ABSTRACT: The Balance Error Scoring System (BESS) is a subjective clinical balance assessment frequently used by various healthcare providers. A test administrator records the number of pre-defined errors committed by the test subject as they perform a number of balance stances.

PURPOSE: The purpose of this study was to determine if there is a difference in the number of observed errors between the 1st and 2nd 10 second time intervals of the assessment.

METHODS: 44 subjects (19.6 + 1.2 yrs) performed a familiarization trial immediately followed by an experimental trial. All trials were scored by a Certified Athletic Trainer.

RESULTS: BESS errors during the 1st and 2nd 10 second time intervals were 2.8 ± 2.4 and 3.3 ± 2.8 respectively. Paired samples t-test reveals no significant difference between the means.

CONCLUSION: Our results conclude that there is no significant difference in observed errors between the 1st and 2nd 10 second time intervals of BESS.
