Classical ballet is a performance art where unintentional and uncontrolled movement degrades the aesthetic. Vertical torso movement can induce body tilt. Postural sway was measured in pre-professional ballet dancers when performing simple vertical movements. 47 pre-professional dancers (5 males and 42 females, mean age in years = 19.2, SD= ± 1.3) on a full time undergraduate dance program were asked to stand in first position and perform a demi-plié, a relevé and a sauté. These movements were performed in a continuous cycle undertaken 15 consecutive times. The first 5 cycles were undertaken as practice. The second set of 5 cycles were recorded with the arms held in Bras bas, with the final 5 having the arms held in fifth position (rounded arms placed above the head). Accelerometers were attached to the lumber spine (L4) and thoracic spine (T1-T2). The tilt during the demi-plié prior to the sauté and relevé increased significantly for both arm positions. The male participants preparative angle change was much larger than the female participants (p = 0.07). No significant angle change was observed between the Bras bas and arms in fifth position for the sauté but the change is significant for the relevé (p = 0.007). Exaggerated forward tilt is undesirable both aesthetically and biomechanically. Small accelerometer sensors on the spine can allow self-monitoring practice of these basic classical ballet movements.

Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
