The physical assessments used in dance injury surveillance programs are often adapted from the sports and exercise domain. Bespoke physical assessments may be required for dance, particularly when ballet movements involve "turning out" or external rotation of the legs beyond that typically used in sports. This study evaluated the ability of the traditional single-leg squat to predict the leg alignment of dancers performing ballet movements with turnout. Three-dimensional kinematic data of dancers performing the single-leg squat and five ballet movements were recorded and analyzed...

Youichi Yasui, Charles P Hannon, Eoghan Hurley, John G Kennedy
Posterior ankle impingement syndrome (PAIS) is a common injury in athletes engaging in repetitive plantarflexion, particularly ballet dancers and soccer players. Despite the increase in popularity of the posterior two-portal hindfoot approach, concerns with the technique remain, including; the technical difficulty, relatively steep learning curve, and difficulty performing simultaneous anterior ankle arthroscopy. The purpose of the current literature review is to provide comprehensive knowledge about PAIS, and to describe a systematic four-stage approach of the posterior two-portal arthroscopy...

BACKGROUND: Although early accelerated rehabilitation is recommended for the treatment of acute Achilles tendon rupture, most traditional rehabilitation techniques require some type of brace. METHODS: We retrospectively analyzed 44 feet of 44 patients (25 male and 19 female) with a mean age of 31.8 years who had an acute Achilles tendon rupture related to athletic activity. Patients had been treated by a double side-locking loop suture (SLLS) technique using double antislip knots between stumps and had undergone early accelerated rehabilitation, including active and passive range of motion exercises on the day following the operation and full weight-bearing at 4 weeks...

There are no approved treatments for liver fibrosis. To aid development of antifibrotic therapies, noninvasive biomarkers that can identify patients with progressive fibrosis and that permit monitoring of the response to antifibrotic therapy are much needed. Samples from a phase II antifibrotic trial of the glitazone farglitazar in patients with advanced hepatitis C, with matched follow-up liver biopsies, and from a phase III study of balaglitazone in patients with late-stage Type 2 diabetes (BALLET study) were analyzed for serological Pro-C3 levels in conjunction with other disease parameters...

Constraining the conformation of flexible peptides is a proven strategy to increase potency, selectivity and metabolic stability. The focus has mostly been on constraining the backbone dihedral angles; however, the correct orientation of the amino acid side chains (Χ-space) which constitute the peptide pharmacophore is equally important. Control of Χ-space utilizes conformationally constrained amino acids which favor, disfavor or exclude the gauche (‒), the gauche (+) or the trans conformation. In this review we focus on cyclic aromatic amino acids in which the side chain is connected to the peptide backbone to provide control of Χ1- and Χ2-space...

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...

AIMS/HYPOTHESIS: The treatment of type 2 diabetes with full peroxisome proliferator-activated receptor gamma (PPARγ) agonists improves insulin sensitivity, but is associated with weight gain, heart failure, peripheral oedema and bone loss. Endotrophin, the C-terminal fragment of the α3 chain of procollagen type VI (also called Pro-C6), is involved in both adipose tissue matrix remodelling and metabolic control. We established a serum assay for endotrophin to assess if this novel adipokine could identify type 2 diabetic patients who respond optimally to PPARγ agonists, improving the risk-to-benefit ratio...

Fatigue in ballet dancers may lead to injury, particularly in the lower extremities. However, few studies have investigated the effects of fatigue on ballet dancers' performance and movement patterns. Thus, the current study examines the effect of fatigue on the balance, movement pattern, and muscle activities of the lower extremities in ballet dancers. Twenty healthy, female ballet dancers performed releve on demi-pointe before and after fatigue. The trajectory of the whole body movement and the muscle activities of the major lower extremity muscles were recorded continuously during task performance...

The aim of this work was to document molecular epidemiology of Rasamsonia argillacea species complex isolates from cystic fibrosis (CF) patients. In this work, 116 isolates belonging to this species complex and collected from 26 CF patients and one patient with chronic granulomatous disease were characterized using PCR amplification assays of repetitive DNA sequences, and electrophoretic separation of amplicons (rep-PCR). Data revealed a clustering consistent with molecular species identification. A single species was recovered from most patients...

BACKGROUND: Patients who trust their physicians are more likely to communicate about medical problems, adhere to medical advice, and be satisfied with care. Dancers have demonstrated low utilization of physician services for both preventive care and dance injuries. The purpose of this cross-sectional study was to examine trust in physicians as a variable influencing dancers' health care-seeking behavior. METHODS: The validated Trust in Physician Scale was administered to 45 professional and 34 student ballet/contemporary dancers in France (36...

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...

An athlete's cardiorespiratory profile, maximal aerobic capacity, and anaerobic threshold is affected by training regimen and competition demands. The present study aimed to ascertain whether there are company rank differences in maximal aerobic capacity and anaerobic threshold in elite classical ballet dancers. Seventy-four volunteers (M 34, F 40) were recruited from two full-time professional classical ballet companies. All participants completed a continuous incremental treadmill protocol with a 1-km/hr speed increase at the end of each 1-min stage until termination criteria had been achieved (e...

Ballet exposes the hip joint to repetitive loading in extreme ranges of movement and may predispose a dancer to pain and osteoarthritis (OA). The aims of this study were to compare the prevalence of cartilage defects in professional ballet dancers and athletes and to determine the relationship of clinical signs and symptoms. Forty-nine male and female, current and retired professional ballet dancers and 49 age- and sex-matched non-dancing athletes completed hip pain questionnaires, including the Copenhagen Hip and Groin Outcome Score (HAGOS), and underwent hip range of movement (ROM) testing and 3-Tesla magnetic resonance imaging to score cartilage defects (no defect, grade 1: focal partial defect and grade 2: diffuse or full thickness defect)...
