title: [Simple and useful evaluation of motor difficulty in childhood (9-12 years old children ) by interview score on motor skills and soft neurological signs--aim for the diagnosis of developmental coordination disorder].
abstract: Many children with developmental disorders are known to have motor impairment such as clumsiness and poor physical ability;however, the objective evaluation of such difficulties is not easy in routine clinical practice. In this study, we aimed to establish a simple method for evaluating motor difficulty of childhood. This method employs a scored interview and examination for detecting soft neurological signs (SNSs). After a preliminary survey with 22 normal children, we set the items and the cutoffs for the interview and SNSs. The interview consisted of questions pertaining to 12 items related to a child's motor skills in his/her past and current life, such as skipping, jumping a rope, ball sports, origami, and using chopsticks. The SNS evaluation included 5 tests, namely, standing on one leg with eyes closed, diadochokinesia, associated movements during diadochokinesia, finger opposition test, and laterally fixed gaze. We applied this method to 43 children, including 25 cases of developmental disorders. Children showing significantly high scores in both the interview and SNS were assigned to the "with motor difficulty" group, while those with low scores in both the tests were assigned to the "without motor difficulty" group. The remaining children were assigned to the "with suspicious motor difficulty" group. More than 90% of the children in the "with motor difficulty" group had high impairment scores in Movement Assessment Battery for Children (M-ABC), a standardized motor test, whereas 82% of the children in the "without motor difficulty" group revealed no motor impairment. Thus, we conclude that our simple method and criteria would be useful for the evaluation of motor difficulty of childhood. Further, we have discussed the diagnostic process for developmental coordination disorder using our evaluation method.
