TI  - Cognitive-Motor Dual-Task Performance of the Landing Error Scoring System.
PG  - 21-28

AB  - CONTEXT: The Landing Error Scoring System (LESS) is a common assessment used to 
      determine biomechanical landing errors. However, this assessment is completed as 
      a single motor task, which does not require additional attentional resources. It 
      is unclear if the LESS can be used to detect cognitive-motor interference (ie, 
      dual-task cost) in biomechanical errors associated with lower extremity injury. 
      OBJECTIVE: To determine if the LESS is a suitable clinical assessment of 
      dual-task performance in uninjured women and to evaluate whether specific landing 
      criteria are more affected by an additional cognitive load than others. DESIGN: 
      Cross-sectional study. SETTING: University research laboratory. PATIENTS OR OTHER 
      PARTICIPANTS: A total of 20 uninjured, physically active female participants (age 
      = 22.4 +/- 2.5 years, height = 1.68 +/- 0.07 m, mass = 67.0 +/- 13.8 kg, Tegner 
      Activity Scale = 5.9 +/- 1.1). INTERVENTION(S): Participants performed the LESS 
      under 3 different conditions: baseline landing with no cognitive distraction 
      (Single), a visual-based dual task (Visual), and a number-based dual task 
      (Number). MAIN OUTCOME MEASURES(S): Mean sagittal-plane, frontal-plane, and total 
      LESS scores were compared between conditions using a 1-way repeated-measures 
      analysis of variance with Tukey post hoc correction. A Cohen d effect size with a 
      95% confidence interval was used to determine the magnitude of differences. The 
      frequency of errors for each LESS item under the 3 conditions was compared using 
      chi2 analysis. RESULTS: Participants exhibited greater sagittal-plane (P = .02, d = 
      0.91; 95% confidence interval, 0.26-1.56) and total (P = .008, d = 1.03; 95% 
      confidence interval, 0.37-1.69) errors during the Visual condition than during 
      the Single condition. The frequency of errors observed for each LESS item did not 
      differ between conditions (all P > .05). CONCLUSIONS: The LESS was able to detect 
      a dual-task cost in landing errors during both the Visual conditions. We 
      recommend developing clinically oriented solutions to incorporate similar 
      dual-task paradigms in traditional injury risk-reduction programs.
