Assessment of the Symmetry of the Ground Reaction Forces in Patient with ACL Rupture during Vertical Jump

Objectives: The aim of this study was to assess the symmetry of ground reaction forces in patient with ACL rupture during vertical jump. Methods: Six men with ACLD (anterior cruciate ligament disease) participated in this study. Ground reaction forces components were assessed during Sargent jump by Kistler force plate. Data were analyzed running dependent Samples T-test and Repeated Measure in at p≤0.05. Result: Peak anterior posterior ground reaction forces were significantly greater in sound limb compared to the affected limb during landing phase (P=0.04). During landing, vertical (p=0.00) and anterior posterior (p=0.01) impulse in sound limb were significantly greater than those of affected limb. There were no significant differences between loading and unloading rates between both side in take-off and landing phases (p
