The purpose of this study was to describe the effects of two stretching techniques on standing hip range of motion (ROM) in female dancers. The participants were 18 university students. They were randomly assigned to one of three groups: active stretch group (Bartenieff Fundamentals(TM) thigh lift), passive stretch group (contract-release-contract form of PNF), or a control group. The participants assigned to the stretching groups completed 12 sessions of their randomly assigned stretch technique over a 3-week period...

Ballet dancers are high-performance athletes who are particularly susceptible to a wide variety of musculoskeletal injuries. However, they are relatively understudied, and data on their injury rates are lacking. This retrospective study features the largest aggregate data on professional ballet dancers to date and aims to identify the most common diagnoses and areas of injury in this unique population to better direct preventative and clinical practices. The study encompassed a 10-year period from January 2000 to December 2010 of dancers from a single company...

Focus of attention and its effects on skilled motor performance has become an important line of research in the motor learning domain. Numerous studies have demonstrated that an external focus of attention (i.e., on the movement effect) enhances motor performance and learning relative to an internal focus (i.e., on body movements). Thus, small differences in the wording of instructions or feedback given by teachers can have a significant impact on the effectiveness and efficiency of motor skill performance...

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...

Low range femoral torsion, termed "lateral shaft torsion," has been associated with greater range of hip external rotation and turnout in dancers. It is also hypothesized that achieving greater turnout at the hip minimizes torsion at the knee, shank, ankle, and foot, and consequently reduces incidence of lower limb injuries. The primary aims of this study were to investigate: 1. differences in range of femoral shaft torsion between dancers with and without lower limb injuries; and 2. the relationship between femoral shaft torsion, hip external rotation range, and turnout...

In dance, the goals of actions are not always clearly defined. Investigations into the perceived quality of dance actions and their relation to biomechanical motion should give insight into the performance of dance actions and their goals. The purpose of this review was to explore and document current literature concerning dance perception and its relation to the biomechanics of motion. Seven studies were included in the review. The study results showed systematic differences between expert, non-expert, and novice dancers in biomechanical and perceptual measures, both of which also varied according to the actions expressed in dance...

A cross-sectional design was employed retrospectively to evaluate injuries self-reported by 71 pre-professional ballet dancers over one season. Some of the descriptive findings of this survey were consistent with those of previous research and suggest particular demographic and injury trends in pre-professional ballet. These results include gender distribution, mean age and age range of participants, training hours, injury location, acute versus overuse injuries, as well as average number of physiotherapy treatments per dancer...

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...

This study is to draw attention to a relatively common anatomical anomaly and its possible operative treatment in dancers. The accessory navicular, or os tibiale externum, is an accessory bone on the medial side of the navicular of the foot at the insertion of the posterior tibial tendon (PTT). It can cause obvious hyperpronation, medial foot pain, and a limited and painful relevé in dancers. To the best of our knowledge, this is the first report on the operative treatment of the accessory navicular exclusively in dancers...

This study examines the current utilization of primary and preventive health care services among dancers in order to assess their self-reported primary care needs. Participants were 37 dancers from a variety of dance backgrounds who presented for a free dancer health screening in a large US metropolitan area (30 females, 7 males; mean age: 27.5 ± 7.4 years; age range: 19 to 49 years; mean years of professional dancing: 6.4 ± 5.4 years). Dancers were screened for use of primary care, mental health, and women's health resources using the Health Screen for Professional Dancers developed by the Task Force on Dancer Health...

Despite recent improvements in their concussion knowledge, athletes still demonstrate risky concussion behaviors (e.g., playing while concussed or not reporting a concussion). Little has been published about dancers' concussion knowledge and behaviors, but research in dance contending with questions about injury in general has found that dancers often avoid physician consults and ignore the signs of injury. In the present study, an IRB approved anonymous online survey, it was hypothesized that dancers would demonstrate concussion knowledge deficits, fail to report concussions, and have difficulty adhering to management guidelines...

Thai classical dance is a traditional dramatic art, the technique of which has many features in common with South East Asian performing art. The choreographic patterns consist of various forms of balance control together with limb movements in slow rhythm. The grace and beauty of the dancer are dependent on how well the limb movements curve and angle. The relationship of whole body proportion and balance control in various patterns of support base is also important. The purpose of this study was to compare balance abilities between Thai classical dancers and non-dancers in different balance conditions...

