In this study, we aimed to investigate the effect of eight weeks of aquatic and terrestrial trainings on the functional balance and psychological factors of spastic cerebral palsy girls.<br> <strong>Methods:</strong> This semi-experimental study was conducted based on a pretest-posttest design. We investigated 19 girls with diplegia and quadriplegia spastic cerebral palsy who aged from 8-15 years and lived in Yazd, Iran. The participants were selected based on the available population and categorized into two groups of terrestrial training (N = 10) and aquatic training (N = 9). Both groups received training for eight weeks (three times a week). In order to evaluate the participants&rsquo; functional balance, Berg&rsquo;s functional balance test was performed for both groups before and after the intervention. In addition, Depression Anxiety and Stress Scales (DASS-21) were applied to study the psychological factors of both groups before and after the intervention. To analyze the data, the Shapiro-Wilk test, independent t-test, and dependent t-test were used.<br> <strong>Results: </strong>The results showed that both terrestrial and aquatic training groups improved considering functional balance, but this improvement was just significant in aquatic training group (P=0.042). However, no significant difference was observed in the psychological factors as well as depression, anxiety, and stress.<br> <strong>Conclusion:</strong> We suggest aquatic trainings to improve the functional balance.</div> Cerebral palsy, Balance, Anxiety, Stress 125 132 http://fdj.iums.ac.ir/browse.php?a_code=A-10-134-1&slc_lang=en&sid=1 Elahe Akbar elaheh.akbar@gmail.com 10031947532846001704 10031947532846001704 No Occupational Therapist, Comprehensive Psychiatric Center, Shahid Sadoughi University of Medical Sci-ences, Yazd, Iran.
