Abstract
PURPOSE: The benefits of providing static stretching exercise targeting the hips in patients with non-specific Low Back Pain (NSLBP) are not well established. The objective of the study was to verify the effects of static stretching on function, pain and range of motion on patients with non-specific Low Back Pain (NSLBP). METHODS:Thirty females with NSLBP were randomly assigned to two control (n = 15) and experimental (n = 15) groups. The experimental group received 3 stretch practice sessions per week for a period of 8 weeks. The Oswestry low back pain Disability Questionnaire (ODI), visual analog scale (VAS), and passive hip range of motion (PROM) were employed before and after the intervention. RESULTS: The results of mixed model analysis of variance indicate that the group × time interactions was not significant (p > 0.05) for all measurement outcomes. However, there was a main effect for Time (ODI: p = 0.002, VAS: p = 0.001, PROM-R: p = 0.016, PROM-L: p = 0.001). Such that the ODI, VAS, PROM-R, and PROM-L were showed significant differences before and after the intervention in the experimental group. CONCLUSIONS: The results demonstrated a significant difference in PROM, pain, and disability after 8 weeks of stretching exercises in participants with NSLBP and limited hip extension. Therefore, it would be reasonable to infer that NSLBP might be partly related to hip flexors tightness.
