    Abstract

    Purpose: To quantify two-handed catching in boys with Developmental Coordination Disorder (DCD) by examining sequencing of the upper limb and trunk segments, and degree of symmetry.Method: Thirteen boys with DCD ((x) over bar = 9.36 years +/- 0.68) and 13 Controls ((x) over bar = 9.16 years +/- 0.68) participated. Children performed 10 two-handed central catching trials, with the best five trials selected for analysis.Results: The DCD group displayed greater variability in range of motion across all joint rotations in the catch phase. Specifically, increased shoulder flexion, thorax extension and elbow extension. Although the initiation of segmental movement occurred in the same order for the two groups, the DCD group initiated wrist extension considerably earlier. The DCD group also exhibited significant asymmetry in elbow flexion-extension.Conclusion: Despite success in performing this simple catching task (88% successful), the DCD group displayed an inefficient, variable and less symmetrical catching technique.
