Abstract

Many studies have already been conducted investigating proprioceptive deficits in subjects with rupture of the Anterior Cruciate Ligament (ACL). However, there are few data related using the paradigm of Force Matching Test. Objective of this study was to verify whether there is knee proprioceptive deficit when analyzed ACL-deficient knee with uninjured knee. 22 participants with ACL rupture and 22 participants with healthy knee were. ANOVA showed differences between the dependent variables Absolute Error and Variable Error, no difference was observed for the Peak Torque. This study concludes that the proprioception and neuromuscular control of force are affected by ACL injury. It may have important implications on the rehabilitation process following the ligament injury.
