Introduction: Balance in individual with intellectual disability has a great importance due to the failure to perform motor tasks. The purpose of the present study was to compare postural control and balance function in two groups of individual with intellectually disabled with and without developmental coordination disorder. Methods: The present study was a cross-sectional and causal-comparative. The statistical population of this study included all students with intellectually disabilities studying in an exceptional school in Rasht in 2019. According to the inclusion and exclusion criteria, 52 people, including 32 students with intellectual disabilities with developmental coordination disorder and 20 students with intellectual disabilities without developmental coordination disorder were purposefully selected. BESS test, Y balance test, Timed Up and Go (TUG) test were used to evaluate postural control, dynamic balance and functional balance, respectively. For statistical analysis, SPSS version 16 software, independent t-test and Mann-Whitney U tests at a significance level of P <0.05 was used. Results: Based on the results of the present study, a significant difference was observed in functional balance (p = 0.001), and overall score of postural control (p = 0.003), but no significant difference in dynamic balance (p <0.05) was observed between the two groups. Conclusion: Developmental coordination disorder is highly prevalent among the individual with intellectual disabilities. At the same time, they have poorer postural control and functional balance compared to their peers without developmental coordination disorder. Due to the importance of controlling posture and maintaining proper balance in order to prevent injury of these people who are less physically fit than their peers, it is recommended to sports coaches, occupational therapists, physiotherapists and other related fields to take a variety of balance programs to emphasize on improving their balance.

Coordination Disorder

Little research has been produced about literacy readiness in Kindergarten children at risk for  Developmental Coordination Disorder (DCD), despite this age being one of the most important epoch of motor and cognitive development. In this study we compared pre-literacy skills in Kindergarten children at risk for Developmental Coordination Disorder (DCD) with Typically Developing (TD) children. Participants were 26 Italian children, who had a mean age of 5.1 years, 13 at risk for DCD and 13 TD attending kindergarten schools. Pre-literacy abilities were measured trough tasks derived by the Italian PRCR-2 battery: Semi-circles (A and B), Letter identification and Object Naming Time. Significant differences were found between children at risk for DCD and TD children on tasks of visual memory of printed signs, visual analysis ability, visual discrimination and attention and sequentiality of eye movements. Findings suggest the need to implement pre-school cognitively challenging motor activities programs to enhance manual dexterity, aiming and catching skills as well as static and dynamic balance at early age Little research has been produced about literacy readiness in Kindergarten children at risk for  Developmental Coordination Disorder (DCD), despite this age being one of the most important epoch of motor and cognitive development.

Coordination Disorder

Developmental coordination disorder (DCD) occurs in a small number of children who present with impaired body/eye coordination. No study of ophthalmic function in DCD exists despite vision’s primary role in perception. Ocular performance was therefore assessed with a battery of tests. Five hundred children aged between 5 and 7 years were involved in the study. Diagnosis of DCD was confirmed for 29 children by the Movement Assessment Battery for Children (ABC); 29 control children were randomly selected. Comprehensive examination with a battery of ophthalmic tests did not reveal any significant difference in visual status between the two groups. Strabismus was found in 5 children from both groups. All 5 children with strabismus from the DCD group showed a similar movement profile with the Motor Competence Checklist. While a causal relationship cannot be discounted, the presence of strabismus appears more likely to be a “hard” neurological sign of central damage common to this group. The evidence seems to indicate that a simple ophthalmic difficulty does not explain problems with movement control.

Coordination Disorder

Safe stair negotiation is an everyday task that children with developmental coordination disorder (DCD) are commonly thought to struggle with. Yet, there is currently a paucity of research supporting these claims. We investigated the visuomotor control strategies underpinning stair negotiation in children with (N = 18, age = 10.50 ± 2.04 years) and without (N = 16, age = 10.94 ± 2.08 years) DCD by measuring kinematics, gaze behavior and state anxiety as they ascended and descended a staircase. A questionnaire was administered to determine parents' confidence in their child's ability to safely navigate stairs and their child's fall history (within the last year). Kinematics were measured using three-dimensional motion capture (Vicon), whilst gaze was measured using mobile eye-tracking equipment (Pupil labs). The parents of DCD children reported significantly lower confidence in their child's ability to maintain balance on the stairs and significantly more stair-related falls in the previous year compared to the parents of typically developing (TD) children. During both stair ascent and stair descent, the children with DCD took longer to ascend/descend the staircase and displayed greater handrail use, reflecting a more cautious stair negotiation strategy. No differences were observed between groups in their margin of stability, but the DCD children exhibited significantly greater variability in their foot-clearances over the step edge, which may increase the risk of a fall. For stair descent only, the DCD children reported significantly higher levels of state anxiety than the TD children and looked significantly further along the staircase during the initial entry phase, suggesting an anxiety-related response that may bias gaze toward the planning of future stepping actions over the accurate execution of an ongoing step. Taken together, our findings provide the first quantifiable evidence that (a) safe stair negotiation is a significant challenge for children with DCD, and that (b) this challenge is reflected by marked differences in their visuomotor control strategies and state anxiety levels. Whilst it is currently unclear whether these differences are contributing to the frequency of stair-related falls in children with DCD, our findings pave the way for future research to answer these important questions.

Coordination Disorder

Developmental coordination disorder (DCD) refers to the motor skill difficulty without any explainable medical conditions. The prevalence rate of DCD is estimated to be 5–12% in Taiwan. Balance deficit is one of the main characteristics of children with DCD. The aim of this study was to examine the effect of a self-developed balance training program on the balance performance in children with DCD. Twenty four children aged 5–10 years old with DCD and 12 age-matched typically developing (TD) children participated in the study. Children with DCD were randomly divided between an experimental group (DCD-exp) who received treatment with the iBalance training program and the control group (DCD-con) who did not received treatment. TD children also did not receive treatment as a comparison group. All the children were tested with the movement assessment battery for children-2nd edition (MABC-2) and iBalance assessment system before and after the intervention period. A significant improvement of the MABC-2 balance component score, time duration of one-leg standing and the number of success trials with dynamic balance tasks were noted in the children of DCD-exp but not in the children of DCD-con and TD. The results suggest that the iBalance training program is effective for a short time treatment effect for children with DCD. The long term effect and transfer effect need to be examined.
