The purpose of this study was to examine the effect of motor imagery practice through and after observation on static balance. Methodology: Movement Imagery Questioner Revised (MIQ_R), was used and 24 girl students (age=15-17) with top imagery ability( high scores in Movement Imagery Questioner Revised) selected and matched randomly in two groups ,imagery after observation and imagery through observation groups. The stork test was used to determining the subjects static balance in two stages, before and after six sessions (intervention) by both groups. Data were analyzed by ANOVA 2*3 and paired t-test (p<0.05). Finding: Result indicated the time of maintaining the static balance ingroup that have imagery after observation significantly was better than group that have imagery through observation. Conclusion: These findings suggest that imagery after observation is the effective factor in the time of maintaining the static balance in 15-17 years old.
