title: Reaction time and movement time in children with a Developmental Coordination Disorder.
abstract: The Test of Motor Impairment (TOMI) was used to select 12 children with a Developmental Coordination Disorder (DCD) and 12 age-matched controls. In an aiming task, movement latency, movement duration and its variability were significantly prolonged in the DCD group. In a coincidence timing version of the task, absolute timing error was significantly greater in the DCD group. The most robust chronometric effect for differentiating the two groups seemed to be the duration of movement when the target was small. Multiple regression showed that TOMI was a powerful indicator of movement duration.