Resistance training often is not an inherent component of current dance training for pediatric female dancers. Reasons for this include concerns surrounding injury to the immature skeleton and diminishing dancer aesthetic appearance, as well as questions related to the effectiveness of such training for increasing dancer strength and muscle endurance. Many forms of dance demand sufficient muscle strength and endurance for prolonged periods of high intensity dance, power generation during leaps and jumps, as well as stabilization of the lower extremity to prevent injury...

Dance imagery is a consciously created mental representation of an experience, either real or imaginary, that may affect the dancer and her or his movement. In this study, imagery research in dance was reviewed in order to: 1. describe the themes and ideas that the current literature has attempted to illuminate and 2. discover the extent to which this literature fits the Revised Applied Model of Deliberate Imagery Use. A systematic search was performed, and 43 articles from 24 journals were found to fit the inclusion criteria...

Rope and harness vertical dance takes place off the floor with the dancer suspended from his or her center of mass in a harness attached to a rope from a point overhead. Vertical dance represents a novel environment for training and performing in which expected stresses on the dancer's body are different from those that take place during dance on the floor. Two male and eleven female dancers with training in vertical dance performed six typical vertical dance movements with electromyography (EMG) electrodes placed bilaterally on rectus abdominus, external oblique, erector spinae, and latissimus dorsi...

The Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2) adapted for dance has been employed in a variety of dance settings. However, the content validity of the measure and the relevance of particular subscales (e.g., Intra-Team Member Rivalry) have been questioned. Thus, the aims of this study were twofold: first, to examine the content validity of the PMCSQ-2 and identify problematic items and the nature and frequency of such problems experienced by dancers completing the measure; and second, to determine whether the content of task-involving and ego-involving climates, as captured in the subscales of the PMCSQ-2, are relevant and meaningful in dance contexts...

The objective of this study was to provide an epidemiological review of the literature concerning ballet injuries affecting pre-professional ballet dancers. The literature search was limited to published peer-reviewed reports and involved an extensive examination of Scopus, SPORTDiscus, and CINAHL. The following search terms were used in various combinations: ballet, injury, epidemiology, risk factor, pre-professional, and intervention. Additional citations were located using the ancestry approach. Unlike some other athletic activities that have been the focus of recent intervention research, there is a paucity of intervention and translational research in pre-professional ballet, and sample sizes have often been small and have not accounted for the multivariate nature of ballet injury...

Chronic Lisfranc injury is a subtle and severe injury in high-level athletes, including dancers. This patient population is generally intolerant of intra-articular screw fixation and can develop significant post-traumatic arthritis with potentially career ending complications. Flexible fixation with suture-button devices provides potential restoration of physiologic motion at the joint, with appropriate support for healing that may facilitate return to en pointe activities for dancers. We hypothesized that the suture-button device would restore motion at the Lisfranc joint and allow for return to activities in this particular population without the limitations and complications of rigid fixation...

A 26-year-old female professional dancer sustained an acute injury to her mid-foot during a performance of The Nutcracker. An intra-articular, comminuted, minimally displaced fracture of the cuboid was found. The patient was treated non-operatively with cast and boot immobilization, modified weightbearing, and progressive rehabilitation. She was able to return to professional dance at 6 months post-injury and continues to dance professionally over 1 year out from injury without issue. The unique demands of classical ballet, especially dancing en pointe, increase the risk for mid-foot fractures, and clinicians should have a high-index of suspicion in dancers suffering an acute injury to the foot and ankle with greater than expected pain or swelling...

The aim of our study was to determine if the Sardinian folk dance ballu sardu (BS) can be identified as an effective workout regimen in terms of its exercise intensity (EI) and energy expenditure (EE) and if people who perform BS fulfill the recommendations of the American College of Sports Medicine on the prescription of exercise in healthy subjects. Twenty healthy volunteers (10 men, 10 women, 35.2 ± 6.3 years of age, BMI 23.0 ± 3.4 kg/m²) with BS experience (mean = 20.7 ± 8.9 years) were enrolled. All subjects underwent a maximal cardiopulmonary exercise test...
