Introduction: Gluteal index shows the ratio of electrical activity of gluteal muscles to tensor, which is a valid clinical index in the rehabilitation of diseases such as back pain. In this regard, the conservative treatment of non-specific chronic back pain patients with the therapeutic exercise approach has a special place in the rehabilitation of these patients, such as improving their walking pattern. Therefore, the aim of the present study was to compare the effect of rehabilitation exercises with and without focusing on the gluteal differentiation index on the walking kinematics of women with non-specific chronic back pain.
Methodology: The current research is a comparative-targeted type of intervention, which was considered as a pre-test and post-test in two experimental groups and one control group. The subjects of this research included 45 women with non-specific chronic back pain with an age range between 30 and 45 years, who had almost constant pain during at least the last three months. After selection, the subjects were randomly assigned to one of three control groups (15 people), group of exercises with gluteal index to upper tensor (15 people) and group of exercises with gluteal index to lower tensor (15 people). Exercise interventions were carried out for eight weeks under the supervision of the researcher. In this study, a video camera was used to evaluate the two-dimensional kinematics of walking. From the analysis of variance with repeated measures to investigate the interaction of group time, from the one-way analysis of variance, and Bonferroni's post hoc test to investigate the inter-group changes, as well as from the paired t-test to investigate the intra-group changes at a significance level of P≥0.05. SPSS version 21 statistical software was used to perform all calculations.
Results: Both training interventions were effective on improving walking kinematics (P<0.05), and considering the difference between groups in the two groups of gluteal to upper and lower tensor index exercises in improving walking kinematics, it should be stated that The influence of gluteal index exercises on tensor high was more in improving the mentioned variable. This was while the control group had no significant improvement and change in walking kinematics (P>0.05).
Conclusion: The findings of this research showed that the improvement of walking kinematics of women with non-specific chronic back pain in the gluteal index to high tensor exercise group was more than the gluteal index to low tensor exercise group. Therefore, it can be said that the use of gluteal index exercises for high tensor is more effective in the mentioned subjects.
