Dysfunctional anticipatory and feedback responses

         It is a well-known fact that effective postural stability requires two different and integrated central processes, such as sensory organization and motor response organization (Nashner et al., 1989).  Sensory organization gives the individual orienting sensory feedback from somatosensory, visual and vestibular information. This information is interpreted within the central nervous system (Grove et al., 2007). The motor response organization process includes the execution of coordinated and scaled neuromuscular responses to either both internal and/or external perturbations of the center of mass (Nashner et al., 1989).
         A study done by Grove et al. (2007), examined the sensory organization of postural stability in children with DCD by analyzing their ability to rely to changing degrees on The data shows that as a whole, children with DCD demonstrated significantly impaired static balance under conditions where vestibular feedback was the only accurate source of orienting feedback for postural control (Grove et al., 2007). It is also important to note that half of the children with DCD displayed static postural instability that was greater during inaccurate visual feedback conditions compared to conditions where visual feedback was absent (Grove et al., 2007).  This study showed findings that were aligned with the findings of Geuze (2003,2005), which states that children with DCD had trouble with static balance only in challenging or new situations such as a condition where the use of vestibular feedback for sensory re weighting and altering the postural control strategy are quite advantageous (Grove et al., 2007). The following sections will discuss current as well as novel therapeutic techniques to improve static postural stability in children with DCD.
