摘要：The purpose of the present study was to determine the effect of 6-weeks hydrotherapy on some of the selected parameters related to Kyphosis in kyphotic girls. After sampling and diagnosing the kyphotic girls at the Azad University, 10 subjects were selected. All subjects participated in 18 sessions, three times a week and each time half an hour per session. The dependant variables were involved: back muscles power, spine flexibility, chest expansion, shoulder abduction movement extension which they were measured by dynamometer, goniometer, and strip meter before and after exercise. Data was analyzed by descriptive statistic and dependent T-test at the significant level of (α=0/05) and following results were concluded: The result showed that there was a significant difference between post-test in comparison with pre-test for the back muscles power (p≤0/05), shoulder abduction movement (p≤0/05) spine flexibility and the chest expansion (p≤0/05). In comparison with pre-test, it has been shown an increase in value of all dependent variables after the hydrotherapy.
