Creating the Annual “picture”

Posted By IADMS Program Committee, Thursday, September 10, 2015

The Annual Meeting is the highlight of the IADMS calendar. The Program Committee (PC) has the complex task of piecing together the various jigsaw puzzle pieces in order to produce a scientific conference that is both educational and enticing. The committee is made up of four long standing IADMS members: Ginny Wilmerding, Marika Molnar, David Weiss and Alexander McKinven. The mix of professions, nationalities, backgrounds and personal interests means that each of us has a unique perspective on how the Annual Meeting should evolve.  Every Annual Meeting has its own character, with many variables, but the PC strives to develop each one and make it even better than the last.

When the PC gets involved, the location for the Annual Meeting has already been chosen and the Annual Meeting Producer is already working with the local host team. They have an understanding of the size/space available and times slots needed to be filled. Think of this like the template on a canvas with the Program Committee ‘artists’ waiting to know the colours of paints, (the abstracts), they will be given.

After the abstract submission deadline, the committee works on a strict timeline to ensure the integrity, standard, and relevance of the conference by:

·         Making sure the submitted abstracts follow appropriate international ethics standards and any commercial interests are disclosed,

·         Working with the Continuing Education Committee to ensure CME credits are available for healthcare professionals,

·         Distributing the abstracts to a group of independent reviewers who, blinded to the abstracts authors, will perform the task of grading the submitted abstracts,

·         Categorizing the abstracts into relevant topics/subjects to ensure flow, and

·         through their networks, inviting learned colleagues to fill the ever popular and always well attended Clinical Symposia.

As the number of submitted abstracts increases each year - 123 of them in 2006, and growing to an all-time high of 228 of them in 2015 - the task of selecting the best presentations gets harder and harder. Throughout the selection and planning process, there can be unforeseen changes to the program due to presenter’s work commitments, medical problems, flight cancelations, and electronic meltdowns; the Program Committee team are in regular contact with the selected presenters. (The sooner we know about these issues, the better!)

When October comes, hearing the buzz, seeing the presentations live, and being involved in the discussions makes all the hard work worthwhile. To know that we are helping the international dance scientists, clinicians, and researchers have a platform to showcase their work and to see the  satisfaction from the ‘painting’ you helped develop, grow, and stand on its in own is a very satisfying process for the four of us!

Dancers - More Power To You!: Video from the 2014 Annual Meeting

Posted By Jatin P. Ambegaonkar PhD, ATC, Monday, August 31, 2015

IADMS Ambegaonkar from Steven Karageanes on Vimeo.

Watching a dancer perform can be breathtaking and fun. Being a dancer is hard! This is because dancer’s movements often involve jumping and landing. To safely perform these explosive movements, dancers need good power in their lower body (Lower Body Power - LBP). Understandably, 70% of all dance-related injuries are to the lower body. Dancers are also supposed to have better balance than non-dancers. In athletics, sprinters with better strength and power and balance have better performance. In modern dance, aesthetic performance and jump ability are positively correlated to each other. However, research investigating potential interrelationships between LB power and balance among dancers is lacking.

We examined (a) the relationships between LBP measures and balance in dancers, and (b) the relative contributions of LBP to predict balance in 61 female collegiate dancers (18.3 + 0.7 years, 164.7 + 7.3 cm, 61.7 + 9.5 kg and with 11.3 + 4.8 years of dance experience). The dancers performed three vertical jumps on the Just Jump Mat (Probiotics, Huntsville, Alabama USA) and we calculated Peak and Average Power. Dancers also performed the Single leg hop for distance, which examines horizontal LBP. We measured balance using the Star Excursion Balance Test, a commonly used valid and reliable test of balance, which has been found to predict the risk of injury.

Our primary findings were that all balance and LBP measures were positively correlated to each other. We found that the more powerful dancers also had generally better balance.  Our findings thus challenge the often-pervasive myth among that being more powerful equates to being more muscular, which then can worsen dance performance. In fact, our evidence supports the opposite view that for dancers, being more ‘powerful’ also translates as being more ‘balanced’ - a MUCH desirable quality!

