AB  - The aim of this study was to investigate the amount of attention demands of 
      postural control in patients with anterior cruciate ligament-reconstruction 
      (ACL-R), by comparing the pattern of posture-cognition interaction between two 
      groups of ACL-R patients (n=25) and healthy matched controls (n=25). All 
      participants were examined during single-leg stance on a balance board under both 
      single- and dual-task conditions in 4 dynamic balance tests. These tests were 
      standing on the injured and uninjured legs with straight or flexed knees. The 
      corresponding dominant and non-dominant legs of healthy group were considered as 
      controls. Contact frequency and contact time were acquired as a measure of 
      postural performance. Cognitive performance was assessed by counting the number 
      of errors in a silent backward digit span task. The results of analysis of 
      variance showed a significant higher contact frequency and longer contact time in 
      patients with ACL-R compared to healthy matched controls (p<0.02). Moreover, the 
      ACL-R patients showed a significantly higher contact frequency and longer contact 
      time during dual-task compared to single-task conditions (p<0.01). This pattern 
      of posture-cognition interference was not observed in the healthy control group. 
      In conclusion, patients who had undergone ACL-R surgery demonstrated poorer 
      balance stability during single-leg stance than healthy controls. Also, 
      simultaneous execution of the cognitive task during standing caused a significant 
      deterioration in postural stability which indicates decreased automaticity 
      (increased attention demanding) of postural control in patients with ACL-R 
      compared to healthy controls.
