Abstract
Background: Single Leg Stance (SLS) testing is used in clinical assessments of balance, but little is known about the temporal structure of sway parameters during this test. SLS research is equivocal on the effects of sway over time and the direction of balance initiation. Sway data in a healthy young population may provide insight on how balance is initiated and maintained in relation to the initial step direction. This may lead to novel approaches to help healthy elderly populations decrease fall risk and fall-related mortality. Purpose: The purpose of the study was to examine the temporal and directional dependencies of sway parameters during 10 seconds of SLS in young, healthy adults. Methods: Six healthy, young college students (five male, one female) performed 10 seconds of SLS on their dominant leg, stepping from a frontward and sideward direction. Ground reaction forces measured with a force platform were used to calculate the sway parameters: sway area, sway velocity, anterior-posterior and medio-lateral sway, and sway path. Preliminary Results: Compared to the final second, the sway area, path and velocities were significantly higher in seconds one and two in the forward and sideward directions. Anterior-posterior sway was lower during seconds one and two in the forward direction. Medio-lateral sway was higher in second 2 in the forward direction, and lower at seconds one, two, and four in the sideward direction.
