Saxon Switzerland, the Saxon part of the Elbe Sandstone Mountains, is one of the most traditional and challenging climbing regions in Germany and has a strict climbing code. For example, the use of metal safety equipment such as chockstones is strictly prohibited in order to protect the soft rocks. Instead, only runners may be used. The use of chalk is also forbidden. Climbing places a strain on the upper extremities in particular. The majority of acute injuries are to the annular ligaments of the fingers. Strain injuries primarily give rise to symptoms in the flexor tendons and joints of the fingers, as well as tennis and golf elbow and strain in the shoulder area.

Endocat , the local Bauerfeind distributor, opened a showroom in Calle Francisco G. Sada 2925, just a few blocks away from the popular Galerías Monterrey. The store offers our Germanmade supports, braces and compression stockings. “Our showroom is the first one exclusively dedicated to the promotion of Bauerfeind products in Mexico. It creates an environment that helps us to build and position the brand,” says Mauricio Garza, Project Manager, Bauerfeind Shop Monterrey. “The Bauerfeind products are so differentiated from the market supply that doctors, physiotherapists and athletes recognize and appreciate that the products really help them and their † patients to improve their performance and their wellbeing.” Is the support in the right position?

Compression stockings Bauerfeind turns to microfibers Bauerfeind is using microfibers to increase wearing comfort and therefore acceptance of medical compression stockings. With the round-knit Compression Sock Performance, VenoTrain micro and VenoTrain impuls stockings and the flat-knit VenoTrain curaflow, every treatment area can benefit from at least one product with a high microfiber content (between 40 and 50 percent). Whether for sport , preventative use, mild to severe vein problems or lymphological indications, high-quality microfibers mean that the compression stockings are comfortably soft , allow good air circulation and are particularly kind to † the skin. A look at the VenoTrain micro 2014 collection. OmoLoc The OmoLoc uses three arm loops to hold the arm in the 0-degree abduction position, immobilizing the shoulder joint after surgery or dislocation, while allowing the arm to rest at a right angle. To further improve the comfort of this position we repositioned the synthetic buckle, diverting the tensioning strap on the upper arm loop, and added soft velour padding. The buckle is now positioned further towards the outside of your upper arm, preventing it from causing undue strain on your forearm. This will make it easier to tighten the strap, further simplifying putting on and taking off the orthosis. The new soft velour padding underneath the synthetic buckle will also protect your skin from irritation while tightening the strap and during wear. The OmoLoc’s arm loops can be positioned freely along the abdominal strap to suit the patient’s individual anatomy. The open and light construction without a shoulder strap makes main† taining personal hygiene easier, particularly around the wound. 8 life magazine 2014/2 Now even more comfortable: OmoLoc. Pictures: Bauerfeind Re-designed upper arm loop NEWS Award for Dr. Albert-Adrien Ramelet “This is also a fantastic honor for Swiss phlebologists” Dr. med. Dr. h. c. Albert-Adrien Ramelet was awarded the Ratschow Memorial Medal for his life’s work, at the annual conference of the German Society of Phlebology on September 19, 2014. The author of several text books and practicing physician has worked in the field of phlebology and angiology for more than 20 years and has shown great commitment to research, teaching and further training. Award winner Dr. med. Dr. h. c. Albert-Adrien Ramelet (center) with Dr. Hans-Jürgen Thomä (left), Bauerfeind, and Prof. Dr. med. Eberhard Rabe (right) president of the International Union of Phlebology. Swiss-born Dr. Albert-Adrien Ramelet is one of the most renowned specialists in the field of vascular diseases actively practicing today. He has been awarded honorary membership of many national and international specialist associations and has held the position of president or vice-president of many of them. Dr. Ramelet developed a particular interest in vascular diseases and dermatology early on. As soon as he completed his medical studies in Lausanne, he decided to write his thesis on the subject of vascular surgery under the guidance of Prof. Peter Waibel in Basel. His subsequent dermatological training led him beyond Lausanne in Switzerland to Paris and Vienna. “As inhabi tants of a small country with four languages, we Swiss have a fantastic opportunity to be multilingual ,” says Dr. Ramelet , “and we should take advantage of this by traveling abroad frequently to learn more.” In the service of progress and the transfer of knowledge After becoming senior physician of dermatology in Lausanne, Dr. Ramelet introduced the Doppler system there, as well as phlebectomy, a procedure which he previously The Ratschow Memorial Medal Since 1969, the Ratschow Memorial Medal has been awarded by the Curatorium Angiologiae Internationalis to particularly deserving scientists from the field of vascular medicine and closely related disciplines. Bauerfeind AG has been a patron of this foundation for many years. For more information, see www.bauerfeind.com/ratschow. learned under Dr. Robert Muller. He always pursued the same aim – that of establishing medical progress everywhere. He also pushed himself; for example he developed and gave his name to the Ramelet hooks, as none of the phlebectomy hooks on the market at that time satisfied his requirements. His four text books on phlebology are used as reference works and have already sold more than 100,000 copies. Over the years, generations of up-and-coming phlebologists have sat in on his surgical procedures. For the most part , Dr. Ramelet’s medical career has taken place outside of university clinics, and he stresses: “It is a great honor to receive the Ratschow Medal as a practicing dermatologist and angiologist. However, I also consider this award as recognition for Swiss phlebologists, with whom I have been able to achieve so † much.” life magazine 2014/29 NEWS ErgoPad ski and skate winter sports foot orthoses Perfect control on snow and ice Alpine skiing, snowboarding, ice hockey – many winter sports force the feet into a static position. Tilting to the side and changing pressure loads also put strain on the feet and joints. The ErgoPad ski and skate winter sports foot orthosis is specially designed to cope with these strains and supports typical movement patterns. As usual , the orthotic core with patented weightflex technology takes on a supporting role – and the plastic used in foot orthoses designed for sport is much more flexible than the type used in orthoses for work and leisure use, for example. This adaptation is important , because the feet have a much greater range of movement and the forces acting on them are significantly stronger during sporting activities. The effect of the core on the torsional stability of the feet reduces muscle fatigue and thus also prevents injuries caused by overloading. The orthotic core is coated in polyurethane for a long-lasting cushioning effect. The soft foam enables the surface of the foot orthosis to be molded to ensure that it provides the foot with the stability it needs, particularly during sideways movements. The heel cup guides and stabilizes the foot , despite the forces acting on the sides. The toe bank under the fourth and fifth ray stretches the toes, thereby increasing the area of the sole of the foot in contact with the foot orthosis, and with the shoe, for improved control. The stretching also relieves the Achilles tendon. Additional sensorimotor spots stimulate and strengthen the foot muscles. Finally, the top cover is also optimized for use in cold weather – it regulates heat and † keeps the feet warm. The ErgoPad ski and skate supports the typical movements associated with winter sports such as alpine skiing or snowboarding. Chilean Phlebology and Lymphology Foundation “All of our patients who undergo radiofrequency endoablation for great saphenous veins or posterior tibial perforators leave our clinic wearing class 2 compression stockings,” says Dr. Alvaro Orrego Díaz, President of the Chilean Foundation for Phlebology and Lymphology, founded in 1996. The aim of this non-commercial organization, which currently has around 60 members, is to continue improving the treatment and quality of life of patients with chronic venous or lymphatic disorders. As a result , great importance is attached to the constant exchange of knowledge among phlebology experts, lymphology experts, vascular surgeons, and other professional groups involved in providing medical care to patients with venous and lymphatic disorders in Chile. “We are involved in an intensive exchange not only among ourselves, but also with institutions in other countries, as will definitely be the case, for instance, at the XI Meeting of the Latin American Venous Forum this October in Buenos Aires. Exchange of this kind improves our understanding of these disorders and allows us to work together to improve the standards of treatment ,” says the internationally acclaimed vascular surgeon. When it comes to providing treatment with compression stockings, Dr. Orrego has had good experiences with products from Bauerfeind. He appreciates the high level of medical effectiveness provided by these German-made compression stockings and the fact that they are particularly comfortable to wear. Dr. Orrego adds: “Our patients keep saying to us that they feel very comfortable as well as reducing their symptoms!” For further information please visit www.fundacionchilenadeflebologiaylinfologia.cl. † 10 life magazine 2014/2 Have a look at the website of the Chilean Foundation of Phlebology and Lymphology.

