Abstract
INTRODUCTION Dancers generally begin training in a variety of styles at a young age. Across ages and levels of participation, dancers are at high risk for injury. Most available injury surveillance tools, however, have been developed for adult populations. Valid, reliable tools that monitor injury and exposure of pre-adolescent dance populations are limited. Therefore, the purpose of this study was to determine the validity and reliability of a dance injury and participation questionnaire specifically for pre-adolescent private studio dancers. METHODS Four stages of validity and reliability testing assessed a novel questionnaire: initial design based on previous literature, expert panel review, cognitive interviews, and test-retest reliability. The target population was 8 to 12-year-olds who participate in at least 1 class/week at a private studio. Feedback from a panel review and cognitive interviews was incorporated. Test-retest analyses included Cohen's kappa coefficients and percent agreement for categorical variables, and intraclass correlation coefficients [ICCs (3,1)], absolute mean difference (md) and Pearson's correlation coefficients (r) for numerical data. RESULTS The final questionnaire was comprised of 4 sections: demographics, dance training history, current dance participation (previous 1-year and 4-months), and dance-related injury history (previous 1-year and 4-months). Items with categorical responses estimated kappa coefficients from 0.32 to 1.00, and percent agreement between 81% and 100%. For items with numeric responses, ICC estimates ranged between .14 and 1.00, r values between .14 and 1.00, and the largest absolute md was 0.46. The 4-month recall sections revealed higher agreement than the 1-year sections. CONCLUSION This valid pre-adolescent dance injury and participation questionnaire demonstrates good to excellent reliability across all items. To support participant completions, assistance from a parent/guardian is suggested. To move dance epidemiology research forward among private studio dancers aged 8 to 12 years, employment of this questionnaire is therefore recommended.

Abstract
OBJECTIVES Describe the epidemiology of dance-related musculoskeletal injury leading to forced time-loss in elite pre-professional dancers and provide descriptive data on the prevalence concerning diagnoses, location, and injury type, stratified by gender and skill level. METHODS Retrospective cohort, over a 3-year period on a full-time pre-professional Portuguese dance school featuring 70 both gender students with a mean age of 14.87 years. A total of 110 injuries were analyzed. Non-parametric statistics were used. RESULTS The most prevalent diagnosis leading to forced time-loss in female dancers were Medial Tibial Stress Syndrome (MTSS), 14.29%, and Posterior Ankle Impingement Syndrome (PAIS), 7.14%, whereas in male dancers these were Hallux Sprain, 17.50%, and Lumbar Spine Joint Injuries, 7.50%. Differences were found in injuries' anatomical location between genders and in Incidence Proportion and Clinical Incidence between skill levels. 72.20% of the chronic injuries and 50.00% of the acute injuries occurred in Level III students. CONCLUSIONS With respect to forced time-loss injuries, male dancers were found to sustain more acute traumatic injuries and female dancers overuse, respectively, sprains and MTSS and PAIS. Identifying which injuries are most likely to lead to forced time-loss may be useful for helping health-care professionals in clinical decision-making and in developing more effective injury prevention and management strategies.

Abstract
OBJECTIVE Pediatric injuries in performance sports represent a significant healthcare burden and account for over 50,000 annual Emergency Department (ED) visits in the United States. The objective of this study was to characterize and compare pediatric injury presentation across the most common performance sports. METHODS The National Electronic Injury Surveillance System (NEISS) database was retrospectively analyzed for pediatric injuries (3-18 years) related to gymnastics, dance, or cheerleading from 2015-2019. Cases were categorized as children (˂11 years) or adolescent (≥11 years). Injuries were categorized as orthopedic (fractures, dislocations, sprain, strains), non-orthopedic (contusion, internal injury, laceration), concussion, or other/unknown. Case narratives were used to categorize mechanism of injury as contact or non-contact. Appropriate sample NEISS weights estimation was applied for statistical analysis and Confidence Intervals (CI). RESULTS A total of 393,110 injuries were observed over the five-year study period, with a mean of 78,622 annual injuries. Gymnastics, dance, and cheerleading accounted for 136,422 injuries, 96,416 injuries, and 160,272 injuries, respectively. Most cases were adolescent (71%; 95% CI: 68-74%) and occurred in a sports-related setting (65%, 95% CI: 57-72%). Gymnastics had the highest proportion of injuries among children (50%) as compared to dancers (25%) or cheerleaders (12%) (p < 0.01). Non-contact injuries most affected the lower extremity (43-68%) and resulted in an orthopedic diagnosis (63-71%), and contact injuries had a higher proportion of injuries affecting the head, neck, and face (29-51%) and non-orthopedic diagnoses (29-38%). Gymnastics had the most upper extremity non-contact injuries (42%) and dance the most lower extremity non-contact injuries (68%) (p < 0.01). Cheerleading had the highest incidence of overall concussions (8%), contact injuries (47%), and concussions due to contact injury (15%). CONCLUSION Pediatric gymnasts, cheerleaders, and dancers have important similarities and differences in injury pattern which may lead to the development of sport-specific injury prevention programs for pediatric performance athletes.

