Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function...

Hypermobility may be associated with decreased lower extremity proprioception, which in turn may increase injury risk. The prevalence of hypermobility in dancers varies across studies, but joint hypermobility appears to be more common in dancers than in the general population. The purpose of this study was to determine how hypermobility affects eyes-closed single-limb balance as an indirect measure of proprioception in dancers. The secondary aim was to compare hypermobility and balance across dancer affiliation groups...

Courtship behaviours, frequent among modern insects, have left extremely rare fossil traces. None are known previously for fossil odonatans. Fossil traces of such behaviours are better known among the vertebrates, e.g. the hypertelic antlers of the Pleistocene giant deer Megaloceros giganteus. Here we describe spectacular extremely expanded, pod-like tibiae in males of a platycnemidid damselfly from mid-Cretaceous Burmese amber. Such structures in modern damselflies, help to fend off other suitors as well as attract mating females, increasing the chances of successful mating...

This article discusses the ways in which artists have incorporated or failed to incorporate the aging process of their bodies into their art. Using Russian ballet dancer Mikhail Baryshnikov and the French painter Claude Monet as cases in point, we explore situations in which physical changes brought about by aging compromises artists' ability to engage with their artistic medium. Connecting Monet's oeuvre and Baryshnikov's dance performances to life writing accounts, we draw on John Paul Eakin's concept of "living autobiographically": In this vein, life writing research does not only have to take into account concepts of identity as they emerge from life writing narratives, but it also needs to explore the somatic, corporeal and material dimensions of these narratives...

There is ongoing debate about how to define injury in dance: the most encompassing one or a time-loss definition. We examined the relationship between touring, performance schedule and injury definition on injury rates in a professional modern dance company over one-year. In-house healthcare management tracked 35 dancers for work-related musculoskeletal injuries (WMSI), time-loss injuries (TLinj), complaints, and exposure. The year was divided into 6 segments to allow comparison of effects of performance, rehearsal, and touring...

Art is a product of human creativity; it is a superior skill that can be learned by study, practice and observation. Modern neuroscience and neuroimaging enable study of the processes during artistic performance. Creative people have less marked hemispheric dominance. It was found that the right hemisphere is specialized for metaphoric thinking, playfulness, solution finding and synthesizing, it is the center of visualization, imagination and conceptualization, but the left hemisphere is still needed for artistic work to achieve balance...

Clinical research has shown the mental health benefits of dance practice. This has become a significant subject of inquiry in psychotherapeutic settings for the elderly and adolescents. However, the relationship between dance practice and correlates of psychological well-being, such as mindfulness and life satisfaction (LS)-two relevant indicators of mental health, has been explored relatively little in young women. The present study contrasted mindfulness and LS in young women (n = 81) who practiced dance regularly in three modern dance schools in the Province of Barcelona with a control group of non-practitioners (n = 120) studying at a university in Barcelona...

This study describes trends in mean standing functional turnout angles measured on a floor protractor (FP) and the Functional Footprint(®) rotational instrument (RI) during routine clinical screens. Twenty-three professional ballet dancers, 26 collegiate modern students, and 46 ballet academy dancers participated in the study. All dancers demonstrated greater total turnout on the FP compared to the RI (p < 0.001), and the collegiate dancers had significantly smaller total turnout angles compared to both of the other groups (p < 0...

In brief: Modern dance encompasses many different techniques, each of which makes unique demands on the dancer's body. When these demands are amplified by the repetition required to learn and use any technique, overuse injuries sometimes result. To provide a data base for studying injuries in a significant sample of the modern dance community, we surveyed 164 modern dancers, who reported a total of 229 injuries over the past five years. Injury sites and frequency varied with the dance technique. For example, the rate of knee injuries was higher among dancers using the Graham technique than among those using the Horton technique (25% and 10...

