For obese patients with low back pain, Aquatic exercises are more beneficial for dealing with pain,Improved Strength, increase Flexibility.This study aims to evaluate thetherapeutic effects of aquatic exercises for low back pain in obese population.Methods:A observational study was conducted for 80 obese patients with history of low back pain. Patients age was between 30 to 60. and population was selected under grade I BMI i.e. 30 to 34.9, participants were assigned to either two groups depends on pain scales. Demographic data, pre intervention readings and post intervention readings were collected with help of pain scales. Pain scales included Oswestrylow back disability questionnaire and visual analogue scale, these scales will help to find out the outcomes of pain and flexibility, and functional activities.Results:The study included80 obese individuals, evenly distributed between two groups, that is40 low back pain obese populationrandomly selectedfor Oswestry low back disability questionnaire and 40 patients for the visual analogue scale,initial measurements collected. Post intervention the aquatic exercises theshowed significant improvement in the both the pain grading scales, in the Oswestry low back disability questionnaire in pre intervention 95% population was severe disability shifted to mild or moderate disability category.Where as in the visual analogue scale drastically decreased pain scores severe to mild pain level.Conclusion:Both the scales after calculating pain scores significantly improved in the pain scores, The Chi-Square test shows a statistically significant difference between the Pre and Post intervention groups (p<0.05), with a p-value of.000. with in the both pain scales. This indicates that the decreasespain levels significantly about 48% anaverage.That means aquatic exercises are significantly showed the pain decreasing levels.