We are excited with this finding as, to our knowledge, our results are among the first times in the dance medicine and science that we can say to dance teachers and healthcare professionals that dancers balance and power are positively related to each other. In fact, our data suggest that the three LBP measures collectively combined to predict almost 50% of the change in balance scores. Overall, for dancers being powerful is really a good thing!  Furthermore, prior researchers have noted that training can improve power, strength, and dancer performance. Combining these prior reports with our findings, we can recommend that dance medicine and science professionals need to encourage dancers to incorporate strength and power training outside of dance practice in their training regimens to improve balance and overall dance performance.

The female athlete triad in college dance students: Video from the 2014 Annual Meeting

Posted By Amy Avery, BFA, MS, and Jane Baas, MA, MFA, Monday, August 24, 2015

IADMS Avery Baas from Steven Karageanes on Vimeo.

Diet and exercise is an important factor in addressing the health related problems of the estimated sixty seven percent of American adults who are overweight or obese.However, diet and exercise can also become a potential problem when mixed with a strong desire to become or maintain a very thin physique.  Eating disorders can result from these desires, where harmful behaviors are used to lose weight or maintain a thin appearance.2 When taken to the extreme, the practice of excessive calorie restriction and expenditure can have severe health implications.3

            The Female Athlete Triad (Triad) can result from disordered eating patterns and can have severe health consequences.4 The Triad is an interrelated problem and includes three syndromes: 

     1.      abnormal dieting behaviors include restrictive eating, fasting, using diet pills,
                   diuretics, enemas, overeating, binging and purging,5 
     2.      amenorrhea, is characterized as the loss of menstruation, and 6
     3.      osteopenia or osteoporosis, is known as a decrease of bone mineral density. 

The Triad can affect the entire body and mind in ways such as:

·         a reduction in speed, endurance and strength.7
·         fluid and electrolyte imbalances, with depleted muscle glycogen stores and blood
               glucose which can increase risk of injury.
8
·         a higher incidence of  infection, anemia, and electrolyte disturbances; impaired healing,
               cardiovascular differences, osteoporosis and endocrine conditions. 8 Without the
               production of estrogen, bone health can be compromised leading to increased
               occurrence of injuries and osteoporosis. 

Without the proper intervention, the consequences of the Triad can be as simple as the loss of participation in physical activity or as severe as emaciation or death. 2,3 What may begin as a simple diet can lead to a psychological disorder, with eating disorders having the highest mortality rate of all mental illnesses.9

            The occurrence of the Triad is a growing concern among populations, such as athletics, who focus on body image and body weight . 4 This population includes dancers.  Research has indicated the figure to be as high as 60% or greater for athletes in particular sporting events. 10 Historically, having a thin physique has been essential for consideration in the dance world.  Unfortunately, this can encourage eating disorders that are associated with the Triad. 11  The prevalence is unknown in college dancers. However, it is known to be higher in the dancer population due to collective pressures to maintain a thin body. 12 It is a common occurrence for dancers to limit their food intake to meet the demands of professional expectations of body image.  Weight control is influenced by aesthetic considerations and body image.8 Much has been written concerning eating disorders in dancers. 5,8,12-15 However, few studies have been conducted regarding the Female Athlete Triad and the premature occurrence of osteoporosis.16,17

            The purpose of this pilot study was to discover the prevalence of the Female Athlete Triad in college dance majors and minors. An anonymous survey was used to collect data from the current female dancers at an American university to determine if a relationship existed between injuries and eating disorders. Sixty female dancers participated in the survey that included a combination of questions extracted from the Eating Attitudes Test-26 (EAT-26) and the Pre-Participation Evaluation from the Female Athlete Triad Coalition. Findings indicated that 25% of participants could be classified as being in the symptomatic range for disordered eating patterns and behaviors; 48% stated the absence of a monthly menstrual cycle; and 16.67% had sustained stress fractures. 

  

 


            Dancers with a higher eating disorder attitude tended to have more injuries. Further, the sample population had disordered eating patterns and that a relationship existed among the Female Athlete Triad symptoms. In addition, more educational resources should be implemented in dance courses, along with an increase in seminars, town meetings, and counseling services addressing the consequences of eating disorders.