Abstract
BACKGROUND Dancers possess a large degree of hip range of motion that results from a combination of innate and acquired osseous morphology and permissive soft tissues. Generalized hypermobility in dancers may predispose them to a spectrum of hip instability. The objective of this narrative review is to discuss the anatomical characteristics, pathogenesis, risk factors, clinical signs and symptoms, management, and outcomes of hip instability treatments in dancers. METHODS A retrospective search was performed beginning November 1, 2017, for English language articles regarding hip stability in the dancer. Key words used included but were not limited to: dance(r), ballet, hip, hypermobility, range of motion, instability, microinstability, and laxity. PubMed, Scopus, and MEDLINE databases were used. RESULTS Forty-three studies were analyzed. Groin pain was found to be the most common presenting symptom of hip instability. A variety of impingement and instability signs may be elicited during physical examination. Hypermobility is frequently observed and is thought to be a necessity for participation in elite levels of ballet. Radiographs and advanced planar imaging (magnetic resonance imaging and computed tomography) should be scrutinized to evaluate for dysplasia, cam, pincer, subspine, and rotational morphologies. Dysplasia (low volume acetabulum), cam morphology, femoral retroversion, and coxa valga are common findings in the ballet dancers' hip. Labral injuries and ligamentum teres tears are common and may potentiate instability in the hip. Management options include education, oral non-opioid medications, activity modification, exercise prescription, and surgery. Reported outcomes of these treatments in ballet are limited. CONCLUSION Hip hypermobility is prevalent in the ballet population and is a clear advantage. However, it may increase the risk of instability. It is important to identify the multifactorial osseous and soft tissue etiology of hip or groin pain in dancers. Practitioners should have a high level of suspicion for hip instability in the dancer presenting with hip pain and treat accordingly. There is a significant need for increased quantity and quality of investigation into the outcomes of treatment for hip instability in the dancer.

Abstract
BACKGROUND Ballet dancers have a high prevalence of injuries to the lower extremity. Many studies have investigated the relationship between dance injury and risk factors. However, risk factors for lower-extremity injury comparing recreational- and elite-level ballet dancers are scarce. OBJECTIVE To systematically review available original studies to assess risk factors for lower-extremity injury in female ballet dancers between recreational and elite ballet dancers. DATA SOURCES Five online databases [Web of Science, PubMed, OVID (Medline), EBSCO, and ProQuest] were searched systematically. STUDY SELECTION Included studies had an analytic study design published in the past 11 years and investigated an association between potential risk factors and lower-extremity injury in female ballet dancers. STUDY APPRAISAL Assessed independently by 2 reviewers using the Downs and Black (DB) criteria and Oxford Centre of Evidence-Based Medicine. RESULTS Seventeen studies were included. Alignment was a risk factor for lower-extremity injury in both recreational and elite ballet dancers. In elite ballet dancers, poor lumbopelvic movement control, inappropriate transversus abdominis contraction, decreased lower-extremity strength, and poor aerobic fitness were risk factors for lower-extremity injury. In recreational ballet dancers, hypermobility of the hip and ankle and longer training hours were risk factors for lower-extremity injury. Mean DB score was 15.94 (SD 1.57). The majority of studies were retrospective cohort studies or had poor follow-up, with 7 level 2b studies, 6 level 3b studies (cross-sectional), and 4 level 1b studies (prospective cohort with good follow-up). CONCLUSIONS Alignment was identified as a common risk factor for recreational and elite ballet dancers. Other risk factors differed between recreational ballet dancers and elite ballet dancers. Future studies are warranted to use a prospective study design, identify dance level-specific risk factors, and implement evidence-based prevention strategies.

Abstract
Care of young dancers requires a unique approach during a critical time of growth and development. Young dancers' well-being depends on factors including sleep, mental health, growth-associated musculoskeletal imbalances, and nutrition. Puberty is a particularly important time for young dancers. It coincides with an increased commitment to their art form and physical/psychosocial changes. It is imperative for practitioners to understand these various factors in order to optimize young dancers' health and allow them to safely train and perform.