Sports scientists and biomechanics at the University of Freiburg proved, for instance, a reduction in the knee adduction angle. Even patients with medial gonarthrosis can benefit from the correcting effect , as non-physiological strains exerted on the joint caused, for example, by a varus deformity, are a predictor for the disorder. The results of the Freiburg Institute of Sport and Sport Science agree with the GenuTrain’s mode of operation: Its effect is only felt during movement. A proprioceptive stimulus is induced from outside, thus stabilizing the joint. >>> 12 In treadmill tests, the Freiburg researchers were able to establish that the GenuTrain relieves the knee thanks to its biomechanical effects. life magazine 2014/2 FOCUS life magazine 2014/213 FOCUS >>> Dr. Dominic Gehring remains modest and is already looking ahead. “Yes,” says the young scientist in response to the results of the study, “this is something to build on.” Hold on a second, might be your first reaction to his scientific ambition, please first show us what has actually been done. Dr. Gehring and his team, headed by Prof. Dr. med. Albert Gollhofer, the director of the Institute, have every reason to be proud. The Freiburg group at the Institute of Sport and Sport Science of Albert Ludwig University has succeeded in proving that the GenuTrain active support by Bauerfeind has a correcting biomechanical effect: and this effect can have a positive influence on the wearer’s gait. Other studies have often focused on the sagittal plane of the knee. In their study, the Freiburg group turned to the frontal plane, that is, the plane that describes a varus or valgus deformity. And indeed: the GenuTrain can guide the knee back into a correct alignment. “A pioneering result ,” according to Dr. Gehring. The direction seems clear, especially for people such as Alfons Graf, who suffers from gonarthrosis. “The support has helped me,” 14 life magazine 2014/2 Dr. Dominic Gehring, who is leading the test series, attaches the sensors himself. says the study participant happily, who has returned to the laboratory today for the final measurements. The sporty sixty-year-old swaps his running shoes for measuring shoes and his long pants for shorts. “I used to run a lot – medium distances – I won the German championship in my age group,” he tells us. “Then the pain in my knee put me off sport. But it might be getting better now.” He has good reason to hope. when a patient with gonarthrosis is wearing the GenuTrain, the knee adduction angle is significantly reduced, thus minimizing the varus deformity.” A (more) physiological gait In addition, the Freiburg researchers were able to demonstrate an effect of the GenuTrain on more than the knee joint alone: Apart from the reduced adduction angle at the knee, an increased adduction angle at Significantly reduced adduction the hip was also observed. This seems quite conclusive, as the two joints form someAlfons Graf suffers from a pronounced varus thing like a coupled unit when walking. deformity and this deformity is where the The biomechanical effects of the GenuTrain study has shown the GenuTrain to exert a correcting influence. However, this effect is complement the results that Prof. Gollhofer, Dr. Gehring and their team members had not immediately obvious to the naked eye.

