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 compare the effects of three types of balancetraining: single task, dual task under fixed priority instructional set (Fp) and dualtask under a variable priority instructional set (Vp) on the balance of the elderly.The participants were 36 elderly over 65 years old from Kerman province whowere randomly divided into three groups (each 12 subjects) based on Burg pretestscores. The groups included single task, dual task under fixed priority and dualtask under variable priority. Experimental groups received 45 minutes of trainingsession, 3 sessions a week for 4 weeks. For data analysis, ANCOVA andBonferroni post hoc test were used at (P≤0.05). The results showed that asignificant difference between single task and dual task under fixed priority groupsand also between single task and dual task under variable priority (P=0.008 andP=0.000 respectively). There was no significant difference between dual task underfixed priority and variable priority groups (P=0.149). In addition, the results inTug test under dual task condition showed a significant difference between singletask and dual task under fixed priority groups and also between single task anddual task under variable priority groups and also between dual task under fixedand variable priority groups (P=0.035, P=0.033, P=0.000 respectively). Theresults showed that single and dual task balance training improved balanceperformance in the elderly but those who had training under dual taskoutperformed under single and dual task conditions.
