Developing the Positional Characteristics of a Dance-Specific Star Excursion Balance Test (dsSEBT).

Current dynamic balance tests do not sufficiently test all aspects of balance required for dancers in everyday training and performances. The aim of this study was to examine alterations to the Star Excursion Balance Test (SEBT) to ensure a more dance-specific protocol. Twenty-four healthy ballet and contemporary dancers (age: 22.21 ± 6.47 years) participated in completing five different variations of the SEBT. This research implemented upper-body restrictions commonly used in dance settings and tested the effects of two different foot positions, parallel and turned out, as well as two alternate balance surfaces, a foam balance pad and a firm yoga block. Reach distances (percent of limb length), center of pressure (COP, cm²), error scores, and time to completion were measured. Overall, the dance-specific upper body restrictions did not affect the dancer's ability to reach maximally and achieve a successful trial as there were no significant differences between the original SEBT and the dance-specific SEBT parallel condition (p = 1.00). The foam and block conditions were found to be significantly more difficult due to lower reach distance values, higher COP values, and higher error score values when compared to the original, parallel, and turnout positions (p < 0.05). Lastly, it was discovered that 62.61% of all errors made were in the crossed side and crossed front spokes, suggesting these are the most difficult reach directions to accomplish. The variations used in the study will aid in developing a reliable dance-specific dynamic balance test.