 

A Need for Education

In 1998, the American College of Sports Medicine advised detailed approaches be established to identify, prevent and treat this syndrome. These strategies included education about the Triad for a wide range of individuals including teachers, choreographers, directors, coaches, trainers, administrators, health care providers, parents and the dancers/athletes themselves.  Identifying individuals who may be at risk is especially difficult in the dance population.  In a field where a preoccupation with weight and disordered eating is considered "normal," how can we determine when “normal” becomes excessive? Becoming familiar with the signs and symptoms may help increase the prevention of a full blown eating disorder. It is recommended by the NCAA that those who work with dancers and the students themselves need to be aware of the risk factors and symptoms. Being aware of the situation is the first step in changing behavior. A teacher or a coach can be influential in providing students and staff with the education they need to decrease the risk of Disordered Eating and the Triad. Instructors must promote intelligent knowledge to their students and be healthy role models for their students.

Promoting healthy choices is crucial to the wellness of their dancers. Robson and Chertoff 18 make the following recommendations:

• Encourage positive attitudes and healthy bodies;

• Provide information regarding calorie consumption and energy expenditure;

• Raise awareness regarding adequate nutrition and bone health;

• Be mindful of early signs of the female athlete triad;

• Advise vulnerable dancers to seek proper assistance;

• Insist on regular medical check-ups;

• Create strategies to develop ideal health and wellness resources for dancers.

Current research indicates a need for additional resources, education and information for dancers of all ages. This was especially true for dancers in a serious training facility.

A Welcome Message from the 2015 Annual Meeting Host Committee: Top 10 things to do on your trip to Pittsburgh

Posted By Andrea Kozai on behalf of the Host Committee, Monday, August 24, 2015
The Host Committee for the 25th Annual Meeting is incredibly excited to welcome you to Pittsburgh, Pennsylvania! Pittsburgh is a beautiful metropolis in the heart of Steel Country, and has transformed itself from an industrial powerhouse of yesteryear to a vibrant economy based in technology, medicine, and academics. There is lots to do and see, so we thought it would be helpful to share a list of our favorite parts of this city. Without further ado:

10. Visit the historic Strip District. Whether you're looking for local shopping or local food (breakfast at Pamela's is a must), the Strip is the place to be. Pittsburgh is a town proud of its sports teams, so pick up some black and gold gear while you're there!

9. Tour local movie sets. Did you know Pittsburgh is known as "Hollywood of the East"? Movies such as The Dark Knight Rises, The Perks of Being a Wallflower, Dogma, Jack Reacher, Night of the Living Dead, and Flashdance were all filmed here (and a few, including The Perks of Being a Wallflower and Flashdance, were set here too!) Create your own tour using suggestions from this excellent article.

8. Visit Fallingwater. A bit farther afield, Fallingwater is a home Frank Lloyd Wright designed for the Kauffman family of Pittsburgh. It is built over a waterfall and appears to not even stand on solid ground. It is a National Historic Landmark and is open for public tours. Click here for more information.

7. Take a walk from the Marriott City Center to Point State Park, located at the confluence of Pittsburgh's three rivers. See where the Allegheny and Monongahela rivers come together to form the Ohio river and take in the glorious views.

6. Visit one of Pittsburgh's many museums. The Carnegie Museums of Pittsburgh boast a number of options for art (including the Warhol Museum), natural history, and science. Or, check out the Toonseum or the Heinz History Center.

5. Get lunch at Primanti Bros. With several locations including one walking distance from the Annual Meeting, opportunities abound to experience this classic Pittsburgh eatery. Don't be surprised when your fries come on top of your sandwich instead of next to it!

4. Take a trip up one of the inclines for the best views of Downtown Pittsburgh (or, as the locals call it, the Golden Triangle.) See how many bridges you can count (Pittsburgh has the most of any city in the world, including Venice!)

3. See the artists of Pittsburgh Ballet Theater up close. On Thursday, Oct 8th the delegates of IADMS have a special opportunity to see a studio showing put on by Pittsburgh Ballet Theater. Afterwards, enjoy drinks and light bites with the artists. Sign up when you register for the conference.

2. Attend the Opening Reception and participate in the Silver Anniversary Auction. In honor of the 25th Anniversary of IADMS, a silent auction will run through the conference to raise funds for IADMS-IT. Donate something, bid on something, and be a part of the next 25 years of IADMS!

1. Learn, network, and participate in everything the 25th Annual Meeting has to offer! A fabulous program awaits you, so don't miss a minute of it.


