Computerized platform posturography for children: test-retest reliability of the sensory test of the VSR System.
The purpose of this study was to examine the consistency of scores from typically developing children on the sensory test of the NeuroCom International VSR System. Participants included 18 children between five and nine years of age. Postural sway was measured using the VSR System, a computerized platform posturography assessment tool. The sensory test protocol examines the relative contributions of the visual, somatosensory, and vestibular systems to maintain postural stability by systematically manipulating the availability and accuracy of sensory inputs. Test-retest intraclass correlation coefficients for all four sensory conditions ranged from .76 to .83.
