OBJECTIVE: To examine the reliability, convergent, and discriminant validity of
the limits of stability (LOS) test to assess dynamic postural stability in
adolescents using a portable forceplate system.
DESIGN: Cross-sectional
reliability observational study. SETTING: School setting. PARTICIPANTS: Adolescents
(N=36) completed all measures during the first session. To examine
the reliability of the LOS test, a subset of 15 participants repeated the LOS
test after 1 week. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Outcome
measurements included the LOS test, Balance Error Scoring System, Instrumented
Balance Error Scoring System, and Modified Clinical Test for Sensory Interaction
on Balance. RESULTS: A significant relation was observed among LOS composite
scores (r=.36-.87, P<.05). However, no relation was observed between LOS and
static balance outcome measurements. The reliability of the LOS composite scores
ranged from moderate to good (intraclass correlation coefficient model
2,1=.73-.96). CONCLUSIONS: The results suggest that the LOS composite scores
provide unique information about dynamic postural stability, and the LOS test
completed at 100% of the theoretical limit appeared to be a reliable test of
dynamic postural stability in adolescents. Clinicians should use dynamic balance
measurement as part of their balance assessment and should not use static balance
testing (eg, Balance Error Scoring System) to make inferences about dynamic
balance, especially when balance assessment is used to determine rehabilitation
outcomes, or when making return to play decisions after injury.