FOCUS Extracts from the cross-sectional study Evaluation of the biomechanical effect of the GenuTrain The aim of this study was to investigate the acute biomechanical mode of action of knee supports when walking in patients suffering from osteoarthritis of the knee. The study focused particularly on the adduction of the knee joint and the associated joint torque, because these aspects are considered to be connected to the development of osteoarthritis of the knee and its associated pains.

For Dr. Gehring, this is where proprioception comes into play. The compressing knitted fabric and the padded ring on the kneecap stimulate the receptors in the skin and the underlying muscles, which seem to guide the gait into correct alignment. A long-term study should substantiate the biomechanical effect Dr. Gehring would not be a sports scientist if he didn’t address the preventative effects of the GenuTrain for athletes in addition to its benefits in gonarthrosis patients. “Nearly all team sports have a varus/valgus load,” he says. “Think of football with its constant severe frontal strain on the knee. Players have constant varus stress when they turn corners. If the knee is further weakened by injuries, supports such as the GenuTrain can offer double support for athletes.” Whether the GenuTrain is used in prevention or in rehabilitation, the results of the Freiburg scientists show that the support’s effects on guided physiological movement are not a coincidence. A long-term study is now being carried out , which is expected to confirm this † cross-sectional study.

Albert Gollhofer. Although the results confirmed his assumptions, the head of the Institute of Sport and Sport Science at the University of Freiburg was still surprised by what the current study revealed. Biomechanics were the main focus of the cross-sectional study. Why? Prof. Dr. Gollhofer: The laws of biomechanics are the foundation of every movement. Going against them can lead to chronic complaints. People with typical bandy legs (extra-large varus angle) are very likely to develop medial compartment osteoarthritis. The higher knee adduction angle places more strain on the medial joint segment than on the lateral segment. When you succeed in straightening the knee with the help of a support to regain a symmetrical gait pattern, you can slow down the development of deformities. Proprioception requires the relevant receptors to be stimulated. There are many of these in the joint , the connective tissue, the muscles ... Prof. Dr. Gollhofer: We are concentrating on the mechanoreceptors. These are mainly located in the muscles around the knee and in the capsular ligaments. We play these proprioceptors together like an orchestra and “a good sound” is created when they coordinate the muscle contraction process appropriately and functionally. Injuries can cause particular problems at this point , however. We know that pain is conducted via the pathways of what we call group III afferents. These pain pathways strongly disturb the “good sound,” the rapid intermuscular interaction. Yet if we can improve the guidance of the joint by using supports, these afferents will send fewer 16 life magazine 2014/2 Prof. Dr. med. Albert Gollhofer, Albert Ludwig University of Freiburg. Pictures: Patrick Seeger, Bauerfeind How can a support influence the gait? Prof. Dr. Gollhofer: One way is through its proprioceptive effect. That is, through the mechanical stimuli it exercises on the soft tissue during movement. This creates feedback which is sent to our central nervous system and causes the muscle actions to change. The aim is a functional result. In the present case, the magnitude of the effect surprised me, although I was aware of the potential of the GenuTrain due to previous studies. FOCUS signals, which restricts the pain. And this has an immediate effect on the gait. To what degree are these rapid reactions only psychological? Prof. Dr. Gollhofer: Only to the extent that the central nervous system knows: I am not alone. Reflexes in the peripheral areas are constantly regulating muscular control , every fraction of a second. This can be seen in the leg swing and stance phases, for example. Even before the body weight bears down, that is at the end of the swing phase, neuromuscular control ensures that the leg extensors are pre-activated in order to immediately provide for the necessary stability in the stance phase. “This cross-sectional study proves that the GenuTrain has cross-joint effects.” The original on the knee: GenuTrain Shaping functionality The active support consists of an anatomically-shaped compression knit with a ring-shaped, functional cushion, the Omega pad. The pad relieves pain by transferring the therapeutic pressure of the support from the kneecap to the soft tissues of the knee region. Two nubs on the lower edge of the pad, the Hoffa pads, exert regulated pressure on the infrapatellar fat pad and stimulate the sensorimotor receptors located there. This supports the pain-relieving effect. Furthermore, direct pressure on the kneecap is relieved. The lateral wings of the pad form an omega symbol (Ω). Their role is to ensure that the meniscus parts are held in an anatomical position, which also reduces pain. (Prof. Dr. med. Albert Gollhofer) This also involves the ankle ...? Prof. Dr. Gollhofer: Of course, the ground reaction vector works from below. If the force is incorrectly introduced into the system, the possibility of counter-reactions in the knee is decreased, which is even worse further above. A stable gait comes from the bottom up. It makes sense to think about a bottom-up strategy using an ankle orthosis together with the GenuTrain, for example, for general instabilities. This cross-sectional study proves that the GenuTrain has crossjoint effects. The biomechanical influence of the support on the knee joint also causes significant changes to the hip. Can the results of the study actually be transferred to real situations? Prof. Dr. Gollhofer: When you measure specific effects in laboratory conditions, you ask yourself: How long will the effect last in everyday life? That’s exactly what we are trying to establish with a long-term GenuTrain study. Of course, we also know that all externally introduced changes to ingrained conditions will encounter a biomechanical state that has been established over years. Secure hold for the knee joint When walking or running with the GenuTrain, the muscular contractions cause the pressure exerted by the support to increase and decrease, resulting in an effect similar to an intermittent compression massage. This stimulates the metabolism and helps reduce swelling and effusions of blood more quickly. In addition, wearing the support stimulates the proprioceptors in the soft tissue of the knee and on the skin. The surrounding muscles are activated and long-term stabilization for the joint is achieved. GenuTrain: Active support for relief and stabilization of the knee. High level of comfort The material and shape of the GenuTrain knee support have a functional design for optimal effect and a high level of wearing comfort. The breathable, skin-friendly knit adapts to your every movement , without constricting or slipping. The material is soft and elastic at the edges of the support and in the sensitive area at the back of the knee. Lateral spiral stays ensure that the knee support keeps its shape during movement. Integrated donning aids make the supports easy to put on with little effort.† A patient who has an extreme varus deformity in the knee joint has adapted to a specific pattern with their ligaments, muscles and tendons. We can’t change that all at once. Patterns of movement and long-term adaptations in the soft tissues can only be coupled to new conditions over a long period of time. We also expect this from a support system. Ideally, the long-term study will show that constantly wearing the support over a long period of time causes the tendon and muscle lengths to return to a biomechanically balanced state. This would convince patients in everyday life. The initial results of our longterm study actually seem to confirm this type † of effect. life magazine 2014/217 MEDICAL LumboTrain active support Free movement of the muscles A new study proves: The “phantom” of muscular atrophy when wearing a support doesn’t exist.

