Abstract

Background and aim: Shortage and eventual weakeness of the ILIOPSOAS muscle is directly related to low back pain. Constant activity of the ILIOPSOAS in the straight posture along with its shortened position during sitting and lack of stretch of this muscle are probable causes of its shortening. This study aimed to determine the optimal duration of post isometric stretching to increase ILIOPSOAS FLEXIBILITY.Methods: Thirty-eight girl students, 20-26 years old, were recruited for this clinical trial by simple sampling from Zahedan University of medical sciences. Subjects were randomly assigned as either a 5 second stretch group or a 15 second stretch group. The range of active and passive hip extension and hip flexion (degrees) during THOMAS TEST were measured using Goniometer before and after 15 sessions of intervention. Post isometric stretching of ILIOPSOAS was carried out for 5 weeks, 3 times per week, lasting 2 min on each occasion for both groups. Data were analyzed using independent and paired t tests.Results: In 5 second stretch group, passive hip extension was increased from 11.7o±1.4o to 14.9o±0.96o and active hip extension was increased from 10.1o±1.58o to 13.7o±1.03o (p<0.001). In 15 second stretch group, passive hip extension was increased from 11.8o±2.4o to 16.3o±2.4o and active hip extension was increased from 9.7o±1.7o to 14.3o±2.05o (p<0.001). Hip flexion during THOMAS TEST was decreased from 14.4o±1.18o to 4.3o±1.4o and from 14.2o±3.3o to 4.1o±1.7o in 5 sec and 15 sec stretch groups, respectively (p<0.001).Conclusion: The results indicate that FLEXIBILITY of ILIOPSOAS and consequently the range of hip extension were increased and hip flexion during THOMAS TEST were significantly decreased using 5 second or 15 second STRETCH DURATION. No significant difference was found between two stretching duration in terms of muscle FLEXIBILITY.
