      error scoring system.

AB  - CONTEXT: A clinical assessment tool that would allow for efficient large-group 
      screening is needed to identify individuals potentially at risk for anterior 
      cruciate ligament (ACL) injury. OBJECTIVE: To assess the criterion validity of a 
      jump-landing assessment tool compared with 3-dimensional (3D) motion analysis and 
      evaluate interrater reliability across an expert vs novice rater using the 
      Landing Error Scoring System (LESS). DESIGN: Validity protocol. SETTING: 
      Controlled, laboratory. PARTICIPANTS: Nineteen female (age 19.58 +/- .84 y, 
      height 1.67 +/- .05 m, mass 63.66 +/- 10.11 kg) college soccer athletes 
      volunteered. MAIN OUTCOME MEASUREMENT: Interrater reliability between expert 
      rater (5 y LESS experience) vs novice rater (no LESS experience). LESS scores 
      across 13 items and total score. 3D lower extremity kinematics were reduced to 
      dichotomous values to match LESS items. INTERVENTIONS: Participants performed 
      drop-box landings from a 30-cm height with standard video-camera and 3D kinematic 
      assessment. RESULTS: Intrarater item reliability, assessed by kappa correlation, 
      between novice and experienced LESS raters ranged from moderate to excellent 
      (kappa = .459-.875). Overall LESS score, assessed by intraclass correlation 
      coefficient, was excellent (ICC(2,1) = .835, P < .001). Statistically significant 
      phi correlation (P < .05) was found between rater and 3D scores for knee-valgus 
      range of motion; however, percent agreement between expert rater and 3D scores 
      revealed excellent agreement (range of 84-100%) for ankle flexion at initial 
      contact, knee-flexion range of motion, trunk flexion at maximum knee flexion, and 
      foot position at initial contact for both external and internal rotation of 
      tibia. Moderate agreement was found between rater and 3D scores for trunk flexion 
      at initial contact, stance width less than shoulder width, knee valgus at initial 
      contact, and knee-valgus range of motion. CONCLUSIONS: Our findings support 
      moderate to excellent validity and excellent expert vs novice interrater 
      reliability of the LESS to accurately assess 3D kinematic motion patterns. Future 
      research should evaluate the efficacy of the LESS to assess individuals at risk 
      for ACL injury.
