Effect of Strength Training and Usual Physiotherapy Treatment on the Flexibility of Hamstring Muscle in Patient with Chronic Low Back Pain

Introduction: High prevalence of low back pain and its related disability in doing daily activities and Impairment in social activities will have a bad effect on patients and the society. So the aim of this study was to evaluate the Effect of Strength Training and Usual Physiotherapy Treatment on the Flexibility of Hamstring muscle.

Methods: This study was applied. 16 low back pain patients with shortened hamstring were enrolled in the study and were divided into two groups. They were allocated randomly in either usual physiotherapy treatment group or to usual physiotherapy treatment plus hamstring strength training in long length group. Before and after the 12 sessions were measured length of hamstring muscle with a goniometer and inclinometer and flexibility of dorsal and hamstrings muscles with Sit and reach test. Statistical analysis was took place by paired and independent t-test method using SPSS version 21 (P≤ 0.05(.

Results: These findings suggest that both groups had significant increase in outcomes flexibility of dorsal and hamstrings muscles test (P≤ 0/05). But there were no differences in variables between two groups. Length of hamstring muscles showed significant increase only in the strength group with SLR after a course of treatment (P≤ 0.025).

Conclusion: According to the results of this study can be concluded that In general adding hamstring strength training in long length to usual physiotherapy Treatment caused increase in flexibility of dorsal and hamstrings muscles and improvement in low back pain.
