Purpose: Previous study (Chung & Stoffregen, 2011) has shown that the coupling of DCD children with optic tic flow differed from that of typically developing (TD) children. The study further investigated the differentia l sensitivity of TD and DCD children to imposed optic flow using the moving room paradigm. Methods: A total of twenty children, ten with DCD (< 5th percentile in M-ABC test) and ten matched controls, in the age of 10-11 years (mean age = 9.5 ± 0.6 yr) participated in this study. We evaluated the postural sway of TD and DCD childrenwhile providing and reducing support rigidity with the vision or without during the cyclic oscillation of visual stimulus. The room was oscillated with magnitude 2 cm at three different frequencies (0.1 Hz, 0.2 Hz, 0.3 Hz). Variation in the frequency of room oscillation was crossed with variation in the support surface (foam vs. no foam), for both TD and DCD children. We measured the motion of the body in the anterior-posterior axis of center of pressure(COPap), that is, along the line of sight. Results: The postural sway of DCD children was less stable than TD children without room motion. In addition, DCD children displayed greater body sway (high mean gain, high max spectrum ) during periodic oscillation of room motion. The group differences were large during supported surface. Conclusion: We concluded that DCD children may have problem in integrating multi-sensory information and use of optic flow differently from TD in controlling their posture.
