Musculoskeletal injuries and pain in dancers: a systematic review update.
The objective of this study was to assemble and synthesize the best available literature from 2004 to 2008 on musculoskeletal injury and pain in dancers. MEDLINE and CINAHL were the primary sources of data. Indexed terms such as dance, dancer, dancing, athletic injuries, occupational  injuries, sprains and strains, musculoskeletal diseases, bone density, menstruation disturbances, and eating disorders were used to search the databases. Citations were screened for relevance using a priori criteria, and relevant studies were critically reviewed for scientific merit by the  best-evidence synthesis method. After screening, 19 articles were found to be scientifically admissible. Data from accepted studies were abstracted into evidence tables relating to: prevalence and associated factors; incidence and risk factors; intervention; and injury characteristics and  prognosis of musculoskeletal injury and pain in dancers. Principal findings included: a high prevalence and incidence of lower extremity, hip and back injuries; preliminary evidence that psychosocial and psychological issues such as stress and coping strategies affect injury frequency and  duration; history of a previous lateral ankle sprain is associated with an increased risk of ankle sprain in the contralateral ankle in dance students; fatigue may play a role in ACL injury in dancers; acute hamstring strains in dancers affect tendon more than muscle tissue, often resulting  in prolonged absence from dance. It is concluded that, while there are positive developments in the literature on the epidemiology, diagnosis, prognosis, treatment, and prevention of MSK injuries and pain in dancers, much room for improvement remains. Suggestions for future research are offered.