That is why she chooses to travel with the 49er FX, a particularly fast boat class for women. When on shore, the Brazilian native likes to use the active support LumboTrain Lady for lumbar support. Boating is in her blood: Her mother taught her how to sail , and her father, Torben Grael , holds five Olympic medals in various boat classes, as well as six world champion titles. “You might say I started sailing in the womb,” says Martine Soffiatti Grael with a smile. “My mother even participated in a regatta when she was nine months pregnant with me.” At the age of four, little Martine started her first “real” boating training, and at age eleven she competed in her first race; at 13 she won her first national title.

But after a healthy childhood, something went gravely wrong as a teen. A sprain here, a dislocation there. Stress fractures and tendonitis that took forever to heal. Four major knee surgeries. Her list of injuries continued to lengthen as her body progressively worsened. “Growing up all I ever wanted to be was an athlete, first in soccer, then in basketball ,” the 26-year-old Tennessee resident says, “but by the time I was a student at Clemson University, I was struggling to simply walk around campus.” In November 2009 Ashley Eriksen dislocated her sacrum. “That’s when things really began to go downhill for me,” she comments, “and my joint laxity really began to show. The more muscle tone I lost , the more problems I had.” Finally, in January 2012 her many injuries were recognized not as isolated occurrences that could be attributed to overuse or accidents, but as symptoms of escalating Ehlers-Danlos Syndrome (EDS): a group of heritable connective tissue disorders, characterized by articular (joint) hypermobility, skin extensibility and tissue fragility. More stability, less pain Like many people with EDS, Ashley Eriksen went undiagnosed for years. Even after a diagnosis, she found herself searching for answers to her pain. Scouring the internet one night in desperate search of a brace that would help relieve her severe low back and sacral joint pain, she found the LumboTrain support brace by Bauerfeind. EDS patient Ashley Eriksen: “I was absolutely amazed the first time I put the LumboTrain on.” them into her daily life, “I love the way I can combine and overlap braces based on what activities I’m doing and how much support I require at that time. The soft braces make excellent training aids, the viscoelastic gel inserts are incredible for tendonitis.

Bauerfeind products as a key part of the care regimen As the Director of the Adult Genetics Program at the Harvey Institute for Human Genetics at the Greater Baltimore Medical Center, Dr. Clair Francomano treats patients with EDS and similar conditions almost every day. “On average, we see about 12-15 patients with these conditions every week, and I do telephone consultations for 6-8 established patients weekly as well ,” she says.

The fabric breathes and the supports are effective but not intrusive. Bauerfeind’s history as a textile manufacturer plays a key role in the quality of their fabrics, I’m sure,” Dr. Francomano says confidently. The products meet the highest medical standards and are tested in scientific studies. Personalized support As important as their products are to an individual’s health, Bauerfeind also goes the extra mile to provide personalized support for EDS patients – a notable fact that is not lost on the doctor. “The interest that Bauerfeind has shown in supporting patients with EDS also contributes to my enthusiasm for their products. Bauerfeind has established a hotline so people can find the closest durable medical equipment retailer to their home,” Dr. Francomano adds. For clinicians working with EDS patients, she emphasizes the value of using Bauerfeind compression hosiery. “Many patients with EDS and related disorders experience a condition called POTS – Postural Orthostatic Tachycardia Syndrome,” she explains. “This is a multi-faceted condition, but one of the important components that contribute to the problem is pooling of blood in the legs when people stand up. Compression hose can prevent that pooling from taking place and keep the blood in circulation to the lungs, heart and head. The Bauerfeind compression hose are really in a league of their own in terms of comfort and ease of use.” EDS specialist Dr. Clair Francomano, Greater Baltimore Medical Center, Shane Robinson, Executive Director of the Ehlers-Danlos National Foundation (EDNF), and Sandra Chack, Chairwoman EDNF Board. 22 life magazine 2014/2 A Closet Full of Braces David Griggs, of Durham, North Carolina, was the first person in the United States with EDS to wear Bauerfeind products as part of Pictures: Ehlers-Danlos National Foundation, Greater Baltimore Medical Center >>> People with EDS have joint laxity due to a hereditary weakness in their tendons and ligaments.

