Overview

Comparative cross-sectional study shows ballet dancers have better postural sway and lower coefficient of variance compared to untrained individuals.

Key Points

  • The study aims to explore differences in postural sway and spinopelvic kinematics between ballet dancers and untrained individuals.
  • Comparative cross-sectional study design
  • Involves 11 ballet dancers and 10 untrained individuals
  • Measured COP path length, mean angular position, and coefficient of variance
  • Analyzed data using a two-way repeated-measures ANOVA and post-hoc tests
  • Assessed correlations between COP path length and various kinematics
  • Dancers exhibited shorter COP path length in demi-pointe compared to untrained individuals
  • Dancers showed greater ankle plantar flexion in elevated positions
  • Co-efficient of variance increased with heel height in both groups
  • Dancers correlated COP path length with hip and knee angles
  • Untrained individuals correlated COP path length with co-efficient of variance in spinal-pelvis and lower limb areas
