Abstract

Objective: To examine test-retest reliability of the Stability Evaluation Test (SET) protocol of the VSR™-Sport in a pediatric sample using clinically relevant timeframes and to investigate gender and age group differences on test-retest reliability in this sample.
Design: Repeated Measures Design.
Setting: Community youth center.
Participants: Fifty–four healthy children, aged 4-15 years, completed all three testing sessions.
Interventions: Participants completed the SET three times over the course of 35 days: day 1, day 30 and day 35.
Main Outcome Measures: Sway velocity (deg/sec) for six conditions and a composite of the SET was measured on testing days. An interclass correlation coefficient (ICC) was calculated using SPSS 20.0.
Results: Each testing timeframe elicited clinically acceptable test-retest reliability for composite SET scores: timeframe 1ICC=.91(.84-.95, 95% CI), Timeframe 2ICC=.92(.86- .95, 95% CI) and Timeframe 3ICC=.86(.76-.92, 95% CI). Some variation existed in testretest reliability when comparing males to females and a younger cohort to an older cohort, all ICC’s demonstrated clinically acceptable findings.
Conclusions: Strong test-retest reliability of SET is necessary to ensure that impairments defined post-concussion using this method are due to the condition, and not unreliable tests. Findings support strong test-retest reliability of the SET in a healthy pediatric sample when delivered over timeframes following current concussion management protocols, even with considerations for age and gender. The ability to measure sway velocity on the VSR-Sport rather than balance errors in the BESS allows for an objective measurement of balance over time.