That’s why she recommends Bauerfeind products as a key part of her prescribed care regimen for EDS patients. “Bauerfeind soft braces* alleviate symptoms and pain by providing support to the joints,” Dr. Francomano explains. “Since the joint is supported, the muscles around that joint are not working overtime to stabilize the joint , and they will stay in a relaxed state that is not painful.

They don’t help our condition. For me, wearing support braces was a complete waste of time until I discovered Bauerfeind. I used their braces continually for three months before I realized I was using them less and less. That’s when it dawned on me. Our biggest problem is we don’t have time to heal before we re-injure ourselves.” David Griggs believes that Bauerfeind support braces “give back what EDS takes away from us – time to heal.” As a father, that’s the very thing he wishes for his children.

A study shows that even a small amount of support might have a significant impact: enabling adolescents to continue to be physically active. Three different therapeutic approaches Dr. Jan Joost Wiegerinck, an orthopedic specialist at the Academic Medical Center in Amsterdam, recently conducted a study involving over a hundred adolescents affected by Sever’s disease. The study examined a variety of treatment options in terms of their effectiveness and practicability. The study focused on three nonsurgical therapeutic approaches. The first approach was called “modification of activity levels” or “wait and see.” This involved test subjects being asked to simply avoid painful movements. The second approach was entitled “heel raise.” This approach involved the use of the Bauerfeind viscoelastic heel cushion 24 life magazine 2014/2 Author of the study: Dr. Jan Joost Wiegerinck from the Academic Medical Center in Amsterdam. Pictures: Astrid Mulder, picture-alliance/Oliver Killig Sever’s disease, also known as calcaneal apophysitis, is a common form of chronic heel and ankle pain affecting especially children and adolescents. The condition causes inflammation at the site of the attachment of the Achilles tendon to the calcaneus (heel bone). Other forms of chronic heel and ankle pain include heel spur and achillodynia (Achilles tendon pain). Sever’s disease (named after James Warren Sever, an American orthopedic surgeon, 1878– 1964) mainly occurs during adolescence. Typical symptoms include pressure pain on the calcaneal tuberosity, often combined with swelling and redness of skin, generally on both feet. Symptoms usually resolve after adolescence. Causes might include factors such as obesity as well as excessive strain on the calcaneal apophysis, the base of the Achilles tendon, during intense exercise. Seeing as the pain intensifies during exercise, many physically active young individuals feel unable to continue with their sporting activities. Considering the fact that joy of movement and enthusiasm for exercise is usually developed and consolidated at an early age, this is especially unfortunate. MEDICAL ViscoHeel. Test subjects were asked to wear the heel cushion in their shoes as often as possible. The third group of test subjects underwent a “physiotherapeutic stretching and strengthening program:” This involved performing specialized targeted exercises to stretch and strengthen specific muscle groups at the clinic and at home. All three treatments were aimed at relieving the adolescents’ chronic heel and ankle pain. might be caused by circulatory disorders due to excessive strain or growth, as well as injuries caused by repeated microtraumas. “Nevertheless, the clinical conditions and the type of patient remain very specific,” explains Dr. Wiegerinck. “Thus, using pressure testing to the attachment of the Achilles tendon to the apophysis of the heel , it is relatively easy to diagnose the condition – while imaging techniques can only help exclude other con- ViscoHeel Bed for your heel The ViscoHeel heel cushion reduces pressure discomfort under the heel , as well as pain around the Achilles tendon. It can also effectively reduce shock loads on ankles, knees, and hips. The anatomically contoured heel cushion made of highquality silicone relieves muscles and tendons in the calves. Durability is one of its particular benefits. The high-quality silicone can continue to take the strain for a long period. The heel cushion is also gentle on the skin and easy to clean. It absorbs impacts under the heel without † slipping. Sever’s disease causes pain when playing football. “We knew in advance that all three methods would be valid,” explains Dr. Wiegerinck. “They are all methods that are also applied at our clinic in Amsterdam.” This means that the Dutch researchers were able to gather additional retrospective data on different treatments for Sever’s disease. Now, conducting a prospective study, their aim was to find out which of these three approaches would be the most effective “based on strict EBM guidelines,” emphasizes the orthopedic specialist. Until now, no standard scientific guidelines for treating the disease had been compiled. Consequently, to paraphrase literature, treatment often turned out to be a “guessing game.” Neither is there any prevalent scientific consensus as to the causes of the disease. It is assumed that an imbalance between the muscle-tendon structure and the development of the skeleton in adolescents is responsible for the painful inflammation to the site of the attachment of the Achilles tendon to the apophysis of the heel.

