Introduction: CTherefore, the present study was conducted to investigate the effect of virtual reality training on gross and fine motor skills in children with developmental coordination disorder.
Methods: In this semi-experimental study with a repeated measures design, 24 boys aged 7 to 10 years from Tehran diagnosed with developmental coordination disorder (DCD) were selected based on inclusion criteria and randomly assigned to two groups: virtual reality training and control. Participants completed the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2) at pretest. The intervention phase lasted six weeks, with three 20-minute sessions per week, during which the virtual reality group performed the prescribed training program while the control group engaged in their usual daily activities. A posttest was conducted in the final session. Follow-up assessments were performed one day and 42 days after the posttest to evaluate short-term and long-term effects, respectively. Data were analyzed using repeated measures analysis of variance (ANOVA).
Results: The results showed that virtual reality training led to a significant improvement in both gross and fine motor skills in children with developmental coordination disorder (DCD) (p < 0.05). Additionally, the findings indicated that the improvements in gross and fine motor skills were maintained in both short-term and long-term follow-up tests (p < 0.05).
Conclusion: Based on the results, virtual reality training can likely be used in clinical and home programs to improve gross and fine motor skills in children with developmental coordination disorder (DCD), as it can stimulate interest and promote active participation.

The aim of this study was to evaluate the effectiveness of transcranial direct current stimulation (tDCS) on working memory in children with developmental coordination disorder (DCD). The research method was quasi-experimental with pretest and posttest and retention with experimental and control groups. The research population consisted of children (age: 7-11 years old) in Urmia city in 2018. 16 children with DCD were selected as the sample with convenience sampling method and based on inclusion and exclusion criteria, and then were randomly divided into two groups: experimental (n=8) and control (n=8). The experimental group received 10 sessions (each session 10 minutes) of tDCS on f4 and f3 brain zones with 0.75 mA circuitry. The control group received 10 sessions of sham circuitry for 20 seconds, then the circuity was cut off, but they were not informed of this sham circuity. The data of working memory were collected using N-BACK test. The analysis of variance with repeated measurements was used to test the research hypothesis (P=0.05). The results showed that transcranial direct current stimulation (tDCS) had a significant effect on the enhancement of working memory and the effect would continue to the retention phase (P=0.05). This approach can be used to improve working memory in children with DCD.
