Low back pain (LBP) is one of the most common complaints seen in primary care, with 60-85% of adults experiencing it at some time in their lives. Athletes are no exception, with the added strain of long training contributing to the problem. Current studies have done to see the effect of core strengthening exercises using Swiss ball, theraband and floor exercises in general population with low back pain, but there are no studies which have compared the effectiveness of Swiss ball, theraband and floor exercises in core strengthening in cricketers with low back pain. Objective: study and compare the effectiveness of Swiss ball exercises, theraband exercises and floor exercises in cricketers with low back ache in terms of pain and back strength. Methods: Study Design: Randomized Clinical Trial Sample: Male and Female cricketers with low back ache. Sixty competitive cricket players between the ages 18 to 35 years were randomly assigned to 1 of 3 groups. Swiss ball (n=30), theraband (n=30) and floor exercises Baseline pain and back strength was taken pre treatment i.e. 1st day and post Treatment. VAS was used to assess pain. Comparison of data within group and between groups of the pre and post values was done. Results: The results revealed that within group analysis in all the three groups showed statistically significant improvement in terms of pain and back strength (p<0.005). Whereas when between groups was analysed, Group B (theraband and floor exercise) showed significant improvement when compared to Group A (Swiss ball and floor exercise) and Group B (floor) showed significant improvement Conclusion: Although the study showed beneficial results in all the 2 groups, but the results reflected that theraband group had better improvement than the other two groups which was measured in terms of strength improvement and pain reduction