Abstract
BACKGROUND Since ballet dancers begin their training before skeletal maturity, accurate and non-invasive identification of cartilage diseases is clinically important. Angle-dependent analysis of T1rho and T2 sequences can be useful for quantification of the composition of cartilage. PURPOSE To investigate the angle-dependent T1rho and T2 profiles of ankle cartilage in non-dancers and dancers. MATERIAL AND METHODS Ten female non-dancers, ten female dancers, and 9 male dancers were evaluated using T1rho and T2 mapping sequences. Manual segmentation of talar and tibial cartilage on these images was performed by two radiologists. Inter- and intra-rater reliabilities were calculated using intraclass correlation coefficients (ICCs) and Bland-Altman analysis. Mean thickness and volume of cartilage were estimated. Angle-dependent relaxation time profiles of talar and tibial cartilage were created. RESULTS ICCs of the number of segmented pixels were poor to excellent. Bland-Altman plots indicated that differences were associated with segment sizes. Segmented cartilage on T1rho demonstrated larger thickness and volume than those on T2 in all populations. Male dancers showed larger cartilage thickness and volume than female dancers and non-dancers. Each cartilage demonstrated angular-dependent T1rho and T2 profiles. Minimal T1rho and T2 values were observed at approximately 180°-200°; higher values were seen at the angle closer to the magic angle. Minimal T2 value of talar cartilage of dancers was larger than that of non-dancers. CONCLUSION In this small cohort study, regional and sex variations of ankle cartilage T1rho and T2 values in dancers and non-dancers were demonstrated using an angle-dependent approach.

Abstract
Musculoskeletal pain is a common cause of pain in adolescence and can be an important predictor of future pain. The prevalence of hip or groin pain that could potentially affect different adolescent populations has not yet been systematically reviewed. This systematic review aimed to determine the prevalence of hip or groin pain in this population. Five electronic databases were searched until January 2019 for eligible studies that included males and females 13 to 19 years of age. Study selection, data extraction, and risk of bias assessments were completed by 2 independent researchers. Based on inclusion criteria, 8 population-based, 8 clinical, and 4 sports populations were included. Studies were conducted in Europe, North America, and Australia. The prevalence was dichotomized into "0 to 3 months" and "3 months and above." Meta-analyses were performed to estimate the prevalence from 0 to 3 months, and individual estimates were reported for studies of 3 months and above. The overall prevalence of hip or groin pain in all adolescents from 0 to 3 months was 12% (95% confidence interval [CI] 6%, 23%) based on 10 studies, and was 7% (95% CI 6%, 10%) based on 7 population studies. Caution should be applied to these estimates due to substantial study heterogeneity. The pain prevalence in cerebral palsy from 0 to 3 months based on 4 studies was 13% (95% CI 10%, 15%). Individual prevalence estimates were 6% and 31% in obese and 4% in hypermobility populations, respectively, and ranged from 6% to 100% in 4 sports studies. The validity of these estimates is compromised by poor methodological quality.

Abstract
Low back pain is one of the most prevalent complaints of athletes at all levels of competition. The purpose of this literature review is to provide an overview of sport-specific injuries and treatment outcomes that can be used by healthcare providers to better recognize injury patterns and treatment options for different groups of athletes. To our knowledge, no prior comprehensive review of lumbar spine injuries in sports is currently available in the literature, and it is essential that healthcare providers understand the sport-specific injury patterns and treatment guidelines for athletes presenting with low back pain following an athletic injury. Injury mechanisms were found to vary significantly by sport, although some broad recommendations can be made with regards to optimal treatment for these injuries and return to play. Additionally, it was found that certain treatments were more beneficial and resulted in higher rates of return to play depending on the specific sport of the injured athlete. Healthcare providers need to be aware of the different injury patterns seen in specific sports in order to properly evaluate and treat these injuries. Furthermore, an individualized treatment plan needs to be selected in a sport-specific context in order to meet the needs of the athlete in the short and long term.

