TI  - Cognitive-Motor Dual-Task Performance of the Landing Error Scoring System.
LID - 10.4085/1062-6050-0558.23 [doi]
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 (i.e., 
      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 females and to evaluate whether specific 
      landing criteria are more affected by an additional cognitive load than others. 
      DESIGN: Observational Cross-Sectional Design. Setting: University research 
      laboratory. PATIENTS OR OTHER PARTICIPANTS: Twenty uninjured, physically active 
      females participated. Intervention(s): Participants performed the LESS under 
      three 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, frontal, and total LESS scores 
      were compared between conditions using a one-way repeated measures analysis of 
      variance with Tukey post hoc corrections. Cohen's d effect sizes with 95% 
      confidence intervals were used to determine the magnitude of differences. The 
      frequency of errors for each individual LESS item under the three conditions were 
      compared using Chi-Squared analyses. RESULTS: Participants exhibited greater 
      sagittal plane (P=.013, d=0.91 [0.26, 1.56]) and total (P=.008, d=1.03 [0.37, 
      1.69]) errors during the Visual condition compared to the Single condition. 
      Frontal plane errors were significantly greater during the Number condition 
      compared to the Single condition (P=.008, d=1.03 [0.37, 1.69]). The frequency of 
      errors observed for each LESS item did not statistically differ between 
      conditions (all P>.05). CONCLUSIONS: The LESS was able to detect a dual-task cost 
      in landing errors during both the Visual and Number conditions. We recommend 
      developing clinically-oriented solutions to incorporate similar dual- task 
      paradigms in traditional injury risk reduction programs.
