EFFECTS OF LEG DOMINANCE ON THE SINGLE LEG HOP FUNCTIONAL TEST IN NON-INJURED ADULTS

Abstract

The purpose of this study was to determine the effects of leg dominance on the single leg hop (SLH) functional test used in ACL rehabilitation. Twenty-two subjects performed four manipulative, and two standing balance tests to determine leg dominance; and three trials of a standing broad jump and the single leg hop test on both lower limbs. Ground reaction forces were measure using two force platforms (AMTI) and the distance jumped were recorded. T-tests for dependent measure (SPSS) were used to determine difference between dominant and non-dominant limb. Subjects were able to significantly jump farther, produce more vertical and horizontal ground reaction forces when using the dominant leg, except when they jumped from both legs. Clinicians should take in consideration the effects of leg dominance on the single leg hop test results.