For more ideas and assistance planning your trip to Pittsburgh, check out www.visitpittsburgh.com. See you in October!

Nutrition Research should drive advice and practice: which nutrients should the dancer be updated on and why: Video from the 2014 Annual Meeting

Posted By Jasmine Challis, BSc, RD, Monday, August 3, 2015

This blog looks at the information I presented at the 2013 IADMS conference in Seattle. It looks at an area where there is a lot of controversy and tries to steer a research based path to advise the dancer on current best practice considering the current evidence.

Introduction

Dancers interested in making sure their food and fluid intake optimises their performance are faced with a huge amount of nutrition information in magazines, newspapers, the internet, blogs(!), TV and radio programmes, Twitter and other social media, plus that from  teachers/colleagues/ peers/family and friends. It can take determination not to be drawn into believing the latest trend as to what is best. It is probably useful to remember that nutrition research changes knowledge slowly in almost every case, so if a claim sounds dramatic, it has probably been exaggerated or the actual information twisted to try and make a story.

When we think about nutrition we tend to think about energy, measured in either kcals (USA) or kjoules (Europe and Australia), which can come from carbohydrates and fats (and alcohol- though not relevant for training/performance), - and technically from protein. Although protein can be used as an energy source, it can’t then be used for its main roles in growth and repair so it’s not a viable option for most dancers. It is also the most expensive component of most meal plans so most dancers will have more of a challenge to take in enough protein to meet their needs than to have surplus to burn as a source of energy.

Moving on from energy we then need to consider the vast range of vitamins and minerals that humans, including and particularly dancers, need. There is ongoing research identifying new roles for established nutrients, such as Vitamin D having a role for a healthy immune system, as well as clarifying the roles of nutrients such as Vitamin E which we still don’t fully understand.

The tables below show the vitamins and minerals that are perhaps of most relevance to the dancer, and the body systems that are most important in dance and whether the nutrient may or may not be involved. Nutrition research is very challenging for a number of reasons. It is difficult to persuade people to keep to a fixed diet so that an experiment can be done to change just one food or nutrient; people do not all react the same; it may take a long time to see a difference, and all of this makes research very expensive and time consuming. Also, when trying to change a nutrient, unless it can be added to an existing part of your diet, for example adding folate to bread, then introducing more of one nutrient, means another typically must be reduced and this can impact your total energy intake which may in itself affect the results. Another problem is that large amounts of any nutrient is likely to do harm, and at extremely high intakes the body may process these nutrients differently compared to when taken in moderate amounts. 

  

There is also a problem that anyone can call themselves a nutritionist – though the title ‘Dietitian’ or ‘Dietician’ is legally protected – so there are many ‘experts’ who are taking some evidence (at best), and advising people without having the depth of knowledge to give the best advice. Always remember that if it sounds too good to be true, it probably is. And that nutrition is almost never black and white, because of the simple reason that if you make a change you are most likely taking something out of your meal plan to put something else in. If you take out sweets and put in fruit, your energy level as well as your intake of vitamins and minerals may well be better overall, but if you were eating a lot of sweets you will need to put in a large amount of fruit which may upset your digestive system at least initially (you may adjust in time) and also be acidic for your teeth and result in some damage over time. So what sounds like a very good change may bring a less welcome effect.

Small gradual changes you can sustain are best – avoid making huge changes that take a lot of time and effort unless your starting meal plan really needs a complete overhaul and is causing you problems at the moment.

So, think about your food plan, be honest with yourself; if changes would be helpful introduce them gradually and make sure you can keep up the new plan, along with the benefits it will bring, before making further changes. If you can find foods that you enjoy and that help you achieve your nutrition goals that is going to make keeping to a meal plan easier!

Injury Prevention Research: Investigating patellar tendon development in adolescent dancers

Posted By Aliza Rudavsky on behalf of the IADMS Education Committee, Thursday, July 30, 2015

Our final injury prevention installment comes from Aliza, reporting early findings of a piece of research which has investigated patellar tendon development amongst adolescent dancers. 

Jumper's knee is a condition where there is pain just below the knee cap associated with jumping.  The medical term for this condition is "patellar tendinopathy" and it is a fairly common condition in elite dancers, especially those who are strong jumpers and tend to jump a lot.  Jumper's knee is an overuse condition.  The main risk factor for developing symptoms is having pathology within the patellar tendon (pictured below).  It is not clearly understood when pathology can develop in the tendon or when the tendon matures.  

