Comparison two Treatment Method of Static Stretch Exercises and Conventional Physiotherapy on Dynamic Balance in Patients With Chronic Low Back Pain Caused by Shortened Hamstring Muscle

Introduction: Low back pain is one of the most problems that people are engaged nowadays. In most of these patients Hamstring muscle shortening is usual. In these patients may control postural index decreased and cause balance disorders. The aim of this study was to compare two treatment methods of static stretch exercises and conventional physiotherapy on dynamic balance in patients with chronic low back pain.

Methods: 16 low back pain patients with shortened hamstring were enrolled in the study. They were allocated randomly in either conventional physiotherapy treatment group or to physiotherapy plus hamstring sustained stretch group. Before and after 12 treatment sessions, hamstring muscle flexibility using active knee extension test and body balance using Y test for balance were assessed. Statistical analysis was done using SPSS version 21.

Results: Dynamic balance increased significantly) P<0.05(in both groups, but no significant difference was seen between two groups) P≥0.05 (.Range of the active knee extension in test after the intervention has increased significantly) P≤0.05), while there was no significant difference in the department of physiotherapy (P≥0.05 (.

Conclusion: Both conventional physiotherapy and physiotherapy plus sustained stretch improved dynamic balance and hamstring flexibility, but there was no difference between two treatment groups.
