Safe moving tips to spare your back

Here’s a reminder about how to lift heavy objects properly and protect your back when loading your moving truck during a PCS.

Many Warfighters relocate a lot, and moving to a new home is hard enough without the added stress of an injury. Here are some tips on how to properly lift and push/pull heavy objects such as moving boxes and furniture, and how to take care of yourself if you do sustain an injury:

  • Wear less-restrictive clothing such as looser-fitting pants or workout clothes.
  • Wear closed-toed shoes.
  • Take breaks when necessary. Stretching and reassessing your mechanics can help you maintain proper posture when lifting. HPRC has tips on how to maintain flexibility and remove tension in your body.
  • The U.S. Army has some additional Lifting Techniques for handling heavy objects.
  • Remember to keep your core tight and use your leg muscles rather than your back to lift heavy objects.

The best way to prevent back injury is to strengthen your back and core muscles. The National Institutes of Health (NIH) has suggestions and exercises to help build your back.

If you’re sore from all the lifting or think you may have pulled something, you can treat the pain with ice and rest—and perhaps an over-the-counter pain reliever—for the first 48 hours. Follow the NIH guidelines on how to further treat your back pain if it’s acute. However, if the pain persists, consult your doctor to rule out a more serious back problem or injury before you do any more heavy lifting. If all seems well, consider core-strengthening exercises to support your back. Taking a yoga class to relieve your pain, build your muscles, and return your back to normal function is a good option. In a recent large study of adults with chronic low back pain, those who participated in yoga classes saw reduced pain symptoms and improved mobility that lasted for several months.

The best routines are…not routine?

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Routines help athletes and Warfighters achieve their best, but rigid routines can get in the way. Flexibility and adaptation are keys to success.

Routines often help performance, and some of the world’s best athletes have scripted routines that begin with what time they wake up. This type of rigid approach can be useful when the environment is predictable. Top performers find that routines can help shift them from the stressful anticipation of how things are going to turn out to a focus on what’s most important in that moment; in other words, routines can provide an escape from anxiety. But overly rigid routines can morph a helpful tool into a superstitious or obsessive ritual. The best athletes regard flexibility and adaptation as crucial to their own, often finely honed, routines. With Warfighters, for whom crises are part of the job, the best teams are able to go “off-script” when needed in order to work together most effectively.

Adjusting to work relationships after deployment

Deployment stress can sometimes hang around and impact work relationships after you are back home. Learn more about common issues and tips to deal with them.

The stress of deployment can linger when you return home and resume (or start new) work responsibilities and relationships. Sometimes it can be difficult to know how much to share about recent deployment experiences in the work environment, particularly if your coworkers are not or have not been in the military. Some may ask a lot of questions and others may steer clear of the subject entirely. This can create an interesting dynamic in your work relationships. Afterdeployment.org emphasizes that discussing your experience is a decision that’s completely up to you. So think ahead of time about how much (if any) you want to share, and be cautious about whom you choose to share with initially.

Afterdeployment.org also describes some common problems that can affect performance in the workplace. For example, combat experiences sometimes can impact your sleep quality, making it difficult to be at your peak at work. Other possible issues include inappropriate anger in response to people or situations and feeling uneasy and unable to let one’s guard down in a crowded office or worksite.  This Work Adjustment factsheet provides more information and tips that can help with common issues, and another on Informal Relationships at work for more information.

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.

Got lactose (intolerance)?

Lactose intolerance can really put a damper on performance. What is it and what are some tips to handle this condition?

Do milk products make you queasy, gassy, or—worse—send you running to the bathroom? If so, you might have lactose intolerance, a condition caused by a deficiency of lactase, an enzyme produced in the small intestine. Lactase breaks down lactose, a naturally occurring sugar present in milk and milk products.

Symptoms of lactose intolerance include nausea, gas, cramping, and diarrhea and usually occur 30 minutes to two hours after eating milk products. Anyone (at any age) can develop lactose intolerance, but it’s more common among adults of African, American Indian, Asian, Jewish, or Mexican heritage. People who have digestive diseases such as Crohn’s disease, ulcerative colitis, or celiac disease are more likely to be lactose intolerant too.

Some people with lactose intolerance have to avoid all milk products, but others can handle small amounts of cultured milk products such as yogurt, kefir, or buttermilk. If you think you have lactose intolerance, experiment with milk products to see what you can handle.

Many processed foods (including MREs) contain milk products, so learn to be label-savvy: Look for words on food packages that indicate a product might have milk or milk products such as whey, curds, milk byproducts, dry milk solids, and nonfat dry milk powder. Missing your ice cream? Over-the-counter enzyme products can help you tolerate lactose-containing foods if taken with the first bite of food.