 

A group of researchers from Melbourne are investigating how this tendon changes during adolescence in young ballet students.  The goal of this study is to identify normal and abnormal tendon development.  In order to observe changes in the tendon, this study involves using a 3-D ultrasound device called a UTC (Ultrasound Tissue Characterization) to image the patellar tendons of young ballet students at the Australian Ballet School and the Victorian College of Arts Secondary School throughout puberty.   

This research group will be following the same cohort of students over a two year period to monitor subtle changes in their tendons as they grow and progress through skeletal maturity.  Dancing and other exercise volume is also being closely monitored as well as participation in classes and any injuries.  

The evidence so far has demonstrated that people with pathology in their tendons are at a much higher risk of developing jumper’s knee symptoms.  Researchers have discovered already that after approximately 17 years old, tendons are mature and do not generally turn over new tissue; therefore, if people have pathology within their tendons by this age, it will likely remain within their tendons for life.  This doesn’t mean they will definitely get jumper’s knee symptoms, however they are at a much higher risk than someone with completely healthy tendons.  In younger dancers and athletes (pre-pubertal), the incidence of pathology on their patellar tendons is much more rare and it is thought that perhaps during these pubertal years where adolescents are surpassing their peak height velocity (peak height growth spurt) pathology can develop.  Once we have a better understanding of how tendons mature normally during this time period, we may be able to gain some insight into abnormal tendon maturity.  Throughout this study and in future studies, we hope to gain further understanding of the impact of loading this tendon before it has fully developed and clarify how much jumping is ideal for optimal tendon formation in order to reduce jumper’s knee in dancers and other jumping athletes.

Dancing Longer: Safe and effective dance practice to optimize performance, and minimize injury risk

Posted By Edel Quin on behalf of the IADMS Education Committee, Monday, July 27, 2015

This is the third installment on the topic of dance injury on the IADMS blog. Elsa began by introducing us to injuries and injury management in dance, highlighting some great examples of specialized and tailored injury care for dancers in the UK (National Institute of Dance Medicine and Science) and the USA (Harkness Center for Dance Injury). This was followed up by Stephanie’s post on multi-disciplinary screening programmes as a means of highlighting “any concerns with regards to health, injury risk or mental and physical capabilities” and also the potential role of screening as an educational tool in contributing towards injury prevention. As the next contributor in this series, I focus on minimizing injury risk from the perspective of safe and effective dance principles as applied to dance teaching and dance making.

Dance Science Testing with Wayne McGregor | Random Dance
Dancer: Jessica Wright

Firstly, it is important to dispel the impression that safe dance practice is about ‘wrapping dancers in cotton wool’ to the point that there is no risk, no creativity, no progression. I do not dare to think what dance - a wonderful, expressive, art form - would become if this were the way we engaged with dance teaching and dance making! No – safe dance practice is the complete opposite, it is a means by which dance can continue to challenge physical (and mental) capabilities, through the application of knowledge and understanding of research-informed practice. It is often noted that choreographic practices of today are increasingly demanding of dancers physicality, and at times reach extremes of athleticism. This can be what makes dance exciting! But, how can we continue to push these artistic boundaries, without increasing an already high injury rate1… enter safe and effective practice.

The principles

Safe practice does not solely aim to reduce injury risk, optimizing dancer potential is just as, if not more, important! The combination of these two aims results in the ultimate intention of prolonging participation in dance through healthful practice. The principles are borne out of dance science research, and engage with key overlapping areas of physical, psychological and environmental knowledge (see figure 1 below). Once understood these principles can be applied and adapted to any dance style, any age group, and any dance setting. 


Ask yourself…

As dance leaders (i.e. teacher, choreographer, artistic director, etc.) some of the key safe practice questions we should ask ourselves are:

1. Do I understand and apply physiological principles of warming-up and cooling down to my dance classes/rehearsals? [look out for the upcoming IADMS Resource Paper on Warm-up and Cool-down!]

