The Effects of Eccentric Training and Static Stretching Exercise of Hamstring on Pain intensity, Oswestry disability Questionnaire, Flexibility and Range of motion in Patients with Low back pain

Objective: The purpose of this study was to compare the effects of eccentric training (ET) of hamstring and static stretching (ST) exercise on the pain intensity (VAS), Oswestry disability Questionnaire (ODQ), flexibility, and range of motion (ROM) in lumbar region of patients with low back pain (LBP). Method: ET (n=9) and ST (n=9) groups were received intervention 3 times per week for 3 weeks. A VAS, ODQ, flexibility of hamstring, ROM in lumbar region were measured before and after interventions for each group. A paired t test was used to compare variables before and after intervention between groups, and the independent t test was used to compare variables before and after intervention between groups, and the significance level was p<.05. Results: Both the hamstring eccentric training group and static stretching group showed a statistically significant decrease in the VAS, ODQ (p<.05), and sit and reach test value in the static stretching group was statistically significant increased (p<.05). There were no significant difference in VAS, ODQ, Flexibility, ROM between the two groups before and after intervention. Conclusion: These results suggest that Eccentric training and static stretching intervention of hamstring are effective method to improve the VAS, ODQ of patients with LBP.
