Coupling of the reach and grasp phase during catching in children with developmental coordination disorder.

Full Abstract

The authors studied 2-handed catching behavior in 10 children with developmental coordination disorder (DCD), aged 7-10 years old, and their typically developing peers (TDC). Participants performed 15 catches, and the authors examined kinematics of both transport and grasp phases. In terms of the transport phase, movement initiation and movement time was longer and peak deceleration was earlier in children with DCD. In addition, such children initiated the grasp phase earlier, and their maximal grasp aperture was larger. In children with DCD, the time to maximal grasp aperture was more variable, and that aperture was earlier when the authors examined it with respect to the transport phase of the catch. The data suggest that children with DCD may use a decomposition strategy to simplify the movement control of the transport and grasp phases of a catch.
