Several lines of evidence indicate that the hydrotherapy could rehabilitate the disc herniation. Relatively limited number of studies describe the effects of hydrotherapy exercises on rehabilitate the lumbar disc herniation in females. The purpose of these studies was to determine the interrelation between the hydrotherapy exercise programs and rehabilitate the mild-moderate lumbar disc herniation on female patients. We examined the hydrotherapy exercise program and crawl style swimming training on some study variables of the volunteers, they were divided equally into two groups: experimental group (n=7 females; aged 54.857 ? 3.848) control group (n=7 females; aged 54.143 ? 3.848). To evaluate the effect of both programs on our subjects we measured each of Abdominal Fat by fat caliper, Forward Range of Motion and Backward Range of Motion by the protractor, the Back Muscles Strength by the Dynamometer, Pain Intensity with visual analogue scale (VAS) and Daily Activity by SF-12. The results were by comparing the pre and posttests of each group, and comparing differences between the posttests for the control and experimental groups. Participants of this study were a mild-moderate lumbar disc herniation female patients. The results of the Crawl Style Swimming Training was there is a statistically significant differences at the level of (p<0.05) between the pre and posttests of the control group in favor of posttests. And results the Hydrotherapy Exercise Program was there is a statistically significant differences at the level of (p<0.05) between the pre and posttests of the experimental group in favor of posttests. And there is a differences between the posttests averages for the control and experimental groups in favor of the experimental group. We demonstrated that the hydrotherapy exercise program rehabilitate the mild-moderate lumbar disc herniation in female patients.
