Studying the Balance of the Coper and Non-Coper ACL-Deficient Knee Subjects.

Abstract

This study confirmed a balance deficiency in the injured and apparently healthy leg of the non-coper and coper ACL-D knee subjects. Increased COP path line length, sway velocity and the coinfidence ellipse area clearly showed an impaired body balance. The reduced postural control of the non-coper ACL-D knee subjects in bilateral standing could be more evidence of their poor knee stability status.