Abstract
BACKGROUND Dance is a physical pursuit that involves loading the spine through repetitive dynamic movements and lifting tasks. As such, low back pain (LBP) and low back injury (LBI) have been identified as common health problems in contemporary and classical ballet dancers. However, clarity regarding the experience of LBP and LBI in dance is lacking. OBJECTIVES To systematically review and synthesize the epidemiology of LBP and LBI in dance populations. METHODS A comprehensive search of 6 electronic databases, back catalogs of dance science-specific journals, and reference lists of relevant articles and a forward citation search were performed. RESULTS Fifty full-text articles were included in the final systematic review. There was considerable methodological heterogeneity among the included studies. The median (range) point, yearly, and lifetime prevalence of LBP was 27% (17%-39%), 73% (41%-82%), and 50% (17%-88%), respectively. The lower back contributed to 11% (4%-22%) of time loss and 11% (5%-23%) of medical-attention injuries. CONCLUSION Dancers are vulnerable to LBP and LBI. The use of definitions that are sensitive to the complexity of LBP and LBI would facilitate improved understanding of the problem within dance, inform health care strategies, and allow for monitoring LBP-specific intervention outcomes.

Abstract
INTRODUCTION preprofessional dance training starts at very early ages, on a highly demanding environment placing students at significant risk for injury. Injury management and prevention are a matter of concern. Given the constant interchangeability of risk factors, identifying injury patterns may prove to be equally as important. Data looking back from the time of injury through context-specific approaches are missing. OBJECTIVES To identify activity-related injury patterns based on prediagnostic data. METHODS Prospective, non-randomized, observational study, over a 3 years period on a full-time preprofessional dance school featuring both gender students aged 9-21 years old. Non-parametric statistics were used. RESULTS A total of 625 dance injury records from 209 students, n = 68 males and n = 141 females, were analyzed. Season injury risk probability was identified, proving different for each skill level (SkL). Multiple individual injuries revealed a trend toward prevalence rates in advanced level, while index injuries incidence becomes more noticeable in entry level students. Overall incidence rates had no significant differences within SkL. Anatomical location was in line with previous research, although differences were found between gender and SkL. Most injuries occurred in classes, with jumps standing out as the main motor action associated with injury symptoms of gradual onset mechanism. CONCLUSION Dance injuries happen because of dance practice. Knowing the context of injury history from the injured dancer perspective is determinant for management and prevention. prediagnostic data are an umbrella term encompassing several aspects of injury background and represents fertile ground for research. Context-specific methodological approaches are recommended.

Abstract
Study Design Cohort study. Background Multiple operational definitions of injury exist in dance research. The influence that these different injury definitions have on epidemiological estimations of injury burden among dancers warrants investigation. Objective To describe the influence of injury definition on injury prevalence, incidence, and severity in preprofessional ballet and contemporary dancers. Methods Dancers registered in full-time preprofessional ballet (n = 85; 77 female; median age, 15 years; range, 11-19 years) and contemporary (n = 60; 58 female; median age, 19 years; range, 17-30 years) training completed weekly online questionnaires (modified Oslo Sports Trauma Research Centre questionnaire on health problems) using 3 injury definitions: (1) time loss (unable to complete 1 or more classes/rehearsals/performances for 1 or more days beyond onset), (2) medical attention, and (3) any complaint. Physical therapists completed injury report forms to capture dance-related medical attention and time-loss injuries. Percent agreement between injury registration methods was estimated. Injury prevalence (seasonal proportion of dancers injured), incidence rates (count of new injuries per 1000 dance-exposure hours), and severity (total days lost) were examined across each definition, registration method, and dance style. Results Questionnaire response rate was 99%. Agreement between registration methods ranged between 59% (time loss) and 74% (injury location). Depending on definition, registration, and dance style, injury prevalence ranged between 9.4% (95% confidence interval [CI]: 4.1%, 17.7%; time loss) and 82.4% (95% CI: 72.5%, 89.8%; any complaint), incidence rates between 0.1 (95% CI: 0.03, 0.2; time loss) and 4.9 (95% CI: 4.1, 5.8; any complaint) injuries per 1000 dance-hours, and days lost between 111 and 588 days. Conclusion Time-loss and medical-attention injury definitions underestimate the injury burden in preprofessional dancers. Accordingly, injury surveillance methodologies should consider more inclusive injury definitions. J Orthop Sports Phys Ther 2018;48(3):185-193.

