“…1,9 The findings from our study were comparable to these values. The small absolute difference of less than 3°in passive hip ER ROM we found between sides may not be clinically important and is probably unlikely to affect performance.…”

“…1,2,5,7,9,10,13 Measured ROM can be expected to vary according to the testing position (supine, prone, sitting, or standing), the degree of hip flexion/extension, the testing of active versus passive ROM, the degree of stabilization and positioning of the pelvis, and the position of the contralateral limb. In addition, the dancer's gender, age, and level of training (novice, preprofessional, or professional) will also have an effect.…”

Study Design: Descriptive correlational study. Objectives: To determine relationships between aspects of turnout and injury history in preprofessional classical ballet dancers, and to determine the clinical utility of various methods used to assess turnout. Background: In Australia 50% of professional dancers currently have persistent or recurrent injuries, with 36% of these injuries commencing before 18 years of age (preprofessional level). Overuse or nontraumatic dance injuries are often attributed to faults in technique, with poor turnout and inappropriate compensatory strategies consistently cited as the main cause. Methods and Measures: Twenty-nine dancers (24 female), aged 15 to 22 years, were recruited from a preprofessional classical ballet program. Measurements were taken of passive and active hip external rotation (ER) range of motion (ROM) in supine, and functional turnout angles in standing. Three turnout variables were derived: active ER lag, compensated turnout, and static-dynamic turnout difference. Injury history over the previous 2 years was ascertained by interview. Pearson product moment and Spearman rank correlation coefficients were used to determine associations between turnout variables and injury history. Results: All dancers reported a history of injury, with 93.1% reporting a history of nontraumatic injuries and 41.4% reporting a history of traumatic injuries. Number and severity of nontraumatic injuries were associated with reduced functional turnout (r or rho Ͼ 0.38; P Ͻ .04), but not with hip ER ROM. Number and severity of traumatic injuries were not associated with turnout. No correlation was found between hip ER ROM and functional turnout. Conclusions: Functional measures of turnout are more relevant than hip ER ROM to prevalence of nontraumatic dance injuries. Control of turnout in classical ballet dancers should be assessed dynamically and in functional positions. J Orthop Sports Phys Ther 2005;35:307-318.

“…6 According to Thomasen,24 dancers ideally achieve 180°of turnout by externally rotating the hips 70°u nilaterally, externally rotating the tibiae 5°unilater-ally, and externally rotating the feet 15°unilaterally, thereby adding up to 180°of bilateral turnout. Although some dancers do have unilateral hip external rotation ranges of motion exceeding 70°and can achieve ideal turnout with relative ease, numerous studies 1,3,6,8,10,12 have reported significantly lower values (between 39.7°and 52.0°) for the amount of passive hip external rotation in the typical ballet dancer.…”

Study Design: Retrospective cohort study. Objectives: To compare the relationship between the degrees of turnout, passive hip external rotation range of motion, and self-reported history of low back and lower extremity injury in ballet dancers. Background: Ballet dancers are encouraged to externally rotate their lower extremities (turnout) as far as possible. This may cause stress on the dancers' low back and lower extremities, putting them at risk for injury. Methods and Measures: Thirty college-level ballet dancers and instructors were evaluated. Each participant completed an injury questionnaire that placed the participant either in a group with a self-reported history of low back and lower extremity injury or in a group without a self-reported history of low back and lower extremity injury. Each dancer's first-position turnout and passive external rotation range of motion for both hips were measured. The comparison between each dancer's first-position turnout and the measured hip external rotation range of motion was called ''compensated turnout.'' A 2-sample t test was used to determine if the average compensated turnout was significantly different in the injured and noninjured groups. Key Words: dancing, hip rotation, injuryA lthough ballet is noted for its beauty and grace by audiences, it can be a source of injury and pain for dancers. Epidemiological studies of ballet dancers show that 90% of professional dancers and 63% of student dancers have had a dance-related injury at some point in their ballet career. 18 In a study by Lewis et al, 13 100% of the retired dancers reported at least 1 injury during their career. This high incidence of ballet-related injury was confirmed in a major American ballet company, where ''there was an 80% chance of a dancer's filing for worker's compensation for physical disability during a single season. '' 18 A report of the New York City Ballet indicated that on any given day during the contract season, 17% of the dancers were not dancing because of injury. 18 Of these injuries, 60% to 80% involved the knee, ankle, or foot.18 While ballet dancers may appear to dance with ease, ballet is physically demanding, taxing, and potentially injurious.

“…While some recommend the use of measurement protocols that include all the lower limb to assess the individual participation rate of each segment and joint [20][21][22] , others defend the use of measurements that simulate functional dance movements, based on the assumption that those measures will be more useful for doctors, teachers, and the dancers themselves 1,[23][24][25] . This discrepancy suggests there is no consensus on which protocol to follow in the turnout evaluation.…”

Métodos usados para avaliar o en dehors ou turnout de dançarinos e bailarinos clássicos: revisão da literatura

et al. 2017

RESUMO A técnica do ballet clássico exige a realização máxima do en dehors ou turnout, caracterizado pela rotação externa de membros inferiores. Considerando a sua importância, diversos protocolos para a sua avaliação e mensuração têm sido propostos. O objetivo desta revisão foi investigar sistematicamente quais os métodos utilizados para avaliar o turnout de bailarinos clássicos e/ou praticantes de ballet clássico existentes atualmente. A busca foi feita nas bases de dados Scopus, Science Direct e PubMed, no mês de fevereiro de 2016, e os artigos encontrados deveriam: estar redigidos na língua inglesa, avaliar bailarinos clássicos ou dançarinos que praticassem ballet clássico e mensurar o en dehors ou turnout. Foram encontrados 593 artigos, dos quais 25 foram pré-selecionados para esta revisão, apresentando quinze diferentes métodos e instrumentos de mensuração do turnout: cinemetria; inclinômetro; turnout protactor ou transferidor para medir o turnout; goniômetro; Dupuis Tropometer; transferidor original; fotos dos sujeitos; discos rotacionais; teste de flexibilidade de Nicholas; flexímetro; desenho clínico dos pés; sujeito sobre um pedaço de papel ou solo ou quadro branco; ressonância magnética; filmagem do sujeito executando sequência de passos; Dasco Pro Angle Finder. Esta revisão apresenta forte evidência para afirmar que não há, até o presente momento, um método ou instrumento padrão-ouro para mensuração do turnout de bailarinos, de modo que esta costuma ser adaptada e escolhida de acordo com o objetivo de cada estudo.
