetic limbs have come a long way in a short amount of time, mostly because of the number of service members coming back from deployments with traumatic injuries and with the demand for better technology. Advancements in prosthetic arms now include devices that can move and bend individual fingers and joints. However, a sense of touch is one remaining obstacle—but one that researchers are close to conquering.

Many patients with arm prosthetics describe the difficulty with grabbing objects because there is no feedback to the brain. For example, breaking dishes, bruising fruit by grabbing it too hard, and dropping slippery cans are all too likely without any sense of feeling in the hand.

Researchers are now developing a prosthetic limb—called the Modular Prosthetic Limb—that will close the loop between the brain and the prosthetic hand by adding various sensors to contact points such as the fingertips and joints. This will allow sensory feedback to the brain that gives the user enough “feeling” to distinguish between a wool sweater and a cold beverage, for example.

The Department of Defense is working with various universities such as Johns Hopkins and the University of Pittsburgh to develop this unique device and make it available to wounded warriors.
