BALLET DANCER INJURIES DURING PERFORMANCE AND REHEARSAL ON VARIED DANCE SURFACES

Abstract

Three dance surfaces regularly used by a professional touring ballet company (n=60) were quantified using standard sports surface testing apparatus. Surface sub-structure construction varied between surfaces and a range of surface force reduction values were reported. Injuries and associated variables occurring within the ballet company were recorded by the company medical staff. An injury was recorded if a dancer experienced an incident that restricted the dancer from performing all activities that were required of them for the period 24hrs after the incident. Injuries were delimited to those occurring in the lower limbs or trunk during reported non-lifting dance activity. Analysis of statistical significance was restricted due to a low injury data sample size. However certain trends in the injury data warrant future research. The surface with the highest variability in intra-surface force reduction was associated with the highest injury rates per week, lower limb injuries per week, mean days lost dancing per injury and likelihood of injury per performance day. Variability in intra-surface force reduction may have a stronger association with injury risk than mean surface force reduction magnitudes.
