This study aimed to investigate the effect of 8 weeks of perceptual–motor training on bimanual coordination performance and static and dynamic balancing in students with hearing impairment aged 8–11 years in Kermanshah. 20 girls with hearing impairment with a mean age of 9.35 ± 1.42 were randomly selected and divided into control and experimental groups. The used tools in this study were continuous bimanual coordination test device, stork balance test, and Y dynamic balance test. First, all participants performed bimanual coordination task, and static and dynamic balance tests as pretest. Then, the experimental group performed the exercise training (such as static and dynamic balancing, throwing and catching a ball, running between obstacles) for 8 weeks, 3 sessions per week, and 60 min per session and finally posttest was applied for both groups. After ensuring the normal distribution of data using the Shapiro–Wilk test, t test was used to analyze intra-group and inter-group differences at a significance level of P < 0.05. The results showed an increase in static (P = 0.0011), and dynamic (P = 0.0206) balancing, and bimanual coordination (P = 0.0031), improvement after 8 weeks of perceptual–motor training in the experimental group. According to the obtained results, it can be concluded that exercise training was effective in improving motor skills, as well as the use of these trainings is recommended to increase the level of motor performance.