In brief: A physiologic profile comparing 39 female dancers was undertaken to better understand the factors distinguishing four levels and styles of dance: professional ballet (PB), professional modern, university ballet, and university modern. The PB dancers had significantly lower VO2 max values on the tread-mill as well as lower peak blood lactate levels following the Wingate test for anaerobic capacity than the other dancers. The PB dancers also had a significantly higher isokinetic hamstring-quadriceps ratio than the modern dancers...

OBJECTIVE: To study dancers' perceptions of the physical, cognitive, affective, and social benefits of partnered dancing. METHOD: 225 dancers (71% female) were recruited through a community ballroom dance center and completed an online survey designed to measure their perceptions of the physical, cognitive, affective, and social benefits of modern, partnered dance styles (swing, Lindy Hop, and ballroom dancing). Subgroups were formed for analyses. For one set of analyses, groups based on length of dance participation were formed: experienced (dancing for more than 2 years) or novice (dancing for less than a year) dancers...

The aerobic demands of today's dance repertoire warrant understanding of the current cardiorespiratory fitness of dancers. The purpose of this study was to compare aerobic fitness levels of professional and pre-professional modern dancers and determine change over time. A retrospective analysis of four groups, two professional, and two pre-professional, was conducted in preseason annual screens, occurring before the professional dancers' rehearsal period and the students' academic training. Resting (HRrest), peak (HRpeak), and recovery (HRrecov) heart rate, and blood pressure (BP) were compared in 577 dancers, using an accelerated 3-minute step test...

The influence of positive selection sweeps in human evolution is increasingly debated, although our ability to detect them is hampered by inherent uncertainties in the timing of past events. Ancient genomes provide snapshots of allele frequencies in the past and can help address this question. We combine modern and ancient genomic data in a simple statistic (DAnc) to time allele frequency changes, and investigate the role of drift and adaptation in population differentiation. Only 30% of the most strongly differentiated alleles between Africans and Eurasians changed in frequency during the colonization of Eurasia, but in Europe these alleles are enriched in genic and putatively functional alleles to an extent only compatible with local adaptation...

Dance is a non-pharmacological intervention that helps maintain functional independence and quality of life in people with Parkinson's disease (PPD). Results from controlled studies on group-delivered dance for people with mild-to-moderate stage Parkinson's have shown statistically and clinically significant improvements in gait, balance, and psychosocial factors. Tested interventions include non-partnered dance forms (ballet and modern dance) and partnered (tango). In all of these dance forms, specific movement patterns initially are learned through repetition and performed in time-to-music...

Biologically active but floppy proteins represent a new reality of modern protein science. These intrinsically disordered proteins (IDPs) and hybrid proteins containing ordered and intrinsically disordered protein regions (IDPRs) constitute a noticeable part of any given proteome. Functionally, they complement ordered proteins, and their conformational flexibility and structural plasticity allow them to perform impossible tricks and be engaged in biological activities that are inaccessible to well folded proteins with their unique structures...

STUDY DESIGN: Case report. BACKGROUND: Professional ballet and modern dancers spend an inordinate amount of time on demi pointe (rising onto their forefeet), placing excessive force on the metatarsophalangeal joints and putting them at risk of instability. Surgical treatment of this condition is well described in the literature. However, studies describing conservative management, particularly in dance populations, are lacking. CASE DESCRIPTION: A 33-year-old dancer presented with insidious onset of medial arch and second and third metatarsophalangeal joint pain...

Ankle injuries are the most common lower extremity injury in dance and sports, often resulting in limitation of dorsiflexion or plantar flexion. Accurate assessment of any limitation in range of motion is an important factor in implementing effective preventative and rehabilitative regimens. Ankle range of motion has traditionally been quantified with goniometers. However, standard goniometry may not be an adequate method of assessing plantar flexion range of motion in dancers. An alternative technique using inclinometers to quantify ankle plantar flexion has been reported, but reliability and inter-instrument correlations for this method are limited...
