The purpose of this study was to investigate the effect of cognitive rehabilitation on Fundamental motor skills of children with DCD. The method of the present study was quasi-experimental, a pre- posttest design with experimental, and control groups. The statistical population of the study was 6 to 10 year old children in khonj city. For this purpose, 40 children with developmental coordination disorders were selected by cluster sampling method based on entry and exit criteria as members of the sample group and were randomly divided into experimental (n = 20) and control (n = 20) groups. Electrical stimulation was performed in 24 sessions and each session for 20 minutes with an intensity of one mA on the F3 and F4 regions on the study groups. The instruments used in this study included the DCD Questionnaire (DCDQ7), Movement Assessment Battery for Children - Second Edition (MABC-2), the Ulrich Test of Gross Motor Development (TGMD-2) and the Raven Intelligence Test. Data analysis was performed by Levin, Kolmogorov-Smirnov test and analysis of covariance at a significance level of 0.05. The results showed that Transcranial Direct Current Stimulation (tDCS) have a significant effect on increasing locomotor movement skills (F = 461.84, P = 0.001, Eta = 0.92), object control (F = 351.15, P = 0.001, Eta = 0.90,) and total motor skills (F = 597.21, P = 0.001, Eta = 0.94). This method can be useful and effective in improving Fundamental motor Skills, which is one of the major problems of these children.

The aim of this study was to investigate the effect of a selected balance training program under dual and single-task conditions on working memory of children with developmental coordination disorder. The research method was semi-experimental and a pre-test-post-test- follow-up design with a control group. In this study, 39 boys with DCD were selected by the available sampling method and randomly assigned to three groups: Dual-task training (n=13), single-task training (n=13), and control (n=13). The two experimental groups performed a selected training program with two different conditions for 8 weeks. All subjects were evaluated in three stages of pre-test, post-test and follow-up test (two months after post-test) by the Corsi block-tapping test (working memory test). Data analysis using ANOVA with the repeated measure as well as one-way ANCOVA showed that in the post-test, working memory in dual-task group was superior to both single and control groups (P <0.05). Also, a significant difference was observed from pre-test to post-test in all experimental groups except the single task group in the extended block index and the control group. In the follow-up test, this superior was maintained only in the overall score index and the overall effort. Also, the single-task group was superior to the control group in the post-test (P <0.05). Due to the importance of executive function, using this selected exercise program to improve working memory can be a useful tool and is suggested for this group of children.

The aim of this study was to investigate the effect of game-oriented exercises on motor development of overweight children with developmental coordination disorder. The research method was semi-experimental with pretest and posttest. 50 overweight children aged between 8 and 10 with developmental coordination disorder were selected and were randomly assigned to experimental (n=35) and control (n=15) groups after pretest. The experimental group participated in the protocol for 3 sessions per week during 3 months. MABC-2 test was used and SPSS 21 software was used for data analysis. The results of MANCOVA showed a difference between the experimental and control groups in at least one of the variables. Based on the results of one-way covariance analysis with a significance level of 0.05, there was a significant difference between the control and the intervention groups in motor development components and its subscales (hand speed, targeting and balance) and the experimental group got better scores. Therefore, it is recommended that the development of this disorder should be prevented in overweight individuals by designing different exercises and early intervention, and have a positive effect on their motor development.

Children with developmental coordination disorder (DCD) sometimes have difficulties in performing and learning motor skills. The aim of the present study was to investigate procedural motor acquisition and learning in DCD children. 12 children with developmental coordination disorder and 12 normal children with matched IQ and chronological age were selected from 8-12-year-old male students of Tabriz city by purposive sampling method. A modified version of rotary pursuit task and variables of total time on target (TOT), consecutive time on target (CTT), distance from the target (DT), distance from the path (DP) and relative phase were used to assess procedural motor learning. After training in the acquisition phase, subjects participated in the immediate 10-minute retention test and the consolidation test after 24 hours of rest. Analysis of data by analysis of variance with repeated measures showed no significant differences between the two groups in TOT, DP, and relative phase in the acquisition phase, but there were significant differences in CTT and DT. There were significant differences in TOT, CTT, and DT in the retention phase, but there was no significant differences in DP and relative phase. Generally, the results suggested that despite the low performance of their procedural motor learning, DCD children were able to acquire motor coordination patterns.

The aim of this study was to investigate the possible effects of gymnastics training on some neuropsychological functioning in male children with developmental coordination disorder aged between 8 and 10 in Tehran city. 34 children with developmental coordination disorder who aged between 8 and 10 and had referred to the clinics of occupational therapy and rehabilitation in Tehran in 2013 were selected using convenience and purposive sampling method and were randomly divided into experimental (n=19) and control (n=15) groups. For screening, Developmental Coordination Disorder Questionnaire and Raven's progressive matrices test were used. The dependent variables were assessed by Neuropsychological Conner Questionnaire. The experimental group received an 8-week (3 sessions per week, each session 45 min.) locomotor intervention of gymnastics protocol. Statistical analysis was performed using multivariate covariance analysis at P≥0.05 with SPSS16 software. The findings showed significant differences between control and experimental groups in all variables of executive functions (P≤0.001, F= 492.454a) and sensory – motor function (P≤0.001, F=285.693a). Accordingly, it can be concluded that gymnastics training can improve neuropsychological functioning in children with developmental coordination disorder.
