title: Reference values and psychometric properties of the lower extremity motor coordination test.
abstract: OBJECTIVE
  (1) To create predictive nomograms for the dominant and nondominant limbs on the Lower Extremity Motor Coordination Test (LEMOCOT) using reference values, and (2) to determine the inter- and intrarater reliability for the LEMOCOT; the best scoring method (first vs mean of the first 2 vs mean of the last 2 vs mean of 3 vs the highest of 3 trials); the best testing method (direct vs video observation); and the ability to detect real change (smallest real difference [SRD] and standard error of the measurement [SEM]).
  
  
  METHODS
  Normative and methodological study.
  
  
  METHODS
  Metropolitan area.
  
  
  METHODS
  Healthy individuals (N=320, 50% women) in 7 age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, and ≥80 years. Each group had 50 participants, except for ≥80 years (n=20).
  
  
  METHODS
  Not applicable.
  Age and sex explained 48% of the variance in the LEMOCOT scores for the dominant limb and 44% for the nondominant limb (125<F<148; P<.001). No significant differences were found regarding the different scoring methods (.12<F<1.02; .10<P<.92), and all of them demonstrated good reliability (intraclass correlation coefficients between .90 and .99; P<.001). There was agreement between scores from direct and video observation (limits of agreement -1.99 to 1.85; -1.55 to 1.62). Appropriate SEM (2.27-1.85) and SRD (6.27-5.11) values were found.
  
  
  CONCLUSIONS
  Reference values were determined for the LEMOCOT, and predictive nomograms were created based on age and sex. The LEMOCOT is reliable, needing only 1 trial (after familiarization) to generate reliable scores; can be scored from either direct or video observation; and has the ability to detect real change over time.
