The Development and Reliability of an Updated Dance-Specific Star Excursion Balance Test Protocol

Background: While the previous research has made crucial developments in a dance-specific version of the SEBT, current modifications to the SEBT have not conclusively produced a valid dance-specific dynamic balance test. Purpose: The aim of this paper was to utilize the most practical dance-specific variations from previous research and incorporate them into a reliable test to be considered for future screenings for dancers. Methods: Twenty-one female dancers voluntarily took part in the research (age: 20.86 +/- 3.68 years). This protocol consists of 3 stages, each increasing in difficulty; stage one: dsSEBT Average Tempo, stage two: dsSEBT Block, and stage three: a combination of stage 1 and stage 2, the dsSEBT Average Tempo on Block. Reach distance (% of limb length), error scores, and average time to complete each stage were recorded. A stage completion criteria was developed to move from one stage to the next wherein certain reach distance and error score standards needed to be met. Results: Between previous research using the same participants and the current study, each reach direction exhibits a statistically significant correlation (P < .05) with good to excellent ICC values ranging from .750 to .918, suggesting that test-retest reliability is high. Overall, 90.48% of participants succeeded in passing stage one, 19.05% of total participants passed stage two, and only 4.76% of the 21 participants passed all 3 stages with statistically significant differences detected for reach distance and incomplete trials between stages (P < .05). Conclusion: This data suggests that the test is challenging enough to show dancers weaknesses and push the limits of their balance capabilities. With a clear increase in difficulty from stage to stage, the test adds layers of demanding tasks designed to test the dancer proprioceptively.
