title: Responsiveness of clinical and laboratory measures to intervention effects in children with developmental coordination disorder.
abstract: OBJECTIVE
  To compare responsiveness of the Movement Assessment Battery for Children-2 (MABC-2) and segment kinematics and center of pressure measures in detecting intervention effects in children with developmental coordination disorder.
  
  
  METHODS
  Motion Analysis Laboratory (MAL) data from 21 children with developmental coordination disorder (mean age 11.0 years) in a randomized control trial were analyzed using effect size, minimal detectable difference, and parent and child report of meaningfulness (χ2 tests).
  
  
  RESULTS
  The MABC-2 and MAL data showed moderate-large effect sizes (0.7-1.8). The MABC-2 detected large portions of children whose change exceeded the minimal detectable difference (47.6%-71.4%); MAL data detected small portions (0%-19.0%). Neither tool correlated well with meaningfulness (χ2 = 0.186-5.724; P > .10). Both tools detected change in the overall group; however, only the MABC-2 detected individual change exceeding potential measurement error.
  
  
  CONCLUSIONS
  Although both assessment tools are responsive, they may be responsive to different types of change. Therefore, assessment constructs should be matched to intervention goals.