2. Am I aware of different ways to stretch and when is it best to the different types? [see here]   

3. Do I understand basic anatomical principles and have an awareness of the possible implications of any alignment variations, such as hypermobility or a forward pelvic tilt, within my dancers?  [check out ‘Teaching the Hypermobile Dancer’ by Moira McCormack or ‘Improving Pelvic Alignment’ by Jennifer Deckert]

4. Do I consider the physiological training needs of my dancers (not just the technical or artistic needs)? [see IADMS Resource Paper]  

5. Do I appropriately balance amounts of activity with rest within in dance class/rehearsal3?

6. Do I understand and encourage effective fuelling (nutrition and hydration) in my dancers? [see IADMS Education Committee Resource Paper]

7. Do I know how to manage an injury, if one occurs during my dance session, or how to engage an injured in the dance class? [check out First Aid for Dancers or Technique Class Participation Options for Injured Dancers]

8. Am I aware of how I could create a positive and healthful learning climate in the dance studio?  [check out ‘Standing on the Shoulders of a Young Giant How Dance Teachers Can Benefit From Learning About Positive Psychology’ by Sanna Nordin and Ashley McGill]

9. Do I know how to adapt my safe practice knowledge to my specific dancers and dance style? [see chapter 10 in Quin, Rafferty & Tomlinson (2015)]

If the answer to any of the above is ‘No’ or ‘I’m not sure’, then let today be the day that you take the first step to exploring that specific area of your practice a little more. Dance has evolved, our understanding of the dancing body and mind has evolved, our teaching practices should also continue to evolve.  Keeping up to date with the developments in dance medicine and science research are certainly integral to my own safe and effective dance practice, and that of the dancers that I teach.

While not every dancer or dance teacher has access to the wonderful work of organizations such as the Harkness Center for Dance Injuries in New York or the National Institute of Dance Medicine and Science in the UK, fortunately every dancer, dance teacher, dance leader has access to the growing number of widely available resources, a mere sample of which have been included in this post!  IADMS obviously provides a wide range of easy-to-read research-informed educational resources such as the Resource Papers, the Bulletin for Dancers and Teachers, as well as Posters to adorn dance studio walls. There is also an expanding number of dance-specific texts that are applying the research into practice. There is even an organization dedicated to supporting, developing, encouraging and endorsing safe and healthy dance practice world-wide; Safe in Dance International (SiDI), go here for more.

So, as we strive to advance our art form, let’s do so with the aim of minimizing injury risk, optimizing potential and prolonging participation, by educating ourselves on dance science informed principles. As dance medicine and science research continues to develop, so should our knowledge and application of safe and effective dance practice. Just imagine the possibilities….!

Injury Prevention: Screening as a tool for education

Posted By Posted by Stephanie De’Ath on behalf of the IADMS Education Committee, Tuesday, July 7, 2015

What is screening?

Screening is often used for pre-entry to a school or company to highlight any concerns with regards to health, injury risk or mental and physical capabilities. Although research suggests that protocols should, where possible, be carried out by a physiotherapist or dance science professional there are some protocols that can be adopted by schools or companies with limited resources to at least complete some of the tests for educative purposes.  Although not widely used as an educative tool, screening provides a great opportunity for dancers to learn more about their bodies, optimise performance and identify injury risk1. By addressing the weaknesses or concerns which arise as a result of the screen, a programme of activity can be developed to compliment training and reduce the likelihood of injury. As a member of Trinity Laban's screening team for the past four years, in this post I will explore how screening can contribute to injury prevention from an educational perspective.

 

What is involved in screening?

As highlighted by Liederbach et al2, screening often involves collating information on many components including medical history, skeletal structure, alignment, range of motion, strength, cardio-respiratory response, motor skills, stability and mobility, self esteem, motivation and nutrition amongst others.  From personal experience, the benefits for using screening as an educative tool, rather than pre-entry or for research, is that the methods can be adaptive to reflect the student needs, the current staff's knowledge/experience and developments in research. This can however make it somewhat difficult to use the data for research, which is why changes in protocols should be considered carefully

 

In the UK National Institute of Dance Medicine and Science (NIDMS) screening program, we explore a number of different areas which include: health and injury history, current training exposure, anthropometrics, hypermobility/flexibility, strength, a functional musculoskeletal screen and an aerobic fitness test. Once the assessments have been completed, individuals are invited for feedback to go through each test result: looking at comparable means and discussing how their results can impact their training.

