The aim of this study was to investigate the effect of mental imagery and physical practice on dynamic balance in male patients with multiple sclerosis. This study was semi-experimental and the statistical population included male patients with multiple sclerosis in Ahvaz city in 2012 (N=300). For sampling, Visual and Kinesthetic Imagery Questionnaire and EDSS scale were used. Finally, 33 patients with similar ability of imagery and moderate disorder in EDSS Scale were selected and randomly assigned to 3 groups: mental imagery-physical practice (n=11), mental imagery (n=11) and physical practice (as control group, n=11). The TUG test was used to assess dynamic balance in the pretest, posttest and retention test. The training protocol consisted of 3 sessions a week for 6 weeks. Posttest was performed 2 weeks after the last session of the training protocol. After investigating the data normality and variance equality, data were analyzed using one-way analysis of variance with repeated measures, one-way analysis of variance and Tukey post hoc test. The results indicated a significant difference in posttest (P=0.02) and retention (P=0.003) phases among the groups, and combined group had a better performance than the other groups during both phases. According to these results, mental imagery can be used as a practical method for the better performance of dynamic balance in patients with multiple sclerosis.

Abstract
The aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). The training ...

The aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). The training protocol was performed three sessions a week for 6 weeks. Data analysis indicated a significant difference between the groups in acquisition (P=0.001) and retention (P=0.002) phases. The results of Tukey post hoc test in the acquisition phase indicated no significant differences between cognitive specific imagery group and cognitive general imagery group (P=0.53) but there were significant differences between cognitive specific imagery group and traditional imagery group (P=0.006) and also between cognitive general imagery group and traditional imagery group (P=0.03). Also, in the retention phase, the results of Tukey post hoc test indicated significant differences between cognitive specific mental imagery group and traditional mental imagery group (P=0.002), between cognitive specific mental imagery group and cognitive general mental imagery group (P=0.037) and between cognitive general imagery group and traditional imagery group (P=0.001). With regard to the findings, the role of the cognitive specific imagery was in the center of attention more than before and soccer instructors and coaches are recommended to use this type of imagery.