In this area, compression stocking specialist Bauerfeind offers its customers a strong sports stocking duo for endurance and stop-and-go sports. Anyone who participates in long-distance running or cycling is familiar with the feeling of heavy, tired legs. This is caused by the vessels expanding and losing their tension. With the new Compression Sock Performance, available from summer 2014, endurance athletes can now give their veins the ideal support. The sports stocking’s pressure profile is based on medical standards. The continuous compression decreases from ankle to calf, which improves venous reflux and the removal of lymphatic fluids. At the same time, the gentle compression stabilizes the calf and reduces typical muscle vibrations, thus preventing premature fatigue. Better support is provided for muscles over long distances, so they can continue to perform more effectively. Stability for the ankle The Compression Sock Training sports stocking is especially designed for stop-and-go 26 life magazine 2014/2 The Compression Sock Performance sports stocking meets the needs of endurance athletes. The Compression Sock Training sports stocking provides protection in stop-and-go sports. Pictures: Bauerfeind Quicker recovery The positive impact on circulation and the muscles protects the vein system when it is under persistent stress, which in turn promotes a quicker recovery. Just how much endurance athletes benefit can be seen in a medical study* carried out during the 2011 Paris Marathon. The participants wore the previous model of Compression Sock Performance, which is identical to the new sports stocking in terms of compression strength and therapeutic gradient. They reported less muscle pain, a reduced feeling of swelling, and much better muscle recovery in the first four days after the race. Their calf veins had not dilated during the race despite the increased strain. The knit of the Compression Sock Performance is made of fine, breathable microfiber. It can regulate heat and channel moisture away from the skin, creating comfortable micro-conditions. This has a twofold benefit during sporting activities. In addition, the microfiber makes the new sports stocking particularly light , yet still hard-wearing. MEDICAL sports, meaning sports that involve rapid turning and jumping movements such as football , basketball , or tennis. It features special functional zones with gentle compression. The stocking’s taping zone helps to create a feeling of greater stability in the ankle, while its muscle-toning zone specifically stimulates the calf muscles during movement. This is particularly important in these ball sports that put a great deal of stress on the ankle, because a sense of instability can quickly take the fun out of exercise – especially in people with a previous injury or naturally weaker ligaments. The Compression Sock Training uses the same active principle as a tape bandage to create a feeling of improved stability in the ankle. The “taping zone” with a “figure of eight” design wraps around the instep and heel. The firmer, compressive knit stimulates the skin’s sensors and the deep sensors in the muscles, tendons, and joint. The improved proprioception supports the ligaments and improves coordination, providing greater security when changing direction quickly. The stocking therefore also offers increased protection from injuries. Muscle stimulation In the calf area, the “muscle-toning zone” also exerts gentle compression at certain points and counteracts tiring muscle vibrations. Its asymmetrical anatomical shape specifically stimulates the muscles during movement , facilitating gentle muscle building. Like the Compression Sock Performance, the Compression Sock Training’s heel cushion eases the strain on the Achilles tendon and protects this sensitive area from pressure and rubbing when it is under great stress. Additional toe, forefoot and heel padding absorbs impact and ensures a firm grip in the shoe. The stocking’s high-quality breathable Lycra Sport material guarantees the required moisture transfer during sporting activity and creates pleasant conditions for the feet. Simple size selection The appropriate size of the Compression Socks Performance and Training is determined by the shoe size and the calf circumference, as the leg muscles of athletes can vary considerably. The Compression Sock Compression Sock Performance Compression Sock Training Compression over a large area, consistent therapeutic gradient that complies with medical standards Compression at certain points in the taping zone around the ankle and muscletoning zone on the calf Improves circulation and protects the veins from overloading Improves coordination thanks to its stabilizing effect on the ankle and calf muscles Reduces muscle vibration (due to the compression) and prevents premature muscle fatigue Reduces muscle vibration (due to the compression) and prevents premature muscle fatigue Ideal for use with the ErgoPad run & walk sports foot orthosis Ideal for use with the ErgoPad ball & racket sports foot orthosis Recommended for endurance sports Recommended for stop-and-go sports with quick changes of direction Performance is available in black, white, and Rivera, a shade of turquoise.

