The differences in ground reaction forces components between sound and affected limb in patient with ACL rupture during vertical jump

Abstract:
Objectives
The aim of this study was to assess the differences in ground reaction forces components between sound and affected limb patient with ACL rupture during vertical jump.
Methods
Six men with ACLD (anterior cruciate ligament disease) were participated in this study. Ground reaction forces components was assessed during Sargent jump by kistler force plate. Data were analyzed by dependent T-test and Repeated Measure in set point of 0.05.
Result
Peak anterior posterior ground reaction forces was significantly greater in sound limb compared to affected limb during landing phase (P=0.04). During landing, vertical (p=0.00) and anterior posterior (p=0.01) impulse in sound limb was significantly greater than that of affected limb. There was no significant differences between loading and unloading rate between both side in take-off and landing phase (p
Conclusion
The pattern of vertical jump ground reaction forces change in landing phase after ACL rupture. Also, there is no difference in impact between injured and uninjured leg in take-off phase, but there is a big differences between two sides in landing phase. It is propose that people with ACL rupture avoid repeated jumping performance because the increased impact on sound leg can endanger the sound leg in risk of injury. Thereafter the possibility of ACL rupture of sound leg will be decreased.
