“…Their somatosensory, visual and vestibular ratios were all below the norm. Grove and Lazarus (2007) replicated Inder and Sullivan's testing methods with a larger sample (16 and 14 children in the DCD and control groups, respectively) and found that the ability to utilize vestibular information for balance was ineffective (significantly lower vestibular ratio) in children with DCD. Somatosensory and visual inputs were therefore weighted more heavily in postural control.…”

“…Previous studies have reported that 73-87% of children with DCD have balance problems (Macnab, Miller, & Polatajko, 2001). Their suboptimal balance is important and needs to be tackled, because any impairment in postural control may limit the children's activity and participation, increase the risk of falling and injury, and affect their motor skills development (Fong, Lee, & Pang, 2011;Grove & Lazarus, 2007).…”

“…A few studies have examined sensory organization for balance control in children with DCD but the results have been inconsistent (Cherng, Hsu, Chen, & Chen, 2007;Grove & Lazarus, 2007;Inder & Sullivan, 2005;Przysucha & Taylor, 2004). For example, Inder and Sullivan (2005) first reported wide-spread impairment in sensory organization in four children with DCD using computerized platform posturography.…”

The postural control of children with and without developmental coordination disorder (DCD) was compared under conditions of reduced or conflicting sensory input. Twenty-two children with DCD (16 males, 6 females; mean age 7 years 6 months, SD 1 year 5 months) and 19 children with normal motor development were tested (13 males, 6 females; mean age 6 years 11 months, SD 1 year 1 month). Standing balance, sensory organization and motor control strategy were evaluated using the sensory organization test (SOT). The results revealed that children with DCD had lower composite equilibrium scores (p<.001), visual ratios (p=.005) and vestibular ratios (p=.002) than normal children in the control group. No significant between-group difference in their average somatosensory ratio was observed. Additionally, children with DCD had lower motor strategy scores (swayed more on their hips) than the normal children when forced to depend on vestibular cues alone to balance (p<.05). We conclude that children with DCD had deficits in standing balance control in conditions that included reduced or conflicting sensory signals. The visual and vestibular systems tended to be more involved in contributing to the balance deficits than the somatosensory system. Moreover, children with DCD tended to use hip strategy excessively when forced to rely primarily on vestibular signals to maintain postural stability.

“…37 Moreover, the literature emphasized that as worse was the motor performance, the lower was the self efficacy. 39 Hence, when SPD is coupled with ineffective motor control among children with DCD it may enhance their difficulties in gross motor as well as in fine motor performance, reduce their ability to adaptively function in daily activities 25,40,41 and to feel competent.…”

Sensory processing difficulties (SPD) and their relation to motor performance and to child's perceived competence among children with developmental coordination disorders Submit Manuscript | http://medcraveonline.com Literature reviewDevelopmental coordination disorders (DCD) affect approximately 6% of school aged children and significantly impair their activities of daily living and their academic performance. These impairments are not explicable by age, IQ or neurological condition.1,2 Some studies suggest that deficits in motor coordination among children with DCD could be related to sensory processing difficulties (SPD) affecting their motor acuity and their perceptual processes. 3,4The phenomenon of SPD is known to be prevalent among 5-15% of the population.5 SPD represent the inability of the central nervous system to modulate the degree, intensity, and nature of responses to sensory input. Thus, SPD may result in sensory hyper or hypo sensitivity.6 Individuals with hypersensitivity have low neurological threshold to sensation and thus respond to sensation faster, with more intensity for a longer duration. 7 They may experience non aversive stimuli as painful and thus express aggressive behaviours, withdrawal, irritability, moodiness, and poor socialization. On the other hand, individuals with sensory hyposensitivity have high neurological threshold to sensation and thus experience difficulties in detecting incoming sensory information. They are described as unmotivated or self-absorbed. Some people with hyposensitivity counter act to their high neurological threshold and actively seek for rich sensory stimuli -they enjoy rich sensory environment and actively initiate behaviours that create sensations. 8Studies that focused on SPD among children with DCD referred to specific modalities -mainly to the visual and to the vestibular sensations. Wilson & McKenzie 9 highlighted that visual-spatial processing; kinaesthetic perception and cross-modal integration in DCD may be impaired and affect children's movement performance. Indeed, visual-spatial processing and visual-kinesthetic integration which are prerequisites for motor control and stability are impaired AbstractObjective: Movement is dependent on sensory input. Both Developmental Coordination Disorders (DCD) and sensory processing difficulties (SPD) may reduce child's self-competence and daily function. However, the knowledge about SPD among children with DCD and their relation to their motor performance and selfcompetence is scarce. This study aimed to (1) compare sensory processing abilities and self competence between children with DCD and typical controls (2) examine the relationship between SPD, DCD severity and child's perceived competence among children with DCD. Methods:The study included 90 children aged 4-10 years: 32 children with DCD and 58 typical controls. All children performed the Movement Assessment Battery for children (M-ABC). Those who scored lower than the 15% on the M-ABC were included in the study group. The parents of all child...

“…performance in these children, Grovea and Lazarusb (2007) assessed 30 children with and without DCD. It was found that children with DCD had greater difficulty maintaining postural control when visual and somatosensory feedback were compromised in sensory conflict environments (p = .031).…”
