Comparison of the effect of corrective exercises with gluteal to tensor activation index to upper and lower tensor 50 on pain, range of motion and two-dimensional kinematics of walking in women with chronic nonspecific low back pain

Introduction: Gluteal to tensor index indicates the electrical activition ratio of gluteal to tensor fasciae latae muscles, that the normalized electrical activity is used. The role of hip muscles in improving function and preventing injury is also considerable in the rehabilitation process of injury in patients with nonspecific chronic low back pain. This study aimed to compare the effect of corrective exercises with gluteal to tensor activation index above and below that 50 on pain, range of motion and two-dimensional kinematics of walking in women with chronic nonspecific low back pain. Methods: Forty-five women with nonspecific chronic low back pain age ranged from 30 to 45 years selected and were randomly divided into one of three groups of (control, n=15 and two experimental groups (corrective exercises with gluteal index to upper n= 15 and lower tensor n=15)). Exercise interventions were performed for eight weeks under the supervision of the researcher. In this study, which was a pre-test and post-test, visual analog scale, Roland Morris questionnaire, Goniometro video camera was used. Result: The results showed that both training interventions (correction exercises with gluteal index to tensor above and below 50) reduced pain, improved range of motion and kinematics of walking, but the group of gluteal index exercises to tensor above 50 effectiveness has greater improvement of the mentioned variables. Discussion: Findings indicate the superior effectiveness of gluteal to tensor index above 50 intervention group in reduction of pain, improvement of range of motion and kinematics of gait in relation to the other experimental group, therefore using this intervention as a complementary therapy along with other effective training interventions for patients with chronic nonspecific low back pain was recommended.
