Critical appraisal of research investigating risk factors for musculoskeletal injury in dancers suggests high quality reliability studies are lacking. The purpose of this study was to determine between-day reliability of pre-participation screening (PPS) components in pre-professional ballet and contemporary dancers. Thirty-eight dancers (35 female, 3 male; median age; 18 years; range: 11 to 30 years) participated. Screening components (Athletic Coping Skills Inventory-28, body mass index, percent total body fat, total bone mineral density, Foot Posture Index-6, hip and ankle range of motion, three lumbopelvic control tasks, unipedal dynamic balance, and the Y-Balance Test) were conducted one week apart...

Elevé is a fundamental dance movement practiced routinely by dance students and serving as an integral component of screening in dance. It consists of ankle plantar flexion (PF) movement and is considered to be a frequent cause of foot and ankle injuries among dancers, with adolescent female dance students being at greatest risk for such injuries. Therefore, gaining additional knowledge regarding elevé functional range of motion (ROM) and inter-leg weightbearing distribution (WBD) properties among adolescent dance students is warranted for pedagogic, screening, injury prevention, and rehabilitation purposes...

Posterior ankle impingement syndrome (PAIS) is a painful, usually limited plantar flexion of the ankle joint due to soft tissue impingement or a bony impediment often coinciding with tendinopathy of the flexor hallucis longus (FHL) behind the medial malleolus. In persistent complaints, the bony impediment is removed, the tunnel of the FHL tendon is released, or a combination of both procedures has traditionally been performed by open surgery. In 2000, an endoscopic surgical technique for PAIS and FHL tendinopathy was introduced...

Turnout is a central element of classical ballet which involves sustained external rotation of the lower limbs during dance movements. Lower leg and foot compensation mechanisms which are often used to increase turnout have been attributed to the high incidence of lower limb injury in dancers. Evaluation of dancers' leg posture is needed to provide insight into the lower limb kinematic strategies used to achieve turnout. The primary purpose of this study was to use 3D kinematic analyses to determine the lower leg and foot compensations that are incorporated by female university dancers to accentuate their turnout...

Dance is a popular activity associated with many physical and mental health benefits, but injuries are a concern for all skill levels. Previous studies have focused on professional dancers or particular genres, meaning the population-wide characteristics of injuries is unknown. This study's objective was to identify the incidence and types of dance-related injuries evaluated in emergency departments in the United States over the 14-year period 2000-2013. METHODS: Data were obtained from the nationally representative National Electronic Injury Surveillance System from 2000-2013...

BACKGROUND: Healthcare events related to diabetic foot disease carry a burden of morbidity, mortality and economic cost. Prompt identification of clinical infection with appropriate tissue sampling limits use of broad spectrum empirical antibiotics and improves antibiotic stewardship. Staphylococcus aureus remains the commonest infecting organism and high-dose flucloxacillin remains the empirical antibiotic of choice for antibiotic naïve patients. Barriers to microbe-specific treatment include: adequate tissue sampling, delays in culture results, drug allergies and the emergence of multidrug-resistant organisms which can complicate the choice of targeted antibiotics...

BACKGROUND: Turnout in ballet is produced through summation of the joint structure characteristics and ranges of motion at the hip, knee, ankle, and foot. Contributions of the hip joint to functional turnout in dancers have received extensive examination, whereas little is known about contributions from the knee, ankle, and foot. The aim of this study was to explore the nonhip components of turnout to dancers' functional turnout in first position by assessing passive external tibiofemoral rotation and active measures of foot pronation, ie, navicular drop and Foot Posture Index...

The purpose of this study was to evaluate the midfoot longitudinal arch height and correlate it with active hip external rotation (ER) in dancers during static postures and technical steps of classical ballet (i.e., first position, demi-plié, battement fondu à la seconde, pas jeté à la seconde, and grand jeté à la seconde). A 3D motion analysis system was used for kinematic analysis. The arch height was significantly reduced during the battement fondu à la seconde, pas jeté à la seconde, and grand jeté à la seconde when compared to standing (p = 0...

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...

The purpose of this study was to determine the intra and inter-assessor repeatability of a modified Rizzoli Foot Model for analysing the foot kinematics of ballet dancers. Six university-level ballet dancers performed the movements; parallel stance, turnout plié, turnout stance, turnout rise and flex-point-flex. The three-dimensional (3D) position of individual reflective markers and marker triads was used to model the movement of the dancers' tibia, entire foot, hindfoot, midfoot, forefoot and hallux. Intra and inter-assessor reliability demonstrated excellent (ICC ≥ 0...

Theatre performers, more than common actors, experience high physical loadings. This study aimed at analysing the motor behaviour ofnovice performers (dancers/actors who were introduced to the acting method of Jan Fabre), by investigating the kinematics of a physical acting exercises in a prospective study. Two measurement sessions were organised, before and after the novice performers (n = 13) took part in seven workshops. Total body kinematics were registered using a 3D motion capture system. By using a Principal Component Analysis (PCA), six factors were disseminated out of 30 kinematic parameters: Pelvic Motion, Speed of Progression, Lower Limb Position, Foot Motion, Lower Limb Motion and Trunk Position...

BACKGROUND: Postural balance (PB) is an important component skill for professional dancers. However, the effects of different types of postures and different underfoot surfaces on PB have not been adequately addressed. PURPOSE: The main aim of the present study was to investigate the effect of different conditions of footwear, surfaces, and standing positions on static and dynamic PB ability of young ballet dancers. METHOD: Thirty-six male and female young professional ballet dancers (aged 14-19) completed static and dynamic balance testing, measured by head and lumbar accelerometers, while standing on one leg in the turn-out position, under six different conditions: 1...

Very little is known about patellofemoral pain syndrome (PPFS) among young dancers. Understanding the mechanism of the injury and implementing a preventative programme are important in order to minimize the risk of PFPS. The aim of the current study is to determine the extent to which factors such as lower extremity and back characteristics are common among dancers with PFPS. The study population included 271 dancers with PFPS and 271 non-injured dancers, aged 10-16 years. All dancers were screened for morphometric profile, dance discipline (h/week), anatomical anomalies (present/absent of scoliosis, genu valgus/varum, etc...

The present study reports the clinical results of excision of a symptomatic os trigonum using an endoscopic procedure in professional ballet dancers. The hypothesis was that posterior endoscopic excision of the os trigonum would be safe and effective in treating posterior ankle impingement syndrome related to the os trigonum. Twelve professional dancers underwent excision of a symptomatic os trigonum for PAIS using a posterior endoscopic technique after failure of conservative treatment. The patients were evaluated pre- and postoperatively according to the American Orthopaedic Foot and Ankle Society hindfoot scale score, the Tegner activity scale score, and the visual analog scale score...

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...

BACKGROUND: Screening and training of professional dancers is commonly based around beliefs that a large range of turnout is more advantageous in the ballet industry. This belief leads dancers who have limited hip external rotation to compensate by forcing turnout at the knee and ankle, which has been linked to injury. OBJECTIVE: To examine if there is a difference in degree of turnout between three levels of dancers (corps, soloist, principal) in a professional classical ballet company...
