An investigation of postural control in postoperative anterior cruciate ligament reconstruction patients.

Abstract

Evaluation of the postural control system under 2 conditions, static and dynamic, showed differences between the ACL and control groups for the dynamic condition only. These results suggest the presence of independent control mechanisms for the control of static and more dynamic postures. In addition, because there were no differences between the injured and noninjured legs of the ACL group, the theory of a central postural control scheme is supported.