Don’t confuse lactose intolerance with milk allergy, an immune response to casein or whey, two proteins found in milk. Symptoms of milk allergy are typically mild and include:

  • Runny nose, sneezing, or shortness of breath
  • Swollen lips, tongue, or throat
  • Rash, hives, or itchy skin

However, severe milk allergy can cause anaphylaxis, a serious, life-threatening condition that requires immediate medical attention. People with severe milk allergy should read labels carefully to avoid all milk products.

Of course, limiting or avoiding milk products could put you at greater risk of developing osteoporosis or “brittle bones.” That’s because milk products contain calcium, an essential nutrient for healthy bones. Look for other calcium-rich foods such as dark-green leafy vegetables, almonds, beans, shellfish, or calcium-fortified juices, soymilk, or almond milk.

To learn more about lactose intolerance, read this informative article from the National Digestive Diseases Information Clearinghouse.

See it, feel it, do it!

Mental imagery is no magic trick—it’s an essential training tool. Learn why and pick up some tips on how to make these mind rehearsals as productive as possible.

A popular sport psychology technique Warfighters can use is mental imagery. This is the practice of seeing (and feeling) in your mind’s eye how you want to perform a skill, as if you were actually doing it. It can augment your usual training and help you maintain—or even surpass—your current skill level, even when you’re sidelined.

Some of the ways that imagery helps performance include:

  • —  Better decision-making
  • —  Fewer errors
  • —  Improved attention
  • —  Increased confidence
  • —  Reduced stress and anxiety

You can generate imagery in your mind for just about any task (improving your running time or marksmanship, for example). Good mental imagery incorporates all of the senses, and it often helps to listen to a scripted audio recording. You can create your own and/or work with a CSF Prep Master Resilience Trainer-Performance Expert to develop one.

Watching others can also help. In fact, being a spectator can boost learning even more than mental imagery by itself because you’re viewing what you’d like to accomplish rather than conjuring up images with your own mind. Both methods of learning are effective. Observing can be in-person or by video, but you can also combine video/imagery approaches and potentially get even more bang for your buck.

With either approach, or with the combined approach, it is important to “feel” yourself executing the skill, even though you might be sitting or lying down. Of course, imagery doesn’t have to be done while you’re sitting still. Try using imagery in the setting where you’ll actually perform the skill. You can even incorporate it into existing training protocols.

Watch HPRC for future posts where we’ll explain how to create your own imagery. Until then, check out other mental performance skills located in Mind Tactics.

Building family resilience

Further strengthen your family’s resilience with this new resource that discusses how to build it during and following deployment.

Building family resilience is a process that lasts a lifetime, but it can be immensely rewarding. But what is resilience and how can military families in particular build it? HPRC has a resource called “Building Family Resilience” that can give you answers to these questions. The article covers military-specific stressors for families—including how deployment and reintegration impact family relationships, war-related physical and mental health conditions, and individual stress responses and risky behaviors in family members, both adults and children. It also highlights three key resilience-building skills—mind-body, cognitive-behavioral, and communication—and highlights resources to build resilience. Check it out.

For more information on building family resilience, check out the Family Resilience section of HPRC’s website.

What’s the big IDEO?

The Intrepid Dynamic Exoskeletal Orthosis (IDEO), a new orthotic technology designed for limb-salvage patients, helps Warfighters return to running, sports, and combat.

The U.S. Army has developed a device that will not only reduce the number of amputations but will help severely injured Warfighters return to duty. In the past, Warfighters with crushed and battered legs faced amputation or, at best, dysfunction due to pain and weakness. Now, with the introduction of the U.S. Army’s newest orthotic technology, amputations and decreased mobility may be a thing of the past for some.

The Intrepid Dynamic Exoskeletal Orthosis (IDEO) is the latest orthotic technology designed for Warfighters whose legs were crushed in combat. It uses technology similar to that of prosthetics worn by amputees and is higher in user satisfaction and performance compared with other braces available. Unlike other braces, IDEO does not depend on ankle movement, so Warfighters with fused ankle bones, where function is limited, can use them with little pain. With each step, IDEO stores energy and transfers it to the back of the brace, which springs the leg forward (similar to running-blade prosthetics). This allows the wearer to continue rebuilding the muscles in his or her leg while also working on functional movement.

In a study conducted by the Center for the Intrepid, eight of ten patients fitted with IDEO were able to run at least two miles without stopping. All ten Warfighters returned to weightlifting, many returned to playing sports or participating in mini-triathlons, and three returned to combat—two with Special Forces and one Army Ranger. The published report emphasized that the success of these patients was due not only to the innovative IDEO but also to the intense rehabilitation program and—most important—the motivation and drive of the individuals.

In combination with rehabilitation programs, IDEO looks like the newest in a wave of innovations that will help Warfighters return to normal function. If you are interested in learning more about IDEO and other innovative rehabilitation programs, please visit the U.S. Army Institute for Surgical Research and the Brooke Army Medical Center’s Center for the Intrepid.
