Abstract
INTRODUCTION: The relationship between tibial acceleration and dance is a limited field of study. Injuries, both from overuse and asymmetry, are prevalent in the dance world, especially towards a dancer’s dominant leg.
PURPOSE: The purpose of this study was to determine the presence of asymmetry among contemporary and ballet dancers in their typical classes.
METHODS: Two experienced female dancers (22/22 years of age, 177.8/160cm, 83.9/55kg, 13/19 years experience) participated in the study and wore tibia-mounted IMU devices bilaterally during five routine dance classes (one ballet, one contemporary). A custom Python script filtered tri-axial accelerations collected at 1600Hz, computed resultant acceleration and symmetry angles were computed for low, moderate, and high impact peaks.
RESULTS: Symmetry angles for both participants, as well as the means and standard deviations for each angle, were calculated. For the contemporary dancer, the averages were as follows (in percentages): low impact peaks = 1.86 ± 0.64, moderate impact peaks = 3.59 ± 0.64, high impact peaks 14.10 ± 5.35. For the ballet dancer, the averages were as follows (in percentages): low impact peaks = 4.26 ± 1.81, moderate impact peaks = 1.38 ± 1.63, high impact peaks = 6.41 ± 7.50.
DISCUSSION: For both the ballet and contemporary dancers, larger asymmetries occur at higher impact peaks as compared to low and moderate impact peaks. The asymmetries are not all in the same direction. The IMU devices were tolerated by dancers and allowed in-field monitoring of dance tibial loads; their use should be considered for future studies.
