Determining correlation between chronic low back pain and muscular flexibility in pelvic and thigh region

Introduction. Many factors can produce chronic low back pain. The purpose of this study was determined correlation between flexibility of pelvic and thigh muscles and chronic low back pain. By means of comparison with control group. Also, sex as an affecting factor was studied. Materials and Methods. A total of 160 subjects (81 males and 76 females) with mean age 41.3 y/o included case group (n=56) with chronic low back pain and 104 healthy subjects as control group. Data collection was performed by a questionnaire and, measuring of flexibility of 15 muscles in both sides of pelvic and hip region. Statistical analysis was done by t-student and levins-test. Results. The results showed that flexibility of all muscles in patients with chronic low back pain were less than healthy ones, but only three muscles (erector spinae, piriformis, rectus femoris) were significant differences. Also male patients had less flexibility in pelvic and thigh muscles than female patients. Conclusion. Muscular flexibilityh is decreased in chronic low back pain. Therefore, a neccessory treatment in these patients is improvement of flexibility and streching techniques.
