Injury in ballet: a review of relevant topics for the physical therapist

Currently, there is a need for a review of the literature on ballet injury as it pertains to the physical therapist. Relatively few articles have reviewed ballet injury prevalence and mechanisms of injury. The purpose of this paper was to provide a thorough literature review of the prevalence of ballet injury and mechanisms of injury. Environmental factors and footwear relating to ballet injury were also reviewed. The literature indicated that 65-80% of ballet injuries are in the lower extremity, 10-17% occur in the vertebral column, and most of the remaining percentage are upper limb injuries (5-15%). The etiology of common lower limb conditions included an incorrect turnout; soft tissue imbalances; reduced quadriceps performance; "rolling in of the foot;" inversion sprains; and frequent pliés, pointé, and demipointé work. Spinal conditions were reported to result from hyperextension and hyperlordosis of the lumbar spine as well as the psoas insufficiency syndrome. It was revealed that inappropriately fitting footwear lead to various foot conditions and abnormal lower kinetic chain biomechanics. Environmental factors, such as the dance surface, also have implications in ballet injury. The author concluded that ballet injuries have a multifactorial etiology that primarily involves the interplay of compensatory biomechanics in the spine and lower extremity, environmental factors, and footwear. In addition, some clinical recommendations have been made regarding the physical therapy management of ballet injuries.
