Background:
Time to Boundary (TtB) quantifies the time available to redirect the center of pressure away from the base of support boundary during quiet standing.
Objective:
Given that test-retest data exist for this postural control measure in adult samples, the purpose of this study was to explore reliability of TtB in adolescents to quantify balance performance in the Modified Clinical Test of Sensory Interaction in Balance (CTSIB-M).
Methods:
Participants performed two 30 s quiet standing trials with eyes open or closed and with or without a foam pad. Average, minimum, and standard deviation of TtB were obtained for each trial.
Results:
Intraclass correlations (ICC) were greatest in the average or minimum TtB measures and least in the TtB standard deviation with trivial or small differences between trials (all contrast p > .05). These results suggest a single balance trial is appropriate for characterizing adolescents' postural control. Mean or minimum TtB scores demonstrate generally moderate to good reliability across conditions, while the standard deviation appears less consistent. Removing vision or introducing a compliant surface tended to reduce TtB magnitudes, emphasizing the challenges imposed by those conditions.
Conclusions:
We conclude TtB is a reliable method to quantify balance across a varied set of experimental conditions in the developing individual.