This private clinic mainly draws its customers from among hip and knee patients. When treating knee problems, a task which also involves the use of persuasion, Dr. Duval uses a medical aid that fits the bill in many respects. Orthopedic surgeon Dr. Nicolas Duval makes a specialty of problems connected with the adult hip and knee. What is the typical profile of a patient with osteoarthritis? 28 life magazine 2014/2 Dr. Duval: The typical patient , often at a high risk of osteoarthritis, who comes to us is aged between 35 and 55 and has always been actively involved in sport. These patients have either sustained an injury as a result of this or suffered an ever-increasing number of microtraumas over the years, associated with doing sport. These major or minor injuries often end up as knee problems. They experience pain while walking, and their knee swells up. Therefore, degenerative arthritic processes are not the prime concern for the patient or for us. We are not a trauma center either. It is predominantly younger people who come to us and who need our assistance because of a strain that has been affecting them for lengthy periods of time. The risk of osteoarthritis is always present. Osteoarthritis is incurable. But what can you do? Dr. Duval: Treatment methods have been evolving all the time in recent years, as in other areas of medicine. But it is a tough task tackling osteoarthritis problems from scratch. Cartilage tissue mainly comprises collagen fibers, has a poor blood supply, and Pictures: Agence 4 Saisons, Bauerfeind How many patients do you treat at your clinic? Dr. Duval: Around 2,000 patients a year. We operate on between 300 and 500 of them. We carry out arthroscopies on about half of these patients, with the other half mainly being fitted with hip and knee endoprostheses. It’s mostly people actively involved in sport who come to us. We see many patients with knee osteoarthritis at every stage, closely associated with the corresponding cartilage damage. MEDICAL has only minimal to absolutely no regenerability. Research has focused on particular biological methods. One area of focus is growth hormones. I’m personally involved in research in the field of glucosamines. These are substances required for the metabolism of the cartilage layer. get back slowly to their normal everyday activities. The third group includes patients with osteoarthritic changes to the lateral sections of the joint , on the lateral tibial plateau or the lateral femoral condyles, mainly associated with instability. All three groups present a real challenge for the support , which copes wonderfully with them. But you can still help your patients now. Dr. Duval: Yes, I can, because amazing What can you achieve using the knee support advances have also been made in orthopedic GenuTrain S? products. I discovered the GenuTrain S two years ago. The standard GenuTrain was my preferred choice prior to this. This product is already in its seventh generation of manufacture. It was my favorite support for providing my patients’ knees with greater stability and alleviating pain. That’s until I then found out about the GenuTrain S. It offers me even more options for guiding the joint. all , elderly patients who are no longer so involved in sport give a completely positive endorsement to the support and guidance they receive from the splints. What can patients themselves do to contribute to their treatment? Dr. Duval: There’s a whole host of things they can do. Many need to change their mindset and their lifestyle. I try to explain to them that they really have the best pos- The GenuTrain S active support with lateral joint splints supports the knee joint for indications of slight instability, arthritis or osteoarthritis of the knee. How do you incorporate this support into your treatment concept? Dr. Duval: The significant role played by the GenuTrain S in treatment can be gauged Splints for added protection In the GenuTrain S (S for splints), lateral joint splints guide the knee’s movements. The splints can be heated and reshaped, and can therefore be adjusted to the anatomy of each individual. The joint muscles are also stabilized further by the elastic Train Active Knit with its integral pad. by the large range of patients for which it can be used. We see three main groups that it is relevant for. The first group does not yet have any pronounced symptoms of osteoarthritis. In most cases, the defective cartilage is not directly on the joint surface. These patients want to continue doing sport. The second group that I treat using the GenuTrain S is made up of patients who have already had surgery to regenerate the cartilage. In this case, I use the support for the first time approximately two months after the operation, when the swelling has subsided and the patient is intends to The GenuTrain S active support with lateral joint splints supports the knee joint for indications of slight instability, arthritis or osteoarthritis of the knee. Dr. Duval: First and foremost , it offers patients stability. The support stays in the exact place it is needed. It doesn’t slip. This is absolutely vital for patients and is a feature of the GenuTrain S that they also greatly appreciate. And it also looks good. Other supports that they have tried often shift from the correct position when they are doing sport. This is often the case particularly with overweight patients. The special manufacturing method used for the GenuTrain S prevents it from slipping. The lateral splints offer a good compromise between stability and mobility. Most of sible joint for doing exercise on a normal basis. However, part of this involves them definitely doing exercise and keeping active. And this also means specifically people who are overweight getting back into a normal routine. The GenuTrain S can help them do this. But the patients must take the first step themselves.

