Abstract Purpose: Exercising in water and on land has a positive effect on improving of the symptoms of herniated lumbar disc. Visualization can also positively influence the treatment of some diseases, the effect of visualization on the treatment of lumbar disc herniation has not yet been investigated. Therefore, the aim of the study is to compare the effects of visualization correction during exercises in water and on dry land on balance, pain and disability of women suffering herniated lumber disc. Materials and Methods: This research is conducted on 24 women with lumber disc herniation, average age 35 to 45 years, who were randomly divided into two groups, experiment 1 and experiment 2. Before and after training, pain and disability and balance were measured by Quebec questionnaire, Oswestry standard questionnaire and Biodex balance device, respectively. The training program was carried out for six weeks, three sessions per week and 20 to 30 minutes per sessions. One training group carried out visualization in the water and the other group on land. Then the data was analyzed by using the repeated measures analysis of variance method at a significance level of P < 0.05. Results The results showed that both visualization procedures significantly improved pain severity (P=0.001) and disability (P≤0.05), in within groups in experimental 1 and 2 groups. However, there was no significant effect on balance (P>0.05). Furthermore, no significant difference was found between the two groups for any of the variables measured (P≤0.05). Conclusion It may be concluded that the visualization of exercises in water and on land has a positive effect on improving pain and disability, but no effect on improving balance. Perhaps balance would improve if the exercises were performed face-to-face. Also, visualizing exercises in water and on land probably has the same effect on improving people\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s pain and disability
