Reliability of Hip Strength Assessment in Young Active People with Hip Dysplasia: An Examination in Student Circus Artists
C. Ganderton, M.J.M. O’Brien, J. Han, A.K. Wallis, D. Munro, T. O’Shea, R. Grabinski, M.G. King

Developmental dysplasia of the hip (DDH) is common in performing artists and other young active individuals and involves abnormalities in bony morphology of the acetabulum and proximal femur that can negatively impact walking biomechanics, muscular strength, quality of life, and sleep. Rehabilitation for hip-related conditions should target known modifiable impairments such as hip muscle strength, though a reliable method of assessment in this population remains unclear. OBJECTIVE: To determine the inter- and intra-rater reliability of hip muscle strength assessments using handheld dynamometry (HHD) in young active circus artists with DDH.

Muscle Strength Asymmetries of the Lower Limbs and Trunk in Ballet Dancers
Nina Ogrinc, Monika Pavlović, Nejc Šarabon

Ballet dancers are expected to use their bodies symmetrically during training, because dance movements are performed on both sides. However, there is a general belief that ballet training encourages the use of one side of the body more than the other. Frequent repetition of a particular exercise can lead to body asymmetries and musculoskeletal injuries. The aim of this cross-sectional study was to investigate the presence of lower limbs and trunk muscle strength asymmetries in ballet dancers and secondly to assess whether there is a difference between professional dancers and ballet students.

Popular Musician Occupational Stress and Psychological Ill Health: An Exploratory Factor Analysis
Ben King, Jessica Koenig, Lloyd Berg

Popular musicians are exposed to many occupational stressors, including unpredictable work schedules, touring and economic precarity, that have been associated in prior studies with psychological ill health. This study sought to identify occupational stressors most strongly associated with depression, anxiety, and alcohol misuse in popular musicians.

Comparison of Perfectionism Between Music and Medical Students and its Association with Anxiety
Stine Alpheis, Eckart Altenmüller

Perfection is a central goal for many musicians and health professionals. The present study compared perfectionism between music and medical students to examine whether perfectionism is adaptive or maladaptive and how it evolves during university studies. Furthermore, the association between perfectionism and anxiety was investigated in both populations to determine possible implications for mental and general health.

Perspectives of Ballet Dancers on Causes of Their Injuries and Implementation of Injury Preventive Measures by Ballet Teachers and Masters
Judith-Elisa Kaufmann, Janine H. Stubbe, Rob G.H.H. Nelissen, Maaike G.J. Gademan

Ballet dancers have a high injury risk. We aimed to gain insight into the causes for acute and overuse injuries in ballet dancers and the level of implementation of injury prevention by ballet teachers/masters, as perceived by dancers. METHODS: An international cross-sectional online-survey was based on the Fit-to-Dance Questionnaire and literature. Adult amateur, pre-professional, and professional ballet dancers reported the perceived causes of their injuries sustained in the previous 2 years.

Incidence, Prevalence, and Characteristics of Injuries in Pole Dancers: A Systematic Review
Caitlin Scott, Quentin Scott, Simone Muscat

Pole dancing is an extreme form of per­formance physical activity, combining considerable feats of muscular strength, flexibility, dancing and acrobatics on a vertical metal apparatus. Despite rapid growth in the artform, many pole dancers continue to participate without fulfilling physical requirements to withstand the forces and physicality required. The aim of this systematic review was to determine the incidence, prevalence and characteristics of injuries sustained by pole dancing participants reported in published studies.