Abstract
OBJECTIVES To identify whether a physical examination for patello-femoral pain (PFP) is related to ultrasonography findings at the knee, and to identify possible factors related to PFP in young dancers. METHODS Sixty-seven young female dancers (7th grade, aged 12.8 ± 0.5) from three schools with identical special dance programs were included in the study. All the dancers were interviewed for demographic details, dance background, and training intensity; were evaluated for anthropometric measurements; underwent physical examination of both knees for PFP and for knee range of motion (ROM); and, had ultrasonography assessment for pathologies and of anatomical parts of their knees. RESULTS PFP was found in 54.5% of the 134 knees physically examined. In ultrasonography assessment, infra-articular effusion was found in 46.2% of the knees examined. H/week of dance practice was significantly higher among dancers with PFP (in both knees) compared with dancers with no PFP (p < .05). Knees with PFP had a significantly higher prevalence of intra articular effusion (p = .018) and higher prevalence of genu-recurvatum (p = .042). Knees with PFP had significantly greater growth plate width-anterior tibial tuberosity (p = .022) and a greater bony trochlear groove angle (p = .048). CONCLUSION This study describes the relationship between physical examination for PFP and the sonographic findings, and the factors related to knee injuries. The results showed a high prevalence of PFP and intra articular knee effusion among young dancers at the age of 12-13 years; and, that the number of hours of practice and anatomical structure are related to PFP. Our results should alert physicians, physiotherapists, athletic trainers and dance teachers to the need for devising modifications of training and injury prevention strategies from a young age (<12 years old).

Abstract
OBJECTIVE To identify (1) the predominant level of evidence of the clinical studies regarding the hip pathology, risk factors, treatment, and clinical outcomes in artistic athletes (dancers, figure skaters, and gymnasts) (2) the most commonly reported hip pathology, risk factors, treatments, and clinical outcomes in dancers, figure skaters, and gymnasts. METHODS To conduct this systematic review PubMed, EMBASE, and Scopus databases were searched for relevant studies and pertinent data were collected from the eligible articles. Included were studies which reported hip injuries in artistic athletes, the risk factors, treatment, and/or the clinical outcomes. We excluded case reports or irrelevant studies. No meta-analysis was performed because of study heterogeneity. The methodical index for nonrandomized studies (MINORS) criteria were used for quality control. MAIN RESULTS Thirty-eight studies were included in the analysis. The mean MINORS score was 13.6 ± 4.6 points indicating fair quality of evidence of the included articles. The predominant level of evidence was level IV. Chondrolabral pathology and muscle injuries were the most commonly reported pathologies. We found only 2 risk factor analysis studies; however, many studies reported risk correlation between artistic sports or imaging findings and hip pathology. Treatment strategies were reported in only 7 studies, clinical outcomes are significantly underreported. CONCLUSION Chondrolabral pathology was the most commonly reported hip pathology in artistic athletes, however, prospective cohort studies are necessary to really understand these injuries and their associated risk factors. The lack of clinical outcomes is significant and future data collection is required to assess the effectiveness of the various treatments.

Abstract
CONTEXT Injury data on hip and groin injuries vary, and these injuries are often misrepresented or overlooked for more commonly seen injuries, such as those to the foot and ankle. OBJECTIVE To provide a systematic review of the injury rates of hip and groin pathology in dancers and look to establish a better understanding of the occurrence of hip and groin injuries in the dancer population. DATA SOURCES A literature search was performed using PubMed and CINAHL databases for articles published between 2000 and 2016. STUDY SELECTION Inclusion criteria consisted of (1) documentation of the number of hip and/or groin injuries, (2) study population consisting of dancers whose training included some level of ballet, and (3) studies of levels 1 through 3 evidence. STUDY DESIGN Systematic review. LEVEL OF EVIDENCE Level 3. DATA EXTRACTION A single reviewer identified studies that met the inclusion criteria. The number of overall injuries, hip/groin injuries, study participants, injured participants, training hours per week, mean age of study group, injury definition, injury reporting method, and study time frame were extracted. RESULTS Thirteen unique studies were included in the descriptive analysis. Of the 2001 dancers included in this study, 3527 musculoskeletal injuries were seen in 1553 dancers. Of these, 345 injuries were localized to the hip and groin region (overall rate, 17.2%). An incidence rate of 0.09 hip and groin injuries per 1000 dance-hours was seen in the selected cohort studies. Of 462 professional dancers, 128 hip/groin injuries were recorded, for an injury rate of 27.7%. Of the 1539 student dancers, 217 hip/groin injuries were recorded, for an injury rate of 14.1% ( P < 0.01). CONCLUSION Data on hip and groin injuries have many limitations. However, these injuries represent an important health issue for dancers of all skill levels, encompassing 17.2% of musculoskeletal injuries seen in dancers. An increasing rate of hip/groin injuries is seen in professional dancers compared with students.
