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=9.36 years +/- 0.68) and 13
Controls ( x=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.