The same applies for the donning of compression stockings, which can be a difficult and time-consuming task. How do the people in that target group experience it , and what relief can a donning aid like the VenoTrain glider plus by Bauerfeind actually bring? These and more questions are currently being answered at the Meyer-Hentschel Institute in Saarbrücken, Germany. The institute specializes in the testing of age-specific designs, and is seen as a pioneer in marketing campaigns aimed specifically at senior citizens in Europe. The age research suit Age Explorer, the prototype of which was introduced by Dr. Gundolf Meyer-Hentschel in 1994, is both a method and a tool. This very special suit allows the wearer to experience the world the way an older person would. This process, which the institute uses in 30 life magazine 2014/2 the development and testing of products and projects for a variety of life situations, is continuously growing in importance in light of demographic developments. Its findings play an important role in the future of packaging, cosmetic products, residential housing developments, public transport , and also in donning aids for compression stockings. This product underwent extensive testing at the institute, comparing the VenoTrain glider plus with a standard donning aid from another manufacturer. Bauerfeind life was given a look behind the scenes at the process in action. Panoramic view of life as a senior citizen The testing process involved three experts who were in the age group 50 to 65 to put on a waistcoat , jacket , and trousers containing additional weight. Each of the subjects would therefore carry around an additional 16 kilograms which gave them the feeling of having considerably less muscle power. Their elbow and knee joints were additionally limited in their movement with a combination of bandages and splints, while gloves impeded the sense of touch and fine motor functions. In order to give the test subjects an absolutely authentic experience of life beyond the age of 70, they were additionally fitted with earphones and a helmet complete with a yellow tinted visor. “The visor inhibits the field of vision both vertically and horizontally, and also simulates the changes in color perception that often occur in old age – for example in individuals developing cataracts,” explained Dr. MeyerHentschel. The earphones helped simulate the age-typical hardness of hearing. The overall idea of the Age Explorer is to gain a more holistic understanding for a naturally aged target group. The basic premise is reduced mobility, deteriorating dexterity, and declining muscle power. Validity tests have shown that the tests conducted with the Age Explorer deliver a very high rate of con- Pictures: Rainer Kraus Compression stockings are a meaningful medical product – but putting them on requires energy and time – especially in older patients. The donning aid VenoTrain glider plus by Bauerfeind makes the process a lot faster and easier. A test conducted with the Age Explorer, an age research suit , has shown that in particular older patients benefit greatly from its use. MEDICAL Left to right: Dr. Gundolf Meyer-Hentschel lends the life editor a hand to put on the Age Explorer. Then it is time to put on the compression stockings. VenoTrain glider plus makes it an easy job – despite the additional hindrances. gruence with tests involving actual consumers of that age group. “Our tests are actually more stringent in terms of the products,” explained the institute’s founder. But let’s continue with the test. The subjects were comprehensively trained in the technology side of the donning aids before proceeding with the practical part of the test. Step one: sliding the compression stocking over the semi-circular basket of the two donning aids. Then came the donning. The core questions here were: “How well does the process work with technical support?” and “Can older people with minor physical handicaps use the aid?” The test subjects were asked to don the compression stockings between 10 and 15 times within around one-and-a-half hours to gain valid data. The findings of the expert: “The donning aids help compensate for the natural deficit of the stockings.” After all: there is no product that can conventionally be donned as if by magic. The donning aid is therefore a meaningful support tool. Bauerfeind life was permitted to try out the VenoTrain glider plus using the Age Explorer, and can underline the truth of these findings. Despite the simulated handicaps of age, the compression stocking was easily pulled onto the basket. The actual donning VenoTrain glider plus This device helps patients to put on their compression stockings correctly. People with limited mobility or dexterity will benefit greatly from the practical donning aid featuring extensible grips. These function like an extended lever, allowing the stockings to be pulled up easily without having to bend over excessively. With the grips folded away, the compact VenoTrain glider plus requires only minimal storage space. of the stocking was just as easy: fold up the lateral grips of the VenoTrain glider plus, set the device almost flat onto the ground, slip the foot into the stocking while slightly lifting the donning aid and pulling the lateral grips; then simply slide the stocking upward in one go. The entire exercise required no excessive bending, and there was no need to work the tight stocking bit by bit over the heel and calf. A truly eye-opening experience. “This is a very relevant tool , as usually you would require both physical strength and dexterity to put on compression stockings.” Dr. Gundolf Meyer-Hentschel was full of praise for the practical and easy to understand principle of the donning aid. He sees an additional benefit in the design of the tool: VenoTrain glider plus is easily folded away after use and needs only minimal storage space. His conclusion: “That is a huge advantage. The more inconspicuous and low-key the tool † design, the better.” life magazine 2014/231 IN MOTION The thrill of roller coasters An unforgettable ride They promise a enthralling ride at the borderline of what the human body can handle – alternating between tension and relief. Modern roller coasters are works of art in terms of engineering and aesthetics, matched perfectly with calculated suspense. They combine thrill with a rush of speed, great heights with free falls and spectacular cars with impressive special effects. Picture: Getty images/Chad Slattery “Always faster, higher, more spectacular” has been the trend in roller coaster construction over the last few decades because the public loves new records and extremes. >>> 32 life magazine 2014/2 IN MOTION life magazine 2014/233 IN MOTION >>> Parks across the world outbid each other with new attractions. Visitors can experience countless steel and wooden roller coasters whilst sitting, standing, hanging over the rails or even lying down. Roller coasters are installed in shopping malls, apartment blocks or on TV towers. For passengers, the most spectacular effects are speed and rapid changes of direction: Experts call the feeling of weightlessness when the seats are lifted up – such as when flying across a parabolic-shaped hill – “airtime.” Fractions of a second later, the passengers are pressed into their seats – and feel up to six times their own body weight (6 g). Spectacular rides full of effects Even today, he is not lacking ideas. Only last year, Michael Klose and his colleagues created yet another innovative success: The looping rails of the “Full Throttle” roller coaster in California, US – at nearly 50 meters, one of the highest in the world – can be ridden on the inside and the outside. “There is an increase in spectacular rides full of effects,” Michael Klose explains. Dark rides with enthralling missions in space, Nordic sagas and fairy tales, enhanced by smoke, and sound and lighting effects. Spectacular installations cost between 15 and 20 million euros, some significantly more. 34 life magazine 2014/2 When designing installations, the challenge for engineers is to create an adventure that takes the breath away from hard-core fans without going beyond the constitution of the average visitor. Below: Taking a dive in the Vanish Roller Coaster in Yokohama. Although there is a construction boom of new rides in Asia, the US are still the benchmark: parks with up to 25 rides being quite common there. “But Europe and Germany have also come a long way,” Michael Klose adds. For him, experiencing speed and height is still the top criterion for visitors. The Freiburg sociologist and entertainment scientist Sacha Szabo believes the appealing feature of a ride can be explained by the opportunity to fully focus on the present. “In that moment , you forget your own mortality, you don’t think about the past or the future,” explains Sacha Szabo. At the same time, roller coaster rides also cause positive stress – including the immediate relief of a safe return. By the way: Statistically speaking, roller coasters are amongst the safest vehicles in the world. † Superlatives on rails • The highest steel roller coaster in the world: “Kingda Ka” at the Six Flags Great Adventure, New Jersey, US (139 meters). • The longest: “Steel Dragon 2000” at the Nagashima Spa Land in Kuwana, Japan (2,479 meters). • The fastest: “Formula Rossa” at Ferrari World, Abu Dhabi (240 km/h). • Roller coaster with the steepest descent: “Takabisha” at Fuji-Q Highland near Tokyo, Japan (121 degrees). • Roller coaster with the most loops: “The Smiler” at Alton Towers, Alton, UK (14 loops).

And yet , the highest heights, speeds and lengths have already been reached: “There will be other small records, but basically all the possibilities have been exhausted,” says Michael Klose. The 29-year old graduate engineer works at Stengel Engineering in Munich, Germany, founded by Werner Stengel , who is revered by his fans as the “roller coaster guru.” His office has produced the calculations for over 600 roller coasters across the world, including Kingda Ka, Takabisha and The Smiler (see boxes), as well as various milestones in development: It was Werner Stengel who introduced the softer start and exit of the looping in 1976 to reduce the risk of spine compression and neck injuries. He is also the creator of the heart-line principle: The center of rotation of the rails is now located around the level of the waist , which also reduces the load on passengers.