 

How can screening contribute to injury reduction?

There are many benefits and outcomes of screening, however the following are the five testing protocols that I typically find to be most helpful in educating dancers on injury reduction. These protocols can easily be adopted by individuals, especially those with limited resources.

 

1.  Health and injury history

As we already know, results from injury history, menstrual status and nutritional status can be combined to “red flag” symptoms of Female Athlete Triad3. A red flag for each area would be:

- Frequent bone related injuries (more than 2) in the last 12 months e.g. Fractures, bone bruising, etc and/or already diagnosed osteoporosis and/or a known low bone mineral density.

              - Amenorrhea, or no menstrual cycle, for more than three months.

              - And disclosure of, or indicators of, an eating disorder or disordered eating.

There are of course many other areas which may arise as a concern from completing the health and injury questionnaire. For example a low BMI or sleep disturbances, however what is important in this instance is that any red flags for Female Athlete Triad or any other issues are dealt with appropriately. Therefore, if you do not have the provision in your school/ company to provide nutritional advice, have a reliable contact who you can refer your dancers to.

2.  Single jump height

Single jump height measures how high an individual can jump. This result is important information for dancers, however what I find more interesting as an observer of the test is the biomechanics of an individual's jump technique. By looking out for the following we can use the screen itself to optimise the performance of the jump and reduce injury:

             - Are they rolling in or out of the ankles during take-off/landing?

             - Turning in/out of the feet, looking to see if one is more turned out than the other.

             - Are they able to maintain the 90 degree angle at the knees during take-off and
             landing, as specified in the test protocol.

             - If/when fatigued, are they able to maintain technique e.g. feet pointed during
             jump, land in parallel, maintain height, maintain speed, etc

By breaking the jump down and giving this feedback to the dancers I find this to be more helpful than informing them how high/powerful their jump is (of course they will still be interested in this!) as you may point something out to them that hasn’t been identified before.


3. Turnout/turn in

There are a number of different ways to test turnout/ turn in, however I find active standing turnout to be one of the most useful for educative screening, as it is most representational of the dancer in the studio. The dancer will stand on two rotational discs (therefore removing the friction from the floor) and starting in parallel they will turnout or in. The distance of each measurement will be recorded in degrees and repeated three times for accuracy, as they can be rather wobbly if you haven't used them before! In literature it is suggested that dancers should be achieving 70 degrees of turnout4, which may be true for ballet dancers, however for other dance genres this requirement may not be as necessary. What I find that we are actually looking for here is bilateral balance between the right and left side, with no more than 10 degrees difference between the right and left score. An inability to achieve bilateral balance may be an indicator of muscle weakness or tightness in the internal or external rotators or simply a lack of proprioception. I particularly like this test because the dancers are unable to "cheat" due to there being no resistance from the floor - but make sure their knees stay over the toes to ensure no cheating!

4. Plank

Like all of the other tests, the plank is more than just achieving a number, it can be indicative of a number of different physical aspects. However from past experiences we usually see dancers achieving roughly around the 2-3min mark.

Whilst the dancer is completing the plank (feet hip width apart and resting on forearm) you can also look out for the following:

              - Feet: are they rolling in/ out or can they maintain a true parallel?

              - Hips: are they even? Or does one side dip more than the other?

              - Alignment: can they ensure that the head, hips and feet sit in one straight line.

              - Shoulder blades: do they "wing" off the back?

5. Dance Aerobic Fitness Test (DAFT)

Over the past 10 years schools and companies have been able to use Dance Specific Fitness Tests (DSFT)5,6,7. One of the most frequently used DSFT by schools and companies is the contemporary Dance Aerobic Fitness Test (DAFT). This fitness test has a number of advantages beyond the data produced i.e. heart rate and rate of perceived exertion (RPE). Observers can also make notes on the individual’s technique over the five stages, each of which is four minutes and progressively increases in intensity. An observer might look out for: arm placement, landing from the jumps, extension of movements, focus, musicality, coordination, etc. The DAFT stage three is representative of the effort levels required for a technique class and stage five is representative of performance intensity. Therefore, the individual can track the changes in their heart rate and RPE over a time period, to see if their training is providing any positive adaptation in their aerobic fitness levels and resistance to fatigue, which allow them to perform set movement at a lower relative intensity. There is currently no published data available on the norms or averages for each stage of the DAFT, however Redding et al will be presenting this information for the first time at the 25th Annual meeting in Pittsburgh…so watch this space!

