Abstract

Sway analysis in the sagittal plane was evaluated in 10 patients with chronic anterior cruciate ligament (ACL) deficiency of injured leg and the result was compared from uninjured leg of subjects. Measurement of tile body sway was done on a fixed and sway-referenced plate in both single-limb with the eyes open. Further, an analysis of the postural reactions to perturbations backwards and forwards, respectively, was made in single-limb stance. There was a significantly higher body sway within the patient group when standing on a stable support surface on the injured limb than standing on the uninjured limb with the eyes open, When standing on a stable support surface, there was a significantly higher body sway in the athlete group standing on the injured leg than in the control group, both with eyes open. When standing on the sway-referenced support surface, the patient group had a significantly larger body sway in injured leg than the uninjured leg when the eyes were open, We conclude that patients with a continuing chronic ACL insufficiency several years after injury have an impaired postural control in the antero-posterior direction in single-limb stance on their injured leg. They also show a greater body sway and a prolonged reaction time when subjected to anteroposterior perturbations when standing on their injured leg.
