The purpose of this study was to describe the effects of lower limb positioning
and shoe conditions on stability levels of selected single leg ballet poses
performed in demi-pointe position. Fourteen female non-professional ballet
dancers (mean age of 18.4+/-2.8 years and mean body mass index of
21.5+/-2.8kg/m(2)) who had practiced ballet for at least seven years, without any
musculoskeletal impairment volunteered to participate in this study. A capacitive
pressure platform allowed for the assessment of center of pressure variables
related to the execution of three single leg ballet poses in demi pointe
position: attitude devant, attitude derriere, and attitude a la second. Peak
pressures, contact areas, COP oscillation areas, anterior-posterior and
medio-lateral COP oscillations and velocities were compared between two shoe
conditions (barefoot versus slippers) and among the different poses. Barefoot
performances produced more stable poses with significantly higher plantar contact
areas, smaller COP oscillation areas and smaller anterior-posterior COP
oscillations. COP oscillation areas, anterior-posterior COP oscillations and
medio-lateral COP velocities indicated that attitude a la second is the least
challenging and attitude derriere the most challenging pose.