 

So…what do we do with all this information?

Well, as you can see from the above information, the outcomes are primarily indicators of an area of weakness. To allow this information to contribute to injury reduction we need to ensure that we apply these findings back into training. Therefore, I would recommend that your feedback time is highlighted as one of the most important features of your educative screening session. These indicators cannot be actioned if dancers do not understand the importance and relevance of the results, and furthermore, how to implement this into their training. Ensure you are confident with the official protocols for each test and most importantly, develop a network of dance specialist professionals who you trust for onward referral.

Alignment of the leg and its impact on the dancer's knee: Clips from the 2014 Annual Meeting

Posted By Liane Simmel, Tuesday, June 9, 2015

IADMS Simmel from Steven Karageanes on Vimeo.

This presentation gives an insight into the functional anatomy of the dancer’s knee, its biomechanical prerequisites and its economic use as base for a high resilience to dance injuries.

 

Over the last decade as more and more acrobatic movements invaded the various dance styles, the strain on the dancer’s knees has largely increased. Training on hard, inappropriate floors or dancing choreographies in high heels can add even more problems. Pirouettes on the knees, knee drops, and even a plié in fourth position require particular leg stability and optimal mobility in the knee. But dancers often pay little attention to their knees. They are seldom specifically warmed up, directly trained or used consciously in everyday life. Nonetheless, their functionality is a top priority if dancers’ knees are to be kept fit and healthy.

Being the largest joint of the body, the knee works as an important coordination centre to the leg. Located between the hip joint above and the foot below, it reacts to all movements and positions of these, its two functional partners. With its high number of daily repetitions, even seemingly small dance technical pitfalls like rolling onto the inner side of the foot in the turned out position or losing the alignment of the leg in demi plié  can lead to overuse problems and even acute injuries in the knee area.

As dancers are accustomed to work precisely on their coordination and alignment they do have a big supply of tools for improving leg alignment, be it in the dance class or in everyday life. They just have to be made aware of this potential...

When analyzing leg alignment and knee load in a dancer, there is more to consider than just screening the bony and functional anatomy of the lower extremity itself. When it comes to assessing the stress and load on the dancer’s knee, the form and mobility of the foot, the bony and muscular situation of the hip joint, the position and mobility of the pelvis as well as the torsion of the tibia play an important role. Thus, to get an impression about the dancer’s anatomical prerequisites, screening should start by analysing the anatomy of the whole functional chain: the foot, the torsion of the tibia, the antetorsion angle in the hip joint and the position and mobility of the pelvic girdle. To detect the keystones by which the dancer can influence, change and improve his or her individual biomechanics the next step in line is to assess the flexibility, function and muscular strength of all functional partners – foot, hip joint, pelvis and last but not least the knee itself.  

Being the most common challenges in many of the different dance styles, turnout, plié and hyperextended legs have been chosen to explain the approach of biomechanical awareness training in dance. Dancers spend a great deal of their days in the studio, but there is still a life outside the ballet room, and movements and biomechanics outside the studio seem to have potential for improvement in many dancers. Therefore the habits in the dancer’s everyday life movement should thoroughly be analysed and searched for negative influence on body functionality by imprinting unhealthy movement patterns in the dancer’s neurological motor program. If not detected and changed these often unconscious habits will be trained on a regular daily basis, imprinting into the dancers motion cortex. To break them up, specific exercises should be performed, with the focus on (1) mobilization (to allow new movement possibilities), (2) awareness (to make unhealthy movement patterns conscious and consider possible changes), (3) strengthening (to enable the muscles and the neurological system to perform unfamiliar movements) and (4) relaxation (to reduce unnecessary muscles tension and soft tissue restrictions). With “one second exercises” performed numerous times per day, the reset of the neurological motor program gets started.

Finally, what seems for the majority of the dancers the most challenging step, the new movement potential have to be transferred back from everyday life to the studio, to the individual dance technique. Easily understandable anatomical and biomechanical images and movement cues can support this tricky step. And last but not least: patience.
